WSUS installation drive

    I will be installing WSUS on our SUS server. It has two partitions, the C:
    and D: drives. The C: partition only has 3 gigs available and houses the
    system files. The D: partition includes programs and has 25 gigs free. I
    want to install WSUS on the D: drive due to it being the larger drive. Are
    there any issues to installing WSUS on a drive other than the C: drive?

  2. It will be a tight fit. During setup you can specify that you want the
    updates themselves stored on a different drive, but the core WSUS files are
    always installed to %program files%\Update Services, which is usually also
    located on the system drive. WSUS requires (and checks for) 2gb free on the
    system partition during setup.

    So WSUS setup doesn't let you choose what drive to install the program files
    to, only the updates? In that case I can then choose to have the updates
    either store on the D: drive or to be left on the windows update site.

  4. Correction... WSUS requires, and checks for /1GB/ free on the system
    partition... but \Program Files\Update Services only requires 268MB of
    actual space after installation.

    The \WSUS tree can be installed anywhere, but WSUS requires, and checks for
    some unknown amount (during the beta it was 7GB!) on the drive where \WSUS
    will be held. See my message in the thread "Minimum Disk Space Requirements
    still enforced???" for a workaround if WSUS chokes on not enough space on
    the non-system partition.

    As for content storage.. my WSUS RC, with all patches for Windows XP,
    Windows Server 2003, Exchange, SQL, and Office that were available as of
    last week took only 3.6GB of space for an English-only installation. Five
    hundred MB of that was the SUSDB.MDB file.

  5. Mike.. you won't have any problems at all doing the install with the
    resources you have available. WSUS will install the core files (which
    basically contain the web service asmx files) on the system partition, but
    give you the option to install the database and content store elsewhere.

    Note: It's a trivial exercise in IIS Administration to move the majority of
    the \Program Files\Update Services folder tree to a non-system partition
    after installation. The majority of the changes would simply involve
    redirecting the virtual directories in IIS Admin, and I suspect a few
    references in the registry.

  6. I'm assuming that is without the Express Installation Files? My /WSUS tree
    is now 7.47 GB - yes, English Only. Furthermore, I download Critical
    Updates, Security Updates, Service Packs, Update Rollups, and Updates for
    Office, SQL and Windows.

    Do you know of any residual stuff that can be deleted from the RC or WUS?
    I've used the same server for all.

  7. No.. actually that was /with/ Express Installation files, and included
    service packs as well. It also included pre-XPSP1 updates, which I don't
    think anybody needs to maintain -- I downloaded them only for testing

    What I don't have is Windows 2000 stuff, though. That could account for a
    lot of the difference if you have Windows 2000. Also, I don't have
    Datacenter-only content, nor did I download any 64-bit content.

    On my production deployment, though, I'm only going to maintain approved
    content for post-XPSP2 and post-Win2k3SP1 content, along with
    Office/Exchange/SQL -- I'll let you know how that goes as soon as I get the
    content downloaded.
