    Posted Nov 21, 2011 05:36 AM

    Hi,

    please why there is so big disk preconfigured with vCenter Virtual Appliance? Is it necessery to configure it as Thick? Is it ok to change 8GB memory to 4GB? Becouse I have tried to change memory to 4 GB once and performance was awfull. After I changed back to 8GB, it was ok again.

    Thanks.

    As per Vmware it depends on the number of host in the environment.

    Option

    Description

    4 GB or higher

    Memory requirement for fewer than 10 hosts and 100 virtual machines in the VMware vCenter Server Appliance inventory.

    8 GB or higher

    Memory requirement for between 10 and 100 hosts or between 100 and 1000 virtual machines in the VMware vCenter Server Appliance inventory.

    13 GB or higher

    Memory requirement for between 100 and 400 hosts or between 1000 and 4000 virtual machines in the VMware vCenter Server Appliance inventory.

    17 GB or higher

    Memory requirement for over 400 hosts or 4000 virtual machines in the VMware vCenter Server Appliance inventory.

    Also 8GB is affordable i belive. try with 6GB ram if the performance is not good with 4 GB and go for 8 Gb even its bad with 6 GB.

    refer the below link:

    You can use thin disk without issues.

    About the vRAM, the minimum required for the vCSA is 8 GB (see the VMware documents).

    If can work with less, but it not supported.
