DSS on ESXi 4.1 - Slow RAID5 Reads?

[npusnik]

Update:

Re-initialized the arrays, gave DSS raw access to the 1.8TB array - both virtual and physical RDM methods.

Results:
Write, 60-70MB/sec
Read 20MB/sec

I only have the option for Write Through or Write Back - and I'm not sure why those would effect reading from the LUN - but I'll change it next and see what the results are.

Another update:
Created an ISCSI volume using FILE I/O, mapped the target to my Win 7 management desktop

Results
100MB/Sec write
20MB/Sec read

I'm going to try to install Dell's OpenManager to see if there's something I'm not catching with the PERC's RAID5 array.
