Note: These specifications are for a dual-controller, high availability (HA) system. Divide numbers by 2 for a single-controller system configuration.

[1] Flash Cache modules of different sizes can be mixed in the same controller so long as both sizes are supported with that controller. Maximums must not be exceeded for number of modules and quantity of added read cache. For example, the maximum number of modules for a FAS/V6240 high-availability system is 12, and the maximum quantity of added read cache is 6TB. Note that the original PAM module and Flash Cache modules can never be mixed in the same controller.

[2] The FAS/V6210/20 systems can be configured with one 1TB module plus one 512GB module per controller. This configuration equals the maximum of 1.5TB per controller and 3TB per high-availability system.

[3] One 512GB module is integrated as a standard feature with each controller in FAS6240, FAS6280, V6240, and V6280 systems.

[4] Flash Cache is not supported with Data ONTAP 8.1 running on the FAS/V3210 and FAS/V3140 systems
