    Latency Budgets for Solid State Storage Access

    Posted by J Metz

    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.
