IBM BladeCenter HS23E 17
Internal tape drives
The server does not support an internal tape drive. However, it can be attached to the external tape drives
using SAS or Fibre Channel connectivity (see Table 25).
Optical drives
The server does not support an optical drive option. However, it does interface to the optical drive
installed in the BladeCenter chassis media tray if one is installed there.
I/O expansion options
The HS23E 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 HS23E optionally supports the PCI Express Gen 2 Expansion Blade II listed in Table 11. The
expansion blade provides the capability to attach selected PCI Express cards to the HS23E. 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 2.0 x16 (x8-wired) slot and one full-height and half-length PCI Express 2.0 x16
(x8-wired) 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
HS23E. Each expansion blade occupies a bay in the BladeCenter chassis.

68Y7484 A247 IBM BladeCenter PCI Express Gen 2 Expansion Blade II 4
The HS23E server optionally supports GPU Expansion Blade II expansion units listed in Table 12. 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.
