Hello, There are so many benchmarks out there. Much depends on filesystem vs. RAW, random vs. sequential, large vs. small blocksize.
If you keep the capacity tested small then you will get a better idea of network performance vs. actual storage performance. I often use IOMETER with Windows. AFAIK, IOMETER with Linux is still basically broken based on the libraries they are using you don't get proper threading to increase IO loads. Acts basically like a single threaded copy. I like that I can create various tests using different loads and run them one right after the other in a single configuration file. With IOmeter you can set a very small test size to basically insure you are getting cache reads to verify what your hosts, NICs and switches can do. Then test larger values if you want to actually test backend storage.
