How many I/O iops can flash SSD or HDD do?

How many i/o iops can flash ssd or hdd do with vmware?

sddc data infrastructure Storage I/O ssd trends

Updated 2/10/2018

A common question I run across is how many I/O iopsS can flash SSD or HDD storage device or system do or give.

The answer is or should be it depends.

This is the first of a two-part series looking at storage performance, and in context specifically around drive or device (e.g. mediums) characteristics across HDD, HHDD and SSD that can be found in cloud, virtual, and legacy environments. In this first part the focus is around putting some context around drive or device performance with the second part looking at some workload characteristics (e.g. benchmarks).

What about cloud, tape summit resources, storage systems or appliance?

Lets leave those for a different discussion at another time.

Getting started

Part of my interest in tools, metrics that matter, measurements, analyst, forecasting ties back to having been a server, storage and IO performance and capacity planning analyst when I worked in IT. Another aspect ties back to also having been a sys admin as well as business applications developer when on the IT customer side of things. This was followed by switching over to the vendor world involved with among other things competitive positioning, customer design configuration, validation, simulation and benchmarking HDD and SSD based solutions (e.g. life before becoming an analyst and advisory consultant).

Btw, if you happen to be interested in learn more about server, storage and IO performance and capacity planning, check out my first book Resilient Storage Networks (Elsevier) that has a bit of information on it. There is also coverage of metrics and planning in my two other books The Green and Virtual Data Center (CRC Press) and Cloud and Virtual Data Storage Networking (CRC Press). I have some copies of Resilient Storage Networks available at a special reader or viewer rate (essentially shipping and handling). If interested drop me a note and can fill you in on the details.

There are many rules of thumb (RUT) when it comes to metrics that matter such as IOPS, some that are older while others may be guess or measured in different ways. However the answer is that it depends on many things ranging from if a standalone hard disk drive (HDD), Hybrid HDD (HHDD), Solid State Device (SSD) or if attached to a storage system, appliance, or RAID adapter card among others.

Taking a step back, the big picture

Various HDD, HHDD and SSD’s

Server, storage and I/O performance and benchmark fundamentals

Even if just looking at a HDD, there are many variables ranging from the rotational speed or Revolutions Per Minute (RPM), interface including 1.5Gb, 3.0Gb, 6Gb or 12Gb SAS or SATA or 4Gb Fibre Channel. If simply using a RUT or number based on RPM can cause issues particular with 2.5 vs. 3.5 or enterprise and desktop. For example, some current generation 10K 2.5 HDD can deliver the same or better performance than an older generation 3.5 15K. Other drive factors (see this link for HDD fundamentals) including physical size such as 3.5 inch or 2.5 inch small form factor (SFF), enterprise or desktop or consumer, amount of drive level cache (DRAM). Space capacity of a drive can also have an impact such as if all or just a portion of a large or small capacity devices is used. Not to mention what the drive is attached to ranging from in internal SAS or SATA drive bay, USB port, or a HBA or RAID adapter card or in a storage system.

disk iops
HDD fundamentals

How about benchmark and performance for marketing or comparison tricks including delayed, deferred or asynchronous writes vs. synchronous or actually committed data to devices? Lets not forget about short stroking (only using a portion of a drive for better IOP’s) or even long stroking (to get better bandwidth leveraging spiral transfers) among others.

Almost forgot, there are also thick, standard, thin and ultra thin drives in 2.5 and 3.5 inch form factors. What’s the difference? The number of platters and read write heads. Look at the following image showing various thickness 2.5 inch drives that have various numbers of platters to increase space capacity in a given density. Want to take a wild guess as to which one has the most space capacity in a given footprint? Also want to guess which type I use for removable disk based archives along with for onsite disk based backup targets (compliments my offsite cloud backups)?

types of disks
Thick, thin and ultra thin devices

Beyond physical and configuration items, then there are logical configuration including the type of workload, large or small IOPS, random, sequential, reads, writes or mixed (various random, sequential, read, write, large and small IO). Other considerations include file system or raw device, number of workers or concurrent IO threads, size of the target storage space area to decide impact of any locality of reference or buffering. Some other items include how long the test or workload simulation ran for, was the device new or worn in before use among other items.

Tools and the performance toolbox

Then there are the various tools for generating IO’s or workloads along with recording metrics such as reads, writes, response time and other information. Some examples (mix of free or for fee) include Bonnie, Iometer, Iorate, IOzone, Vdbench, TPC, SPC, Microsoft ESRP, SPEC and netmist, Swifttest, Vmark, DVDstore and PCmark 7 among many others. Some are focused just on the storage system and IO path while others are application specific thus exercising servers, storage and IO paths.

performance tools
Server, storage and IO performance toolbox

Having used Iometer since the late 90s, it has its place and is popular given its ease of use. Iometer is also long in the tooth and has its limits including not much if any new development, never the less, I have it in the toolbox. I also have Futremark PCmark 7 (full version) which turns out has some interesting abilities to do more than exercise an entire Windows PC. For example PCmark can use a secondary drive for doing IO to.

PCmark can be handy for spinning up with VMware (or other tools) lots of virtual Windows systems pointing to a NAS or other shared storage device doing real world type activity. Something that could be handy for testing or stressing virtual desktop infrastructures (VDI) along with other storage systems, servers and solutions. I also have Vdbench among others tools in the toolbox including Iorate which was used to drive the workloads shown below.

What I look for in a tool are how extensible are the scripting capabilities to define various workloads along with capabilities of the test engine. A nice GUI is handy which makes Iometer popular and yes there are script capabilities with Iometer. That is also where Iometer is long in the tooth compared to some of the newer generation of tools that have more emphasis on extensibility vs. ease of use interfaces. This also assumes knowing what workloads to generate vs. simply kicking off some IOPs using default settings to see what happens.

Another handy tool is for recording what’s going on with a running system including IO’s, reads, writes, bandwidth or transfers, random and sequential among other things. This is where when needed I turn to something like HiMon from HyperIO, if you have not tried it, get in touch with Tom West over at HyperIO and tell him StorageIO sent you to get a demo or trial. HiMon is what I used for doing start, stop and boot among other testing being able to see IO’s at the Windows file system level (or below) including very early in the boot or shutdown phase.

Here is a link to some other things I did awhile back with HiMon to profile some Windows and VDI activity test profiling.

What’s the best tool or benchmark or workload generator?

The one that meets your needs, usually your applications or something as close as possible to it.

FusionIO (FIO) SSD vendor CEO out in a flash, whats up with that?

Storage I/O trends

FusionIO (FIO) who recently bought Nexgen to expand their reach from just a server centric to a more broad flash focus has seen their CEO and founder David Flynn race out the door. Not surprisingly, wall street who does not like to be surprised were surprised just a week or two after the most recent earning announcements reacted with a sell off of the FIO stock.

Here is the conundrum, those who were or are fans of Flynn, FIO and their approach along with server centric in your face approach may not be happy with this move.

On the other hand, those were not fans of Flynn, FIO and their approach of getting in your face of having others do so if you did not fall into their ranks may be happy with this move.

One question is was Flynn shown the door and left before it could hit his backside on the way out, or, did he see something and pulled the rip cord on his golden parachute, or some other or combination?

With the recent Nexgen acquisition which could be seen as a move by FIO (and their board of directors) to make more attractive either for an acquisition. Or, to transition from a server-side centric approach to a broader focus.

If the former, perhaps Flynn sees or saw the writing on the wall on who those suitors might or would be and decided to take his money now and run joining the serial entrepreneur ranks now.

Otoh, perhaps Flynn was just too focused with a singular focus and passion on the server space thus not able or interested in transitioning to a broader focus, which might also have involved eating a bit of crow. By eating a bit of crow, I mean given some of the in your face and it’s the FIO way or the highway approach of server only flash.

With Nexgen to be successful that would involve aligning more with the larger vendors and other startups who offer broader portfolios, something that was targeted and mud or fud thrown at by FIO, something that some CEOs or others can have challenges with. It should also be noted that FIO has brought in new employees with experience in broader marketers, not to mention industry veterans like John Spiers of Nexgen.

Candidly, I am not sure which of the above is the scenario, however, for those involved with FIO as employees, partners, customers and shareholders I hope some clarity arrives soon for them. Whether that clarity is via an acquisition (who is one of many questions), or a launching as FIO 2.0 or something similar with a focus on bring more capabilities to customers, increasing their touch points selling more products, hardware, software as opposed to leaving those for others (e.g. their competitors).

EMC ViPR software defined object storage part III

Storage I/O trends

This is part III in a series of posts pertaining to EMC ViPR software defined storage and object storage. You can read part I here and part II here.

EMCworld

More on the object opportunity

Other object access includes OpenStack storage part Swift, AWS S3 HTTP and REST API access. This also includes ViPR supporting EMC Atmos, VNX and Isilon arrays as southbound persistent storage in addition.

object storage
Object (and cloud) storage access example

EMC is claiming that over 250 VNX systems can be abstracted to support scaling with stability (performance, availability, capacity, economics) using ViPR. Third party storage will be supported along with software such as OpenStack Swift, Ceph and others running on commodity hardware. Note that EMC has some history with object storage and access including Centera and Atmos. Visit the micro site I have setup called www.objectstoragecenter.com and watch for more content to be updated and added there.

More on the ViPR control plane and controller

ViPR differs from some others in that it does not sit in the data path all the time (e.g. between application servers and storage systems or cloud services) to cut potential for bottlenecks.

ViPR architecture

Organizations that can use ViPR include enterprise, SMB, CSP or MSP and hosting sites. ViPR can be used in a control mode to leverage underlying storage systems, appliances and services intelligence and functionality. This means ViPR can be used to complement as oppose to treat southbound or target storage systems and services as dumb disks or JBOD.

On the other hand, ViPR will also have a suite of data services such as snapshot, replication, data migration, movement, tiering to add value for when those do not exist. Customers will be free to choose how they want to use and deploy ViPR. For example leveraging underlying storage functionality (e.g. lightweight model), or in a more familiar storage virtualization model heavy lifting model. In the heavy lifting model more work is done by the virtualization or abstraction software to create an added value, however can be a concern for bottlenecks depending how deployed.

Service categories

Software defined, storage hypervisor, virtual storage or storage virtualization?

Most storage virtualization, storage hypervisors and virtual storage solutions that are hardware or software based (e.g. software defined) implemented what is referred to as in band. With in band the storage virtualization software or hardware sits between the applications (northbound) and storage systems or services (southbound).

While this approach can be easier to carry out along with add value add services, it can also introduce scaling bottlenecks depending on implementations. Examples of in band storage virtualization includes Actifio, DataCore, EMC VMAX with third-party storage, HDS with third-party storage, IBM SVC (and their V7000 Storwize storage system based on it) and NetApp Vseries among others. An advantage of in band approaches is that there should not need to be any host or server-side software requirements and SAN transparency.

There is another approach called out-of-band that has been tried. However pure out-of-band requires a management system along with agents, drivers, shims, plugins or other software resident on host application servers.

fast path control path
Example of generic fast path control path model

ViPR takes a different approach, one that was seen a few years ago with EMC Invista called fast path, control path that for the most part stays out of the data path. While this is like out-of-band, there should not be a need for any host server-side (e.g. northbound) software. By being a fast path control path, the virtualization or abstraction and management functions stay out of the way for data being moved or work being done.

Hmm, kind of like how management should be, there to help when needed, out-of-the-way not causing overhead other times ;).

Is EMC the first (even with Invista) to leverage fast path control path?

Actually up until about a year or so ago, or shortly after HP acquired 3PAR they had a solution called Storage Virtualization Services Platform (SVPS) that was OEMd from LSI (e.g. StorAge). Unfortunately, HP decided to retire that as opposed to extend its capabilities for file and object access (northbound) as well as different southbound targets or destination services.

Whats this northbound and southbound stuff?

Simply put, think in terms of a vertical stack with host servers (PMs or VMs) on the top with applications (and hypervisors or other tools such as databases) on top of them (e.g. north).

software defined storage
Northbound servers, southbound storage systems and cloud services

Think of storage systems, appliances, cloud services or other target destinations on the bottom (or south). ViPR sits in between providing storage services and management to the northbound servers leveraging the southbound storage.

What host servers can VIPR support for serving storage?

VIPR is being designed to be server agnostic (e.g. virtual or physical), along with operating system agnostic. In addition VIPR is being positioned as capable of serving northbound (e.g. up to application servers) block, file or object as well as accessing southbound (e.g. targets) block, file and object storage systems, file systems or services.

Note that a difference between earlier similar solutions from EMC have been either block based (e.g. Invista, VPLEX, VMAX with third-party storage), or file based. Also note that this means VIPR is not just for VMware or virtual server environments and that it can exist in legacy, virtual or cloud environments.

ViPR image

Likewise VIPR is intended to be application agnostic supporting little data, big data, very big data ( VBD) along with Hadoop or other specialized processing. Note that while VIPR will support HDFS in addition to NFS and CIFS file based access, Hadoop will not be running on or in the VIPR controllers as that would live or run elsewhere.

How will VIPR be deployed and licensed?

EMC has indicated that the VIPR controller will be delivered as software that installs into a virtual appliance (e.g. VMware) running as a virtual machine (VM) guest. It is not clear when support will exist for other hypervisors (e.g. Microsoft Hyper-V, Citrix/XEN, KVM or if VMware vSphere with vCenter or simply on ESXi free version). As of the announcement pre briefing, EMC had not yet finalized pricing and licensing details. General availability is expected in the second half of calendar 2013.

Keep in mind that the VIPR controller (software) runs as a VM that can be hosted on a clustered hypervisor for HA. In addition, multiple VIPR controllers can exist in a cluster to further enhance HA.

Some questions to be addressed among others include:

  • How and where are IOs intercepted?
  • Who can have access to the APIs, what is the process, is there a developers program, SDK along with resources?
  • What network topologies are supported local and remote?
  • What happens when JBOD is used and no advanced data services exist?
  • What are the characteristics of the object access functionality?
  • What if any specific switches or data path devices and tools are needed?
  • How does a host server know to talk with its target and ViPR controller know when to intercept for handling?
  • Will SNIA CDMI be added and when as part of the object access and data services capabilities?
  • Are programmatic bindings available for the object access along with support for other APIs including IOS?
  • What are the performance characteristics including latency under load as well as during a failure or fault scenario?
  • How will EMC place Vplex and its caching model on a local and wide area basis vs. ViPR or will we see those two create some work together, if so, what will that be?

Bottom line (for now):

Good move for EMC, now let us see how they execute including driving adoption of their open APIs, something they have had success in the past with Centera and other solutions. Likewise, let us see what other storage vendors become supported or add support along with how pricing and licensing are rolled out. EMC will also have to articulate when and where to use ViPR vs. VPLEX along with other storage systems or management tools.

EMC ViPR software defined object storage part II

Storage I/O trends

This is part II in a series of posts pertaining to EMC ViPR software defined storage and object storage. You can read part I here and part III here.

EMCworld

Some questions and discussion topics pertaining to ViPR:

Whom is ViPR for?

Organizations that need to scale with stability across EMC, third-party or open storage software stacks and commodity hardware. This applies to large and small enterprise, cloud service providers, managed service providers, virtual and cloud environments/

What this means for EMC hardware/platform/systems?

They can continue to be used as is, or work with ViPR or other deployment modes.

Does this mean EMC storage systems are nearing their end of life?

IMHO for the most part not yet, granted there will be some scenarios where new products will be used vs. others, or existing ones used in new ways for different things.

As has been the case for years if not decades, some products will survive, continue to evolve and find new roles, kind of like different data storage mediums (e.g. ssd, disk, tape, etc).

How does ViPR work?

ViPR functions as a control plane across the data and storage infrastructure supporting both north and southbound. northbound refers to use from or up to application servers (physical machines PM and virtual machines VMs). southbound refers target or destination storage systems. Storage systems can be traditional EMC or third-party (NetApp mentioned as part of first release), appliances, just a bunch of disks (JBOD) or cloud services.

Some general features and functions:

  • Provisioning and allocation (with automation)
  • Data and storage migration or tiering
  • Leverage scripts, templates and workbooks
  • Support service categories and catalogs
  • Discovery, registration of storage systems
  • Create of storage resource pools for host systems
  • Metering, measuring, reporting, charge or show back
  • Alerts, alarms and notification
  • Self-service portal for access and provisioning

ViPR data plane (adding data services and value when needed)

Another part is the data plane for implementing data services and access. For block and file when not needed, ViPR steps out-of-the-way leveraging the underlying storage systems or services.

object storage
Object storage access

When needed, the ViPR data plane can step in to add added services and functionality along with support object based access for little data and big data. For example, Hadoop Distributed File System (HDFS) services can support northbound analytic software applications running on servers accessing storage managed by ViPR.

Continue reading in part III of this series here including how ViPR works, who it is for and more analysis.

EMC ViPR virtual physical object and software defined storage (SDS)

Storage I/O trends

Introducing EMC ViPR

This is the first in a three part series, read part II here, and part III here.

During the recent EMCworld event in Las Vegas among other things, EMC announced ViPR (read announcement here) . Note that this ViPR is not the same EMC Viper project from a few years ago that was focused on data footprint reduction (DFR) including dedupe. ViPR has been in the works for a couple of years taking a step back rethinking how storage is can be used going forward.

EMCworld

ViPR is not a technology creation developed in a vacuum instead includes customer feedback, wants and needs. Its core themes are extensible, open and scalable.

EMCworld

On the other hand, ViPR addresses plenty of buzzword bingo themes including:

  • Agility, flexibility, multi-tenancy, orchestration
  • Virtual appliance and control plane
  • Data services and storage management
  • IT as a Service (ITaaS) and Infrastructure as a Service (IaaS)
  • Scaling with stability without compromise
  • Software defined storage
  • Public, private, hybrid cloud
  • Big data and little data
  • Block, file and object storage
  • Control plane and data plane
  • Storage hypervisor, virtualization and virtual storage
  • Heterogeneous (third-party) storage support
  • Open API and automation
  • Self-service portals, service catalogs

Buzzword bingo

Note that this is essentially announcing the ViPR product and program initiative with general availability slated for second half of 2013.

What is ViPR addressing?

IT and data infrastructure (server, storage, IO and networking hardware, software) challenges for traditional, virtual and cloud environments.

  • Data growth, after all, there is no such thing as an information recession with more data being generated, moved, processed, stored and retained for longer periods of time. Then again, people and data are both getting larger and living longer, for both little data and big data along with very big data.

  • Overhead and complexities associated with managing and using an expanding, homogenous (same vendor, perhaps different products) or heterogeneous (different vendors and products) data infrastructure across cloud, virtual and physical, legacy and emerging. This includes add, changes or moves, updates and upgrades, retirement and replacement along with disposition, not to mention protecting data in an expanding footprint.

    • road to cloud

  • Operations and service management, fault and alarm notification, resolution and remediation, rapid provisioning, removing complexity and cost of doing things vs. simply cutting cost and compromising service.

EMC ViPR

What is this software defined storage stuff?

There is the buzzword aspect, and then there is the solution and business opportunity.

First the buzzword aspect and bandwagon:

  • Software defined marketing (SDM) Leveraging software defined buzzwords.
  • Software defined data centers (SDDC) Leveraging software to derive more value from hardware while enabling agility, flexibility, and scalability and removing complexity. Think the Cloud and Virtual Data Center models including those from VMware among others.
  • Software defined networking (SDN) Rather than explain, simply look at Nicira that VMware bought in 2012.
  • Software defined storage (SDS) Storage software that is independent of any specific hardware, which might be a bit broad, however it is also narrower than saying anything involving software.
  • Software defined BS (SDBS) Something that usually happens as a result when marketers and others jump on a bandwagon, in this case software defined marketing.

Note that not everything involved with software defined is BS, only some of the marketing spins and overuse. The downside to the software defined marketing and SDBS is the usual reaction of skepticism, cynicism and dismissal, so let us leave the software defined discussion here for now.

software defined storage

An example of software defined storage can be storage virtualization, virtual storage and storage hypervisors that are hardware independent. Note that when I say hardware independent, that also means being able to support different vendors systems. Now if you want to have some fun with the software defined storage diehards or purist, tell them that all hardware needs software and all software needs hardware, even if virtual. Further hardware is defined by its software, however lets leave sleeping dogs lay where they rest (at least for now ;)).

Storage hypervisors were a 2012 popular buzzword bingo topic with plenty of industry adoption and some customer deployment. While 2012 saw plenty of SDM buzz including SDC, SDN 2013 is already seeing an increase including software defined servers, and software defined storage.

Regardless of what you view of software defined storage, storage hypervisor, storage virtualization and virtual storage is, the primary focus and goal should be addressing business and application needs. Unfortunately, some of the discussions or debates about what is or is not software defined and related themes lose focus of what should be the core goal of enabling business and applications.

Spring SNW 2013, Storage Networking World Recap

Storage I/O trends

A couple of weeks ago I attended the spring 2013 Storage Networking World (SNW) in Orlando Florida. Talking with SNIA Chairman Wayne Adams and SNIA Director Leo Legar this was the 28th edition of the US SNW (two shows a year), plus the international ones. While I have not been to all 28 of the US SNWs, I have been to a couple of dozen SNWs in the US, Europe and Brazil going back to around 2001 as an attendee, main stage as well as breakout, and tutorial presenter (see here and here).

SNW image

For the spring 2013 SNW I was there for a mix of meetings, analyst briefings, attending the expo, doing some podcasts (see below), meeting with IT professionals (e.g. customers), VARs, vendors along with presenting three sessions (you can download them and others backup, restore, BC, DR and archiving).

Some of the buzz and themes heard included big data was a little topic at the event, while cloud was in the conversations, dedupe and data footprint reduction (DFR) do matter for some people and applications. However also a common theme with customers including Media and Entertainment (M&E) is that not everything can be duped thus other DFR approaches are needed.

There was some hype in and around hybrid storage along with storage hypervisors, which was also an entertaining panel discussion with HDS (Claus Mikkelsen aka @YoClaus), Datacore, IBM and Virstro.

The theme of that discussion seemed for the most part to gravitate towards realities of storage virtualization and less about the hypervisor hype. Some software defined marketing hype I heard is that it is impossible to spend more than a million dollars on a server today. I guess with the applicable caveats, qualifiers and context that could be true, however I also know some vendors and customers that would say otherwise.

Lunch
Lunchtime at SNW Spring 2013

Not surprisingly, there was an increase in vendors wanting to jump on the software defined and object storage bandwagons; however, customers tended to be curious at best, confused or concerned otherwise. Speaking of object storage, check out this podcast discussion with Cleversafe customer Justin Stottlemyer of Shutterfly and his 80PB environment.

In addition to Cleversafe, heard from Astute (if you need fast iSCSI storage check them out), Avere has a new NAS for dummies book out, Exablox a storage system startup with emphasis on scalability, ease of use and NAS access and hybrid storage Tegile. Also, check out SwifTest for generating application workloads and measurement that had their customer Go Daddy presenting at the event. A couple of others to keep an eye on include Raxco with their thin provision storage reclamation tool, and Infinio with their NAS acceleration for VMware software tools among others.

backup, restore, BC, DR and archiving

Here are the three presentations that I did while at the event:

Analyst Perspective: Increase Your Return on Innovation (The New ROI) With Data Management and Dedupe
There is no such thing as an information recession with more data to move, process and store, however there are economic challenges. Likewise, people and data are living longer and getting larger which requires leveraging data footprint reduction (DFR) techniques on a broader focus. It is time to move upstream finding and fixing things at the source to reduce the downstream impact of expanding data footprints, enabling more to be done with what you have.

Analyst Perspective: Metrics that Matter – Meritage of Data Management and Data Protection
Not everything in the data center or information factory is the same. This session recaps and builds off the morning increase your ROI with data footprint and data management session while setting the stage for the rethinking data protection (backup, BC and DR). Are you maximizing the return on innovation in how using new tools and technology in new ways, vs. using new tools in old ways? Also discussed performance capacity planning, forecasting analysis in cloud, virtual and physical environments. Without metrics that matter, you are flying blind, or perhaps missing opportunities to further drive your return on innovation and return on investment.

Analyst Perspective: Time to Rethink Data Protection Including BC and DR
When it comes to today’s data centers and information factories including physical, virtual and cloud, everything is not the same, so why treat business continuance (BC), disaster recovery (DR) and data protection in general the same? Simply using new tools, technologies and techniques in the same old ways is no longer a viable option. Since there is no such thing as a data or information recession, yet there are economic and budget challenges, along with new or changing threat risks, now is the time to review data protection including BC and DR including using new technologies in new ways.

Storage I/O trends

What this all means?

While busy, I liked this edition of SNW USA in that it had a great agenda with diversity and balance of speaker sessions (some tutorials, some vendors, some IT customers, and some analysts) vs. too many of one specific area.

In addition to the agenda and session length, the venue was good, big enough, however not spread out so much to cause loss of the buzz and energy of the event.

This SNW had some similar buzz or energy as early versions granted without the hype and fanfare of a startup industry or focus area (that would be some of the other events today)

Should SNW go to a once a year event?

While it would be nice to have a twice a year venue for convenience, practicality and budgets say once would be enough given all the other conferences and venues on the agenda (or that could be).

The next SNW USA will be October 15 to 17 2013 in Long Beach California, and Europe in Frankfurt Germany October 29-30 2013.

Thanks again to all the attendees, participants, vendor exhibitors, event organizers and SNIA, SNW/Computerworld staffs for another great event.

Storage I/O cloud virtual and big data perspectives

In this episode from SNW Fall 2012 in Santa Clara, I am joined by my co-host Bruce Ravid (@BruceRave) of Ravid and Associates as we catch up with long time storage industry veteran Claus Mikkelsen (@YoClaus) and HDS Chief Scientist.

Bruce and Claus meet for the first time having been around and probably passed each other in the halls at various events, hence, its a small world, however there is always opportunity to meet somebody new. We also chat about SNW past and present, data storage, technologies, networking with people, travel and of course with Claus, touch on wine.

Note that Claus and me were apart of a consortium of people that collaborated on the original book The Resilient Enterprise released in spring of 2012 published by Veritas. Ok, nuff said.

HP Moonshot 1500 software defined capable compute servers

Storage I/O cloud virtual and big data perspectives

Riding the current software defined data center (SDC) wave being led by the likes of VMware and software defined networking (SDN) also championed by VMware via their acquisition of Nicira last year, Software Defined Marketing (SDM) is in full force. HP being a player in providing the core building blocks for traditional little data and big data, along with physical, virtual, converged, cloud and software defined has announced a new compute, processor or server platform called the Moonshot 1500.

HP Moonshot software defined server image

Software defined marketing aside, there are some real and interesting things from a technology standpoint that HP is doing with the Moonshot 1500 along with other vendors who are offering micro server based solutions.

First, for those who see server (processor and compute) improvements as being more and faster cores (and threads) per socket, along with extra memory, not to mention 10GbE or 40GbE networking and PCIe expansion or IO connectivity, hang on to your hats.

HP Moonshot software defined server image individual server blade

Moonshot is in the model of the micro servers or micro blades such as what HP has offered in the past along with the likes of Dell and Sea Micro (now part of AMD). The micro servers are almost the opposite of the configuration found on regular servers or blades where the focus is putting more ability on a motherboard or blade.

With micro servers the approach support those applications and environments that do not need lots of CPU processing capability, large amount of storage or IO or memory. These include some web hosting or cloud application environments that can leverage more smaller, lower power, less performance or resource intensive platforms. For example big data (or little data) applications whose software or tools benefit from many low-cost, low power, and lower performance with distributed, clustered, grid, RAIN or ring based architectures can benefit from this type of solution.

HP Moonshot software defined server image and components

What is the Moonshot 1500 system?

  • 4.3U high rack mount chassis that holds up to 45 micro servers
  • Each hot-swap micro server is its own self-contained module similar to blade server
  • Server modules install vertically from the top into the chassis similar to some high-density storage enclosures
  • Compute or processors are Intel Atom S1260 2.0GHz based processors with 1 MB of cache memory
  • Single S0-DIMM slot (unbuffered ECC at 1333 MHz) supports 8GB (1 x 8GB DIMM) DRAM
  • Each server module has a single 2.5″ SATA 200GB SSD, 500GB or 1TB HDD onboard
  • A dual port Broadcom 5720 1 Gb Ethernet LAn per server module that connects to chassis switches
  • Marvel 9125 storage controller integrated onboard each server module
  • Chassis and enclosure management along with ACPI 2.0b, SMBIOS 2.6.1 and PXE support
  • A pair of Ethernet switches each give up to six x 10GbE uplinks for the Moonshot chassis
  • Dual RJ-45 connectors for iLO chassis management are also included
  • Status LEDs on the front of each chassis providers status of the servers and network switches
  • Support for Canonical Ubuntu 12.04, RHEL 6.4, SUSE Linux LES 11 SP2

Storage I/O cloud virtual and big data perspectives

Notice a common theme with moonshot along with other micro server-based systems and architectures?

If not, it is simple, I mean literally simple and flexible is the value proposition.

Simple is the theme (with software defined for marketing) along with low-cost, lower energy power demand, lower performance, less of what is not needed to remove cost.

Granted not all applications will be a good fit for micro servers (excuse me, software defined servers) as some will need the more robust resources of traditional servers. With solutions such as HP Moonshot, system architects and designers have more options available to them as to what resources or solution options to use. For example, a cloud or object storage system based solutions that does not need a lot of processing performance per node or memory, and a low amount of storage per node might find this as an interesting option for mid to entry-level needs.

Will HP release a version of their Lefthand or IBRIX (both since renamed) based storage management software on these systems for some market or application needs?

How about deploying NoSQL type tools including Cassandra or Mongo, how about CloudStack, OpenStack Swift, Basho Riak (or Riak CS) or other software including object storage, on these types of solutions, or web servers and other applications that do not need the fastest processors or most memory per node?

Thus micro server-based solutions such as Moonshot enable return on innovation (the new ROI) by enabling customers to leverage the right tool (e.g. hard product) to create their soft product allowing their users or customers to in turn innovate in a cost-effective way.

Will the Moonshot servers be the software defined turnaround for HP, click here to see what Bloomberg has to say, or Forbes here.

Learn more about Moonshot servers at HP here, here or data sheets found here.

Btw, HP claims that this is the industries first software defined server, hmm.

Ok, nuff said (for now).
