N2115 SAS/SATA HBA for IBM System x Characteristics
5.3
Physical Characteristics
The HBA is a 152.4-mm x 64.5-mm (6.0-in. x 2.54-in.), low-profile board. The component height on the top and bottom
of the HBA is in accordance with the PCIe specification. The following figure shows the board layout.

Connectors
This section describes the different connectors on the HBA.
PCIe Connector (EC1).
The HBA supports a x8 interface. The PCIe 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 Connectors (J5 and J6).
The HBA supports SAS connections through connectors J5 and J6, which are SFF-8087
mini-SAS, internal connectors. The HBA supports SAS sideband signal assignments.

Power
Requirements
The maximum power requirements for the HBA under normal operation are as follows:
PCIe 12.0 V = 1.3 A
Power
—
Nominal = 9.8 W
