Basic RAID question

A few ways:

In the OS: You should have the management software (OpenManage Server Administrator) installed on any server you manage - in here you can simply go to Storage, PERC, Virtual Disks to see the RAID configuration(s).

In the RAID configuration utility (CTRL-R during POST).

Do the math: Can you tell how many physical disks are in the server? Any idea how big they are? How many "disks" does the OS see and how big? You can usually figure it out.

looks like there are 10x 2TB and 2x 1TB drives

the OS shows just over 10TB on the raid.

Im going to try the openmanage software and see if that confirms the RAID
