We are about to setup a new Hyper-V server with 8 SCSI drives.
It will run 2 Virtual Servers
1- SBS 2003 Domain Conrtoller with exchange and BESE
2- Server 2003  App and data server

Were looking for best performance with not losing to much HDD space

I will vote for 2 RAID1 for OS, the use the 6 DISKS in RAID10 configuration and use fixed disks

HYPER V needs the fastest disk IO you can afford.

15k 300gb raid 10 - partition for host OS and VM's

create VM OS VHD's (IDE emulated) and Data VHD's in VM partition

dynamic vs fixed vhd's - OS/database/exchange need fixed, files can be dynamic.

if you really want to save on drive space consider differencing disks for OS vhd's.

consider installing server 2008,  smb2 has much higher performance for file transfers and will better serve your network as your network is refreshed with new hardware.

at least two quad cores and 24-32 GB ram will allow you to run more VM's

server 2008 allows 4 vm's per license

good luck!

@Busbar - could you elaborate?  i've gone the raid 1 route and see unused drive space that is slow compared to all raid 10.  I see hyper v as kind of a game changer for separate host os drive. specailly with differencing disks and ms working on vhd 'right-sizing' technology (grow and shrink as needed)
