Overview Review of Microsoft ReFS (Reliable File System) and resource links

server storage I/O trends

This is an overview review of Microsoft ReFS (Resilient File System) along with some resource links. ReFS is part of some Windows operating system platforms including Server 2016.

Some context here is that review can mean an in-depth deep dive product or technology review, while another meaning is to simply to refresh what you may already know about ReFS. For this post, the focus is on the latter, that is a bit of overview that also functions as a refresh review of what you may already know. However click here to see how ReFS and NTFS compare.

Click here to read more about Windows Server 2016, Storage Spaces Direct (S2D), Storage Replica (SR) and other related topics (or click on the image below).

What Is Microsoft ReFS and Why It Matters

Microsoft ReFS (Resilient File System) is part of Windows Servers 2012, 2012 R2, 2016 as well as Windows 8.1 and 10 platforms as an alternative to NTFS file system. ReFS is designed not only for resiliency, also for scaling volumes beyond 256 TBytes (NTFS) to 4.7 Zettabytes (ZB). Note files size for both NTFS and ReFS is 18 Exabytes (EB). Click here to view various ReFS and NTFS data services, feature functionality along with limits. Part of being resilient means that ReFS is able to provide more data integrity protection to guard against logical data corruption.

Note while ReFS is the future for Windows-based platforms, NTFS is not going away anytime soon, after all, FAT (File Allocation Table) volumes are still supported after how many decades of being around? ReFS has been around for several years having existed in earlier WIndows operating systems as an option, however with Server 2016, its status is promoted to a more prominent role with more features, data services and functionality.

ReFS data services, features and functionality include:

  • Resiliency – Automatic detection and online repair of data corruption issues
  • Online repair – Isolate faults to localized area of data corruption for repair enabling volumes to stay online
  • Storage Spaces integration – Leverage mirror or parity spaces for automatic detect and repair via alternate data copies. Note that with Windows Server 2016 Microsoft also has introduced Storage Spaces Direct (S2D).
  • Data salvage – Should a volume become corrupt with no alternate copy (you should still have a backup), ReFS removes corrupt data from name space on a live volume. This capability enables surviving data to stay accessible while isolating the fault to the corrupted or damaged data.
  • Integrity streams – Checksums for metadata and optionally file data that enable ReFS to detect corruptions in a reliable way.
  • Proactive error correction – Besides validating data before reads and writes, ReFS also has a background scrubber data integrity check of volumes. This capability enables ReFS to proactively detect latent or silent data corruption so that corrective repair of damaged data can occur.
  • Real-time tiering – When combined with S2D maximizes performance and space capacity across performance and capacity tiers using NVMe, flash SSD and HDDs devices. Writes occur to the performance tier, with large chunks de-staged to capacity tier. Read acceleration enabled via cache. Can support all flash (e.g. performance NVMe and capacity TLC or other flash SSD) as well as hybrid mix of HDD and SSD configurations.
  • Block cloning for dynamic workloads including server virtualization such as accelerating checkpoint merge operations.
  • Sparse VDL (Valid Data Length) improves virtual machine (VM) operations reducing time needed to create fixed size VHDs from 10s of minutes to seconds.
  • Variable storage allocation cluster size of 4KB (for most environments) and 64KB (for environments with larger sequential file processing needs).

ReFS Deployment Options

Microsoft ReFS deployment options include:

  • Basic disk (HDD, and SSD) – Leverage applications or other resiliency and protection solutions.
  • SAS drive enclosures with storage spaces provides more data protection including availability as well as integrity and accessibility. Leverages classic storage spaces mirroring and parity protection for increased resiliency and availability.
  • Storage Spaces Direct (S2D) – Increased scalability, real-time tiering and cache server storage I/O performance (effectiveness) and capacity (efficiency) optimization. For increased resiliency adds block clone and sparse Valid Data Length (VDL) to boost VHDX file performance operations (create, merge, expand). For resiliency, built-in checksums, online repair as well as leverage alternate data copies combined with S2D to detect as well as correct both metadata as well as primary data corruption issues. Optimized for large-scale and virtualized application workloads.

What This All Means

Now is as good of time as any to refresh (or enhance) your knowledge of ReFS and its current capabilities particular if you are involved with Microsoft environments. On the other hand, if you are not involved with Microsoft, take a few moments to update your insight and awareness of ReFS, storage spaces, S2D and other related capabilities including Windows Servers converged (desegregated) and hyper-converged (aggregated) options to avoid working off of or with stale data.

Ok, nuff said, for now…

    Industry Activity Trends

    Recent Industry Activates and Trends

    EMC is now Dell EMC – What this means is that EMC is no longer a publicly traded company instead now being privately held under the Dell Technologies umbrella. In case you did not know or had forgotten, one of the principal owners of Dell Technologies is Michael Dell aka the founder of Dell Computers which itself went private a few years ago. Read more in this Server StoageIOblog update post.

    While Michael Dell and Dell Technologies continues to expand by acquiring companies (granted also shedding some assets to support that growth), HP Enterprise (HPE) is taking a different approach. Similar to Dell, HPE has been offloading some of its divisions and assets since its split into two separate companies about a year ago.

    More recently HPE has announced it is selling off some of its software assets to which follows other deals where HPE created a new partnership with CSC to offload or park some of its services assets. What’s not clear is HPE CEO Meg Whitman leveraging the trend that some Private Equity (PE) firms are interested in acquiring under performing companies or assets to prepare them as part of a pivot to profit scenario, or something else?

    • HPE selling off business units including software group here, here, here and here
    • HPE looking to boost its HPC and super compute business with $275B acquisition of SGI
    • Announced new shared storage for SMB and mid-size environments including for sub $10K price points. These include HPE StoreVirtual 3200 and HPE MSA 2042.
    • HPE and Dropbox partnership
    • Various other HPE news and updates

    Hyper-Converged Infrastructure (HCI) startup vendor Nutanix finally IPO (NTNX) after a not so consolidated IPO cycle. Prior to the IPO NTNX acquired other startup Pernix (VMware cache software solution) and calmio to beef up their product portfolio. Congratulations to NTNX and best wishes, hopefully the public markets will provide risk vs. reward, on the other hand, now being public, the spotlight will be on them.

AD is critical to organizational operations providing control and secure access to data, networks, servers, storage and more from physical, virtual and cloud (public and hybrid). But over time, organizations along with their associated IT infrastructures have evolved due to mergers, acquisitions, restructuring and general growth. As a result, yesterday’s AD deployments may look like they did in the past while using new technology (e.g. in old ways). Now is the time to start planning for how you will optimize your AD environment using new tools and technologies such as those in Windows Server 2016 and AD in new ways. Optimizing AD means having a new design, performing cleanup and restructuring prior to migration vs. simply moving what you have. Join us for this interactive webinar to begin planning your journey to Windows Server 2016 and a new optimized AD deployment that is flexible, scalable and elastic, and enables resilient infrastructures. You will learn:

    • What’s new in Windows Server 2016 and how it impacts your AD
    • Why an optimized AD is critical for IT environments moving forward
    • How to gain insight into your current AD environment
    • AD restructuring planning considerations

    Here is a Microsoft TechNet post that goes into more detail of what is new in WIndows Server 2016.

    Free ebook: Introducing Windows Server 2016 Technical Preview (Via Microsoft Press)

    Check out the above free ebook, after looking through it, I recommend adding it to your bookshelf. There are lots of good intro and overview material for Windows Server 2016 to get you up to speed quickly, or as a refresh.

    Storage Spaces Direct (S2D) CI and HCI

    Storage Spaces Direct (S2D) builds on Storage Spaces that appeared in earlier Windows and Windows Server editions. Some of the major changes and enhancements include ability to leverage local direct attached storage (DAS) such as internal (or external) dedicated NVMe, SAS and SATA HDDs as well as flash SSDs that used for creating software defined storage for various scenarios.

    Scenarios include converged infrastructure (CI) disaggregated as well as aggregated hyper-converged infrastructure (HCI) for Hyper-V among other workloads. Windows Server 2016 S2D nodes communicate (from a storage perspective) via a software storage bus. Data Protection and availability is enabled between S2D nodes via Storage Replica (SR) that can do software based synchronous and asynchronous replication.

    What This All Means

    While Microsoft Windows Server recently celebrated its 20th birthday (or anniversary), a lot has changed as well as evolved. This includes Windows Servers 2016 supporting new deployment and consumption models (e.g. lightweight Nano, full data center with desktop interface, on-premises, bare metal, virtualized (Hyper-V, VMware, etc) as well as cloud). Besides how consumed and configured, which can also be for CI and HCI modes, Windows Server 2016 along with Hyper-V extend the virtualization and container capabilities into non-Microsoft environments specifically around Linux and Docker. Not only are the support for those environments and platforms enhanced, so to are the management capabilities and interfaces from Powershell to Bash Linux shell being part of WIndows 10 and Server 2016.

    What this all means is that if you have not looked at Windows Server in some time, its time you do, even if you are not a WIndows or Microsoft fan, you will want to know what it is that has been updated (perhaps even update your fud if that is the case) to stay current. Get your hands on the bits and try Windows Server 2016 on a bare metal server, or as a VM guest, or via cloud including Azure, or simply leverage the above resources to learn more and stay informed.

    The Value of Infrastructure Insight – Enabling Informed Decision Making

    The Value of Infrastructure Insight – Enabling Informed Decision Making

    server storage I/O trends

    Join me and Virtual Instruments CTO John Gentry on October 27, 2016 for a free webinar (registration required) titled The Value of Infrastructure Insight – Enabling Informed Decision Making with Virtual Instruments. In this webinar, John and me will discuss the value of data center infrastructure insight both as a technology as well as a business and IT imperative.

    Software Defined Data Infrastructure
    Various Infrastructures – Business, Information, Data and Physical (or cloud)

    Leveraging infrastructure performance analytics is key to assuring the performance, availability and cost-effectiveness of your infrastructure, especially as you transform to a hybrid data center over the coming years. By utilizing real-time and historical infrastructure insight from your servers, storage and networking, you can avoid flying blind and give situational awareness for proactive decision-making. The result is faster problem resolution, problem avoidance, higher utilization and the elimination of performance slowdowns and outages.

    View the companion Server StorageIO Industry Trends Report available here (free, no registration required) at the Virtual Instruments web page resource center.

    xxxx

    The above Server StorageIO Industry Trends Perspective Report (click here to download PDF) looks at the value of data center infrastructure insight both as a technology as well as a business productivity enabler. Besides productivity, having insight into how data infrastructure resources (servers, storage, networks, system software) are used, enables informed analysis, troubleshooting, planning, forecasting as well as cost-effective decision-making.

    In other words, data center infrastructure insight, based on infrastructure performance analytics, enables you to avoid flying blind, having situational awareness for proactive Information Technology (IT) management. Your return on innovation is increased, and leveraging insight awareness along with metrics that matter drives return on investment (ROI) along with enhanced service delivery.

    • View other upcoming and recent events at the Server StorageIO activities page here.

    What This All Means

    What this all means is that the key to making smart, informed decisions involving data infrastructure, servers, storage, I/O across different applications is having insight and awareness. See for yourself how you can gain insight into your existing information factory environment performing analysis, as well as comparing and simulating your application workloads for informed decision-making.

    Having insight and awareness (e.g. instruments) allows you to avoid flying blind, enabling smart, safe and informed decisions in different conditions impacting your data infrastructure. How is your investment in hardware, software, services and tools being leveraged to meet given levels of services? Is your information factory (data center and data infrastructure) performing at its peak effectiveness?

    How are you positioned to support growth, improve productivity, remove complexity and costs while evolving from a legacy to a next generation software-defined, cloud, virtual, converged or hyper-converged environment with new application needs?

    Data infrastructure insight benefits and takeaways:

    • Informed performance-related decision-making
    • Support growth, agility, flexibility and availability
    • Maximize resource investment and utilization
    • Find, fix and remove I/O bottlenecks
    • Puts you in control in the driver’s seat

    Remember to register and attend the October 27 webinar that you can register here.

    Btw, Virtual Instruments has been a client of Server StorageIO and that fwiw is a disclosure.

    Happy 20th Birthday Microsoft Windows Server, get ready for Windows Server 2016

    Happy 20th Birthday Windows Server, ready for Server 2016?

    server storage I/O trends

    In case you have not heard, Microsoft is celebrating the 20th birthday (or anniversary) of Windows Server.

    Microsoft has a nice site with info graphics and timelines of where Windows Server has been and accomplished over the past 20 years (view here).

    Some of you may remember from 20 years ago Windows Server with a different name aka Windows NT Server. Back in the day, if you recall (or read), server requirements were more in the 33 MHz vs. 3.3GHz range, 32MB of RAM Memory vs. 32GB to 320GB, 150MB HDD vs. 150GB SSD or 1.5TB HDD.

    Keep in mind that 20 years ago Linux was a relative new thing with Red Hat not yet quite household or more specific enterprise name. The various Unix (e.g. IBM AIX, HP HP-UX, Sun Solaris, DEC Unix and Ultrix among many others) were still dominate, OS2 had peaked or close to, among others. Virtual Machines were Logical Partitions (LPAR) on Mainframes along with virtual PCs software and hardware assist boards.

    IMHO there is no coincidence of Microsoft celebrating 20 years of WIndows Server going into the fall of 2016 and the upcoming release of Server 2016.

    What’s New in Server 2016 (TP5)?

    If you have not done so, check out the latest Tech Preview 5 (TP5) of Windows Server 2016 (get the bits e.g. software here to try) which includes Storage Spaces Direct (S2D) that leverages internal PCIe and drive format SSD (NVMe, SAS, SATA) along with HDDs (SAS, SATA) for creating local and scale-out converged (desegregated) and hyper-converged (aggregated) solutions. In addition to S2D there is Storage Replica (SR) which is replication of local storage part of S2D (not to be confused with DFS or other replication).

    Other enhancements include ReFS as the default file system instead of NTFS (don’t worry, NTFS like FAT does not go away yet). There are enhancements to Hyper-V including VM shielding, hot-plug virtual network adapters, enhanced Linux support and fail over priorities among others. Other enhancements include updates for AD including improved integration with on-premises as well as Azure AD for hybrid environments, PowerShell updates, Docker management including Linux (via Hyper-V) and Windows via Nano) container engines.

    Microsoft Windows Server 2016 TP5

    Speaking of Nano, if you had not heard, this is a new very light weight Windows Kernel that removes 32 bit WOW and GUI support. The result is that Nano is a very small physical (under 1GB image instance size) using less disk, less memory and less CPU to do a given amount of work, oh, and boots super fast, even without SSD. By not having all the 32 bit and GUI overhead, the intent with Nano is there should be fewer updates and maintenance tasks to do, while enabling Windows containers for SQL Server and other applications.

    In addition to PowerShell, AD and other management enhancements, Windows Server 2016 (TP5) also enables bridging two worlds e.g. traditional on-premises (or cloud) based Windows Server and Public Cloud (e.g. Azure) and Private or Hybrid including Azure Stack. Note that if you have not heard of Azure Stack and are looking at cloud stacks such as OpenStack, do your due diligence and at least familiarize yourself with Azure Stack.

    View more about WIndows 2016 TP5 enhancements here.

    What This All Means

    Congratulations Microsoft and Windows Server on 20th birthday (anniversary) you have come a long way.

    With the new features and functionality in Windows Server 2016, looks like there is still a good future for the software defined server.

    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)

    server storage I/O trends

    Updated 2/2/2018

    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.

    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.

    Server storage I/O performance benchmark workload scripts Part I

    Server storage I/O performance benchmark workload scripts Part I

    Server storage I/O performance benchmark workload scripts

    Update 1/28/2018

    This is part one of a two-part series of posts about Server storage I/O performance benchmark workload tools and scripts. View part II here which includes the workload scripts and where to view sample results.

    There are various tools and workloads for server I/O benchmark testing, validation and exercising different storage devices (or systems and appliances) such as Non-Volatile Memory (NVM) flash Solid State Devices (SSDs) or Hard Disk Drives (HDD) among others.

    NVMe ssd storage
    Various NVM flash SSD including NVMe devices

    For example, lets say you have an SSD such as an Intel 750 (here, here, and here) or some other vendors NVMe PCIe Add in Card (AiC) installed into a Microsoft Windows server and would like to see how it compares with expected results. The following scripts allow you to validate your system with those of others running the same workload, granted of course your mileage (performance) may vary.

    server storage I/O SCM NVM SSD performance

    Why Your Performance May Vary

    Reasons you performance may vary include among others:

    • GHz Speed of your server, number of sockets, cores
    • Amount of main DRAM memory
    • Number, type and speed of PCIe slots
    • Speed of storage device and any adapters
    • Device drivers and firmware of storage devices and adapters
    • Server power mode setting (e.g. low or balanced power vs. high-performance)
    • Other workload running on system and device under test
    • Solar flares (kp-index) among other urban (or real) myths and issues
    • Typos or misconfiguration of workload test scripts
    • Test server, storage, I/O device, software and workload configuration
    • Versions of test software tools among others

    Windows Power (and performance) Settings

    Some things are assumed or taken for granted that everybody knows and does, however sometimes the obvious needs to be stated or re-stated. An example is remembering to check your server power management settings to see if they are in energy efficiency power savings mode, or, in high-performance mode. Note that if your focus is on getting the best possible performance for effective productivity, then you want to be in high performance mode. On the other hand if performance is not your main concern, instead a focus on energy avoidance, then low power mode, or perhaps balanced.

    For Microsoft Windows Servers, Desktop Workstations, Laptops and Tablets you can adjust power settings via control panel and GUI as well as command line or Powershell. From command line (privileged or administrator) the following are used for setting balanced or high-performance power settings.

    Balanced

    powercfg.exe /setactive 381b4222-f694-41f0-9685-ff5bb260df2e

    High Performance

    powercfg.exe /setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c

    From Powershell the following set balanced or high-performance.

    Balanced
    PowerCfg -SetActive "381b4222-f694-41f0-9685-ff5bb260df2e"

    High Performance
    PowerCfg -SetActive "8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c"

    Note that you can list Windows power management settings using powercfg -LIST and powercfg -QUERY

    server storage I/O power management

    Btw, if you have not already done so, enable Windows disk (HDD and SSD) performance counters so that they appear via Task Manager by entering from a command prompt:

    diskperf -y

    Workload (Benchmark) Simulation Test Tools Used

    There are many tools (see storageio.com/performance) that can be used for creating and running workloads just as there are various application server I/O characteristics. Different server I/O and application performance attributes include among others read vs. write, random vs. sequential, large vs. small, long vs. short stride, burst vs. sustain, cache and non-cache friendly, activity vs. data movement vs. latency vs. CPU usage among others. Likewise the number of workers, jobs, threads, outstanding and overlapped I/O among other configuration settings can have an impact on workload and results.

    The four free tools that I’m using with this set of scripts are:

    • Microsoft Diskspd (free), get the tool and bits here or here (open source), learn more about Diskspd here.
    • FIO.exe (free), get the tool and bits here or here among other venues.
    • Vdbench (free with registration), get the tool and bits here or here among other venues.
    • Iometer (free), get the tool and bits here among other venues.

    Notice: While best effort has been made to verify the above links, they may change over time and you are responsible for verifying the safety of links and your downloads.

    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

    Remember, everything is not the same in the data center or with data infrastructures that support different applications.

    While some tools are more robust or better than others for different things, ultimately it’s usually not the tool that results in a bad benchmark or comparison, it’s the configuration or lack of including workload settings that are not relevant or applicable. The best benchmark, workload or simulation is your own application. Second best is one that closely resembles your application workload characteristics. A bad benchmark is one that has no relevance to your environment, application use scenario. Take and treat all benchmark or workload simulation results with a grain of salt as something to compare, contrast or make reference to in the proper context. Read part two of this post series to view test tool workload scripts along with sample results.

    Updated 1/28/2018

    This is the second in a two part series of posts pertaining to using some common server storage I/O workload benchmark tools and scripts. View part I here which includes overview, background and information about the tools used and related topics.

    NVMe ssd storage
    Various NVM flash SSD including NVMe devices

    Following are some server I/O benchmark workload scripts to exercise various storage devices such as Non-Volatile Memory (NVM) flash Solid State Devices (SSDs) or Hard Disk Drives (HDD) among others.

    The Workloads

    Some ways that can impact the workload performance results besides changing the I/O size, read write, random sequential mix is the number of threads, workers and jobs. Note that in the workload steps, the larger 1MB and sequential scenarios have fewer threads, workers vs. the smaller IOP or activity focused workloads. Too many threads or workers can cause overhead and you will reach a point of diminishing return at some point. Likewise too few and you will not drive the system under test (SUT) or device under test (DUT) to its full potential. If you are not sure how many threads or workers to use, run some short calibration tests to see the results before doing a large, longer test.

    Keep in mind that the best benchmark or workload is your own application running with similar load to what you would see in real world, along with applicable features, configuration and functionality enabled. The second best would be those that closely resemble your workload characteristics and that are relevant.

    The following workloads involved a system test initiator (STI) server driving workload using the different tools as well as scripts shown. The STI sends the workload to a SUT or DUT that can be a single drive, card or multiple devices, storage system or appliance. Warning: The following workload tests does both reads and writes which can be destructive to your device under test. Exercise caution on the device and file name specified to avoid causing a problem that might result in you testing your backup / recovery process. Likewise no warranty is given, implied or made for these scripts or their use or results, they are simply supplied as is for your reference.

    The four free tools that I’m using with this set of scripts are:

    • Microsoft Diskspd (free), get the tool and bits here or here (open source), learn more about Diskspd here.
    • FIO.exe (free), get the tool and bits here or here among other venues.
    • Vdbench (free with registration), get the tool and bits here or here among other venues.
    • Iometer (free), get the tool and bits here among other venues.

    Notice: While best effort has been made to verify the above links, they may change over time and you are responsible for verifying the safety of links and your downloads

    Microsoft Diskspd workloads

    Note that a 300GB size file named iobw.tst on device N: is being used for performing read and write I/Os to. There are 160 threads, I/O size of 4KB and 8KB varying from 100% Read (0% write), 70% Read (30% write) and 0% Read (100% write) with random (seek) and no hardware or software cache. Also specified are to collect latency statistics, a 30 second warm up ramp up time, and a quick 5 minute duration (test time). 5 minutes is a quick test for calibration, verify your environment however relatively short for a real test which should be in the hours or more depending on your needs.

    Note that the output results are put into a file with a name describing the test tool, workload and other useful information such as date and time. You may also want to specify a different directory where output files are placed.

    diskspd.exe -c300G -o160 -t160 -b4K -w0 -W30 -d300 -h -fr  N:iobw.tst -L  > DiskSPD_300G_4KRan100Read_160x160_072416_8AM.txt
diskspd.exe -c300G -o160 -t160 -b4K -w30 -W30 -d300 -h -fr  N:iobw.tst -L  > DiskSPD_300G_4KRan70Read_160x160_072416_8AM.txt
diskspd.exe -c300G -o160 -t160 -b4K -w100 -W30 -d300 -h -fr  N:iobw.tst -L  > DiskSPD_300G_4KRan0Read_160x160_072416_8AM.txt
diskspd.exe -c300G -o160 -t160 -b8K -w0 -W30 -d300 -h -fr  N:iobw.tst -L  > DiskSPD_300G_8KRan100Read_160x160_072416_8AM.txt
diskspd.exe -c300G -o160 -t160 -b8K -w30 -W30 -d300 -h -fr  N:iobw.tst -L  > DiskSPD_300G_8KRan70Read_160x160_072416_8AM.txt
diskspd.exe -c300G -o160 -t160 -b8K -w100 -W30 -d300 -h -fr  N:iobw.tst -L  > DiskSPD_300G_8KRan0Read_160x160_072416_8AM.txt

    The following Diskspd tests use similar settings as above, however instead of random, sequential is specified, threads and outstanding I/Os are reduced while I/O size is set to 1MB, then 8KB, with 100% read and 100% write scenarios. The -t specifies the number of threads and -o number of outstanding I/Os per thread.

    diskspd.exe -c300G -o32 -t132 -b1M -w0 -W30 -d300 -h -si  N:iobw.tst -L  > DiskSPD_300G_1MSeq100Read_32x32_072416_8AM.txt

    Fio.exe workloads

    Next are the fio workloads similar to those run using Diskspd except the sequential scenarios are skipped.

    fio --filename=N\:\iobw.tst --filesize=300000M --direct=1  --rw=randrw --refill_buffers --norandommap --randrepeat=0 --ioengine=windowsaio  --ba=4k --bs=4k --rwmixread=100 --iodepth=32 --numjobs=5 --exitall --time_based  --ramp_time=30 --runtime=300 --group_reporting --name=xxx  --output=FIO_300000M_4KRan100Read_5x32_072416_8AM.txt

    Vdbench workloads

    Next are the Vdbench workloads similar to those used with the Microsoft Diskspd scenarios. In addition to making sure Vdbench is installed and working, you will need to create a text file called seqrxx.txt containing the following:

    hd=localhost,jvms=!jvmn
    
sd=sd1,lun=!drivename,openflags=directio,size=!dsize
    
wd=mix,sd=sd1
    
rd=!jobname,wd=mix,elapsed=!etime,interval=!itime,iorate=max,forthreads=(!tthreads),forxfersize=(!worktbd),forseekpct=(!workseek),forrdpct=(!workread),openflags=directio

    The following are the commands that call the Vdbench script file. Note Vdbench puts output files (yes, plural there are many results) in a output folder.

    vdbench -f seqrxx.txt dsize=300G  tthreads=160 jvmn=64 worktbd=4k workseek=100 workread=100 jobname=NVME etime=300 itime=30 drivename="\\.\N:\iobw.tst" -o  vdbench_NNVMe_300GB_64JVM_160TH_4K100Ran100Read_0726166AM

    Iometer workloads

    Last however not least, lets do an Iometer run. The following command calls an Iometer input file (icf) that you can find here. In that file you will need to make a few changes including the name of the server where Iometer is running, description and device under test address. For example in the icf file change SIOSERVER to the name of the server where you will be running Iometer from. Also change the address for the DUT, for example N: to what ever address, drive, mount point you are using. Also update the description accordingly (e.g. "NVME" to "Your test example".

    Here is the command line to run Iometer specifying an icf and where to put the results in a CSV file that can be imported into Excel or other tools.

    iometer /c  iometer_5work32q_intel_Profile.icf /r iometer_nvmetest_5work32q_072416_8AM.csv

    server storage I/O SCM NVM SSD performance

    What About The Results?

    For context, the following results were run on a Lenovo TS140 (32GB RAM), single socket quad core (3.2GHz) Intel E3-1225 v3 with an Intel NVMe 750 PCIe AiC (Intel SSDPEDMW40). Out of the box Microsoft Windows NVMe drive and controller drivers were used (e.g. 6.3.9600.18203 and 6.3.9600.16421). Operating system is Windows 2012 R2 (bare metal) with NVMe PCIe card formatted with ReFS file system. Workload generator and benchmark driver tools included Microsoft Diskspd version 2.012, Fio.exe version 2.2.3, Vdbench 50403 and Iometer 1.1.0. Note that there are newer versions of the various workload generation tools.

    Example results are located here.

    What This All Means

    Remember, everything is not the same in the data center or with data infrastructures that support different applications.

    While some tools are more robust or better than others for different things, ultimately its usually not the tool that results in a bad benchmark or comparison, its the configuration or lack of including workload settings that are not relevant or applicable. The best benchmark, workload or simulation is your own application. Second best is one that closely resembles your application workload characteristics. A bad benchmark is one that has no relevance to your environment, application use scenario. Take and treat all benchmark or workload simulation results with a grain of salt as something to compare, contrast or make reference to in the proper context.

    Ok, nuff said, for now.

    12Gb SAS SSD Enabling Server Storage I/O Performance and Effectiveness Webinar

    12Gb SAS SSD Enabling Server Storage I/O Performance and Effectiveness Webinar

    server storage I/O trends

    Non-Volatile Memory (NVM) Solid State Devices (SSDs) including nand flash, DRAM as well as emerging PCM and 3D XPoint as part of Storage Class Memories (SCMs) are in your future. The questions are where, when, for what, how much as well as what form factor packaging, along with server storage I/O interface are applicable for your different applications and data infrastructures.

    server storage I/O SCM NVM SSD performance

    Server storage I/O physical interfaces for access NVM SSDs include PCIe Add in Cards (AiC), M.2 as well as emerging SFF 8639 (e.g. NVMe U2 drive form factor) along with mSATA (e.g. mini PCIe card) in addition to SAS, SATA, USB among others. Protocols include NVM Express (NVMe), SAS, SATA as well as general server storage I/O access of shared storage systems that leverage NVM SSD and SCM technologies.

    To help address the question of which server storage I/O interface is applicable for different environments, I invite you to a webinar on June 22, 2016 at 1PM ET hosted by and compliments of Micron.

    During the webinar myself and Rob Peglarr (@peglarr) of Micron will discuss and answer questions about how 12Gb SAS remains a viable option for attach NVM SSD storage to servers, as well as via storage systems today and into the future. Today’s 12Gb SAS SSDs enable you to leverage your existing knowledge, skill sets, as well as technology to maximize your data infrastructure investments. For servers or storage systems that are PCIe slot constrained, 12Gb SAS enables more SSD including 2.5" form factor multiple TByte capacity devices to be used to boost performance and capacity in a cost as well as energy effective way.

    server storage I/O nvm ssd options

    In addition to Rob Peglarr, we will also be joined by Doug Rollins of Micron (@GreyHairStorage) who will share some technical speeds, feeds, slots and watts information about Micron 12Gb SAS SSDs that can scale into the TBs in capacity per device.

    Here’s the synopsis from the Micron information page for this webinar.

    Don’t let old, slow SAS HDDs drag down your data center

    Modernize it by upgrading your storage from SAS HDDs to SAS SSDs. It’s an easy upgrade that provides a significant boost in performance, longer lasting endurance and nearly 4X the capacity. Flash storage changes how you do business and keeps you competitive.

    We invite you to join Rob Peglar, Greg Schulz, along with Doug Rollins, from Micron’s technical marketing team to learn:

    • Simple solutions to solving the challenges with today’s ever-growing data demands
    • Why SAS—how it continues to fuel the data center
    • HDDs versus SDDs—before and after stories from your peers, including upfront cost savings

    We will also have a live Q&A session so you can talk with the experts. Please register today! If you’re unable to attend the live webinar, we encourage you to register anyway to receive a link to the recorded session, as well as a copy of the presentation.

    What This All Means

    There is a lot of things occurring in the IT industry from physical to software defined clouds, containers and virtualization, nonvolatile memory (NVM) including flash SSD among others. These series of interactive educational workshop seminars converge on Nijkerk Holland combing content discussions from strategy, planning decision making, to what’s new (and old) that can be used in new ways, as well as some trends, speeds and feeds along with practicality for your environment.

    EMCworld 2016 EMC Hybrid and Converged Clouds Your Way

    EMCworld 2016 EMC Hybrid and Converged Clouds Your Way

    server storage I/O trends

    This is a quick post looking at a high-level view of today’s EMCworld 2016 announcements.

    Following up from yesterdays post covering the set of announcements, today’s theme is around Hybrid, Converged and Clouds your way. In addition to the morning announcements, EMC also yesterday afternoon announced InfoArchive 4.0 and EMC LEAP cloud native content applications for Enterprise Content Management (ECM). However lets focus on today’s announcements with a focus of modernize, transform and automate your date center.

    Today’s announcements include:

    • Cloud solution portfolio enhancements with Native Hybrid Cloud (NHC) turnkey developer platform for cloud native application development. NHC editions include those for VMware vSphere, OpenStack and VMware Photo Platform. Read more here.

    • VCE VxRack System 1000 with new Neutrino Nodes which are software defined hyper-converged rack scale solutions to support turnkey cloud (public, private, hybrid) implementations. Read more about VxRack System 1000 with links here.

    • NVMe based DSSD D5 flash SSD system enhancements include ability to stripe two systems together in a single rack to double the IOPs, bandwidth and capacity. Also new is a VCE VxRack system with DSSD. Read more about DSSD D5 enhancements here.

    What This All Means

    For those of you who have installed OpenStack either from scratch, or using one of the appliances, you understand what’s involved with doing so. The point is that for those who are in the business or jobs are based on installing or configuring or software defining the software and cloud configurations, turnkey solutions may not be a fit, or at least yet. On the other hand, if your focus is doing other things and are looking for boosting productivity, then turnkey solutions are a way of fast tracking deployment. Likewise for those who have the need for more speed from bandwidth or IOPs, the DSSD D5 enhancements will help in those environments.

    EMCworld 2016 Getting Started on Dell EMC announcements

    EMCworld 2016 Getting Started on Dell EMC announcements

    server storage I/O trends

    It’s the first morning of EMCworld 2016 here in Las Vegas with some items already announced today, and more in the wings. One of the underlying themes and discussions besides what’s new or who’s doing what, is that this is for all practical purpose the last EMCworld with the upcoming Dell acquisition. What’s not clear is will there be a renamed and repackaged Dell/EMCworld?

    With current EMC President Jeremy Burton who used to be the Chief Marketing Officer (CMO) at EMC slated to become the CMO across all of Dell, my bet is that there will be some type of new event picking up and moving to a new level of where EMCworld and Dellworld have been. More on the future of EMC and Dell in future posts, however for now, lets see what has unfolded so far today.

    Today’s EMCworld theme is modernize the data center which means a mix of hardware, software and services announcements spanning physical, virtual, cloud among others (e.g. how do you want your servers, storage and data infrastructure wrapped). While the themes are still EMC as the Dell acquisition has yet to be completed, however there is a Dell presence, including Michael Dell here in person (more on Dell later).

    The first wave of announcements include:

    • Unity All Flash Array (AFA) for small, entry-level environments
    • EMC Enterprise Copy Data Management software tools portfolio
    • ViPR Version 3.0 Controller
    • Virtustream global hyper-scale Storage Cloud for data protection and cloud native object
    • MyService360

    • Datadomain virtual edition and long-term archive

    What About The Dell Deal

    Michael Dell who is here at EMCworld announced on the main stage that Dell Technologies will be the name of the families of business.

    This family of business includes the joint Dell, EMC, VMware, Pivotal, Secureworks, RSA and Virtustream. The Dell client focused business will be called Dell leveraging

    that Brand, while the new joint Dell and EMC enterprise business will be called Dell EMC leveraging both of those brands. As a reminder, the Dell servers business unit will be moving into the existing EMC business as part of the enterprise business unit.

    Lets move onto the technology announcements from today.

    Unity AFA (and Hybrid)

    The new Unity all flash array (AFA) is a dual controller storage system optimized for Nonvolatile Memory (NVM) flash SSD, with unified (block and file) access. EMC is positioning Unity as an entry-level AFA starting around $18K USD for a 2U solutions (much capacity that includes is not yet known, more on that in a future post). As well as having a low entry cost, EMC is positioning Unity for a broad, mass market, volume distribution that can be leveraged by their partners, including Dell. More on Unity in future posts. While Unity is new and modern, it comes from the same group who has created the VNXe leveraging that knowledge and skills base.

    Note that Unity is positioned for small, mid-sized, remote office branch office (ROBO), departmental and specialized AFA situations, where EMC NVMe based DSSD D5 is positioned for higher-end shared direct attached server flash, while XtremIO and VMAX also positioned for higher-end, higher performance and workload consolidation scenarios.

    • Simple, flexible, easy to use in a 2U packaging that scale up to 80TB of NVM flash SSD storage
    • Scalable up to 3PB of storage for larger expanded configurations
    • Affordable ($18K USD starting price, $10K entry-level hybrid)
    • Modern AFA storage for entry, small, mid-sized, workgroup, departments and specialized environments
    • Unified file, block, and VMware VVOL support for storage access
    • Also available in hybrid, as well as software defined virtual and converged configurations
    • Higher performance (EMC indicates 300,000 IOPs) for given entry-level systems
    • Available in all-flash array, hybrid array, software-defined and converged configurations
    • Native controller based encryption with synchronous and asynchronous replication
    • VMware VASA 2.0, VAAI, VVols and VMware integration
    • Tight integration with EMC Data Protection portfolio tools

    Read more about Unity here.

    Copy Data Management

    Enterprise Copy Data Management (eCDM) spans data copies from data protection including backup, BC, DR as well as for operational, analytics, test, dev, devops among other uses. Another term is Enterprise Copy Data Analytics (eCDA) which includes monitoring and management along with insight, awareness and of course analytics. These new offerings and initiatives tie together various capabilities across storage platforms and software defined storage management. Watch for more activity in and around eCDM and general copy data management. Read more here.

    ViPR Controller 3.0

    ViPR controller enhancements build on previous announcements, include automation as well as fail over with native replication to a standby ViPR controller. Note that there can actually be two standby controllers that are synchronized asynchronous with software built-in to ViPR. This means that there is no need for RecoverPoint or other products to do the replication of the ViPR controllers. To be clear, this is for high availability of the ViPR controllers themselves and not a replacement for HA or replication of upper layer applications, storage servers or underlying storage services. Also note that ViPR is available via open source (CoprHD via Github here). Read more here.

    MyService360

    MyService360 is a cloud based dashboard and data infrastructure monitoring management platform. Read more here.

    Virtustream Storage Cloud

    Viutustream cloud services and software tools compliments EMC (and others) storage systems as back-end for cool, cold or other bulk data storage needs. Focus is to sell primary storage to customers, then leverage back-end public cloud services for backup, archive, copy data management and other applications. This also means that the Virtustream storage cloud is not just for data protection such as archiving, backup, BC, DR it’s also for other big fast data including cloud and object native applications. Does this mean Virtustream is an alternative to other cloud and object storage services such as AWS S3, Google GCS among others? Yup. Read more here.

    What This All Means

    With the announcement of Unity and impending Dell deal, some of you might (or should) have a Dejavu moment of over a decade or so ago when Dell and EMC entered into OEM agreement around the then Clariion mid range storage arrays (e.g. predecessors of VNX and VNXe). Unity is being designed as a high performance, easy to use, flexible, scalable, cost-effective storage solutions for a broad high-volume sales and distribution channel market.

    What does Unity mean for EMC VNX and VNXe as well as XtremIO? Unity will position near where the VNXe has been positioned, along with some of the competing solutions from Dell among others. There might be some overlap with other EMC solutions, however if executed properly, Unity should open up some new markets, perhaps at the hands of some of the newer popular startups that only offer AFA vs. hybrids. Likewise I would expect Unity to appear in future converged solutions such as those via the EMC Converged business unit (e.g. VCE).

    Even with the upcoming Dell acquisition and integration, EMC continues to evolve and innovate in many areas.

    Watch for more announcements later today and throughout the week
