LSISAS9217-4i4e HBA Characteristics
3.1.15.1
Memory
The LSISAS9217-4i4e HBA provides one 4-M × 16-bit Flash ROM for storing the firmware and BIOS. The
LSISAS9217-4i4e HBA can provide up to 32 K × 8-bit NVSRAM for storing the nonvolatile RAID information when a
system failure occurs.
3.1.15.2
LED
The LSISAS9217-4i4e HBA heartbeat LED, CR1, blinks green to indicate that the HBA is capable of general activity.
3.1.15.3
Connectors
This section describes the different connectors on the LSISAS9217-4i4e HBA.
PCIe Connector (EC1). The LSISAS9217-4i4e HBA supports a x8 interface. The PCIe host interface connection is
through the edge connector (EC1) which provides connections on both the top (EC1B) and bottom (EC1A) of the
board. The signal definitions and pin numbers conform to the PCIe specification.
SAS Connector (J6 and J7). The LSISAS9217-4i4e HBA supports SAS connections through connector J6, which is an
SFF-8088 mini-SAS, external, right-angle connector, and connector J7 which is an SFF-8087 internal mini-SAS
connector. The HBA supports SAS sideband signal assignments.
UART Connector (J5). The UART connector debug port requires a special cable and LSI support to gather detailed
IOC status.
