Standard (T10/SFF) working group and offers
one of the broadest product lines to support
the emerging market for SAS applications.
Serial Attached SCSI (SAS)
was developed to address anticipated I/O and
direct attach storage requirements in the
It provides universal interconnect
with SATA, while offering logical SCSI
compatibility along with SCSI reliability,
performance and manageability.
SAS is a
point-to-point architecture, distinct from
parallel technologies such as Fibre Channel
and SCSI. A point-to-point architecture
establishes a link directly from the
controller to a disk drive or through an
expander switching matrix.
SAS complements SATA by adding
dual porting, full duplex, device addressing and
it offers higher reliability, performance and
data availability services, as well as logical
SCSI compatibility. SAS customers can choose to
deploy cost-effective SATA drives in a SAS
