Solaris Memory Utilization

Solaris servers uses certain percentage of free memory for IO cache.

This is based on the ZFS configuration.  This configuration can be checked using root or kernel access.

If there is no memory available, then these cache memory will be used.

If the Application need memory, the I/O cache will release the memory.

The "sr" value on vmstat provide the status of the Memory swap rate.

As long as the "sr" value stays at zero there is no memory issue.
