Scaling Enterprise Storage with SAS Hard Drives
Whitepaper | November 2007 Scaling Enterprise Storage with SAS Hard Drives Introduction Data center workloads have increased exponentially in recent years, requiring IT managers to find new ways of scaling their enterprise storage resources in a way that is both highly reliable and cost-effective. With the introduction of complementary serial interface technologies, IT managers now have the flexibility to deploy either high performance SAS drives or cost-effective Serial ATA (SATA) drives in a Serial Attached SCSI (SAS) storage environment. Hardware compatibility between the new interfaces will provide unprecedented design flexibility for server and storage subsystem deployments. SAS was designed to be the successor to parallel SCSI, which has been used effectively as an enterprise storage interface for more than 20 years. SAS supports the SCSI com- mand set and protocol, maintaining compatibility with the last 20 years of application software investment. SAS will support faster data transfer rates and more devices per controller, as well as reduce the size and complexity of the cables and connectors (thus enabling smaller, more densely-packed disk arrays). SAS is a point-to-point serial architecture, meaning that each drive has a dedicated connection to the host. Eliminating the shared (parallel) bus bottleneck results in higher overall performance because the host will deliver full bandwidth to each individual hard drive. These dedicated, point-to-point connections provide full-duplex connectivity at 3Gb/s for superior performance. SAS is a dual-port interface that provides two separate data paths into the drive. This delivers higher levels of performance and eliminates the “single point of failure” that is a drawback of the current parallel SCSI inter- face. -

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). -

A KVM switch is a hardware device that allows you to use a single keyboard, monitor, and mouse to control multiple computers. Any computer connected to the KVM switch can be easily accessed by either pressing a button on the KVM switch or using a keystroke combination on your keyboard (“Hot-Keys”). LCD Monitor Mouse Keyboard Depending on the number of ports of the selected KVM switch, you can control from 2 to 16 computers. Other enterprise KVM switches allow you to combine or “stack” KVM switches together to control from 128 to 256 computers. There are also audio-rich KVM solutions that offer digital playback and recording, and video-enhanced KVM switches that display crisp, digital images. An essential function of all KVM switches is to properly emulate a keyboard and mouse so that the operating system functions properly. Good KVM switches use microprocessors to emulate keyboard, mouse, and monitor hardware while mechanical KVM switches cannot emulate peripherals. Some computers will not boot if a keyboard is not found (unless you modify a BIOS setting). For Windows users, if a mouse is not detected during startup, a pointer is never displayed. Software alternatives such as PC Anywhere imitate KVM switches by allowing you to switch and forward input over network connections. This has the advantage of reducing the number of wires needed to control multiple computers. -
