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. -

Assumptions Students have basic knowledge of English language and Computer Hardware A Computre System Requirement Screw Driver Software Nil Requirement Learning Major Learning outcome of this experiment are: Outcome Identifying Ports, Cables and Connectors THEORY Port The Point at which peripheral attaches to. Communicates with a system unit so that peripheral can send data to or receive information from the computer. Following are the different Types of Ports of Computer System. 1) PS/2 Ports The PS/2 Ports are simple, 6-pin, low-speed serial connections commonly dedicated to a keyboard and mouse. Although these ports may look identical at first glance, they are not interchangeable, so you'll need to be extremely careful to attach the keyboard and mouse to their respective PS/2 port. 2) VGA Mointer Port Video Graphics Array: used to connect the monitor to the computer 3) Parallel Port P a g e | 8 Computer maintenance and TROUBLESHOOTING (3350701), Semester – 5th The parallel port originally started out as a unidirectional (output only) Printers and other devices are said to be either parallel or serial. Parallel means the device is capable of receiving more than one bit at a time (that is, it receives several bits in parallel). Most modern printers are parallel. -

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). -

Tighten nut to value on label. attach BD-2HLS to paddle. the BD-2HLS. 847.325.7825 OR VISIT WWW.REMKE.COM/MELNI MELNI BD-2HLS THE SMARTER CRIMPLESS CONNECTOR. Traditional electrical connector methodology is based on crimping, using a device to conjoin two pieces of metal by deforming one or both of them in a way that causes them to hold to each other. This requires multiple lugs and specialized dyes, each one manufactured for a specific cable size. The process is lengthy and intricate, requiring precise tools to secure the connection, such as hydraulic or mechanical crimps that are expensive and hard on the installer’s back and shoulders. Though this practice is time consuming, expensive and hazardous, it has been the accepted process for years. But all it takes is one idea to change everything. Introducing the BD-2HLS Melni Crimpless Connector. The BD-2HLS is a mechanical connector that can replace existing commercial mechanical and crimp-style connectors. Its crimpless installation design and spiral insert technology simplifies the connection process making it safer, easier and less expensive. A revolutionary innovation, the BD-2HLS is redefining the electrical industry. While traditional 2-hole lugs are non-range taking, the Melni BD-2HLS accepts anything between 2/0 AWG and #2AWG, spanning a large range of cable and wire sizes, and drastically reducing installation time. The BD-2HLS is all that’s required for a variety of electrical applications - having multiple lug sizes and specialized dies on hand just isn’t necessary anymore. -
