Solid State on Stage

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

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

Solid State A Winner at Flash Memory Summit

SNIA Solid State Storage Initiative (SSSI) enjoyed a lively following at the recent Flash Memory Summit in Santa Clara CA.

PCIe SSD was a favorite topic.  A Tuesday Chat with the Experts found SSSI members Eden Kim (PCIe Flash), Paul Wassenberg (SATA Express), and Jim Pappas (Solid State Storage Standards) speaking to full tables.  A SSSI-sponsored PCIe SSD panel on Thursday moderated by Eden Kim of Calypso Systems included talks on PCIe performance testing, SATA Express, PCIe 2.5 form factor, SCSI Express, and PCIe and Storage Class Memory.  The SSSI booth was packed with individuals and companies eager to learn more about our PCIe SSD, NVM programming, and workload I/O capture program activities.

Solid state technology dominated sessions and the show floor.  SSSI Marketing Chair Tom Coughlin of Coughlin Associates gives his technology perspective of the show in his Storage Bytes blog for Forbes at http://blogs.forbes.com/tomcoughlin/.  Check it out and let us know your thoughts!

Updated Client Solid State Performance Test Specification Now Available

SNIA’s Solid State Storage Initiative has just released a revised Client SSS Performance Test Specification (PTS-Client) which adds a new write saturation test and refines existing tests.

The Solid State Storage Performance Test Specification (PTS) is a device-level performance test suite for benchmarking and comparing performance among SAS, SATA and PCI Express SSDs

Revision 1.1 of the PTS-Client updates tests for IOPS, throughput and latency to more accurately reflect the workload conditions under which Client SSDs are used.  The PTS-Client v1.1 also adds a Write Saturation test that measures the initial Fresh-Out-of-Box state of SSDs and their performance evolution as data is randomly written to the device.

Eden Kim, Chair of SNIA’s SSS Technical Working Group, describes the primary updates to PTS-Client v1.1 as adjustments to preconditioning ranges and test boundaries.   Taken together, these parameters create a repeatable test stimulus that more accurately reflects the workload characteristics of SSDs used in a single user environment The PTS-Client v1.1 also adds an easily understandable description of each test, which helps the user to understand the purpose of the test, the test flow, and guidance on how to interpret the test results.

Sample test results using the PTS-Client v1.1 have been posted to the SNIA SSSI Understanding PTS Performance webpage.
