IBM BladeCenter HS22V 11
I/O expansion options
The HS22V server offers the following PCI Express 2.0 slots. Neither are 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 HS22V optionally supports the IBM BladeCenter PCI Express I/O Expansion Unit (PCI Express Gen
1). The expansion blade provides the capability to attach selected PCI Express cards to the HS22V. This
capability is ideal for many applications that require special telecommunications network interfaces or
hardware acceleration using a PCI Express card.
The IBM BladeCenter PCI Express I/O Expansion Unit has two standard full-length PCI Express slots that
support the attachment of two full sized, 25 W PCI Express adapters. These two slots are PCI Express
x16 slots mechanically, however they can operate only at speeds up to x8. The unit provides two power
connectors that can be used to provide 12V, with a cable, to PCI Express adapters that have external
power connectors. One expansion blade can be attached to an HS22V. Each expansion blade occupies a
bay in the BladeCenter chassis. See the following table.
