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!

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 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.
