Hello,
We have current situation
Intel S5520UR with latest raid, bios , uefi updates. Raid is integrated LSI SAS1078
There are 6 Sata x 2 TB HDD with RAID 1(2 TB, WinOS) and raid10(4 TB, Data).
At the moment there are windows server 2012 GUI with hyper-v installed ant there are 5 virtual servers installed
on 4 TB (raid10) drive, and the problem is that HDD performance is crappy.
Highest active time is often 100%, and response time for VHD files is around 30-50.
As i see, there are no drivers for S5520UR for windows server 2012, so it uses integrated win drivers.
One idea is to enable HW raid adding
1) Activation Key: AXXRAKSAS2
2) Memory: AXXMINIDIMM512.
or reinstall using windows 2008, which has all the drivers.
Will i gain any noticeable performance if i enable HW raid over SW raid ?
