    Hyper-V Server - install on a SSD

    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.
