what applications are running on the OS, and where the applications are
installed. Where is data being kept? In the VM, on a NAS/SAN,etc.? I
have VMware servers on Win 2000 Server Standard with 10 gigs. Those
VM's are never intended to be upgraded to Windows 2003 or higher, so 10
gigs leaves me with about 4.5-5 gigs free. All they do is run IIS 5.0.
10 gigs doesn't get you very far with Windows 2003 Standard on just a
base install alone, and if you want to in-place upgrade to 2008, forget
about it. I install heavy apps on a separate VMDK, so the boot disk
doesn't need to be overly large. Things like logging can be redirected
to additional disks. That means a boot partition disk can stay small,
but a "data/app" partition disk can be big.
IMO, One of the beautiful things about VM's is the disks can be expanded
if they are simple partitions. If it's a non-boot disk, it's really
easy. Shut down the VM, expand it with vmkfstools (you can even do it
in VI Client under ESX 3.5.x) and then boot the VM and run expand on it.
On a boot disk, you need to attach the disk to a secondary VM to expand
it, because you can't expand a boot volume once booted from it. I've
done this dozens of times without issue. There's always the risk of
losing the disk/partition however.
FWIW, My standard VM boot partition for Windows 2003 Standard Is
30-40gigs. Doesn't matter what I'm actually running. That yields me
plenty of free space to keep hotfix/server pack uninstalls as well as
future room for upgrades to Windows 2008. All my Server VM's have at
least one secondary partition as a second virtual disk file. All my XP
client VM's are usually 15gigs, but nothing really runs on them except
the OS and office apps. All data is elsewhere on the network.
PS - 2 of my most active VM's run separate Windows 2003 SBS environments
on ESX 3.5. Two 40gig boot disks, and two 120 gig data disks. No
performance issues related to I/O.

Please then Joe, (you are thinking exactly as I was).
What is your take on a small, medium, or large virtual disk?
(consider theat they must be large enough to be considered usable)
I will even entertain two classes: Servers, and VDI targets (I am
sure you all understand what I mean)
