Data Infrastructure and IT Industry Activity Trends

Some recent Industry Activities, Trends, News and Announcements include:

Arcserve who gained their independence from CA a few years ago has now acquired Zetta to expand its data protection solution portfolio for legacy, software defined virtual and cloud data infrastructure environments.

Software Defined Data Infrastructure (SDDI) solution provider Compuverde has been awarded a US Patent for optimal server selection in software defined data centers (SDDC).

The InfiniBand Trade Association (IBTA) announced its April 2017 integrators list including RDMA over Converged Ethernet (RoCE) along with other recent plugfest updates. Learn more about IBTA and related topics at www.infinibandta.org

Next Platform has an interesting piece about a slump in the High Performance Computing (HPC) also known as High Profit Compute (for financial firms among others) along with Super Compute (SC) industry sector. Some of the vendors in the HPC and SC space include AMD, Cisco, Cray, DDN, Dell EMC, Fujifilm, IBM, Intel, HPE/SGI, Mellanox, NetApp, Oracle, Seagate and Western Digital (WD) among others. Check out the piece over at Next Platform here.

To beef up its storage solution offerings, Cray has done a deal with Seagate who is one of their suppliers of HDDs as well as software defined storage software (ClusterStore) and related systems. In this new deal, Cray will get (e.g. now own) Lustre based ClusterStore storage solution which besides the intellectual property (IP) including software, around 100 or so workers will shift from being Seagate to becoming Cray employees. Note that Seagate acquired ClusterStore solution as part of its acquisition a few years ago of Xyratex (enclosures and Lustre storage system software).

Meanwhile Seagate CEO Stephen Luczo is steeping down from his top leadership position after posting poor earnings and more job cuts. We have heard that HDDs are dead for decades, yet they continue to be consumed, granted with ups and downs, lately more downs for Seagate than its competitor Western Digital (WD). Seagate has dabbled in flash solid state devices (SSDs) ranging from drives to cards including acquisition of the flash business from LSI/Avago a few years ago, along with some partnerships. As a component supplier, does Seagate need to take a bold move and get closer or do a deal with one of the nand flash or other persistent memory chip makers? Or, does Seagate need to continue to move up the stack with solutions building on their previous deals buying Xyratex (enclosure and ClusterStor), Evault (data protection software), DotHill (storage systems), LSI/Avago flash (flash cards)? Lets see what happens with Seagate both from a big picture as well as more focused product, technology, portfolio perspective.

Watch for a flurry of NVMe, along with flash SSD and other non-volatile memory (NVM), persistent memories along with storage class memories over the next few weeks. Keep in mind that If Answer is NVMe, what are the questions? Also watch for a flurry of software defined, cloud, virtual and related news towards the end of the month and into September.

Just for fun, Mike Acton (@mike_acton) has an interesting read on Introductory bullshit detection for non-technical managers that you can check out here. Over at Coding Horror there is another interesting read on the notion of paying down your technical debt, check it out here.

Get in the NVMe SSD game (if you are not already) with Intel 750 among others

Get in the NVMe SSD game (if you are not already)

Get in the NVMe SSD game. If you are or have talked the Non Volatile Memory (NVM) and NVM Express (NVMe) flash SSD talk, however have not yet done the walk, there are some good opportunities to do so.

One example how to start walking the talk is get something like the Intel 750 400GB NVMe PCIe Add in Card (AiC) which you should be able to find on different venues including Amazon for $400 USD or less (recently saw the 400GB version for about $309 USD delivered).

Of course the question might then be what to do with a NVMe device when you get it which besides running your applications on it, you can find some benchmark and workload generator tools, scripts and examples here.

NVMe ssd storage
Various NVM flash SSD including NVMe devices

Sure there are newer, more expensive, higher capacity cards, some are general availability (GA) while others are on early preview or evaluation basis.

However a good value, cost-effective way to get into the NVMe game, or expand your footprint are devices such as the Intel 750.

I have some of these cards and they have been great for use with various workloads. The Intel 750 cards are plug and play in various systems including my TS140s among larger robust servers running Windows Server (2012 R2, 2016 TP5), Ubuntu (various) and VMware ESXi (various).

There are in the box drivers for these Intel 750 cards, however to get a little more performance recommend visiting the Intel site, get the SSD tools, update the firmware on the cards if needed, as well as try the Intel vs. native drivers.

There are many vendors with NVMe PCIe cards, as well as U.2/SFF 8639 drives and M.2 mini-cards including Intel, Micron, Seagate, WD among many others

Where To Learn More

Additional learning experiences along with common questions (and answers), as well as tips can be found in Software Defined Data Infrastructure Essentials book.

Software Defined Data Infrastructure Essentials Book SDDC

What This All Means

Time to get in the NVMe game if you have not already done so moving from talking the talk to walking the talk. With cost of early generation NVMe devices such as the Intel 750 among others there are great opportunities to get started. On the other hand if you are already using NVMe, there are some good opportunities to add extra NVMe based SSD to other servers or systems.

Speaking of NVMe talk, join me and others on a panel (Session 303) moderated by Dr. Jay Metz (@drjmetz) August 11th at Flash Memory Summit where we will discuss NVMe including NVMe over fabric networks (e.g. moving beyond the PCIe bus). Also keep in mind, with NVMe the question is not if, rather when, where, why, how with what and how to coexist and leverage existing technologies, hardware, software and people skill sets.

Which enterprise HDD to use for content servers

This is the sixth in a multi-part series (read part five here) based on a white paper hands-on lab report I did compliments of Servers Direct and Seagate that you can read in PDF form here. The focus is looking at the Servers Direct (www.serversdirect.com) converged Content Solution platforms with Seagate Enterprise Hard Disk Drive (HDD’s). In this post the focus is around general I/O performance including 8KB and 128KB IOP sizes.

General I/O Performance

In addition to running database and file (large and small) processing workloads, Vdbench was also used to collect basic small (8KB) and large (128KB) sized I/O operations. This consisted of random and sequential reads as well as writes with the results shown below. In addition to using vdbench, other tools that could be used include Microsoft Diskspd, fio, iorate and iometer among many others.

These workloads used Vdbench configured (13) to do direct I/O to a Windows file system mounted device using as much of the available disk space as possible. All workloads used 16 threads and were run concurrently similar to database and file processing tests.

(Note 13) Sample vdbench configuration for general I/O, note different settings were used for various tests

Table-7 shows workload results for 8KB random IOPs 75% reads and 75% writes including IOPs, bandwidth and response time.

What This All Means

Some content applications are doing small random I/Os for database, key value stores or repositories as well as meta data processing while others are doing large sequential I/O. 128KB sized I/O may be large for your environment, on the other hand, with an increasing number of applications, file systems, software defined storage management tools among others, 1 to 10MB or even larger I/O sizes are becoming common. Key is selecting I/O sizes and read write as well as random sequential along with I/O or queue depths that align with your environment.

Continue reading part seven the final post in this multi-part series here where the focus is around how HDD’s continue to evolve including performance beyond traditional RPM based execrations along with wrap up.

Seagate 1200 12Gbs Enterprise SAS SSD StorgeIO lab review

Seagate 1200 12Gbs Enterprise SAS SSD StorgeIO lab review

This is the first post of a two part series, read the second post here.

Earlier this year I had the opportunity to test drive some Seagate 1200 12Gbs Enterprise SAS SSD’s as a follow-up to some earlier activity trying their Enterprise TurboBoost Drives. Disclosure: Seagate has been a StorageIO client and was also the sponsor of this white paper and associated proof-points mentioned in this post.

The question to ask yourself is not if flash Solid State Device (SSD) technologies are in your future, Instead the questions are when, where, using what, how to configure and related themes. SSD including traditional DRAM and NAND flash-based technologies are like real estate where location matters; however, there are different types of properties to meet various needs. This means leveraging different types of NAND flash SSD technologies in different locations in a complementary and cooperative aka hybrid way. For example nand flash SSD as part of an enterprise tiered storage strategy can be implemented server-side using PCIe cards, SAS and SATA drives as targets or as cache along with software, as well as leveraging SSD devices in storage systems or appliances.

Seagate 1200 SSD
Seagate 1200 Enterprise SAS 12Gbs SSD Image via Seagate.com

Another place where nand flash can be found and compliments SSD devices are so-called Solid State Hybrid Drives (SSHD) or Hybrid Hard Disk Drives (HHDD) including a new generation that accelerate writes as well as reads such as those Seagate refers to as with Enterprise TurboBoost. The Enterprise TurboBoost drives (view the companion StorageIO Lab review TurboBoost white paper here) were previously known as the Solid State Hybrid Drives (SSHD) or Hybrid Hard Disk Drives (HHDD). Read more about TurboBoost here and here.

The best server and storage I/O is the one you do not have to do

Keep in mind that the best server or storage I/O is that one that you do not have to do, with the second best being the one with the least overhead resolved as close to the processor (compute) as possible or practical. The following figure shows that the best place to resolve server and storage I/O is as close to the compute processor as possible however only a finite amount of storage memory located there. This is where the server memory and storage I/O hierarchy comes into play which is also often thought of in the context of tiered storage balancing performance and availability with cost and architectural limits.

Also shown is locality of reference which refers to how close data is to where it is being used and includes cache effectiveness or buffering. Hence a small amount of cache of flash and DRAM in the right location can have a large benefit. Now if you can afford it, install as much DRAM along with flash storage as possible, however if you are like most organizations with finite budgets yet server and storage I/O challenges, then deploy a tiered flash storage strategy.

Seagate 1200 12Gbs Enterprise SAS SSD’s

Back to the Seagate 1200 12Gbs Enterprise SAS SSD which is covered in this StorageIO Industry Trends Perspective thought leadership white paper. The focus of the white paper is to look at how the Seagate 1200 Enterprise class SSD’s and 12Gbps SAS address current and next generation tiered storage for virtual, cloud, traditional Little and Big Data infrastructure environments.

Seagate 1200 Enteprise SSD

This includes providing proof points running various workloads including Database TPC-B, TPC-E and Microsoft Exchange in the StorageIO Labs along with cache software comparing SSD, SSHD and different HDD’s including 12Gbs SAS 6TB near-line high-capacity drives.

Seagate 1200 Enterprise SSD Proof Points

The proof points in this white paper are from an applications focus perspective representing more of an end-to-end real-world situation. While they are not included in this white paper, StorageIO has run traditional storage building-block focus workloads, which can be found at StorageIOblog (Part II: How many IOPS can a HDD, HHDD or SSD do with VMware?). These include tools such as Iometer, iorate, vdbench among others for various IO sizes, mixed, random, sequential, reads, writes along with “hot-band" across different number of threads (concurrent users). “Hot-Band” is part of the SNIA Emerald energy effectiveness metrics for looking at sustained storage performance using tools such as vdbench. Read more about other various server and storage I/O benchmarking tools and techniques here.

For the following series of proof-points (TPC-B, TPC-E and Exchange) a system under test (SUT) consisted of a physical server (described with the proof-points) configured with VMware ESXi along with guests virtual machines (VMs) configured to do the storage I/O workload. Other servers were used in the case of TPC workloads as application transactional requester to drive the SQL Server database and resulting server storage I/O workload. VMware was used in the proof-points to reflect a common industry trend of using virtual server infrastructures (VSI) supporting applications including database, email among others. For the proof-point scenarios, the SUT along with storage system device under test were dedicated to that scenario (e.g. no other workload running) unless otherwise noted.

Server Storage I/O config

Microsoft Exchange Email proof-point configuration

For this proof-point, Microsoft Jet Stress Exchange performance workloads were placed (e.g. Exchange Database – EDB file) on each of the different devices under test with various metrics shown including activity rates and response time for reads as well as writes. For the Exchange testing, the EDB was placed on the device being tested while its log files were placed on a separate Seagate 400GB Enterprise 12Gbps SAS SSD.

Test configuration: Seagate 400GB 12000 2.5” SSD (ST400FM0073) 12Gbps SAS, 600GB 2.5” Enterprise 15K with TurboBoost™ (ST600MX) 6 Gbps SAS, 600GB 2.5” Enterprise Enhanced 15K V4 (15K RPM) HDD (ST600MP) with 6 Gbps SAS, Seagate Enterprise Capacity Nearline (ST6000NM0014) 6TB 3.5” 7.2K RPM HDD 12 Gbps SAS and 3TB 7.2K SATA HDD. Email server hosted as guest on VMware vSphere/ESXi V5.5, Microsoft SBS2011 Service Pack 1 64 bit. Guest VM (VMware vSphere 5.5) was on a SSD based dat, had a physical machine (host), with 14 GB DRAM, quad CPU (4 x 3.192GHz) Intel E3-1225 v300, with LSI 9300 series 12Gbps SAS adapters in a PCIe Gen 3 slot with Jet Stress 2010.  All devices being tested were Raw Device Mapped (RDM) where EDB resided. VM on a SSD based separate data store than devices being tested. Log file IOPs were handled via a separate SSD device also persistent (no delayed writes). EDB was 300GB and workload ran for 8 hours.

TPC-B (Database, Data Warehouse, Batch updates) proof-point configuration

SSD’s are a good fit for both transaction database activity with reads and write as well as query-based decision support systems (DSS), data warehouse and big data analytics. The following are proof points of SSD capabilities for database activity. In addition to supporting database table files and objects, along with transaction journal logs, other uses include for meta-data, import/export or other high-IO and write intensive scenarios. Two database workload profiles were tested including batch update (write-intensive) and transactional. Activity involved running Transaction Performance Council (TPC) workloads TPC-B (batch update) and TPC-E (transaction/OLTP simulate financial trading system) against Microsoft SQL Server 2012 databases. Each test simulation had the SQL Server database (MDF) on a different device with transaction log file (LDF) on a separate SSD. TPC-B for a single device results shown below.

TPC-B (write intensive) results below show how TPS work being done (blue) increases from left to right (more is better) for various numbers of simulated users. Also shown on the same line for each amount of TPS work being done is the average latency in seconds (right to left) where lower is better. Results are shown from top to bottom for each group of users (100, 50, 20 and 1) for the different drives being tested (top to bottom). Note how the SSD device does more work at a lower response time vs. traditional HDD’s

Test configuration: Seagate 400GB 12000 2.5” SSD (ST400FM0073) 12Gbps SAS, 600GB 2.5” Enterprise 15K with TurboBoost™ (ST600MX) 6 Gbps SAS, 600GB 2.5” Enterprise Enhanced 15K V4 (15K RPM) HDD (ST600MP) with 6 Gbps SAS, Seagate Enterprise Capacity Nearline (ST6000NM0014) 6TB 3.5” 7.2K RPM HDD 12 Gbps SAS and 3TB Seagate 7.2K SATA HDD Workload generator and virtual clients Windows 7 Ultimate 64 bit. Microsoft SQL Server 2012 database was on Windows 7 guest. Guest VM (VMware vSphere 5.5) had a dedicated 14 GB DRAM, quad CPU (4 x 3.192GHz) Intel E3-1225 v300, with LSI 9300 series 12Gbps SAS adapters in a PCIe Gen 3 slot along with TPC-B (www.tpc.org) workloads.

VM with guest OS along with SQL tempdb and masterdb resided on separate SSD based data store from devices being tested (e.g., where MDF (main database tables) and LDF (log file) resided). All devices being tested were Raw Device Mapped (RDM) independent persistent with database log file on a separate SSD device also persistent (no delayed writes) using VMware PVSCSI driver. MDF and LDF file sizes were 142GB and 26GB with scale factor of 10000, with each step running for one hour (10-minute preamble). Note that these proof-points DO NOT use VMware or any other third-party cache software or I/O acceleration tool technologies as those are covered later in a separate proof-point.

TPC-E (Database, Financial Trading) proof-point configuration

The following shows results from TPC-E test (OLTP/transactional workload) simulating a financial trading system. TPC-E is an industry standard workload that performs a mix of reads and writes database queries. Proof-points were performed with various numbers of users from 10, 20, 50 and 100 to determine (TPS) Transaction per Second (aka I/O rate) and response time in seconds. The TPC-E transactional results are shown for each device being tested across different user workloads. The results show how TPC-E TPS work (blue) increases from left to right (more is better) for larger numbers of users along with corresponding latency (green) that goes from right to left (less is better). The Seagate Enterprise 1200 SSD is shown on the top in the figure below with a red box around its results. Note how the SSD as a lower latency while doing more work compared to the other traditional HDD’s

VM with guest OS along with SQL tempdb and masterdb resided on separate SSD based data store from devices being tested (e.g., where MDF (main database tables) and LDF (log file) resided). All devices being tested were Raw Device Mapped (RDM) independent persistent with database log file on a separate SSD device also persistent (no delayed writes) using VMware PVSCSI driver. MDF and LDF file sizes were 142GB and 26GB with scale factor of 10000, with each step running for one hour (10-minute preamble). Note that these proof-points DO NOT use VMware or any other third-party cache software or I/O acceleration tool technologies as those are covered later in a separate proof-point.

Part II: Seagate 1200 12Gbs Enterprise SAS SSD StorgeIO lab review

Part II: Seagate 1200 12Gbs Enterprise SAS SSD StorgeIO lab review

This is the second post of a two part series, read the first post here.

Earlier this year I had the opportunity to test drive some Seagate 1200 12Gbs Enterprise SAS SSD’s as a follow-up to some earlier activity trying their Enterprise TurboBoost Drives. Disclosure: Seagate has been a StorageIO client and was also the sponsor of this white paper and associated proof-points mentioned in this post.

The Server Storage I/O Blender Effect Bottleneck

The earlier proof-points focused on SSD as a target or storage device. In the following proof-points, the Seagate Enterprise 1200 SSD is used as a shared read cache (write-through). Using a write-through cache enables a given amount of SSD to give a performance benefit to other local and networked storage devices.

traditional server storage I/O
Non-virtualized servers with dedicated storage and I/O paths.

Aggregation causes aggravation with I/O bottlenecks because of consolidation using server virtualization. The following figure shows non-virtualized servers with their own dedicated physical machine (PM) and I/O resources. When various servers are virtualized and hosted by a common host (physical machine), their various workloads compete for I/O and other resources. In addition to competing for I/O performance resources, these different servers also tend to have diverse workloads.

virtual server storage I/O blender
Virtual server storage I/O blender bottleneck (aggregation causes aggravation)

The figure above shows aggregation causing aggravation with the result being I/O bottlenecks as various applications performance needs converge and compete with each other. The aggregation and consolidation result is a blend of random, sequential, large, small, read and write characteristics. These different storage I/O characteristics are mixed up and need to be handled by the underlying I/O capabilities of the physical machine and hypervisor. As a result, a common deployment for SSD in addition to as a target device for storing data is as a cache to cut bottlenecks for traditional spinning HDD.

In the following figure a solution is shown introducing I/O caching with SSD to help mitigate or cut the effects of server consolation causing performance aggravations.

Addressing the VMware Server Storage I/O blender with cache

Addressing server storage I/O blender and other bottlenecks

For these proof-points, the goal was to create an I/O bottleneck resulting from multiple VMs in a virtual server environment performing application work. In this proof-point, multiple competing VMs including a SQL Server 2012 database and an Exchange server shared the same underlying storage I/O infrastructure including HDD’s The 6TB (Enterprise Capacity) HDD was configured as a VMware dat and allocated as virtual disks to the VMs. Workloads were then run concurrently to create an I/O bottleneck for both cached and non-cached results.

Server storage I/O with virtualization roof-point configuration topology

The following figure shows two sets of proof points, cached (top) and non-cached (bottom) with three workloads. The workloads consisted of concurrent Exchange and SQL Server 2012 (TPC-B and TPC-E) running on separate virtual machine (VM) all on the same physical machine host (SUT) with database transactions being driven by two separate servers. In these proof-points, the applications data were placed onto the 6TB SAS HDD to create a bottleneck, and a portion of the SSD used as a cache. Note that the Virtunet cache software allows you to use a part of a SSD device for cache with the balance used as a regular storage target should you want to do so.

If you have paid attention to the earlier proof-points, you might notice that some of the results below are not as good as those seen in the Exchange, TPC-B and TPC-E results about. The reason is simply that the earlier proof-points were run without competing workloads, and database along with log or journal files were placed on separate drives for performance. In the following proof-point as part of creating a server storage I/O blender bottleneck the Exchange, TPC-B as well as TPC-E workloads were all running concurrently with all data on the 6TB drive (something you normally would not want to do).

Solving the VMware Server Storage I/O blender with cache

The cache and non-cached mixed workloads shown above prove how an SSD based read-cache can help to reduce I/O bottlenecks. This is an example of addressing the aggravation caused by aggregation of different competing workloads that are consolidated with server virtualization.

For the workloads shown above, all data (database tables and logs) were placed on VMware virtual disks created from a dat using a single 7.2K 6TB 12Gbps SAS HDD (e.g. Seagate Enterprise Capacity).

The guest VM system disks which included paging, applications and other data files were virtual disks using a separate dat mapped to a single 7.2K 1TB HDD. Each workload ran for eight hours with the TPC-B and TPC-E having 50 simulated users. For the TPC-B and TPC-E workloads, two separate servers were used to drive the transaction requests to the SQL Server 2012 database.

For the cached tests, a Seagate Enterprise 1200 400GB 12Gbps SAS SSD was used as the backing store for the cache software (Virtunet Systems Virtucache) that was installed and configured on the VMware host.

During the cached tests, the physical HDD for the data files (e.g. 6TB HDD) and system volumes (1TB HDD) were read cache enabled. All caching was disabled for the non-cached workloads.

Note that this was only a read cache, which has the side benefit of off-loading those activities enabling the HDD to focus on writes, or read-ahead. Also note that the combined TPC-E, TPC-B and Exchange databases, logs and associated files represented over 600GB of data, there was also the combined space and thus cache impact of the two system volumes and their data. This simple workload and configuration is representative of how SSD caching can complement high-capacity HDD’s

Seagate 6TB 12Gbs SAS high-capacity HDD

While the star and focus of these series of proof-points is the Seagate 1200 Enterprise 12Gbs SAS SSD, the caching software (virtunet) and Enterprise TurboBoost drives also play key supporting and favorable roles. However the 6TB 12Gbs SAS high-capacity drive caught my attention from a couple of different perspectives. Certainly the space capacity was interesting along with a 12Gbs SAS interface well suited for near-line, high-capacity and dense tiered storage environments. However for a high-capacity drive its performance is what really caught my attention both in the standard exchange, TPC-B and TPC-E workloads, as well as when combined with SSD and cache software.

This opens the door for a great combination of leveraging some amount of high-performance flash-based SSD (or TurboBoost drives) combined with cache software and high-capacity drives such as the 6TB device (Seagate now has larger versions available). Something else to mention is that the 6TB HDD in addition to being available in either 12Gbs SAS, 6Gbs SAS or 6Gbs SATA also has enhanced durability with a Read Bit Error Rate of 10 ^15 (e.g. 1 second read error per 10^15 average attempts) and an AFR (annual failure rate) of 0.63% (See more speeds and feeds here). Hence if you are concerned about using large capacity HDD’s and them failing, make sure you go with those that have a high Read Bit Error Rate and a low AFR which are more common with enterprise class vs. lower cost commodity or workstation drives. Note that these high-capacity enterprise HDD’s are also available with Self-Encrypting Drive (SED) options.

Summary

Read more in this StorageIO Industry Trends and Perspective (ITP) white paper compliments of Seagate 1200 12Gbs SAS SSD’s and visit the Seagate Enterprise 1200 12Gbs SAS SSD page here. Moving forward there is the notion that flash SSD will be everywhere. There is a difference between all data on flash SSD vs. having some amount of SSD involved in preserving, serving and protecting (storing) information.

Key themes to keep in mind include:

  • Aggregation can cause aggravation which SSD can alleviate
  • A relative small amount of flash SSD in the right place can go a long way
  • Fast flash storage needs fast server storage I/O access hardware and software
  • Locality of reference with data close to applications is a performance enabler
  • Flash SSD everywhere does not mean everything has to be SSD based
  • Having some amount of flash in different places is important for flash everywhere
  • Different applications have various performance characteristics
  • SSD as a storage device or persistent cache can speed up IOPs and bandwidth

Flash and SSD are in your future, this comes back to the questions of how much flash SSD do you need, along with where to put it, how to use it and when.

Ok, nuff said (for now).

Seagate has shipped over 10 Million storage HHDD’s, is that a lot?

Seagate has shipped over 10 Million storage HHDD’s, is that a lot?

Recently Seagate made an announcement that they have shipped over 10 million Hybrid Hard Disk Drives (HHDD) also known as Solid State Hybrid Drives (SSHD) over that past few years. Disclosure Seagate has been a StorageIO client.

I know where some of those desktop class HHDD’s including Momentus XTs ended up as I bought some of the 500GB and 750GB models via Amazon and have them in various systems. Likewise I have installed in VMware servers the newer generation of enterprise class SSHD’s which Seagate now refers to as Turbo models as companions to my older HHDD’s

What is a HHDD or SSHD?

The HHDD’s continue to evolve from initially accelerating reads to now being capable of speeding up write operations across different families (desktop/mobile, workstation and enterprise). What makes a HHDD or SSHD is that as their name implies, they are a hybrid combing a traditional spinning magnetic Hard Disk Drive (HDD) along with flash SSD storage. The flash persistent memory is in addition to the DRAM or non-persistent memory typically found on HDDs used as a cache buffer. These HHDDs or SSHDs are self-contained in that the flash are built-in to the actual drive as part of its internal electronics circuit board (controller). This means that the drives should be transparent to the operating systems or hypervisors on servers or storage controllers without need for special adapters, controller cards or drivers. In addition, there is no extra software needed to automated tiering or movement between the flash on the HHDD or SSHD and its internal HDD, its all self-contained managed by the drives firmware (e.g. software).

Some SSHD and HHDD industry perspectives

Jim Handy over at Objective Analysis has this interesting post discussing Hybrid Drives Not Catching On. The following is an excerpt from Jim’s post.

Why were our expectations higher? 

There were a few reasons: The hybrid drive can be viewed as an evolution of the DRAM cache already incorporated into nearly all HDDs today. 

  • Replacing or augmenting an expensive DRAM cache with a slower, cheaper NAND cache makes a lot of sense.
  • An SSHD performs much better than a standard HDD at a lower price than an SSD. In fact, an SSD of the same capacity as today’s average HDD would cost about an order of magnitude more than the HDD. The beauty of an SSHD is that it provides near-SSD performance at a near-HDD price. This could have been a very compelling sales proposition had it been promoted in a way that was understood and embraced by end users.
  • Some expected for Seagate to include this technology into all HDDs and not to try to continue using it as a differentiator between different Seagate product lines. The company could have taken either of two approaches: To use hybrid technology to break apart two product lines – standard HDDs and higher-margin hybrid HDDs, or to merge hybrid technology into all Seagate HDDs to differentiate Seagate HDDs from competitors’ products, allowing Seagate to take slightly higher margins on all HDDs. Seagate chose the first path.

The net result is shipments of 10 million units since its 2010 introduction, for an average of 2.5 million per year, out of a total annual HDD shipments of around 500 million units, or one half of one percent.

Continue reading more of Jim’s post here.

In his post, Jim raises some good points including that HHDD’s and SSHD’s are still a fraction of the overall HDD’s shipped on an annual basis. However IMHO the annual growth rate has not been a flat average of 2.5 million, rather starting at a lower rate and then increasing year over year. For example Seagate issued a press release back in summer 2011 that they had shipped a million HHDD’s a year after their release. Also keep in mind that those HHDD’s were focused on desktop workstations and in particular, at Gamers among others.

The early HHDD’s such as the Momentus XTs that I was using starting in June 2010 only had read acceleration which was better than HDD’s, however did not help out on writes. Over the past couple of years there have been enhancements to the HHDD’s including the newer generation also known as SSHD’s or Turbo drives as Seagate now calls them. These newer drives include write acceleration as well as with models for mobile/laptop, workstation and enterprise class including higher-performance and high-capacity versions. Thus my estimates or analysis has the growth on an accelerating curve vs. linear growth rate (e.g. average of 2.5 million units per year).

 Units shipped per yearRunning total units shipped
2010-20111.0 Million1.0 Million
2011-20121.25 Million (est.)2.25 Million (est.)
2012-20132.75 Million (est.)5.0 Million (est.)
2013-20145.0 Million (est)10.0 Million

StorageIO estimates on HHDD/SSHD units shipped based on Seagate announcements

estimated hhdd and sshd shipments

However IMHO there is more to the story beyond numbers of HHDD/SSHD shipped or if they are accelerating in deployment or growing at an average rate. Some of those perspectives are in my comments over on Jim Handy’s site with an excerpt below.

In talking with IT professionals (e.g. what the vendors/industry calls users/customers) they are generally not aware that these devices exist, or if they are aware of them, they are only aware of what was available in the past (e.g. the consumer class read optimized versions). I do talk with some who are aware of the newer generation devices however their comments are usually tied to lack of system integrator (SI) or vendor/OEM support, or sole source. Also there was a focus on promoting the HHDD’s to “gamers” or other power users as opposed to broader marketing efforts. Also most of these IT people are not aware of the newer generation of SSHD or what Seagate is now calling “Turbo” drives.

When talking with VAR’s, there is a similar reaction which is discussion about lack of support for HHDD’s or SSHD’s from the SI/vendor OEMs, or single source supply concerns. Also a common reaction is lack of awareness around current generation of SSHD’s (e.g. those that do write optimization, as well as enterprise class versions).

When talking with vendors/OEMs, there is a general lack of awareness of the newer enterprise class SSHD’s/HHDD’s that do write acceleration, sometimes there is concern of how this would disrupt their “hybrid” SSD + HDD or tiering marketing stories/strategies, as well as comments about single source suppliers. Have also heard comments to the effect of concerns about how long or committed are the drive manufactures going to be focused on SSHD/HHDD, or is this just a gap filler for now.

Not surprisingly when I talk with industry pundits, influencers, amplifiers (e.g. analyst, media, consultants, blogalysts) there is a reflection of all the above which is lack of awareness of what is available (not to mention lack of experience) vs. repeating what has been heard or read about in the past.

IMHO while there are some technology hurdles, the biggest issue and challenge is that of some basic marketing and business development to generate awareness with the industry (e.g. pundits), vendors/OEMs, VAR’s, and IT customers, that is of course assuming SSHD/HHDD are here to stay and not just a passing fad…

What about SSHD and HHDD performance on reads and writes?

What about the performance of today’s HHDD’s and SSHD’s, particular those that can accelerate writes as well as reads?

Closing comments and perspectives

I continue to be bullish on hybrid storage solutions from cloud, to storage systems as well as hybrid-storage devices. However like many technology just because something makes sense or is interesting does not mean its a near-term or long-term winner. My main concern with SSHD and HHDD is if the manufactures such as Seagate and WD are serious about making them a standard feature in all drives, or simply as a near-term stop-gap solution.

What’s your take or experience with using HHDD and/or SSHDs?

June 2014 Server and StorageIO Update newsletter

Server and StorageIO Update newsletter – June 2014

Welcome to the June 2014 edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization and data infrastructure topics. June has been busy on many fronts with lots of activities, not to mention spring and summer are finally here in the Stillwater MN area.

Speaking of busy, the spring rains came a month or two late, or the summer storms early as we will end up with one of the, if not rainiest Junes in history here in Stillwater MN area.

Greg Schulz Storage I/OGreg Schulz @StorageIO

Industry and Technology Updates

There has also been plenty of activity in the Information Technology (IT) and in particular the data infrastructure sector (databases, file systems, operating systems, servers, storage, I/O networking, cloud, virtualization, SSD, data protection and DCIM among others). SANdisk announced their intention to buy SSD vendor Fusion IO for a $1.1 Billion dollars as part of a continued flash consolidation trend For example Cisco buys Whiptail, WD buys Virident, Seagate buys Avago/LSI Flash division among others (read more about flash SSD here). Even with flash SSD vendor and technology consolidation, this is in no way an indication of the health of the market. Quite the opposite in that flash SSD has a very bright future and we are still in the relative early phase or waves and flash will be in your future. The question remains how much, when, where, with what and from whom. Needless to say there is plenty of SSD related hardware and software activity occurring in the StorageIO labs as well as StorageIO.com/SSD;).

StorageIO Industry Trends and Perspectives

NetApp Updates

In early June I was invited by NetApp to attend their annual analyst summit along with many others from around the world for a series of briefings, NDA updates and other meetings. Disclosure NetApp has been a client in the past and covered travel and lodging expenses to attend their event.

While the material under NDA naturally can not be discussed, there was discussion around NetApp previously announced earnings, their continued relationship with IBM (for the E Series) along with the June product updates. Shortly after the NetApp event they announced enhancements to there ONTAP FAS based systems that followup to those released earlier this year. These recent enhancements NetApp claims as being their fastest FAS based systems ever.

Given the success NetApp has had with their ONTAP FAS based systems including with FlexPod, it should not be a surprise that they continue to focus on those as their flagship offerings. What was clear from listening to CEO Tom Georgens is that NetApp as a company needs to offer, promote and sell the entire portfolio including E Series (disk, hybrid and all flash EF), StorageGrid (bycast), FlexPod and FAS among other tools (software defined storage management) and services (for legacy, virtual and cloud). Watch for some interesting updates and enhancements for the above and other things from NetApp in the future.

Staying busy is a good thing

What have I been doing during June 2014 to stay busy besides getting ready for summer fun (as well as preparing for fall industry events) including in and around the water?

  • Presented several BrightTalk Webinars (see events below) with more coming up
  • Release of new ITP white paper and StorageIO lab proof points with more in the works
  • More videos and pod casts, technology reviews including servers among other things
  • Moderated a software defined panel discussion at MSP area VMUG
  • Providing industry commentary in different venues (see below)
  • Not to mention various client consulting projects

What’s in the works?

Several projects and things are in the works that will show themselves in the coming weeks or months if not sooner. Some of which are more proof points coming out of the StorageIO labs involving software defined, converged, cloud, virtual, SSD, data protection and more.

Speaking of Software Defined, join me for a free Spiceworks Webinar on July 2, Do More with Less Hardware Using Software Defined Storage Management (sponsored by Starwind Software).

    Fall 2013 StorageIO Update Newsletter

    Storage I/O trends

    Fall 2013 StorageIO Update Newsletter

    Welcome to the Fall 2013 (joint September and October) edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization and data infrastructure topics. It is fall (at least here in north America) which means conferences, symposium, virtual and physical events, seminars, webinars in addition to normal client project activities. Starting with VMworld back in late August, that event occurred in San Francisco which kicked off the fall (or back to school) season of activity. VMworld was followed with many other events including in-person along with virtual or on-line such as webinars, Google+ hangouts among others, not to mention all the briefings for vendor product announcements and updates. Check out the industry trends perspectives articles, comments and blog posts below that covers some activity over the past few months.

    VMworld 2013
    Congratulations to VMworld on the 10th anniversary of the event. With the largest installment yet of a VMworld in terms of attendance, there were also many announcements. Here are a synopsis of some of those announcements which of course included plenty of software defined marketing (SDM).

    CMG and Storage Performance
    During mid-September I was invited to give an industry trends and perspectives presentation to the Storage Performance Council (SPC) board. The SPC board were meeting in the Minneapolis area and I gave a brief talk about Metrics that Matter and importance of context with focus on applications. Speaking of the Minneapolis area, Tom Becchetti (@tbecchetti) organized a great CMG event hosted over at Blue Cross Blue Shield of Minnesota. I gave a discussion around Technolutionary, technology evolution and revolution, using old and new things in new ways.

    Check out our backup, restore, BC, DR and archiving (Under the resources section on StorageIO.com) for various presentation, book chapter downloads and other content.

    SNW Fall 2013 Long Beach
    Talking about traveling, there was a quick trip out to Long Beach for the fall 2013 edition of Storage Networking World (SNW) where I had some good meetings and conversations with those who were actually there. No need to sugar coat it, likewise no need to kick sand in its face. Plain and simple, SNW is not the event it used to be has been a common discussion theme for several years which I had set my expectation accordingly.

    Some have asked me why I even spent time, money and resources to attend SNW?

    My answer is that I had some meetings to attend to, wanted to see and meet with others who were going to be there, and perhaps even say goodbye to an event that I have been involved with for over a decade.

    Does that mean I’m all done with SNW?

    Not sure yet as will have to wait and see what SNIA and IDG/Computerworld the event co-owners and producers put together for future events. However there are enough other events and activities to pick up the slack which is part of what has caused the steady decline in events like SNW among others.

    Perhaps it is time for SNIA to partner with another adjacent yet like-minded organization such as CMG to collaborate and try doing something like what was done in the early 2000s? That is SNIA providing their own seminars along with others such as myself who involved with both CMG, SNW and SNIA to beef up or set up a storage and I/O focused track at the CMG event.

    Beyond those items mentioned above, or in the following section, there are plenty of interesting and exciting things occurring in the background that I cant talk about yet. However watch for future posts, commentary, perspectives and other information down the road (and in the not so distant future).

    Enjoy this edition of the StorageIO Update newsletter.

    Brouwer Storage Consultancy

    StorageIO in Europe (Netherlands)
    Spent over a week in the Netherlands where I presented three different seminar workshop sessions organized by Brouwer Storage Consultancy who is celebrating their 10th anniversary in business. These sessions spanned five full days of interactive discussions with an engaged diverse group of attendees in the Nijkerk area who came from across Holland to take part in these workshops.

    Congratulations to Gert and Frank Brouwer on their ten years of being in business and best wishes for many more. Fwiw those who are curious StorageIO will be ten years young in business in about two years.

    StorageIO Industry Trends and Perspectives

    Some observations from while in Europe:

    Continued cloud privacy concerns amplified by NSA and suspicion of US-based companies, yet many are not aware of similar concerns of European or UK-based firms from those outside those areas. While there were some cloud concern conversations over the demise of Nirvanix, those seemed less so then in the media or US given that at least in Holland they have seen other cloud and storage as a service firms come and go already. It should be noted that the US has also seen cloud and storage as a service startups come and go, however I think sometimes we or at least the media tends to have a short if not selective memory at times.

    In one of our workshops sessions we were talking about service level objectives (SLO), service level agreements (SLA), recovery point objectives (RPO) and recovery time objectives (RTO) among other themes. Somebody mentioned why the focus of time in RPO and questions why not a transactional perspective which I thought was a brilliant question. We had a good conversation in the group and concurred that while RPO is what the industry uses, that there also needs to be a transactional state context tie to what is inferred or assumed with RPO and RTO. Thus the importance of looking beyond just the point in time, however the importance of a transactional context or state, such as not just the time, however to a given transactional point.

    Note that transactional could mean database, file system, backup or data protection index or catalog, meta data repository or other entity. This is where some should be jumping up and down like Donkey in Shrek wanting to point out that is exactly what RTO and RPO refer to which would be great. However all to often what is assumed is not conveyed, thus those who don’t know, well, they assume or simply don’t know what others.

    StorageIO Industry Trends and Perspectives

    Data Dynamics StorageX 7.0 Intelligent Policy Based File Data Migration – There is no such thing as a data or information recession . Likewise, people and data are living longer as well as getting larger. These span various use cases from traditional to personal or at work productivity. From little to big data content, collaboration including file or document sharing to rich media applications all of which are leveraging unstructured data. For example, email, word processing back-office documents, web and text files, presentations (e.g. PowerPoint), photos, audio and video among others. These macro trends result in the continued growth of unstructured Network Attached Storage (NAS) file data.

    Thus, a common theme is adding management including automated data movement and migration to carry out structure around unstructured NAS file data. More than a data mover or storage migration tool, Data Dynamics StorageX is a software platform for adding storage management structure around unstructured local and distributed NAS file data. This includes heterogeneous vendor support across different storage system, protocols and tools including Windows CIFS and Unix/Linux NFS.

    Seagate Kinetic Cloud and Object Storage I/O platform (and Ethernet HDD)

    Storage I/O trends

    Seagate Kinetic Cloud and Object Storage I/O platform

    Seagate announced today their Kinetic platform and drive designed for use by object API accessed storage including for cloud deployments. The Kinetic platform includes Hard Disk Drives (HDD) that feature 1Gb Ethernet (1 GbE) attached devices that speak object access API or what Seagate refers to as a key / value.

    Seagate Kinetic architecture

    What is being announced with Seagate Kinetic Cloud and Object (Ethernet HDD) Storage?

    • Kinetic Open Storage Platform – Ethernet drives, key / value (object access) API, partner software
    • Software developer’s kits (SDK) – Developer tools, documentation, drive simulator, code libraries, code samples including for SwiftStack and Riak.
    • Partner ecosystem

    What is Kinetic?

    While it has 1 GbE ports, do not expect to be able to use those for iSCSI or NAS including NFS, CIFS or other standard access methods. Being Ethernet based, the Kinetic drive only supports the key value object access API. What this means is that applications, cloud or object stacks, key value and NoSQL data repositories, or other software that adopt the API can communicate directly using object access.

    Seagate Kinetic storage

    Internal, the HDD functions as a normal drive would store and accessing data, the object access function and translation layer shifts from being in an Object Storage Device (OSD) server node to inside the HDD. The Kinetic drive takes on the key value API personality over 1 GbE ports instead of traditional Logical Block Addressing (LBA) and Logical Block Number (LBN) access using 3g, 6g or emerging 12g SAS or SATA interfaces. Instead Kinetic drives respond to object access (aka what Seagate calls key / value) API commands such as Get, Put among others. Learn more about object storage, access and clouds at www.objectstoragecenter.com.

    Storage I/O trends

    Some questions and comments

    Is this the same as what was attempted almost a decade ago now with the T10 OSD drives?

    Seagate claims no.

    What is different this time around with Seagate doing a drive that to some may vaguely resemble the predecessor failed T10 OSD approach?

    Industry support for object access and API development have progressed from an era of build it and they will come thinking, to now where the drives are adapted to support current cloud, object and key value software deployment.

    Wont 1GbE ports be too slow vs. 12g or 6g or even 3g SAS and SATA ports?

    Keep in mind those would be apples to oranges comparisons based on the protocols and types of activity being handled. Kinetic types of devices initially will be used for large data intensive applications where emphasis is on storing or retrieving large amounts of information, vs. low latency transactional. Also, keep in mind that one of the design premises is to keep cost low, spread the work over many nodes, devices to meet those goals while relying on server-side caching tools.

    Storage I/O trends

    Does this mean that the HDD is actually software defined?

    Seagate or other HDD manufactures have not yet noticed the software defined marketing (SDM) bandwagon. They could join the software defined fun (SDF) and talk about a software defined disk (SDD) or software defined HDD (SDHDD) however let us leave that alone for now.

    The reality is that there is far more software that exists in a typical HDD than what is realized. Sure some of that is packaged inside ASICs (Application Specific Integrated Circuits) or running as firmware that can be updated. However, there is a lot of software running in a HDD hence the need for power yet energy-efficient processors found in those devices. On a drive per drive basis, you may see a Kinetic device consume more energy vs. other equivalence HDDs due to the increase in processing (compute) needed to run the extra software. However that also represents an off-load of some work from servers enabling them to be smaller or do more work.

    Are these drives for everybody?

    It depends on if your application, environment, platform and technology can leverage them or not. This means if you view the world only through what is new or emerging then these drives may be for all of those environments, while other environments will continue to leverage different drive options.

    Object storage access

    Does this mean that block storage access is now dead?

    Not quite, after all there is still some block activity involved, it is just that they have been further abstracted. On the other hand, many applications, systems or environments still rely on block as well as file based access.

    What about OpenStack, Ceph, Cassandra, Mongo, Hbase and other support?

    Seagate has indicated those and others are targeted to be included in the ecosystem.

    Seagate needs to be careful balancing their story and message with Kinetic to play to and support those focused on the new and emerging, while also addressing their bread and butter legacy markets. The balancing act is communicating options, flexibility to choose and adopt the right technology for the task without being scared of the future, or clinging to the past, not to mention throwing the baby out with the bath water in exchange for something new.

    For those looking to do object storage systems, or cloud and other scale based solutions, Kinetic represents a new tool to do your due diligence and learn more about.

    Cisco buys Whiptail continuing the SSD storage I/O flash cash cache dash

    Storage I/O trends

    Cisco buys Whiptail continuing the Storage storage I/O flash cash cache dash

    Congratulations to Virident for being bought today for $645 Million USD by Western Digital (WD). Virident a nand flash PCIe card startup vendor has been around for several years and in the last year or two has gain more industry awareness as a competitor to FusionIO among others.

    There is a nand flash solid state devices (SSD) cash-dash occurring, not to mention fast cache dances that is occurring the IT and data infrastructure (e.g. storage and IO) sector specifically.

    Why the nand flash SSD cash dash and cache dance?

    Yesterday hard disk drive (HDD) vendor Western Digital (WD) bought Virident a nand flash PCIe Solid State Device (SSD) card vendor for $650M, and today networking and server vendor Cisco bought Whiptail a SSD based storage system startup for a little over $400M. Here is an industry trends perspective post that I did yesterday on WD and Virident.

    Obviously this begs a couple of questions, some of which I raised in my post yesterday about WD, Virident, Seagate, FusionIO and others.

    Questions include

    Does this mean Cisco is getting ready to take on EMC, NetApp, HDS and its other storage partners who leverage the Cisco UCS server?

    IMHO at least near term no more than they have in the past, nor any more than EMCs partnership with Lenovo indicates a shift in what is done with vBlocks. On the other hand, some partners or customers may be as nervous as a long-tailed cat next to a rocking chair (Google it if you don’t know what it means ;).

    Is Cisco going to continue to offer Whiptail SSD storage solutions on a standalone basis, or pull them in as part of solutions similar to what it has done on other acquisitions?

    Storage I/O trends

    IMHO this is one of the most fundamental questions and despite the press release and statements about this being a UCS focus, a clear sign of proof for Cisco is how they reign in (if they go that route) Whiptail from being sold as a general storage solution (with SSD) as opposed to being part of a solution bundle.

    How will Cisco manage its relationship in a coopitition manner cooperating with the likes of EMC in the joint VCE initiative along with FlexPod partner NetApp among others? Again time will tell.

    Also while most of the discussions about NetApp have been around the UCS based FlexPod business, there is the other side of the discussion which is what about NetApp E Series storage including the SSD based EF540 that competes with Whiptail (among others).

    Many people may not realize how much DAS storage including fast SAS, high-capacity SAS and SATA or PCIe SSD cards Cisco sells as part of UCS solutions that are not vBlock, FlexPod or other partner systems.

    NetApp and Cisco have partnerships that go beyond the FlexPod (UCS and ONTAP based FAS) so will be interesting to see what happens in that space (if anything). This is where Cisco and their UCS acquiring Whiptail is not that different from IBM buying TMS to complement their servers (and storage) while also partnering with other suppliers, same holds true for server vendors Dell, HP, IBM and Oracle among others.

    Can Cisco articulate and convince their partners, customers, prospects and others that the whiptail acquisition is more about direct attached storage
    (DAS) which includes both internal dedicated and external shared device?

    Keep in mind that DAS does not have to mean Dumb A$$ Storage as some might have you believe.

    Then there are the more popular questions of who is going to get bought next, what will NetApp, Dell, Seagate, Huawei and a few others do?

    Oh, btw, funny how have not seen any of the pubs mention that Whiptail CEO Dan Crain is a former Brocadian (e.g. former Brocade CTO) who happens to be a Cisco competitor, just saying.

    Congratulations to Dan and his crew and enjoy life at Cisco.

    Stay tuned as the fall 2013 nand flash SSD cache dash and cash dance activities are well underway.

    Ok, nuff said (for now).

    Cheers

    WD buys nand flash SSD storage I/O cache vendor Virident

    Storage I/O trends

    WD buys nand flash SSD storage I/O cache vendor Virident

    Congratulations to Virident for being bought today for $645 Million USD by Western Digital (WD). Virident a nand flash PCIe card startup vendor has been around for several years and in the last year or two has gain more industry awareness as a competitor to FusionIO among others.

    There is a nand flash solid state devices (SSD) cash dash occurring, not to mention fast cache dances that is occurring the IT and data infrastructure (e.g. storage and IO) sector specifically.

    Why the nand flash SSD cash dash and cache dance?

    Here is a piece that I did today over at InfoStor on a related theme that sets the basis of why the nand flash-based SSD market is popular for storage and as a cache. Hence there is a flash cash dash and by some dance for increased storage I/O performance.

    Like the hard disk drive (HDD) industry before it which despite what some pundits and profits have declared (for years if not decades) as being dead (it is still alive), there were many startups, shutdowns, mergers and acquisitions along with some transformations. Granted solid-state memories is part of the presence and future being deployed in new and different ways.

    The same thing has occurred in the nand flash-based SSD sector with LSI acquiring SANDforce, SANdisk picking up Pliant and Flashsoft among others. Then there is Western Digital (WD) that recently has danced with their cash as they dash to buy up all things flash including Stec (drives & PCIe cards), Velobit (cache software), Virident (PCIe cards), along with Arkeia (backup) and an investment in Skyera.

    Storage I/O trends

    What about industry trends and market dynamics?

    Meanwhile there have been some other changes with former industry darling and highflying stock post IPO FusionIO hitting as market reality and sudden CEO departure a few months ago. However after a few months of their stock being pummeled, today it bounced back perhaps as people now speculate who will buy FusionIO with WD picking up Virident. Note that one of Viridents OEM customers is EMC for their PCIe flash card XtremSF as are Micron and LSI.

    Meanwhile Stec, also  now own by WD was also EMCs original flash SSD drive supplier or what they refer to as a EFDs (Electronic Flash Devices), not to mention having also supplied HDDs to them (also keep in mind WD bought HGST a year or so back).

    There are some early signs as well as their stock price jumping today which was probably oversold. Perhaps people are now speculating that maybe Seagate who had been an investor in Virident which was bought by WD for $645 million today might be in the market for somebody else? Alternatively, that perhaps WD didn’t see the value in a FusionIO, or willing to make big flash cache cash grabs dash of that size? Also note Seagate won a $630 million (and the next appeal was recently upheld) infringement lawsuit vs. WD (here and here).

    Does that mean FusionIO could become Seagate’s target or that of NetApp, Oracle or somebody else with the cash and willingness to dash, grab a chunk of the nand flash, and cache market?

    Likewise, there are the software I/O and caching tool vendors some of which are tied to VMware and virtual servers vs. others that are more flexible that are gaining popularity. What about the systems or solution appliances play, could that be in the hunt for a Seagate?

    Anything is possible however IMHO that would be a risky move, one that many at Seagate probably still remember from their experiment with Xiotech, not to mention stepping on the toes of their major OEM customer partners.

    Storage I/O trends

    Thus I would expect Seagate if they do anything would be more along the lines of a component type suppler meaning a FusionIO (yes they have Nexgen, however that could be easily dealt with), OCZ, perhaps even a LSI or Micron however some of those start to get rather expensive for a quick flash cache grab for some stock and cash.

    Also, keep in mind that FusionIO in addition to having their PCIe flash cards also have the ioturbine software-caching tool that if you are not familiar with, IBM recently made an announcement of their Flash Cache Storage Accelerator (FCSA) that has an affiliation to guess who?

    Closing comments (for now)

    Some of the systems or solutions players will survive, perhaps even being acquired as XtremIO was by EMC, or file for IPO like Violin, or express their wish to IPO and or be bought such as all the others (e.g. Skyera, Whiptail, Pure, Solidfire, Cloudbyte, Nimbus, Nimble, Nutanix, Tegile, Kaminario, Greenbyte, and Simplivity among others).

    Here’s the thing, those who really do know what is going to happen are not and probably cannot say, and those who are talking what will happen are like the rest of us, just speculating or providing perspectives or stirring the pot among other things.

    So who will be next in the flash cache ssd cash dash dance?

    Ok, nuff said (for now).

    Seagate provides proof of life: Enterprise HDD enhancements

    Storage I/O trends

    Proof of life: Enterprise Hard Disk Drives (HDD’s) are enhanced

    Last week while hard disk drive (HDD) competitor Western Digital (WD) was announcing yet another (Velobit) in a string of acquisitions ( e.g. earlier included Stec, Arkeia) and investments (Skyera), Seagate announced new enterprise class HDD’s to their portfolio. Note that it was only two years ago that WD acquired Hitachi Global Storage Technologies (HGST) the disk drive manufacturing business of Hitachi Ltd. (not to be confused with HDS).

    Seagate

    Similar to WD expanding their presence in the growing nand flash SSD market, Seagate also in May of this year extended their existing enterprise class SSD portfolio. These enhancements included new drives with 12Gbs SAS interface, along with a partnership (and investment) with PCIe flash card startup vendor Virident. Other PCIe flash SSD card vendors (manufacturers and OEMs) include Cisco, Dell, EMC, FusionIO, HP, IBM, LSI, Micron, NetApp and Oracle among others.

    These new Seagate enterprise class HDD’s are designed for use in cloud and traditional data center servers and storage systems. A month or two ago Seagate also announced new ultra-thin (5mm) client (aka desktop) class HDD’s along with a 3.5 inch 4TB video optimized HDD. The video optimized HDD’s are intended for Digital Video Recorders (DVR’s), Set Top Boxes (STB’s) or other similar applications.

    What was announced?

    Specifically what Seagate announced were two enterprise class drives, one for performance (e.g. 1.2TB 10K) and the other for space capacity (e.g. 4TB).

    Advanced Format (AF) 4K block in addition to standard 512 byte sectors

    Use cases

    Replace earlier generation 3.5” 15K SAS and Fibre Channel HDD’s for higher performance applications including file systems, databases where SSD are not practical fit.

    Backup and data protection, replication, copy operations for erasure coding and data dispersal, active in dormant archives, unstructured NAS, big data, data warehouse, cloud and object storage.

    Note the Seagate Terascale has a disk rotation speed of 5,900 (5.9K RPM) which is not a typo given the more traditional 5.4K RPM drives. This slight increase in performance from 5.4K to 5.9K should give when combined with other enhancements (e.g. firmware, electronics) to boost performance for higher capacity workloads.

    Let us watch for some performance numbers to be published by Seagate or others. Note that I have not had a chance to try these new drives yet, however look forward to getting my hands on them (among others) sometime in the future for a test drive to add to the growing list found here (hey Seagate and WD, that’s a hint ;) ).

    What this all means?

    Storage I/O trends

    Wait, weren’t HDD’s supposed to be dead or dying?

    Some people just like new and emerging things and thus will declare anything existing or that they have lost interest in (or their jobs need it) as old, boring or dead.

    For example if you listen to some, they may say nand flash SSD are also dead or dying. For what it is worth, imho nand flash-based SSDs still have a bright future in front of them even with new technologies emerging as they will take time to mature (read more here or listen here).

    However, the reality is that for at least the next decade, like them or not, HDD’s will continue to play a role that is also evolving. Thus, these and other improvements with HDD’s will be needed until current nand flash or emerging PCM (Phase Change Memory) among other forms of SSD are capable of picking up all the storage workloads in a cost-effective way.

    Btw, yes, I am also a fan and user of nand flash-based SSD’s, in addition to HDD’s and see roles for both as being viable complementing each other for traditional, virtual and cloud environments.

    In short, HDD’s will keep spinning (pun intended) for some time granted their roles and usage will also evolve similar to that of tape summit resources.

    Storage I/O trends

    With this announcement by Seagate along with other enhancements from WD show that the HDD will not only see its 60th birthday, (and here), it will probably also easily see its 70th and not from the comfort of a computer museum. The reason is that there is yet another wave of HDD improvements just around the corner including Shingled Magnetic Recording (SMR) (more info here) along with Heat Assisted Magnetic Recording (HAMR) among others. Watch for more on HAMR and SMR in future posts. With these and other enhancements, we should be able to see a return to the rapid density improvements with HDD’s observed during the mid to late 2000 era when Perpendicular recording became available.

    What is up with this ISE stuff is that the same as what Xiotech (e.g. XIO) had?

    Is this the same technology that Xiotech (now Xio) referred to the ISE the answer is no. This Seagate ISE is for fast secure erase of data on disk. The benefit of Instant Secure Erase (ISE) is to cut from hours or days the time required to erase a drive for secure disposal to seconds (or less). For those environments that already factor drives erase time as part of those overall costs, this can increase the useful time in service to help improve TCO and ROI.

    Wait a minute, aren’t slower RPM’s supposed to be lower performance?

    Some of you might be wondering or asking the question of wait, how can a 10,000 revolution per minute (10K RPM) HDD be considered fast vs. a 15K HDD, let alone SSD?

    Storage I/O trends

    There is a trend occurring with HDD’s that the old rules of IOPS or performance being tied directly to the size and rotational speed (RPM’s) of drives, along with their interfaces. This comes down to being careful to judge a book or in this case a drive by its cover. While RPM’s do have an impact on performance, new generation drives at 10K such as some 2.5” models are delivering performance equal to or better than earlier generation 3.5” 15K device’s.

    Likewise, there are similar improvements with 5.4K devices vs. previous generation 7.2K models. As you will see in some of the results found here, not all the old rules of thumbs when it comes to drive performance are still valid. Likewise, keep those metrics that matter in the proper context.


    Click on above image to see various performance results

    For example as seen in the results (above), the more DRAM or DDR cache on the drives has a positive impact on sequential reads which can be good news if that is what your applications need. Thus, do your homework and avoid judging a device simply by its RPM, interface or form factor.

    Other considerations, temperature and vibration

    Another consideration is that with increased density of more drives being placed in a given amount of space, some of which may not have the best climate controls, humidity and vibration are concerns. Thus, the importance of drives having vibration dampening or safeguards to keep up performance are important. Likewise, even though drive heads and platters are sealed, there are also considerations that need to be taken care of for humidity in data center or cloud service providers in hot environments near the equator.

    If this is not connecting with you, think about how close parts of Southeast Asia and the India subcontinent are to the equator along with the rapid growth and low-cost focus occurring there. Your data center might be temperature and humidity controlled, however others who very focused on cost cutting may not be as concerned with normal facilities best practices.

    What type of drives should be used for cloud, virtual and traditional storage?

    Good question and one where the answer should be it depends upon what you are trying or need to do (e.g. see previous posts here or here and here (via Seagate)).For example here are some tips for big data storage and storage making decisions in general.

    Disclosure

    Seagate recently invited me along with several other industry analysts to their cloud storage analyst summit in San Francisco where they covered roundtrip coach airfare, lodging, airport transfers and a nice dinner at the Epic Roast house.

    I also have received in the past a couple of Momentus XT HHDD (aka SSHD) from Seagate. These are in addition to those that I bought including various Seagate, WD along with HGST, Fujitsu, Toshiba and Samsung (SSD and HDD’s) that I use for various things.

    Ok, nuff said (for now).

    More Storage IO momentus HHDD and SSD moments part II

    This follows the first of a two-part series on my latest experiences with Hybrid Hard Disk Drives (HHDD’s) and Solid State Devices (SSD’s). In my ongoing last momentus moment post I discussed what I have done with HHDD’s and setting the stage for expanded SSD use. I have the newer HHDD’s, e.g. Seagate Momentus XT II 750GB (8GB SLC nand flash) installed and have since bought another from Amazon as well as having some of the older 500GB (4GB SLC nand flash) in various systems. Those are all functioning great, however still waiting and looking forward to the rumored firmware enhancements to boost write capabilities.

    This brings me up to the latest momentus moment which now includes SSD’s.

    Well its two years later and I now have a 256GB (usable capacity is lower) Samsung SSD that I bought from Amazon.com and installed in one of my laptops and just as when I made the first switch to HHDD’s, I also have a backup copy/clone to fall back to in case of emergency.

    Was it worth the wait? Yes, particularly using the HHDD’s to bridge the gap and enable some productivity gain which more than paid for them based on some different projects. I’m already seeing productivity improvements that will make future upgrades more easy to justify (to myself).

    I deviated from my strategy a bit and installed the SSD about six months earlier than I was planning to do so because of a physical barrier. That physical barrier was my new traveling laptop only accepts 7mm height 2.5 inch small form factor devices and the 750GB HHDD that I had planned on installing was 2.5mm to thick which pushed up the SSD installation.

    What will become of the 750GB HHDD? Its being redeployed to help speed up file serving, backups and other functions.

    Will I replace the HHDD’s in my other workstations and laptops now with SSD’s? Across the board no, not yet, however there is one other system that is a prime candidate to maybe upgrade in a month or two (maybe less).

    Will I stick with the Samsung SSD’s or look at other options? I’m keeping my options open and using this as a gauge to test and compare other options in a real world working environment as opposed to a lab bench test simulation. In other words, taking the next step past the lab test and product reviews, gaining comfort and confidence and then trying out with real use activity.

    What will happen in the future as I install more SSD’s and have surplus HHDD’s? Redeployed them of course into file or NAS servers, backup targets that in turn will replace HDD’s that will either get retired, or redeployed to replace older, smaller capacity, higher cost to handle HDD’s used for offsite protection.

    I tried using the software that came with the SSD to do the cloning and should have known better, however wanted to see what the latest version of ghost was like (it was a waste of time to be polite). Instead I used Seagate Discwizard (aka Acronis) which requires at least one Seagate product (source or target) for cloning.

    Cloning from the Seagate HHDD that have been previously cloned from the Hitachi HDD that came with the laptop, was a none issue. However, I wanted to see what would happen if I attached the Samsung SSD to the Seagate Goflex cable and clone directly from the Hitachi HDD, it worked. Hence another reason to have some of the Seagate Goflex cables (USB and eSATA) like the ones I bought at Amazon.com around in your toolbox.

    While I do not have concrete empirical numbers to share, cloning from a HDD to a SSD is shall we say fast, however, what’s really fun to watch is cloning from a HHDD to a SSD using an eSata (GoFlex) connector adapter. The reason I say that it is fun is that you don’t have to sit and wait for hours, it’s not minutes to move 100s of GBs, however you can very much see the progress bar move at a good pace.

    Also, I put the HHDD on an eSata port and try that out as a backup or data dump target if you have the need for speed, capacity and cost effectiveness, yes its fast, has lots of capacity and so forth. Now if Seagate and Synology or EMC Iomega would get their acts together and add support for the HHDD’s in those different unified SMB and SOHO NAS solutions, that would be way cool.

    Will I be racing to put SSD’s in my other laptops or workstations soon? Probably not as there are things in the works and working their way into and through the market place that I wanted to wait for, and thus will wait for now, that is unless a more interesting opportunity pops up.

    More Storage IO momentus HHDD and SSD moments part I

    This is the first of a two part series on my latest experiences with HHDD and SSD’s

    About two years ago I wanted to start installing solid state devices (SSD’s) into my workstations and laptops. Like many others, I found the expensive price for the limited capacity gains of the then generation SSD’s did not make for a good business decision based on my needs. Don’t get me wrong, I have been a huge fan of SSD for decades as an IT user, vendor, analysts, consultant and consumer and still am. In fact I have some SSD’s used for different purposes as well as many Hard Disk Drives (HDD) and Hybrid Hard Disk Drives (HHDD’s). Almost two years ago when I first tested the HHDD’s, I did an first post in this ongoing series and this two-part post is part of that string of experiences observed evolving from HDD’s to HHDD’s to SSD’s

    As a refresher, HHDD’s like the Seagate Momentus XT combine a traditional 7,200 RPM 2.5 inch 500GB or 750GB HDD with an integrated single level cell (SLC) nand flash SSD within the actual device. The SSD in the HHDD’s is part of the HDD’s controller complementing the existing DRAM buffer by adding 4GB (500GB models) or 8GB (750GB models) of fast nand flash SSD cache. This means that no external special controller, adapter, data movement or migration software are required to get the performance boost over a traditional HDD and the capacity above a SSD at an affordable cost. In other words, the HHDD’s bridge the gap between those who need large capacity and some performance increases, without having to spend a lot on a lower capacity SSD.

    However based on my needs or business requirements two years ago I found the justification to get all the extra performance of  SSD not quite there when. Back two years ago my thinking was that it would be about two maybe three years before the right point for a mix of performance, availability (or reliability e.g. duty cycles), capacity and economics aligned.

    Note that this was based on my specific needs and requirements as opposed to my wants or wishes (I wanted SSD back then, however my budget needed to go elsewhere). My requirements and performance needs are probably not the same as yours or others might be. I also wanted to see the incremental technology, product and integration improvements ranging from duty cycle or program/erase cycles (P/E) with newer firmware and flash translation layers (FTLs) among other things. Particularly with multilevel cell (MLC) or enhanced multilevel cell (eMLC) which helps bring the cost down while boosting the capacity, I’m seeing enough to have more confidence in those devices. Note that for the past couple of years I have used single level cell (SLC) nand flash SSD technology in my HHDD’s, the same SSD flash technology that has been found in enterprise class storage.

    While I wanted SSD’s two years ago in my laptops and workstations to improve productivity which involves a lot of content creation in addition to consumption, however as mentioned above, there were barriers. So instead of sitting on the sidelines, waiting for SSD’s to either become lower cost, or more capacity for a given cost, or wishing somebody would send me some free stuff (that may or may not have worked), I took a different route. That route was to try the HHDD’s such as Seagate Momentus XT.

    Disclosure: Seagate sent me my first HHDD for first testing and verifications before buying several more from Amazon.com and installing them in all laptops, workstations and a server (not all servers have the HHDD’s, or at least yet).

    The main reason I went with the HHDD’s two years ago and continue to use them today is to bridge the gap and gain some benefit vs. waiting and wishing and talking about what SSD’s would enable me to do in the future while missing out on productivity enhancements.

    The HHDD’s also appealed to me in that my laptops are space constrained for putting two drives and playing the hybrid configuration game of installing both a small SSD and HDD and migrating data back and forth. Sure I could do that for in the office or carry an extra external device around however been there, done that in the past and want to move away from those types of models where possible.
