    Data Recovery and Selective Erasure of Solid State Storage a New Focus at SNIA

    July 15th, 2015

    The rise of solid state storage has been incredibly beneficial to users in a variety of industries. Solid state technology presents a more reliable and efficient alternative to traditional storage devices. However, these benefits have not come without unforeseen drawbacks in other areas. For those in the data recovery and data erase industries, for example, solid state storage has presented challenges. The obstacles to data recovery and selective erasure capabilities are not only a problem for those in these industries, but they can also make end users more hesitant to adopt solid state storage technology.

    Recently a new Data Recovery and Erase Special Interest Group (SIG) has been formed within the Solid State Storage Initiative (SSSI) within the Storage Networking Industry Association (SNIA). SNIA’s mission is to “lead the storage industry worldwide in developing and promoting standards, technologies and educational services to empower organizations in the management of information.” This fantastic organization has given the Data Recovery and Erase SIG a solid platform on which to build the initiative.

    The new group has held a number of introductory open meetings for SNIA members and non-members to promote the group and develop the group’s charter. For its initial meetings, the group sought to recruit both SNIA members and non-members that were key stakeholders in fields related to the SIG. This includes data recovery providers, erase solution providers and solid state storage device manufacturers. Aside from these groups, members of leading standards bodies and major solid state storage device consumers were also included in the group’s initial formation.

    The group’s main purpose is to be an open forum of discussion among all key stakeholders. In the past, there have been few opportunities for representatives from different industries to work together, and collaboration had often been on an individual basis rather than as a group. With the formation of this group, members intend to cooperate between industries on a collective basis in order to foster a more constructive dialogue incorporating the opinions and feedback of multiple parties.

    During the initial meetings of the Data Recovery and Erase SIG, members agreed on a charter to outline the group’s purpose and goals. The main objective is to foster collaboration among all parties to ensure consumer demands for data recovery and erase services on solid state storage technology can be performed in a cost-effective, timely and fully successful manner

    In order to achieve this goal, the group has laid out six steps needed, involving all relevant stakeholders:

    1. Build the business case to support the need for effective data recovery and erase capabilities on solid state technology by using use cases and real examples from end users with these needs.
    2. Create a feedback loop allowing data recovery providers to provide failure information to manufacturers in order to improve product design.
    3. Foster cooperation between solid state manufacturers and data recovery and erase providers to determine what information is necessary to improve capabilities.
    4. Protect sensitive intellectual property shared between data recovery and erase providers and solid state storage manufacturers.
    5. Work with standards bodies to ensure future revisions of their specifications account for capabilities necessary to enable data recovery and erase functionality on solid state storage.
    6. Collaborate with solid state storage manufacturers to incorporate capabilities needed to perform data recovery and erase in product design for future device models.

    The success of this special interest group depends not only on the hard work of the current members, but also in a diverse membership base of representatives from different industries. We will be at Flash Memory Summit in booth 820 to meet you in person! Or you can visit our website at www.snia.org/forums/sssi for more information on this new initiative and all solid state storage happenings at SNIA.   If you’re a SNIA member and you’d like to learn more about the Data Recovery/Erase SIG or you think you’d be a good fit for membership, we’d love to speak with you.  Not a SNIA member yet?

    New SIG for SSD Data Recovery/Erase Formed – Calls Open to All Interested Participants

    April 26th, 2015

    SSDs present particular challenges when trying to erase all data or attempting to recover data from a broken drive. To address these issues, a new Data Recovery/Erase Special Interest Group has been formed within the SNIA Solid State Storage Initiative.

    The goal of the SIG is to provide a forum in which solution providers and solid state storage manufacturers can collaborate to enable data recovery and erase capabilities in solid state storage in such a way as to ensure that customer demands for these services can be met in a cost-effective and timely manner, with a high likelihood of success. A key to the success of the SIG is obtaining input and participation from all of the key stakeholders: solid state storage manufacturers, data recovery and erase solution providers, and solid state storage customers.

    The SIG will be having a limited number of conference calls that will be open to non-members. Go to http://www.snia.org/forums/sssi/dresig for more details and to register for the first open meeting.

    SSSI Sheds Light on Solid State Storage at Flash Memory Summit

    August 22nd, 2013

    If you attended Flash Memory Summit along with thousands of other business professionals, you soon learned that solid state keynotes, breakouts, and show floor booths, while informative, could be mystifying.  Fortunately, the SNIA Solid State Storage Initiative (SSSI) was at FMS to provide enlightenment in the form of a SSS Reception, four new publications on SSS, and three SSSI member demonstrations.

    SSSI’s second annual SSS Reception was attended by over 90 individualIMG_6196s and featured presentations by SSSI Governing Board members Paul Wassenberg of Marvell, Walt Hubis of Fusion-io, and Eden Kim of Calypso Systems on SSSI key programs and technical work.   SSSI Education Chair Tom Coughlin of Coughlin Associates delivered a market update on ubiquitous flash memory.   All SSSI members are eligible and encouraged to join specification development, education, and outreach programs, and new companies are welcome to join SSSI activities.

    At the SSSI Booth, attendees snapped up new white papers and Tech Notes authored by SSSI members.  These papers are complimentary to all interested individuals and available on the SSSI education page.

    • The PCI Express (PCIe) 101 – An Overview of Standards, Markets, and Performance white paper surveys the broad landscape of emerging high performance PCIe storage and the implications of revolutionary applications of these new architectures.  Thirteen members of the SNIA SSSI PCIe SSD Committee representing eleven SNIA and SSSI member companies contributed their technical expertise to this paper, which covers standards, programming models for non-volatile memory, the PCIe SSD market, and PCIe SSD performance.
    • The SSD Performance – A Primer white paper, authored by SNIA SSS Technical Work Group chair Eden Kim of Calypso Systems, provides an introduction to solid state drive performance, evaluation, and test.  As noted in the Foreword by SSSI Founder and 2008-2010 SSSI Chair Phil Mills of IBM, “this paper is an excellent tutorial on the performance of solid state drives, which covers this topic in a very easy to understand way, yet provides detailed technical information that the reader can either dig into for a better understanding, or simply skip without missing the main points”.
    • A new PTS User Guide Tech Note delivers the hows and whys of the SNIA Solid State Performance Test Specification.  Authored by SNIA SSSI members Eden Kim of Calypso Systems and Chuck Paradon of HP, this Tech Note provides an easy to understand, step-by step guide to using the SNIA SSS Performance Test Specification (PTS) test methodologies and tests. The Tech Note discusses four basic PTS 1.1 tests – Write Saturation (WSAT), IOPS, Throughput (TP) and Response Time (or Latency) – as updated per SNIA draft PTS-E version 1.1.
    • The SSSI Workload I/O Capture Program (WIOCP) FAQ, authored by SNIA SSSI member Tom West of hyperI/O LLC, gives details on this project undertaken by the SNIA SSSI to collect I/O operation performance metrics. These empirical metrics reflect the actual I/O operation activity performed during normal, everyday application/workload usage spanning both consumer/client and enterprise systems.

    PCI Express Coming to an SSD Near You

    August 2nd, 2013

    There’s been a lot of press recently about what’s going on in the world of storage regarding the utilization of PCIe as a device interface.  Of course, PCIe has been around a long time as a system bus, while SATA and SAS have been used as storage device interfaces.  But with SSDs getting faster with every new product release, it’s become difficult for the traditional interfaces to keep up.

    Some folks figure that PCIe is the solution to that problem.  PCIe 3.0 operates at 1GB/s, which is faster than 600MB/s SATA.  And with PCIe, it’s possible to add lanes to increase the overall bandwidth.  The SATA Express spec from SATA-IO defines a client PCIe device as having up to 2 lanes of PCIe, which brings the speed up to 2GB/s.  Enterprise SSDs will have up to 4 lanes of PCIe, which provides 4GB/s of bandwidth.

    There was also some work on the software side that needed to be done to support PCIe devices, including NVM Express and SCSI Over PCIe (SOP), both of which are well underway.

    If you are interested in knowing more about PCIe SSDs, keep an eye on our Education page, where, sometime during the week of August 5, we will be posting a new white paper on this topic.
