Technical Product Specification

Intel® Server System SR1600UR TPS Hard Disk Drive Support

Revision 1.8 Intel order number E45725-010

Each of the four SAS PHYs on the LSISAS1064E is capable of SAS/SATA link rates of 3.0

Gb/s and 1.5 Gb/s. The user can configure ports as wide or narrow. Narrow ports have one

PHY per port. Wide ports have two, three, or four PHYs per port. Each port supports the SSP,

SMP, STP, and SATA protocols.

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 the Serial ATA technology.

The LSISAS1064E supports the Intel

Embedded RAID Technology II solution, which is a

highly integrated, low-cost software RAID implementation capable of supporting the following

RAID levels: 0, 1, and 10. RAID level 5 is supported with the addition of an optional RAID

Activation Key (Product Order Code – AXXRAKSW5).

The runtime operation of the integrated

RAID solution is transparent to the operating system. A single firmware build supports all

integrated RAID capabilities.

For non-RAID SAS configurations, the LSISAS1064E uses the Fusion-MPT* (Message Passing

Technology) 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, easily developed

device drivers that are independent of the I/O bus. LSI Corporation provides these

device drivers.
