RAID Volume Configuration Advice

Hello Forum!

I just discovered Proxmox and I'm in the process of building a server to migrate (new installation) my Windows 2003 Terminal Server (about 35 users) to 64-bit, and to test the possibility of consolidating additional servers to this new box. The server that I am building is a 2 x Quad Core Xeon 2.4GHZ with 24GB Ram with 8 hot-swap enclosures and a 5805 Adaptec Raid controller with Battery Backup.

My question involves the most optimum way to set up the drives for flexibility, performance, and expansion. I'd assume that the OS should go on a completely separate raid volume than the actual VM's? Should I just setup a mirrored volume for the OS and create one large raid 5 volume using 1TB drives for the VM's? Ultimately, I'd be interested in testing the HA ability of Proxmox using LVM and DRBD if the installation and testing is a success.

Your insight or advice is greatly appreciated.

Well, it is quite hard to find an optimum for everything, and I am sure the optimum is different for different people ;-)

IMHO, you do not really need a separate RAID for the OS. And I would prefer RAID 10 (instead of slow RAID5).
 
Hi,
if you want speed use raid-10! And if you mostly use kvm (windows...) i would prefer a small raid-volume for the installation (200-500G) and perhaps two or three bigger raidvolumes (for lvm-storage, or drbd with on top lvm-storage). So you can choose on which storage a guest schould run - or append an raidvolume to the pve-volumegroup to use the space for openvz.

Thanks for the responses. I don't think RAID 10 will be a problem on this controller. One more question: can I set the server up for LVM on DRBD in anticipation of building another box for HA, or must I have both boxes ready to go for this setup?
