1.2 Features
This section lists features of the LSI PCIe to SAS HBAs:
• 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 SAS3041E, SAS3041EL, SAS3042E, SAS3042EL,
SAS3080E, SAS3080EL, SAS3081E, SAS3081EL, SAS3442E,
SAS3442EL, SAS3444E, SAS3444EL, SAS3800E, SAS3801E,
SAS3801EL and SAS31601E host board adapters (HBAs).
• Provides two light pipes routed through the PCI bracket for the
SAS3041E, SAS3041EL, SAS3042E, SAS3042EL, SAS3080E,
SAS3080EL, SAS3081E, SAS3081EL, SAS3442E, SAS3442EL,
SAS3444E, SAS3444EL, and SAS3800E HBAs. One light pipe
indicates activity on any PHY. The other light pipe indicates a
heartbeat or a fault condition. The SAS3801E and SAS3801EL use
two LEDs routed through the PCI bracket for the same purpose.
• Provides compatibility with SATA target devices.
