Data hosts connect to the storage resource card (SRC) sets, through the Fibre Channel (FC) ports on the service panel. The SRC set consists of two cards: the SRC processor card and the storage I/O (SIO) card. SRC sets are always configured as pairs, so each system has at least two SRC processor cards and two SIO cards.
Each SRC set has the following characteristics:
Note -
To make optimal use of the processors on the storage resource card sets, use the ports for storage connections in the following order: 8,6,7,5,4,3,2,1.
The number of SRC sets determines the number of initiators that can be connected to the system. Each system can be configured with a minimum of two SRC sets, for 16 FC ports, and a maximum of four SRC sets, for 32 FC ports.
