    The Alphabet Soup of Storage Networking Acronyms Explained

    August 7th, 2017
    At our most recent webcast, “Everything You Wanted to Know About Storage But Were Too Proud To Ask: Part Turquoise – Where Does My Data Go?, our panel of experts dove into what really happens when you hit “save” and send your data off. It was an alphabet soup of acronyms as they explained the nuances of and the differences between:
    • Volatile v Non-Volatile v Persistent Memory
    • NVDIMM v RAM v DRAM v SLC v MLC v TLC v NAND v 3D NAND v Flash v SSDs v NVMe
    • NVMe (the protocol)
    As promised during the live event, here are answers to all the questions we received. Q. Is SRAM still used today? A. SRAM is still in use today as embedded CACHE (Level 1/2/3) within a CPU and very limited in external standalone packaging… This is due to cost and size/capacity.  Continue Reading...

    Latency Budgets for Solid State Storage Access

    March 7th, 2017

    New solid state storage technologies are forcing the industry to refine distinctions between networks and other types of system interconnects.  The question on everyone’s mind is: when is it beneficial to use networks to access solid state storage, particularly persistent memory?

    It’s not quite as simple as a “yes/no” answer. The answer to this question involves application, interconnect, memory technology and scalability factors that can be analyzed in the context of a latency budget.

    On April 19th, Doug Voigt, Chair SNIA NVM Programming Model Technical Work Group, returns for a live SNIA Ethernet Storage Forum webcast, “Architectural Principles for Networked Solid State Storage Access – Part 2where we will explore latency budgets for various types of solid state storage access. These can be used to determine which combinations of interconnects, technologies and scales are compatible with Load/Store instruction access and which are better suited to IO completion techniques such as polling or blocking.

    In this webcast you’ll learn:

    • Why latency is important in accessing solid state storage
    • How to determine the appropriate use of networking in the context of a latency budget
    • Do’s and don’ts for Load/Store access

    This is a technical seminar built upon part 1 of this series. If you missed it, you can view it on demand at your convenience. It will give you a solid foundation on this topic, outlining key architectural principles that allow us to think about the application of networked solid state technologies more systematically.

    I hope you will register today for the April 19th event. Doug and I will be on hand to answer questions on the spot.

    The Changing World of SNIA Technical Work – A Conversation with Technical Council Chair Mark Carlson

    August 3rd, 2016

    carlson_mark_resizeMark Carlson is the current Chair of the SNIA Technical Council (TC). Mark has been a SNIA member and volunteer for over 18 years, and also wears many other SNIA hats.   Recently, SNIA on Storage sat down with Mark to discuss his first nine months as the TC Chair and his views on the industry.

    SNIA on Storage (SoS):  Within SNIA, what is the most important activity of the SNIA Technical Council?

    Mark Carlson (MC): The SNIA Technical Council works to coordinate and approve the technical work going on within SNIA. This includes both SNIA Architecture (standards) and SNIA Software. The  work is conducted within 13 SNIA Technical Work Groups (TWGs).  The members of the TC are elected from the voting companies of SNIA, and the Council also includes appointed members and advisors as well as SNIA regional affiliate advisors. SNIA_Technology_Infographic_4

    SoS:  What has been your focus this first nine months of 2016?   

    MC: The SNIA Technical Council has overseen a major effort to integrate a new standard organization into SNIA.  The creation of the new SNIA SFF Technology Affiliate (TA) Technical Work Group has brought in a very successful group of folks and standards related to storage connectors and transceivers. This work group, formed in June 2016, carries forth the longstanding SFF Committee work efforts that has operated since 1990 until mid-2016.  In 2016, SFF Committee leaders transitioned the organizational stewardship to SNIA, to operate under a special membership class named Technology Affiliate, while retaining the long standing technical focus on specifications in a similar fashion as all SNIA TWGs do.

    SoS:  What changes did SNIA implement to form the new Technology Affiliate membership class and why?

    MC: The SNIA Policy and Procedures were changed to account for this new type of membership.  Companies can now join an Affiliate TWG without having to join SNIA as a US member.  Current SNIA members who want to participate in a Technology Affiliate like SFF can join a Technology Affiliate and pay the separate dues.  The SFF was a catalyst – we saw an organization looking for a new home as its membership evolved and its leadership transitioned.  They felt SNIA could be this home but we needed to complete some activities to make it easier for them to seamlessly continue their work.   The SFF is now fully active within SNIA and also working closely with T10 and T11, groups that SNIA members have long participated in.

    SoS:  Is forming this Technology Affiliate a one-time activity?

    MC: Definitely not.  The SNIA is actively seeking organizations who are looking for a structure that SNIA provides with IP policies, established infrastructure to conduct their work, and 160+ leading companies with volunteers who know storage and networking technology.

    SoC:  What are some of the customer pain points you see in the industry?

    MC: Critical pain points the TC has started to address with new TWGs over the last 24 months include: performance of solid state storage arrays, where the SNIA Solid State Storage Systems (S4) TWG is working to identify, develop, and coordinate system performance standards for solid state storage systems; and object drives, where work is being done by the Object Drive TWG to identify, develop, and coordinate standards for object drives operating as storage nodes in scale out storage solutions.  With the number of different future disk drive interfaces emerging that add value from external storage to in-storage compute, we want to make sure they can be managed at scale and are interoperable.TC org chart 2016

    SoS:  What’s upcoming for the next six months?

    MC: The TC is currently working on a white paper to address data center drive requirements and the features and existing interface standards that satisfy some of those requirements.  Of course, not all the solutions to these requirements will come from SNIA, but we think SNIA is in a unique position to bring in the data center customers that need these new features and work with the drive vendors to prototype solutions that then make their way into other standards efforts.  Features that are targeted at the NVM Express, T10, and T13 committees would be coordinated with these customers.

    SoS:  Can non-members get involved with SNIA?

    MC:   Until very recently, if a company wanted to contribute to a software project within SNIA, they had to become a member. This was limiting to the community, and cut off contributions from those who were using the code, so SNIA has developed a convenient Contributor License Agreement (CLA) for contributions to individual projects.  This allows external contributions but does not change the software licensing. The CLA is compatible with the IP protections that the SNIA IP Policy provides to our members.  Our hope is that this will create a broader community of contributors to a more open SNIA, and facilitate open source project development even more.

    SoS:  Will you be onsite for the upcoming SNIA Storage Developer Conference (SDC)?

    MC: Absolutely!  I look forward to meeting SNIA members and colleagues September 19-22 at the Hyatt Regency Santa Clara.  We have a great agenda, now online, that the TC has developed for this, our 18th conference, and registration is now open.  SDC brings in more than 400 of the leading storage software and hardware developers, storage product and solution architects, product managers, storage product quality assurance engineers, product line CTOs, storage product customer support engineers, and in–house IT development staff from around the world.  If technical professionals are not familiar with the education and knowledge that SDC can provide, a great way to get a taste is to check out the SDC Podcasts now posted, and the new ones that will appear leading up to SDC 2016.
