So my question is now, how best to partition my new server. I use it for the following:
1.) Hyper-V VM host (~300GB)
- Exchange 2010
- Linux Anti spam/virus/phishing filter in front of exchange
- Apache web server
- subsonic media streamer
- various other vms
2.) TV show / Movie repository for streaming to XBMC (~7TB)
3.) SVN Server for code/Electronic schematics/board files/gerbers (~80MB)
and a few other things. The RAID 6 array has a 64KB stripe size, and while it currently has 6x3TB drives, I bought a new case and 4 5-in-3 drive cages to allow me to increase it to 20 3TB (or 4TB in the future) drives.
1.) Create one large array, then partition it into separate drives
2.) Create smaller RAID 6 arrays (or possibly RAID-1 arrays for critical stuff)
3.) Create multiple, different type arrays for each specific function above
My requirements would be that if necessary, I should be able to expand a volume if it needs more space (in windows drive manager), and that when space runs out, be able to easily add in and expand the array(s) with new drives. I am familiar with OCE, but im not sure if I can span different arrays on same drives (say a 4TB RAID 6 array, spanning 5x 3TB drives, plus a 4TB RAID-1 array on those same 5 drives). Ideally I'd prefer separate partitions/arrays, so that I can specify different block/strip sizes (SVN stuff is usually small, so say 32 or 64KB for that, whereas TV and movies are usually several gigabytes, so maybe a 512 or 1024KB strip for those).
Anyone have any recommendations?
