Features

This section lists features of the LSI PCIe to SAS host adapters:

Supports narrow port and wide port as shown in

Table 1.2

.

Supports SSP, STP, and SMP as defined in the Serial Attached SCSI
(SAS) Specification,
version 1.0.

Supports SATA as defined in the Serial ATA Specification, version
1.0a.

Provides configurable drive spin-up sequencing on a per-phy basis.

Simplifies cabling with a point-to-point, serial architecture.

Provides smaller and thinner cables that do not restrict airflow.

Provides a serial, point-to-point, enterprise-level storage interface.

Transfers data using SCSI information units.

Provides two LEDs for each phy to indicate link activity and faults for
the LSISAS3041E, LSISAS3041EL, LSISAS3080E, LSISAS3080EL,
LSISAS3081E, LSISAS3081EL, LSISAS3442E, LSISAS3442EL,
LSISAS3443E, LSISAS3443EL, LSISAS3444E, LSISAS3444EL,
LSISAS3800E, LSISAS3801E, and LSISAS3801EL host board
adapters (HBAs).

Provides two light pipes routed through the PCI bracket for the
LSISAS3041E, LSISAS3041EL, LSISAS3080E, LSISAS3080EL,
LSISAS3081E, LSISAS3081EL, LSISAS3442E, LSISAS3442EL,
LSISAS3443E, LSISAS3443EL, LSISAS3444E, LSISAS3444EL, and
LSISAS3800E host adapters. One light pipe indicates activity on any
phy. The other light pipe indicates a heartbeat or a fault condition.
The LSISAS3801E and LSISAS3801EL use two LEDs routed
through the PCI bracket for the same purpose.

Provides compatibility with SATA target devices.
