OVERVIEW
The LSI Logic Serial Attached SCSI (SAS) 3Gb/s integrated controller is
based on Fusion-MPT™ (Message Passing Technology) architecture, the
industry’s leading high-performance interface technology. The LSISAS1068
eight-port controller provides 1.5 and 3Gb/s data transfer rates per port
and enables Integrated RAID solutions in storage environments including
servers and external storage systems. The LSI Logic SAS controller is ideal for
– Backward compatible with

today’s data centers and leverages existing SCSI infrastructure for investment
protection. The serial interface allows for point-to-point connection, increased
I
device bandwidth, higher availability with dual ported drives, and enhanced
I
reliability when compared to parallel SCSI.
LSI Logic SAS controllers comply with the SAS standard which includes
improved performance, simplified cabling, smaller connectors, a lower pin
count, and lower power requirements. The eight-port controller provides an
aggregate bandwidth of 2.4GB/s and also runs in full duplex. In addition,
the LSI Logic SAS controllers leverage an electrical and physical connection
interface that is compatible with Serial ATA technology. This provides
users with unprecedented choices for servers and storage sub-systems.
SAS controllers support command queuing to maximize drive performance.
Interrupt coalescing is another advanced feature of the controllers that
improves system performance by reducing the number of interrupts per I/O
to less than one.
