Looks like my reply never made it up here for whatever reason. I haven't had a chance to bench my Linux host in the remote office as it was running a monitoring package but wasn't needed anymore, so the local guy shut it down. I think I will simply build another for the purpose of testing.
The array in that location is a PS4000E that is only half-populated with 8x 1TB SATA drives. 2 are hot spares, leaving 6 as data disks in RAID-50 (no longer a best practice for SATA drives 1TB or higher). The numbers are surprisingly good for 6 data disks, especially SATA disks. The RealLife test results work out to 162 IOPS/spindle using the test workload.
Server is a Dell R610 (1x 5600-series, 16GB RAM, 6 Broadcom 5709's - 2 bound to iSCSI and configured by EqualLogic MEM script) running vSphere Essentials Plus 4.1. Virtual guest is Windows 2008 with 1 vCPU, 4GB RAM, and 60GB hard drive.

Will post the Ubuntu results as soon as I get a chance to install and configure.
