I was searching for a long time for a simple tool which can tell us the controller throughput of any SAN environment. Its necessary for every Storage engineer to have this utility to cross verify the subsystem we buy. Ofcourse the vendor will have the tool or LAB benchmark for the same. But those will work on the connected environments - I mean the san subsystem connected with multiple nodes with File system etc. Instead of that we should have a tool which helps us to find out the exact back end performance of the controller. Even its single or dual on SAN path. Does anyone have any idea on the same. Incase of more clarification let me know. We can discuss further and we can create something new for the storage industry. What say?
