The IBM BladeCenter PCI Express Gen 2 Expansion Blade II provides 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. It provides 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.
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.
Ability to stack up to four expansion blades on a single base blade
You can attach up to two, three or four expansion blades, 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.
CFFh slot still available
The CFFh expansion connector is accessible on the top-most expansion blade, 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.
