Determining efficiency of a virtual array in a virtualized storage system

A storage system comprising:

• at least one host for requesting storage operations;
• at least one virtual array, coupled to the host, for receiving storage operations requests;
• a backend array, coupled to the virtual array, comprising physical storage, for storing data for the virtual array;
• at least one management server for:
• determining an input throughput data rate between the one host and the virtual array based on storage operations between the host and the virtual array;
• determining an output throughput data rate, from the virtual array to the backend array, wherein the output throughput data rate is based on the storage operations that require access to the backend array;
• and
• determining an efficiency between the input throughput data rate and the output throughput data rate so as to measure the efficiency of the virtual array.

A method for determining an efficiency of a virtual array, the method comprising:

• determining, using a computer, an input throughput data rate between at least one host and a virtual array based on storage operations between the host and the virtual array;
• determining, using a computer, an output throughput data rate, from the virtual array to a backend array, comprising physical storage, of the storage operations, wherein the output throughput data rate is based on the storage operations that require access to the backend array;
• and
• determining, using a computer, an efficiency between the input throughput data rate and the output throughput data rate so as to measure the efficiency of the virtual array.
