IBM BladeCenter HS23 17

The HS23 optionally supports the PCI Express Gen 2 Expansion Blade II listed in Table 10.

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. 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 listed in Table 11. 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. Each expansion blade occupies a bay in the BladeCenter

chassis.

Network adapters

The HS23 offers two integrated Gigabit Ethernet ports and two integrated 10 Gb Ethernet ports with the

integrated Emulex BladeEngine 3 (BE3) controller. Two Gigabit Ethernet ports are routed to the chassis

I/O bays 1 and 2 (BladeCenter E, H or HT), and two 10 Gb Ethernet ports are routed to the chassis I/O

bays 7 and 9 using either 10Gb LOM Interposer Card or Emulex Virtual Fabric Adapter II for HS23

(BladeCenter H or HT). With BladeCenter S, both GbE ports are routed to the chassis I/O bay 1.
