232 Configuring Directors
CP blades
The 4/256 Director supports the CP4 blade. The DC Director supports the CP8 blade.
Mixed CP blades are not supported on a single chassis, except during specific upgrade procedures
detailed in the HP StorageWorks SAN Director hardware reference manual. CP4 and CP8 blades cannot
be mixed in the same chassis under any circumstances. HP recommends that each Director have only one
type of CP blade installed and that each CP (primary and secondary partition) maintains the same
firmware version.
Core blades
The DC Director supports two CR8 core blades. This blade is used for intra-chassis switching as well as ICL
connectivity to another DC Director chassis.
The 4/256 Director does not support core blades.
Port blade compatibility
Table 65 identifies which port blades are supported for each Director.
