  • Proposal Regarding USENIX and Openfabrics Alliance Ellie Young, 9/18/2008
    Proposal Regarding USENIX and OpenFabrics Alliance Ellie Young, 9/18/2008 For the past two months a group from the OpenFabrics Alliance and USENIX management have been working together to reach an agreement on how best to explore the feasibility and desirability of OFA and USENIX combining forces in a way that would work to the advantage of both organizations. Now the USENIX Board must decide whether we should take the next step: sending a MOU to provide services to OFA as a 501(c)(6) under our 501(c)(3). We realized last week that in order for us to announce this at the obvious juncture, the upcoming Supercomputing Conference in November, we need to have a decision from OFA by September 29. In the past month USENIX has been given a consulting membership in OFA. Some of us have been participating in marketing, legal, and executive working group meetings. I think we have now spent enough time "getting to know one another." Background Last year, in response to the Board's request that we reach out to open source software projects and look beyond the academic and research community we currently serve, Clem Cole introduced us to several members of the OpenFabrics Alliance. We made a proposal to organize their annual Sonoma Workshop this past spring, but they decided to continue organizing this year’s event on their own. We were contacted again this summer. At a meeting in August, part of which Matt Blaze attended, we discussed the current state of OFA. Our notes on that meeting include: Software development: Development is the most valuable activity for OFA, but it's on its own track (Sonoma workshops, as well as workshops alongside Supercomputing, although there were none this year) and goes pretty smoothly for two software releases per year.

  • NVM Express Over Fabrics
    NVM Express Over Fabrics Dave Minturn, Intel Corp. OFADevWorkshop NVMe in Fabric Environments • A primary use case for NVMe PCIe SSDs is in an all flash appliance • Hundreds or more SSDs may be attached – too many for PCIe based attach scale-out • Concern: Today remote SSD scale-out over a fabric attach uses SCSI based protocols: Requiring protocol translation Desire best performance and latency from NVMe SSD investment over fabrics like Ethernet with RDMA (iWARP,RoCE), InfiniBand™, and Intel® Omni-Path Architecture Realizing Benefit of Next Gen NVM over Fabrics • PCIe NVMe SSD latency may be < 10 µs with Next Generation NVM • Using a SCSI-based protocol for remote NVMe access ads over 100 µs* in latency • Usage models require efficient write mirroring of PCIe Next Gen NVMe SSDs over fabrics *Source: Intel measurements. Concern: Low latency of Next Gen NVM lost in (SCSI) translation. Why NVMe over Fabrics? Simplicity, Efficiency and End-to-End NVMe Model • Simplicity of protocol enables hardware automated I/O Queues – NVMe transport bridge • No translation to or from another protocol like SCSI (in firmware/software) • Inherent parallelism of NVMe multiple I/O Queues is exposed to the host • NVMe commands and structures are transferred end-to-end • Maintains the NVMe architecture across a range of fabric types • Maintains architecture and software consistency between fabric types by standardizing a common abstraction and encapsulation definition Performance Goal: Make remote NVMe access over fabrics equivalent to local PCIe attached NVMe,
