Up to 20 PCI Express (PCIe) ExpressModules (EMs) are supported in the Sun Blade 8000 Modular System. Each EM supports an industry-standard hot-plug capability. All EMs connect to a chassis midplane that provides an interconnect between the chassis blades and the EMs installed in the chassis. The midplane connections between the chassis blade and the EM are logically defined by the midplane as shown in the following table. Viewed from the back of the chassis, the following table lists the blade-to-EM assignments.

As shown in the previous table, a pair of EMs are assigned to each blade in the Sun Blade 8000 Modular Chassis.
EMs provide flexible I/O configuration options including, but not limited to, the following:
Storage
Networking
Clustering
Initially, for example, the Fibre Channel (FC) EM will provide a dual 1/2/4-Gbps connection to chassis blades.
The following figure and associated table provide more information on the FC EM.
