I have a server that is connected to a SAN (Dell Compellent) and due to space concerns I am looking into installing some physical disks into this server to 'offload' some data being used by the server on the SAN. The server has several volumes using the SAN, one of which is the OS/system drive. I want to leave this on the SAN, but replace all other volumes with the physical disks.
I plan to clear the disks beforehand using another server, and also to install them offline (i.e. not hotplug them) for safety.
My question is - Will simply plugging the disks in be ok (And will I then be able to format and configure them in disk manager in windows) or do I need to configure them using the RAID configuration software that loads before the OS (I have very little experience with server RAID setup)
The server in question is a dell poweredge 1850 (not sure which generation at the moment) running windows server 2008 Standard.
