I/O expansion options
The HS22 server offers the following PCI Express 2.0 slots, neither of which is hot-swap.
CIOv expansion slot
CFFh expansion slot
The CIOv I/O expansion connector provides I/O connections through the midplane of the chassis to
modules located in bays 3 and 4 of a supported BladeCenter chassis. It is a PCIe 2.0 x8 slot.
The CFFh I/O expansion connector provides I/O connections to high-speed switch modules that are
located in bays 7, 8, 9, and 10 of a BladeCenter H or BladeCenter HT chassis, or to switch bay 2 in a
BladeCenter S chassis. The CFFh slot is a PCIe x16 slot.
The HS22 optionally supports the IBM BladeCenter PCIe Gen 2 Expansion Blade. The expansion blade
provides the capability to attach selected PCI Express cards to the HS22. This capability is ideal for many
applications that require special telecommunications network interfaces or hardware acceleration using a
PCI Express card.
The expansion blade provides one full height and full length PCI Express slot and one full height and half
length PCI Express slot with a maximum power usage of 75 watts for each slot. It integrates PCI Express
card support capability into the BladeCenter architecture. Up to four expansion blades can be attached to
an HS22. Each expansion blade occupies a bay in the BladeCenter chassis.
The server also supports IBM BladeCenter PCI Express I/O Expansion Unit (PCI Express Gen 1). A
maximum of one unit can be attached to a single blade.
