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). -

WHITE PAPER Better Performance, Better Insight for Your Mainframe Storage Network with Brocade Gen 6 TABLE OF CONTENTS Brocade and the IBM z Systems IO product team share a unique Overview .............................................................. 1 history of technical development, which has produced the world’s most Technology Highlights .................................. 2 advanced mainframe computing and storage systems. 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. These technologies leverage the integrity of those products. Driving these fundamental capabilities of Gen 5 and efforts are the deep technical relationships Gen 6 Fibre Channel, and extend them to between the Brocade and IBM z Systems the applications driving the world’s most IO architecture and development teams, critical systems. -

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. -
