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: -

Companies looking to invest in their data massive secondary storage in the same For data centers built on parallel SCSI, center today have four technologies from storage system, connected to the same SAS provides the added benefit of being which to choose: Parallel SCSI, Fibre controller as the SAS drives. Because SAS able to easily evolve to a new technology. Channel, Serial ATA (SATA), and Serial controllers support scalability to 256 Simply installing a SAS controller in the Attached SCSI (SAS). Parallel SCSI and devices using SAS expanders, storage can same box as the parallel SCSI controller, Fibre Channel have long been the gold be expanded to tens of terabytes using one allows the company to take advantage of standard in performance for mission- controller, no matter which types of disks all the benefits of SAS without scrapping critical data; however, with the industry or devices are connected to it. the legacy SCSI investment. transition from parallel to serial, Parallel Systems Integrators also gain ROI from SCSI is on the decline, and Fibre channel choosing SAS, which enables them to has some significant drawbacks that have build most of their solutions using a single limited its deployment. Start with the type of components. There is less huge initial capital cost of installing a inventory to stock and fewer technologies completely separate Fibre Channel to support, so overhead is reduced. Plus, infrastructure. Then, there is the high they gain the ability to migrate customers price tag of Fibre Channel disks each time as their needs change simply by swapping capacity must be added and also the cost disks, making it easier to keep installed of having a Fibre Channel expert on staff.
