    How Many IOPS Is Enough?

    May 22nd, 2013

    SNIA’s SSSI channel webcast of “How Many IOPS Is Enough?” was a smash success!  Now you can listen to an on demand rebroadcast.

    Even though there are lots of SSDs on the market today offering IOPS (I/Os Per Second) performance in the thousands to hundreds of thousands (with indications that future models will offer speeds in the million-IOPS range), and HDDs that support from tens to hundreds of IOPS depending on spindle speed and interface, not every application can use the extreme performance of high-end SSDs, and some may not benefit from high IOPS at all.

    Since performance is tied to cost, users can save money if they understand how many IOPS the system really needs.  ”How Many IOPS is Enough?” draws from the recent study by Coughlin Associates and Objective Analysis that examined what makes an application require high IOPS and which profiled applications according to their needs.

    In the webcast, you will also learn how to take part in an exciting SSSI project - the Workload I/O Capture Program, or WIOCP, a simple tool that captures software applications’ I/O activity by gathering statistics on workloads at the user level (IOPS, MB/s, response times queue depths, etc).  The WIOCP helps users to identify “Hot Spots” where storage performance is creating bottlenecks. SNIA SSSI hopes that users will help the association to collect real-use statistics on workloads by uploading their results to the SNIA website. Details on WIOCP can be found at tinyurl.com/tryWIOCP.


    New Performance Test Service Launched for Solid State Drives

    April 20th, 2013

    The SNIA Solid State Storage Initiative (SNIA SSSI) announces a testing service where interested parties may submit their SSD products for testing to the SSS Performance Test Specification.

    Drive Requirements

    Any mSATA, SATA, SAS and PCIe SSDs can be tested. The tested device must be recognized as a logical device by CentOS 6.3 and must support Purge (via Security Erase, Format Unit, or equivalent proprietary method of Purge).

    Available Tests

    Testing is based on the SSS PTS version 1.1.  Visit the SSS Performance Test Service page for more information on the tests.

    Testing Process

    Testing will be conducted by Calypso Systems, a certified SSS PTS testing facility.  Participants must submit two (2) samples of the SSD to be tested and provide prepaid return express shipment bills (FedEx, DHL or UPS). Testing will take approximately 3-4 weeks to complete.

    Any failed test, or test that will not complete, will be tested twice and error logs will be provided.  All product test result data will be kept confidential.

    Test results are provided in standard SNIA Report Format as specified in the SSS Performance Test Specification.

    For more details, contact ptstest@snia.org


    Reaching Nirvana? Maybe Not, But You Can Help In Better Understanding SSD and HDD Performance via SNIA’s Workload I/O Capture Program

    March 25th, 2013

    SNIA’s Solid State Storage Initiative (SSSI) recently rolled out its new Workload I/O Capture Program, or WIOCP, a simple tool that captures software applications’ I/O activity by gathering statistics on workloads at the user level (IOPS, MB/s, response times queue depths, etc).  The WIOCP helps users to identify “Hot Spots” where storage performance is creating bottlenecks. SNIA SSSI hopes that users will help the association to collect real-use statistics on workloads by uploading their results to the SNIA website.

    How it works
    The WIOCP software is a safe and thoroughly-tested tool which runs unobtrusively in the background to constantly capture a large set of SSD and HDD I/O metrics that are useful to both the computer user and to SNIA. Users simply enter the drive letters for those drives for which I/O operations metrics are to be collected. The program does not record anything that might be sensitive, including details of your actual workload (for example, files you’ve accessed.) Results are presented in clear and accessible report formats.

    How would the WIOCP help me as a user of computer systems?
    Our upcoming white paper gives many reasons why you would want to download and run the WIOCP.  One reason is that empirical file and disk I/O operation performance metrics can be invaluable with regard to theories and claims about disk I/O performance. This is especially so when these metrics reflect the actual file and disk I/O operation activity performed by individual applications/workloads during normal usage. Moreover, such empirical I/O metrics can be instrumental in uncovering/understanding performance “bottlenecks”, determining more precise I/O performance requirements, better matching disk storage purchases to the particular workload usage/needs, and designing/optimizing various disk storage solutions.

    How can I help this project?
    by downloading and running the WIOCP you help us collect I/O metrics, which can reveal insights into the particular ways that applications actually perform and experience I/O operation activity in “real-life” use. And using this information,  SNIA member companies will be able to improve the performance of their solid state storage solution, including SSDs and flash storage arrays. Help SNIA get started on this project by clicking http://www.hyperIO.com/hIOmon/hIOmonSSSIworkloadIOcaptureProgram.htm and using the “Download Key Code” enter SSSI52kd9A8Z. The WIOCP tool will be delivered to your system with a unique digital signature. The tool only takes a few minutes to download and initialize, after which you can return to the task at hand!

    Solid State on Stage

    October 30th, 2012

    The media buzz continues on solid state storage, now a prominent feature of storage, virtualization, and developer discussions.  Reaching the ears of business is SSSI’s Marketing Committee Chair Tom Coughlin, who has a blog on Forbes.  Latest posts discuss  a new age of digital storage interfaces, many based on the PCIe computer interface, that can take advantage of the higher data rates that NAND flash-based digital storage can provide.

    Solid State Storage was featured at recent storage conferences including SNIA’s Storage Developer Conference and SNW (Storage Networking World) US and Europe.  At SNW US, Lucas Mearian of Computerworld and Jim Pappas, SNIA Board and SSSI member, discussed a sea change in the non-volatile memory (NVM) market over the next five years, with more dense and reliable technologies challenging dominant NAND flash memory now used in solid-state drives (SSD) and embedded in mobile products.  Mearian’s article is here.

    At Powering the Cloud – SNW Europe, Randy Kerns of the SNIA member Evaluator Group led a spotlight session on Solid State Storage and Its Impact on the Environment, with presentations from SSSI members Kim Gardner of STEC and David Dale of NetApp.

    SNIA and the Solid State Storage Initiative urge you to get involved in fast-developing SSSI activities in PCIe and NVM.  Visit our website at http://www.snia.org/forums/sssi or email asksssi@snia.org


    SNIA Highlights NVM Programming TWG at Intel Developers Forum

    September 12th, 2012

    SNIA is proud to participate at the Intel Developers Forum this week at Moscone West In San Francisco.  Our booth in the NVM Express Community area focuses on SNIA and SSSI work in non volatile memory.

    Attendees are very interested in the newly launched SNIA NVM Programming Technical Work Group (NVMp TWG).

    The purpose of the NVMp TWG is to create specifications which will provide guidance to operating system, device driver, and application developers to be able to accelerate the availability of hardware-enabling Non-Volatile Memory (NVM) software.  A concrete example is database software which can use NVM to assure the database is available quickly after a system reboot.

    The TWG will develop two specifications. The first is for NVM Extensions between OS Components. The work on a first version is starting now with an expected completion of about Q4’12.  The second specification is for NVM Application Extensions; with the first version expected Q2’13.

    The Solid State Storage Initiative (SSSI) will  provide marketing and outreach support to the NVMp TWG, extending its educational mission.

    The NVMp TWG is supported by EMC, Fusion-io, HP, Intel (also chairs the TWG), LSI, NetApp, Oracle, Samsung, SanDisk, Seagate, Symantec, Toshiba, Virident, and VMware.  More companies are in the process of joining SNIA and the SSSI.

    If you are interested in the NVMp TWG, and/or want more information on SSSI activities  visit www.snia.org/forums/sssi
