I'm setting up the hardware for a small home office. The plan is to run
Hyper-V server with several small server clients. To ensure maximum speed
I'm considering installing it on a SSD. Specifically a Crucial SATA 6G SSD
(256MB) controlled via an ASUS U3S6 controller.



Will Hyper-V Server install onto a SSD?
Does Hyper-V Server support TRIM commands?
Will it work with Windows 7 (64bit) drivers?

TIA

Honestly, this doesn't make a lot of sense, given the costs. Spend your
money on the VHD storage subsystem, with good SAS disks in a wide array, and
a really good hardware RAID controller. The parent OS can comfortably
install on a 60 or 80 GB drive, and isn't the limiting factor for
performance.

Generally, Win7 drivers will work for R2. I don't know if TRIM is supported
in R2, but I suspect not.

Hyper-V itself will install, but doing so would be pointless since
Hyper-V itself is so lightweight.

You might want to store your virtual hard drives on an SSD though.

In this context, TRIM won't really matter. I'd guess that R2 will
support TRIM natively similar to W7, but I'm not aware of any mechanism
that would support TRIM within a guest and pass TRIM out to the host, so
the useful of TRIM will be drastically reduced. In other words, plan
for no TRIM support and look for a controller (like Crucial's latest
firmware) that supports garbage collection as an alternative to TRIM.

Another issue is cluster alignment, aligning a physical partition
correctly should happen automatically but guests may well not end up
aligned to the physical cluster boundaries of the SSD, incurring
significant write penalties.

Yes, the plan is to install the VHDs along with the Hyper-V server on the
SSD. This setup is being built with power usage as a major consideration as
it will be on 24*7*365. Bulk data storage will be on a NAS.

Due to the lower power CPU I'm looking at an SSD to help maintain
responsiveness.

After my initial post I discovered that Crucial's firmware does make TRIM
less important.

Thanks for the heads up on cluster alignment. I hadn't read deep enough
into the literature to be aware of this.
