SED Disk Encryption

Afternoon All,

Was wondering if somebody could help me please, i have just purchased a PowerEdge T140 server with a single SED drive, i am trying to work out how to get the drive encrypted, i have created a RAID with the single drive and done a virtual disk and installed the OS, when i install Support Assist Enterprise it is telling me the disk isnt encrypted?

I have tried to search online for some for of guide but cant seem to find anything, could somebody point me in the right direction please, do i need to actually enable encryption if so where is this done, is this done prior to the OS install?

Any help would be very much appreciated as im kind of at a lose at the moment.

Many Thanks

P
