LSI SAS 9311-8i PCI Express to 12Gb/s SAS HBA User Guide
December 2013
5.3 Connectors
PCIe Connector (EC1). The LSI 12Gb/s SAS HBA supports a x8 interface. The PCIe host interface connection is through
the edge connector, EC1, which provides connections on both the top (EC1 B) and bottom (EC1 A) of the board. The
signal definitions and pin numbers conform to the PCIe specification.
SATA+SAS Connector (J1). The LSI 12Gb/s SAS HBA supports SATA and SAS connectors through connectors that are
SFF-8643 mini-SAS HD, internal connectors.
5.4 Physical Characteristics
The LSI 12Gb/s SAS HBA is a 6.0-in. × 2.7-in., low-profile board. The component height on the top and bottom of the
LSI 12Gb/s SAS HBA is in accordance with the PCIe specification. The following figure shows the HBA board layout.

 J1 – SFF-8643 mini-SAS HD, internal, right-angle connectors
5.5 Electrical Characteristics
The maximum power requirements for the LSI SAS 9311-8i HBA under normal operation are as follows:
 PCIe 12.0 V = 1.59 A
 Power values
— Nominal = 13.0 W
— Worst case = 19.04 W
