Your network contains an Active Directory domain named contoso.com. The domain contains a server named
Server1. Server1 runs Windows Server 2012. You needto create 3-TB virtual hard disk (VHD) on Server1.
Which tool should you use?
A.
Diskpart
B.
Server Manager
C.
Computer Management
D.
New-VirtualDisk
E.
Share and Storage Management
F.
File Server Resource Manager (FSRM)
G.
New-StorageSubsytemVirtualDisk
H.
New-StoragePool
Explanation:
The New-VirtualDisk command creates a new virtual disk in the specified storage pool. New-VirtualDisk -Creates a new virtual disk in the specified storagepool.
Although the new Server Manager UI in Windows Server 2012 provides a very convenient and intuitiveworkflow
to provision and manage Storage, interaction with PowerShell is required to access many of theadvanced
features.
If I then create a simple 200GB Virtual Disk via the UI named VDiskSimpleUI, the resulting Virtual
Diskleverages 8 columns and maintains 1 copy of thedata. But when creating the Virtual Disk via PowerShell,
Ican force the tripping across all nine of the disks and optimize performance.
New-VirtualDisk -StoragePoolFriendlyName Pool01 -ResiliencySettingName Simple -Size 200GB -FriendlyNameVDiskSimplePS -ProvisioningType Fixed -NumberOfDataCopies 1 – NumberOfColumns 9
And creating a mirrored 200GB Virtual Disk via the UI named VDiskMirrorUI produces a Virtual Disk with
4columns and 2 data copies. But with PowerShell, I can create a slightly different configuration, increasing
thedata protection (and also the disk footprint):
New-VirtualDisk -StoragePoolFriendlyName Pool01 -ResiliencySettingName Mirror -Size 200GB -FriendlyNameVDiskMirrorPS -ProvisioningType Fixed -NumberOfDataCopies 3 – NumberOfColumns 3.
