1. Introduction
This section presents a brief overview of the 12/16 bays external Fi-
bre/SAS/iSCSI to 6Gb/s SAS RAID subsystem.
1.1 Overview
SAS 2.0 builds on parallel SCSI by providing higher performance,
improving data availability, and simplifying system design. The SAS
2.0 interface supports both 6Gb/s SAS disk drives for data-inten-
sive applications and 6Gb/s Serial ATA (SATA) drives for low-cost
bulk storage of reference data. The Fibre/SAS/iSCSI to 6Gb/s SAS
RAID controllers attach directly to SATA/SAS midplanes with 3 x
Z-PACK HM-Zd high speed connectors or increase capacity using
one additional SFF-8088 external connector. When used with SAS
expanders, the controller can provide up to (122) devices through
one or more SAS JBODs, making it an ideal solution for enterprise-
class storage applications that called for maximum conguration
exibility.
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem provides three
kinds of host interface link to the host board on the server sys-
tem. This subsystem utilizes the same RAID kernel that has been
eld-proven in existing internal/external SATA/SAS RAID controller
products, allowing to bring stable and reliable SAS RAID external
subsystem.
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem provides a
2U/3U rack-mounted external storage chassis capable of accommo-
dating up to 12/16 6.0-Gb/s, Serial-Attached SCSI (SAS) drives or
6.0-Gb/s Serial ATA (SATA) drives. The redundant controller model
provides fault-tolerant links across separate host interface, while
the single controller model provides a single, straight-through data
path.
Unparalleled Performance
The high speed host interfaces make Fibre/SAS/iSCSI to 6Gb/s
SAS RAID subsystem well suited for professionals who need large
capacity and exceptional performance with connectivity. The Fibre/
