  • 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).

Brocade’s Gen 6 Fibre Channel Technology technical heritage can be traced to the late 1980s, with the creation of Benefits for z Systems and Flash channel extension technologies to extend data centers beyond the “glass- Storage ................................................................ 7 house.” IBM revolutionized the classic “computer room” with the invention Summary ............................................................. 9 of the original ESCON Storage Area Network (SAN) of the 1990s, and, in the 2000s, it facilitated geographically dispersed FICON® storage systems. Today, the most compelling innovations in mainframe storage networking technology are the product of this nearly 30-year partnership between Brocade and IBM z Systems. As the flash era of the 2010s disrupts between the business teams allows both the traditional mainframe storage organizations to guide the introduction networking mindset, Brocade and of key technologies to the market place, IBM have released a series of features while the integration between the system that address the demands of the data test and qualification teams ensures the center.

  • Serial Attached SCSI (SAS)
    Storage A New Technology Hits the Enterprise Market: Serial Attached SCSI (SAS) A New Interface Technology Addresses New Requirements Enterprise data access and transfer demands are no longer driven by advances in CPU processing power alone. Beyond the sheer volume of data, information routinely consists of rich content that increases the need for capacity. High-speed networks have increased the velocity of data center activity. Networked applications have increased the rate of transactions. Serial Attached SCSI (SAS) addresses the technical requirements for performance and availability in these more I/O-intensive, mission-critical environments. Still, IT managers are pressed on the other side by cost constraints and the need White paper for flexibility and scalability in their systems. While application requirements are the first measure of a storage technology, systems based on SAS deliver on this second front as well. Because SAS is software compatible with Parallel SCSI and is interoperable with Serial ATA (SATA), SAS technology offers the ability to manage costs by staging deployment and fine-tuning a data center’s storage configuration on an ongoing basis. When presented in a small form factor (SFF) 2.5” hard disk drive, SAS even addresses the increasingly important facility considerations of space, heat, and power consumption in the data center. The backplanes, enclosures and cabling are less cumbersome than before. Connectors are smaller, cables are thinner and easier to route impeding less airflow, and both SAS and SATA HDDs can share a common backplane. White paper Getting this new technology to the market in a workable, compatible fashion takes various companies coming together.

  • Chapter 6 MIDI, SCSI, and Sample Dumps
    MIDI, SCSI, and Sample Dumps SCSI Guidelines Chapter 6 MIDI, SCSI, and Sample Dumps SCSI Guidelines The following sections contain information on using SCSI with the K2600, as well as speciÞc sections dealing with the Mac and the K2600. Disk Size Restrictions The K2600 accepts hard disks with up to 2 gigabytes of storage capacity. If you attach an unformatted disk that is larger than 2 gigabytes, the K2600 will still be able to format it, but only as a 2 gigabyte disk. If you attach a formatted disk larger than 2 gigabytes, the K2600 will not be able to work with it; you could reformat the disk, but thisÑof courseÑwould erase the disk entirely. Configuring a SCSI Chain Here are some basic guidelines to follow when conÞguring a SCSI chain: 1. According to the SCSI SpeciÞcation, the maximum SCSI cable length is 6 meters (19.69 feet). You should limit the total length of all SCSI cables connecting external SCSI devices with Kurzweil products to 17 feet (5.2 meters). To calculate the total SCSI cable length, add the lengths of all SCSI cables, plus eight inches for every external SCSI device connected. No single cable length in the chain should exceed eight feet. 2. The Þrst and last devices in the chain must be terminated. There is a single exception to this rule, however. A K2600 with an internal hard drive and no external SCSI devices attached should have its termination disabled. If you later add an external device to the K2600Õs SCSI chain, you must enable the K2600Õs termination at that time.
