  • 1.  how to pre-allocat space in hard disk

    Posted Nov 09, 2017 08:08 AM

    Hi, I'm studying for Foundation exam and I'm trying to configure my VM hard disk and the requirements are as following:

    1- System Disk (4GB) with no pre allocation space (this is thing provisioning right?)

    2- data Disk (20GB) with zeroed in advanced

    what does zeroed in advanced mean? also , is there a different in hard disk type between system disk and data disk?

    thanks

    Yes - this is called Thin-provisioned.
    > 2- data Disk (20GB) with zeroed in advanced

    Here you want Eager-zeroed Thick-provisioned.
    With Eager-zeroed Thick-provisioned the space is allocated completely in advance and is filled with zeroes before first usage.
