• File and block protocol statistics

In addition to Ethernet and Fibre Channel throughput statistics, server performance can also be measured in operations per second (ops/sec). The NAS Manager provides a graphic representation of ops/sec, at two levels:

• Total operations per server.
• Total operations per individual file system.

The total operations on a server is an aggregate of the operations performed by all file systems hosted by that server.

Understanding the performance profile of servers and individual file systems is especially useful in environments where more than one server is installed, as it enables intelligent relocation of EVSs or file systems to more equally distribute the load among the available servers.
