Half-length cards are supported, however. Video adapters are not supported. The PCI Express slots support x4 or x8 PCI Express adapters only. It is recommended that for performance reasons, you do not install more than two high speed (that is, 8 Gbps or faster) PCI Express cards per PCI bridge (bridge 1 is slots 1, 2, 3 and 4; bridge 2 is slots 5, 6, and 7) with a maximum of four per system. Examples of adapter cards that have bandwidth maximums of 8 Gbps or more include 10 Gbps Ethernet card and dual-port 4 Gbps Fibre Channel cards.
