Measuring IOPs on LUNs using fast cache
When looking at IOPs for a LUN on a CX-480 using Analyzer, are the IOPs that hit data located in fast cache reflected in the value? If not, is there a way to get the total IOPs including data from that LUN in fast cache? Thanks.

If you are checking the total throughput (for example) statistic in the Analyzer for a particular LUN, it will show the IOPs value coming from the FAST Cache also. If you turn ON FAST Cache for that LUN and observe the Total Throughput value, you would see that value increasing over a period of time - indicating the performance boost you are getting from FAST Cache.

Avi,
Does total throughput also include SP Cache hits as well as FAST Cache hits?
Thank you,
Rebecca
