In addition to the number of disk drives, the system can be configured with disk drives of different
capacities and speeds, varying numbers of CHAs and DKAs, and varying cache capacities, as
follows:
• Two to six CHAs (each is a pair of boards). This provides a total of 12 when all of the CHA
slots are used and there are no DKAs installed, as in a diskless system. The maximum total
number of CHAs and DKAs is 12.
• Two to four DKAs (each is a pair of boards). This provides a total of 8 when all of the DKA
slots are used. When all 4 DKA pairs are installed , then up to 8 CHA pairs can be installed
• Cache memory capacity: 32 GB to 2048 GB
