  • 1.  Huge size of a disk storage

    Posted May 13, 2010 04:17 AM

    Hi,

    We have a file server with Windows 2008 R2 and we are looking to offer to client a 2TB disk space for the files.

    What would be the best way to provisioned a 2 TB hard disk drive for a server ? VMFS or RDM

    We are using vSphere 4

    Thanks in advance

    Sebastien

    As per the VMware standard recommendation if you are assigning the LUNS for the VMFS file system..then it should be 512GB - 512KB.

    In the current scenario if you are looking it out for 2TB disk for the VM, then you should go for the RDM. Since it would be dedicated for the VM and due to the less I/O request the performace would be better and it would be easy to manage.

    you have the option of using a 2048mb VMDK if you set it to an 8mb block size. have a read on block sizes

    Yeah thanks, I already know about those block size. Actually I know very well my VMware. It's just I was wondering about a best practice and to have some suggestion and confirmed some point.

    Thanks for your add.
