Specifications of LSISAS1068E

• Lead Free Status / RoHS Status: Not Compliant

The SAS interface uses the proven SCSI command set to ensure reliable
data transfers, while providing the connectivity and flexibility of
point-to-point serial data transfers. The SAS interface provides improved
performance, simplified cabling, smaller connectors, lower pin count, and
lower power requirements when compared to parallel SCSI. SAS
controllers leverage an electrical and physical connection interface that
is compatible with SATA technology.
The LSISAS1068E supports the Integrated RAID solution, which is a
highly integrated, low-cost RAID implementation. It is designed for
systems requiring redundancy and high availability, but not needing a full-
featured RAID implementation. Integrated RAID technology supports up
to two volumes and ten drives. Each volume can contain up to eight
drives. The Integrated RAID solution includes Integrated Mirroring™ (IM)
technology, Integrated Mirroring Enhanced (IME), and Integrated
Striping™ (IS) technology. IM technology provides physical mirroring of
two physical drives, plus a hot spare drive. IME supports three to eight
drives plus a hot spare drive. IM technology and IME require an
NVSRAM to support write journaling. IS technology enables data striping
across up to eight physical drives. The Integrated RAID solution is OS
independent, easy to install and configure, supports up to eight drives at
RAID Level 0, and does not require a special driver. The runtime
operation of the Integrated RAID solution is transparent to the operating
system. A single firmware build supports all Integrated RAID capabilities.
The LSISAS1068E uses the Fusion-MPT architecture, which features a
performance based message passing protocol that offloads the host
CPU by completely managing all I/Os and minimizes system bus
overhead by coalescing interrupts. The proven Fusion-MPT architecture
requires only thin, easy-to-develop device drivers that are independent of
the I/O bus. LSI Logic provides these device drivers.
To meet its flexibility and data transfer requirements, the LSISAS1068E
uses an ARM966 processor that operates at 225 MHz. LSI manufactures
the LSISAS1068E using Gflx™ technology.
