SAS Storage Architecture: Serial Attached SCSI, 2005, Mike Jackson, 0977087808, 9780977087808, MindShare Press, 2005 DOWNLOAD http://bit.ly/1zNQCoA http://www.barnesandnoble.com/s/?store=book&keyword=SAS+Storage+Architecture%3A+Serial+Attached+SCSI SAS (Serial Attached SCSI) is the serial storage interface that has been designed to replace and upgrade SCSI, by far the most popular storage interface for high-performance systems for many years. Retaining backward compatibility with the millions of lines of code written to support SCSI devices, SAS incorporates recent advances in high-speed serial design to provide better performance, better reliability and enhanced capabilities, all at a lower cost. SAS will be a significant part of many future high-performance storage systems, and hardware designers, system validation engineers, device driver developers and others working in this area will need a working knowledge of it.SAS Storage Architecture provides a comprehensive guide to the SAS standard. The book contains descriptions and numerous examples of the concepts presented, using the same building block approach as other MindShare offerings. This book details important concepts relating to the design and implementation of storage networks.Specific topics of interest include:SATA Compatibility Expander devices Discovery Process Connection protocols Arbitration of competing connection requests Flow Control protocols ACK/NAK protocol Primitives ? construction and uses Frames ? format, definition, used of each field Error checking mechanisms -

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). -
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, -

General Nvme FAQ
General NVMe FAQ 1. What is NVMe? NVMe, more formally NVM Express, is an interface specification optimized for PCI Express based solid state drives. The interface is defined in a scalable fashion such that it can support the needs of Enterprise and Client in a flexible way. 2. Is NVMe an industry standard? NVM Express has been developed by an industry consortium, the NVM Express Workgroup. Version 1.0 of the interface specification was released on March 1, 2011. Over 80 companies participated in the definition of the interface. 3. What is the legal framework of the NVM Express organization? The legal framework is structured as a Special Interest Group (SIG). To join a company executes a Contributor/Adopter agreement. There are 11 member companies who have board seats and provide overall governance. The Governing board is called the NVM Express Promoters Group. There are seven permanent seats and six seats filled by annual elections. Contributor companies are all free to participate in regularly scheduled workinG sessions that develop the interface. All Contributors have equal input into the development of the specification. 4. Who are the companies that form the NVM Express Promoters Group? The Promoters Group is composed of 13 companies, Cisco, Dell, EMC, IDT, Intel, Marvell, Micron, NetApp, Oracle, Samsung, SanDisk, SandForce (now LSI) and STEC. Two elected seats are currently unfilled. 5. Who are the permanent board members? Cisco, Dell, EMC, IDT, Intel, NetApp, and Oracle hold the seven permanent board seats. 6. How is the specification developed? Can anyone contribute? The specification is developed by the NVM Express Working Group. -
