Abstract
The BladeCenter PCI Express Gen 2 Expansion Blade and Expansion Blade II provide the capability to attach selected PCI Express cards on selected server blades. This capability is ideal for many applications that require special telecommunications network interfaces or hardware acceleration using a PCI Express card. They provide one full height, full length PCI Express slot and one full height, half length PCI Express slot with a 75 watt power supply for each slot integrating PCI Express card support capability into the BladeCenter architecture.
Note: These options have been withdrawn from marketing and is no longer available for ordering.
Introduction
The BladeCenter® PCI Express Gen 2 Expansion Blade and Expansion Blade II provide the capability to attach selected PCI Express cards on selected server blades. This capability is ideal for many applications that require special telecommunications network interfaces or hardware acceleration using a PCI Express card. They provide one full height, full length PCI Express slot and one full height, half length PCI Express slot with a 75 watt power supply for each slot integrating PCI Express card support capability into the BladeCenter architecture. Figure 1 shows the BladeCenter PCI Express Gen 2 Expansion Blade attached to an HS22 blade server.

Did you know?
The unique stacking capability of the BladeCenter PCI Express Gen 2 Expansion Blade and Expansion Blade II allow you to connect up to four of them (depending on the attached server) to a single blade server providing up to eight PCIe 2.0 slots. In addition, you can still use a CFFh I/O expansion card adapter by installing it in the top-most expansion blade.

Features
The expansion blades have the following features:
- Support for PCIe 2.0 adapters in an expansion blade
The expansion blade lets you install one or two standard form factor PCIe 2.0 adapter cards in a BladeCenter environment, enabling the use of specialized adapters or adapters that wouldn't otherwise be available to BladeCenter customers. Each of the two adapters can consume up to 75W.
- Ability to stack up to four expansion blades on a single base blade
You can attach up to two, three or four expansion blades (depending on the attached server), thereby maintaining the BladeCenter density advantage while still giving you the option to install PCIe cards as needed without the need for each server blades and the added complexity and cost that brings. The first expansion blade connects to the server blade using the CFFh expansion slot of the server blade. The second expansion blade attaches to the CFFh connector on the first expansion blade, and so on.
- CFFh slot still available
The CFFh expansion connector is accessible on the top-most expansion blade (see Figure 3), even with four expansion blades attached. This lets you maintain the integrated networking capabilities of the blade server when installed in a BladeCenter H or BladeCenter HT chassis.
The layout of the expansion blade is shown in Figure 3.

Specifications
The expansion blades have the following specifications:
- 30 mm expansion blade, attaches to a supported server blade
- Two PCI Express 2.0 slots:
- Each slot x8 electrically, x16 mechanically
- Each slot supports adapters up to 75W power consumption
- Slot 1 supports full-length/full-height cards
- Slot 2 supports half-length/full-height cards
- Supported cards are listed in Table 4.
- Up to four expansion blades can be attached to the base server, depending on the server they are attached to (see Table 2 for supported server and expansion blade combinations):
- HS22: Up to four expansion blades
- HS23: Up to four expansion blades
- Single-node HX5: Up to three expansion blades
- Two-node HX5: Up to two expansion blades
- The CFFh slot remains usable on the top-most expansion blade, for use in BladeCenter H and HT configurations. Supported CFFh cards are listed in Table 5.
Supported servers
The BladeCenter PCI Express Gen 2 Expansion Blade and Expansion Blade II are supported attached to the BladeCenter servers listed in Table 2.

The maximum number of expansion blades that can be attached is as follows:
- HS22: Up to four expansion blades (total width will be 150 mm)
- HS23: Up to four expansion blades (total width will be 150 mm)
- HS23E: Up to four expansion blades (total width will be 150 mm)
- Single-node HX5: Up to three expansion blades (total width will be 120 mm)
- Two-node HX5: Up to two expansion blades (total width will be 120 mm)
The Expansion Blade attaches to the blade server unit through the CFFh connector on the system board of the server blade. The top cover of the blade server needs to be removed and the Expansion Blade attaches to it, forming a double-width blade server unit. Additional PCI Express Gen 2 Expansion Blade can be attached up to the supported maximum for the server type. A supported CFFh adapter can be attached to the top-most Expansion Blade if the server unit is installed in a BladeCenter H or HT chassis.
Supported BladeCenter chassis
BladeCenter chassis support is based on the blade server type in which the expansion card is installed. Consult IBM ServerProven to see which chassis each blade server type is supported at the following address:
