Low disk space and virtual memory settings

    I have a problem with disk space on C: and constantly get messages that
    space is low. Currently there is around 500mb on a 12Gb partition.

    I have put most stuff on D: which is a 72Gb partition with lots of free space.

    When will I see a performance hit and can I alter my virtual memory
    settings to ease the load on C:?

    I currently have 1536Mb allocated to c: with a maximum of 3072Mb. I
    have 1Gb of physical RAM in the server.

    Would it be wise to reduce this and allocate more to D:?

    Hi Martin... 12GB partition.... this is a Dell server....lol

    Unfortunately my experiance is that 12GB is too small and our Dell servers
    we flatten and reinstall.

    Appreciate this doesn't help you...lol

    I would download treesize http://www.jam-software.com/freeware/index.shtml ,
    great utility to view where space is being used up.

    I would put paging file onto other partition ( dumpchk not available then
    but then who knows how to read them...lol) However before doing so:-

    1. 1GB RAM is too low for SBS would recommend 2GB for standard and 4GB for
    premium but then usuage, no of users is a factor.
    2. I assume you are backing up exchange? This will clear the logs.
    3. Most stuff on D, does this include Exchange database and user folders ?

    What I have learnt along the way is the 'monitoring and reporting ' logs,
    these can build up and at install we now redirect exchange database and
    monitoring and reporting off C drive. On this point if someone knows how to
    redirect the sql directory for monitoring and reporting would appreciate it.

    Let us know how you get on.

    Yep :)

    I'd entirely agree
    Back up is using Veritas. What method are you referring to to clear the logs?
    Everything except Exchange at the moment. I have moved all other
    standard stuff as per knowledge base articles

  4. Martin:

    Another viewpoint: Although I now use larger sizes on SBS System
    partitions, I have a couple of SBS2003 servers installed early in the
    SBS2003 lifecycle which have 12GB System partitions. About 50% of this
    space is actually used with the other 50% being free. This remains more
    or less stable over a period of many months.

    How? ALL of the selections on the "Data" page of the Integrated
    Installer were moved to other volumes. So ClientApps, Users, Exchange
    info store and logs, SQL Server databases (monitoring, WSUS), etc. are
    NOT on the System partition. And I also moved the page file, as Maxibo

    The main things that seem to use up System partition space on those
    servers are the compressed uninstall folders for the updates to SBS (and
    its components) and antivirus signature updates. Both of those can be

    I agree with Maxibo that you need to find out what's using up the space.
    In addition to the utility he suggests, the Microsoft DIRUSE utility
    performs basically the same function. It is in the \Program Files
    \System Tools folder if you installed the system tools from CD#2.
