What Is It and How We Use It
Infiniband Overview What is it and how we use it What is Infiniband • Infiniband is a contraction of "Infinite Bandwidth" o can keep bundling links so there is no theoretical limit o Target design goal is to always be faster than the PCI bus. • Infiniband should not be the bottleneck. • Credit based flow control o data is never sent if receiver can not guarantee sufficient buffering What is Infiniband • Infiniband is a switched fabric network o low latency o high throughput o failover • Superset of VIA (Virtual Interface Architecture) o Infiniband o RoCE (RDMA over Converged Ethernet) o iWarp (Internet Wide Area RDMA Protocol) What is Infiniband • Serial traffic is split into incoming and outgoing relative to any port • Currently 5 data rates o Single Data Rate (SDR), 2.5Gbps o Double Data Rate (DDR), 5 Gbps o Quadruple Data Rate (QDR), 10 Gbps o Fourteen Data Rate (FDR), 14.0625 Gbps o Enhanced Data Rate (EDR) 25.78125 Gbps • Links can be bonded together, 1x, 4x, 8x and 12x HDR - High Data Rate NDR - Next Data Rate Infiniband Road Map (Infiniband Trade Association) What is Infiniband • SDR, DDR, and QDR use 8B/10B encoding o 10 bits carry 8 bits of data o data rate is 80% of signal rate • FDR and EDR use 64B/66B encoding o 66 bits carry 64 bits of data Signal Rate Latency SDR 200ns DDR 140ns QDR 100ns Hardware 2 Hardware vendors • Mellanox o bought Voltaire • Intel o bought Qlogic Infiniband business unit Need to standardize hardware. Mellanox and Qlogic cards work in different ways. -
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). -

Parallel ATA has maintained its success for many years for three primary reasons: 1) Low Cost, 2) virtually universal operating system support, and 3) the ability to evolve to higher speeds and performance whilst maintaining backwards compatibility with older parallel ATA devices. From its original interface speed of just 3MB/s, parallel ATA has moved up to burst transfer rates of 66MB/s and 100MB/s and beyond. The latest generation of the parallel ATA interface, Ultra ATA-133, goes even further with a burst transfer rate of up to 133MB/s. While parallel ATA has enjoyed an illustrious track record, the specification is now showing its age. Parallel ATA imposes some serious design issues on today’s developers, including a 5 volt signaling requirement, high pin count, major cabling headaches and, perhaps most significantly, limited performance headroom. -

SATA Express
1-512-256-0197 www.mindshare.com [email protected] SATA Express Let MindShare Bring “SATA Express” to Life for You MindShare brings the SATA Express course to life through its interactive classroom style and demonstrations. SATA Express bus interface supports both Serial ATA (SATA) and PCI Express (PCIe) storage devices, initially standardized in the SATA 3.2 specification. The SATA Express connector used on the host side is backward compatible with the standard SATA data connector. It also provides multiple PCI Express lanes as a pure PCI Express connection to the storage device. Three options are available for connection of storage devices, 1) Legacy SATA, 2) SATA Express using AHCI, 3) SATA Express using NVMe. This course assumes the student is familiar with both SATA and PCI Express protocol. The course focuses on connector and cable architecture as well as M.2 Device architecture. The course then covers the architecture of both AHCI and NVMe host controllers associated with SATA and PCIe connected storage devices. You Will Learn: • SATA Express connector and cable structure • M.2 devices and sockets/cards • Pertinent AHCI controller and commands • Pertinent NVMe controller and commands • Interrupt handling • Error handling • Power management Course Length: 2 Days Who Should Attend? Hardware designers, software developers, and system validation engineers will all benefit from this course. Both hardware and software requirements of a SATA Express subsystem are detailed and explained through numerous examples. Course Contents: -
