3.1.16 LSISAS9218-8i HBA Characteristics
3.1.16.1 Memory
The LSISAS9218-8i HBA provides one 4 M × 16-bit Flash ROM for storing the firmware and BIOS. The LSISAS9218-8i
HBA can provide up to 32 K × 8-bit NVSRAM for storing the nonvolatile RAID information when a system failure occurs
3.1.16.2 LED
The LSISAS9218-8i HBA heartbeat LED, CR1, blinks green to indicate that the HBA is capable of general activity.
3.1.16.3 Connectors
This section describes the different connectors on the LSISAS9218-8i HBA. See Figure 17 for connector locations.
PCIe Connector (EC1). The LSISAS9218-8i 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/SATA Connectors (J5 and J6). The LSISAS9218-8i HBA supports SAS/SATA connections through connectors J5
and J6, which are SFF-8087 mini-SAS, internal connectors. The HBA supports SAS sideband signal assignments.
UART Connector (J1). The UART connector debug port requires a special cable and LSI support to gather detailed
IOC status.
