U320 SCSI technology has a higher nominal throughput vs. SAS on a single drive basis, the shared bus
limitation imposes a bottleneck on system performance. The performance scalability of SAS when adding
hard disk drives to a system far exceeds the minimal bandwidth advantage of Parallel SCSI. SAS is therefore
the logical choice if scalability is a key requirement.
AIC and Fujitsu are among the first manufacturers to exploit these new capabilities to their fullest, starting
with the Fujitsu 3 rd generation 3Gb/sec SAS enterprise hard disk drive in a SFF 2.5" canister, model #
XC-28-SA1-2, which can host eight SFF hard disk drives in two standard 5.25" size bays. AIC also has 1U
10x and 2U 24x SFF bay server (Model # RSC-1A-SA1-2 and RSC-2A-SA1-2) while its Xtore business unit
offers the JBOD version (Model #XJ-SA26-110R and XJ-SA26-224R). With smaller form-factor hard disk
drives, a greater number of SAS hard disk drives can be installed in lieu of conventional 3.5" hard disk
drives, thus increasing total capacity and spindle density in the same physical area as well as improving I/O
performance. Everything becomes smaller! The smaller form factor also reduces power consumption and
heat dissipation.
Proven Performance
The current generation of Fujitsu 2.5" SFF SAS hard
disk drives have capacities of 36GB to 147GB,
offered at either 10K (MBB series) or 15K (MBC
series) RPM. They log a mean-time-between-failure
(MTBF) of 1,400,000 power-on hours. The hard disk
drives are hot pluggable, so they can be inserted or
removed without harming the data or the system
while the entire system is still powered on. The
vastly simplified SAS four-wire interconnect also
makes hot plugging easier. The 3Gb/sec SAS
interface of the Fujitsu hard disk drives allows
customers to take advantage of the increased
performance associated with Serial Attached SCSI,
while at the same time providing lower heat
dissipation, lower acoustics and lower power.
As a leader in storage technology globally, Fujitsu has been a leader in development of the SAS standard
and is a member of the SCSI Trade Association.
AIC has been focusing on storage enclosures for the past five years and was one of the first vendors to team
up with Fujitsu to develop 2.5" SFF SAS HD D enclosures. AIC's BR-SAS28 canister enables anyone wishing
to quickly transition to SAS to simply drop this canister into existing deployed servers that have at least two
open 5.25" bays. Self-contained cooling is completely server independent. For anyone with a bigger
appetite, AIC also offers 1U 10xSFF bays as well as 2U 24xSFF bay server enclosures. The JBOD lines with
identical configuration are offered through the Xtore business unit. RAID versions will also be available by
Q2 of 2006. AIC is also a member of SCSI Trade Association.
