IBM BladeCenter HS23 14
I/O expansion options
The HS23 server offers the following PCI Express 3.0 slots:
CIOv expansion slot: PCIe 3.0 x8

CFFh expansion slot: PCIe 3.0 x16

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. 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 HS23 optionally supports the PCI Express Gen 2 Expansion Blade II. The expansion blade provides
the capability to attach selected PCI Express cards to the HS23. This capability is ideal for many
applications that require special telecommunications network interfaces or hardware acceleration using a
PCI Express card (Table 10).
The expansion blade provides one full-height and full-length PCI Express x16 (x8-wired) Gen 2 slot and
one full-height and half-length PCI Express x16 (x8-wired) Gen 2 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 HS23. Each expansion blade occupies a bay in the
BladeCenter chassis.

The HS23 server optionally supports GPU Expansion Blade expansion units. This capability is ideal for
many applications written to take advantage of acceleration and visualization performance advantages
that are offered in general-purpose computing on GPUs. This product ships integrated with one NVIDIA
Tesla M2090, one NVIDIA Tesla M2075, or one NVIDIA Tesla M2070Q GPU.
The stacking capability of the IBM BladeCenter GPU Expansion Blade II allows you to connect up to four
of them to a single blade server. In addition, you can still use a CFFh I/O expansion card adapter by
installing it in the top-most expansion blade.
Table 11 lists the ordering information for the IBM BladeCenter GPU Expansion Blade II variants.
