Hi,

I have installed Windorws 2012 R2 on my Poweredge R900 it has raid controller Perc 6/I with 5 SAS 300 GB HDD but i am not sure on what level of raid the OS installed. When I check the the disk manager C: drive shows 790 GB but as a Dell Virtual Disk shows 1.35 TB approx. Could any one please explain what level of raid the OS is on and how to check it.

Thanks
