  • SAS Enters the Mainstream Although Adoption of Serial Attached SCSI
    SAS enters the mainstream By the InfoStor staff http://www.infostor.com/articles/article_display.cfm?Section=ARTCL&C=Newst&ARTICLE_ID=295373&KEYWORDS=Adaptec&p=23 Although adoption of Serial Attached SCSI (SAS) is still in the infancy stages, the next 12 months bode well for proponents of the relatively new disk drive/array interface. For example, in a recent InfoStor QuickVote reader poll, 27% of the respondents said SAS will account for the majority of their disk drive purchases over the next year, although Serial ATA (SATA) topped the list with 37% of the respondents, followed by Fibre Channel with 32%. Only 4% of the poll respondents cited the aging parallel SCSI interface (see figure). However, surveys of InfoStor’s readers are skewed by the fact that almost half of our readers are in the channel (primarily VARs and systems/storage integrators), and the channel moves faster than end users in terms of adopting (or at least kicking the tires on) new technologies such as serial interfaces. Click here to enlarge image To get a more accurate view of the pace of adoption of serial interfaces such as SAS, consider market research predictions from firms such as Gartner and International Data Corp. (IDC). Yet even in those firms’ predictions, SAS is coming on surprisingly strong, mostly at the expense of its parallel SCSI predecessor. For example, Gartner predicts SAS disk drives will account for 16.4% of all multi-user drive shipments this year and will garner almost 45% of the overall market in 2009 (see figure on p. 18).

Han, [email protected]) 인공지능연구소 책임연구원/연구위원 ABSTRACT High-performance computing (HPC) is the underpinning for many of today’s most exciting new research areas, to name a few, from big science to new ways of fighting the disease, to artificial intelligence (AI), to big data analytics, to quantum computing. This report captures the summary of a 9-day program of presentations, keynotes, and workshops at the SC20 conference, one of the most prominent events on sharing ideas and results in HPC technology R&D. Because of the exceptional situation caused by COVID-19, the conference was held entirely online from 11/9 to 11/19 2020, and interestingly caught more attention on using HPC to make a breakthrough in the area of vaccine and cure for COVID-19. The program brought together 103 papers from 21 countries, along with 163 presentations in 24 workshop sessions. The event has covered several key areas in HPC technology, including new memory hierarchy and interconnects for different accelerators, evaluation of parallel programming models, as well as simulation and modeling in traditional science applications. Notably, there was increasing interest in AI and Big Data analytics as well. With this summary of the recent HPC trend readers may find useful information to guide the R&D directions for challenging new technologies and applications in the area of HPC.

  • 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,
