Feedback about Dell Compellent performance.

I do like to do annual review of our Dell Compellent/SAN. I did perform a quick (not comprehensive ) test few days ago and got the following results:

I do not have the complete specs of the hardware (yet) but I would like to know opinion about how it is running now. 

A quick glance tells me that the latency values look good to me. I have doubts about the throughput in MBs/sec.

This quick test was performed via SQLIO against one particular LUN that is holding data files for a SQL server. The SQL server runs on VMware by the way, using vmdk file format.

Any comments of feedback is welcome.
