I think the only way is to pick 2 drives and make them a raid 1, and then create a seperate virtual disk on the other 4 drives. Easiest would be to install the OS (on the 2-disk raid 1) and use OpenManage to create the other virtual disk.
Note: you can never boot to a virtual disk that is over 2TB in size.

Exactly what i meant. What i wanted is from those 6 drives, to create 2 virtual disks, let's say vd0 that has small space only; only for boot up, and the 2nd, vd1 that has the bigger capacity. Is this definitely not possible?
If i have to create 2 RAID configs, not only i sacrifice the space (although later on maybe i can combine with LVM), and also i must live with lower RAID levels.
Raid 5 is not the greatest choice with SATA drives.
When a raid 5 set runs into a bad sector on a hard drive during a rebuild the raid fails to rebuild and the only way to 'fix' it is to back up data, destroy the raid 5 and recreate it.
As SATA drives are generally larger, there's more data to rebuild, which obviously therefor takes longer, and as SATA drives are slower (than SAS/SCSI) drives, making the duration of the rebuild (time window that your raid is in a degraded state) all that much longer.
If your budget doesn't allow (for raid 6 or raid 10), make sure you have a good backup solution in place and run checks on the raid set every few months or so.
