firmware. The PCI-X to 3.0 Gbit/s SAS host adapters provide up to 32 K
x 8-bit of a NVSRAM device for storing the nonvolatile RAID information
when a system failure happens.
3.1.1 LSISAS3041X and LSISAS3041XL Host Adapters Characteristics
The LSISAS3041X and LSISAS3041XL are the same HBA with the
exception of the PCI bracket. The LSISAS3041X uses a standard PCI
bracket and the LSISAS3041XL uses the low-profile (LPPCI) PCI
bracket.
Figure 3.1 shows the HBAs and their brackets.
3.1.1.1 LEDs
The LSISAS3041X and LSISAS3041XL host adapters have four LEDs
that turn green to indicate an activity condition on any of the four phys.
There are four LEDs that turn yellow to indicate a fault condition on any
of the four phys. See
Figure 3.1 for LED locations. There is one LED that
flashes green to indicate the LSISAS1064 heartbeat.
3.1.1.2 Connectors
This section provides a description of the five different connectors on the
LSISAS3041X and LSISAS3041XL host adapters. See
Figure 3.1 for
connector locations.
PCI/PCI-X Connector (J1) – The PCI/PCI-X interface operates as a
32-bit or 64-bit DMA bus master. The connection is made through the
edge connector J1, which is a +3.3 V type board edge connector. The
signal definitions and pin numbers conform to the PCI/PCI-X
specifications.
SAS/SATA Connectors (J2–J5) – The LSISAS3041X supports
SAS/SATA connections through connectors J2, J3, J4, and J5. These
connectors are SATA internal right-angle connectors.
