DSS 6.0up98.8101.7337 64bit with ESXi 5.0.0 degraded performance

Try to enable the Disk Cache, and if you have a CacheCade option in the card, try to disable it's options and see.
Also is your LSI running with the latest Firmware? if yes try to downgrade it to the previous Firmware for LSI.

Hi,

No CacheCade,

The firmware is 2.120.53-1235

Do I have to be concerned with possible data loss enabling the Disk Cache? or is that negligible in my setup? BBU + Duel power supplies + A+B Power feed, also including the secondary SAN?

If the BBU is charging it will be in a Write Through state thus being slower, wait till the BBU is fully charged then test again.
