Configuration Limits
The following table describes the supported configuration limits for a PS Series group running version 9.1 of the PS Series firmware:
NOTE: For the purposes of this table, a PS4XXX array is defined as any array in the PS4000-series family, which includes
PS4000, PS4100, PS-M4110, PS4110, and PS4210 systems. Only two PS4XXX-series arrays can be in a mixed group of multiple
array types. A group consisting entirely of PS4XXX-series arrays has only two members. When a group contains a mix of
PS4XXX arrays and other array models, the higher limits prevail.
