  • 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).

  • Using TCP/IP Traffic Shaping to Achieve Iscsi Service Predictability
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by NORA - Norwegian Open Research Archives UNIVERSITY OF OSLO Department of Informatics Using TCP/IP traffic shaping to achieve iSCSI service predictability Master thesis Jarle Bjørgeengen Oslo University College Oslo University/USIT May 26, 2010 Abstract This thesis reproduces the properties of load interference common in many storage devices using resource sharing for flexibility and maximum hardware utilization. The nature of resource sharing and load is studied and compared to assumptions and models used in previous work. The results are used to de- sign a method for throttling iSCSI initiators, attached to an iSCSI target server, using a packet delay module in Linux Traffic Control. The packet delay throttle enables close-to-linear rate reduction for both read and write operations. Ipt- ables and Ipset are used to add dynamic packet matching needed for rapidly changing throttling values. All throttling is achieved without triggering TCP retransmit timeout and subsequent slow start caused by packet loss. A control mechanism for dynamically adapting throttling values to rapidly changing workloads is implemented using a modified proportional integral derivative (PID) controller. Using experiments, control engineering filtering techniques and results from previous research, a suitable per resource saturation indicator was found. The indicator is an exponential moving average of the wait time of active resource consumers. It is used as input value to the PID controller man- aging the packet rates of resource consumers, creating a closed control loop managed by the PID controller. Finally a prototype of an autonomic resource prioritization framework is designed.
