FAS2220, FAS2240 single-controller limits

Each system model has configuration limits for reliable operation. Do not exceed the tested limits.

The following table lists the maximum supported value for each parameter based on testing. All values are for FC and iSCSI unless otherwise noted.

Note: The FAS2220 configuration does not support FC but does support iSCSI. The values listed are the maximum that can be supported. For best performance, do not configure your system with the maximum values.

The maximum number of LUNs and the number of HBAs that can connect to an FC port are limited by the available queue depth on the FC target ports.
