Vista - Hyper-V: Harddisk I/O on host

Hi

How intensely is are harddisk operations at the hostsystem (core
installation) on a hyper-v system?

. . .I don't know, if I want to place one vhd on the same physical harddisk
as the host-system. I want to be sure, that the two systems (core and vhd) do
not slowdown each other due to harddisk activities.

Thanks for your input.

The more OSes you have on one spindle the more it will affect
performance. Ideally, you'd want the host OS and the VM on their own
disk.
Disk contention is one of the bigger performance factors when you run
on a single disk.

However, since you're using a core installatio, the disk usage by the
host should be minimal since all it should be doing is hosting the
Hyper-v role.

Steve is correct. Approach your Hyper-V system designs much as you would in
the physical world. If you would separate your SQL server DB files and Logs
onto separate spindles for performance or if you would separate your
NTDS.dit file from the logs and from the OS volume, then follow this same
methodology when creating the architecture for your Hyper-V systems. Keep
the OS (Core or not) on a separate volume (mirrored maybe?) and use as many
additional disk spindles as possible for your Hyper-V VMs. Whether this is
on a SAN or local storage or whatever, more disks = less disk contention.

Hope this helps,
