PCI Interface

Intel

Integrated RAID Module RMS25KB080 and RMS25KB040 must be installed into

a standard x8 or larger PCI Express* slot that complies with the PCI Express

Specification, Revision 3.0. The controller is PCI Express* 1.0 and 2.0 compatible and is

backward-compatible with x8 or larger slots that are wired with x1, x2, and x4 PCI

Express* lanes.

Note: The modules will

support PCI Express* Revision 3.0 at post launch.

Host Board Interface

Intel

Integrated RAID Module RMS25JB080 and RMS25JB040 board interface with the

host system through one custom board-to-board interface that implements one x8 PCI

Express* lanes signaling as defined in the PCI Express Specification 3.0. These interfaces

also provide +3.3 V power to the board.
