Remarkable Performance with
Advanced SAS/SATA Technology
The LSISAS3081E-R doubles the performance
of today’s dual channel Ultra320 SCSI HBAs by
connecting an 8-lane 2.5Gb/s PCI Express bus
with eight 3Gb/s SAS/SATA ports. It also offers
leading SAS and SATA RAID and non-RAID data
off-load for medium to high-capacity internal
server storage applications. The LSISAS3081E-R
is ideal for today’s data centers and leverages
existing SCSI infrastructure for investment
protection and ease of migration. The serial
interface allows for point-to-point connections
offering higher performance, increased aggregate bandwidth, higher availability with
dual-ported drives, and enhanced reliability when compared to parallel SCSI. The LSI SAS
HBA will support 1.5 and 3Gb/s SAS and SATA
hard disk drives.
The SAS interface provides universal interconnect
with Serial ATA, while still offering logical
SCSI compatibility along with the reliability,
performance and manageability available with
SAS drives. Common electrical and physical
connections allow for the application to dictate
the technology of choice for disk drives.
LSI SAS Outperforms Competition
with Integrated RAID
As the performance leader in SAS controllers, the
LSISAS3081E-R leverages advanced Fusion-MPT architecture that is truly scalable. While other SAS cards drive large RAID software stacks between
the host CPU and controller, the LSISAS3081E-R
HBA utilizes the embedded CPU in the LSISAS1068E ASIC to perform Integrated RAID 0, 1, 1E and 10E operations. The result is an ultra-thin
low-overhead device driver communicating over
the PCI Express host-bus. By reducing RAID code overhead, the LSISAS3081E-R offers the greatest
internal READ/WRITE performance available.
Flexibility From an Internal Storage Array
Flexibility is a key advantage of SAS when
considering compatibility with either SAS or
SATA drives. LSI maximizes flexibility by offering
eight internal SAS/SATA drive connects, allowing
integrators to build large capacity tiered
storage arrays without leaving the server. The
flexibility of eight SAS ports controlling an
internal SAS/SATA drive configuration lowers costs
while providing the necessary performance for
mission critical operations.
