Re: RAID Config for a DL380 G6
Microsoft recommends RAID 1 or 10 for OS and paging.
You could do one RAID 10 array, 6 active, two spares for fail over. Two logical paritions
I would keep RAID 1 separate from RAID 10 unless you have a SAN. RAID 5 could be very slow on parity writes.

Re: RAID Config for a DL380 G6
Microsoft recommends RAID 1 or 10 for OS and paging file. I usually do OS, paging, and app/data partitions. I keep paging separate because in Windows 2008, you can extend and shrink a partition without a paging/swap file. In 64-bit OS, I usually do 60 GB paging/swap partition.

Re: RAID Config for a DL380 G6
I agree. if you create just 1 logical drive with RAID 1+0, you would get only half of the space (1200 GB).
So if you want to save another 600 GB space
create Raid 1 with 2 hard drives and Raid 5 with 6 hard drives.
this way your OS will get extra protection and performance by implementing recommended raid 1, and more space by implementing another raid (raid 5) for data.
Raid 5 read performance is excellent and write performance can also be manage with BBWC and stripe size, acelerator settings.
if the data for which you are creating seperate raid 5 is not database type (where you need simaltanious read or write depending on the application) then Raid 5 is the ideal choice for your environment.
example of my setup..
I have Raid 5 with 5 disks setup for an application which not write extensive and writes are equal to my stripe size, I get wonderful performance.
thanks,
Aftab
