Installing SAN Health

Select a suitable workstationAny Windows box that has TCP/IP connectivityto the management port of the SAN switches.

CPU and memory requirements are dictated by the numberof switches that you wish to concurrently audit.

Less than 20 switches at once requires 128MB RAM anda 500MHz CPU.

The memory requirement then grows exponentially to 68 switches atonce (max supported) which requires 2 GB of RAM on a 3GHz CPU.
