You create a new virtual disk in a storage pool by using the New Virtual Disk Wizard.
You discover that the new virtual disk has a write-back cache of 1 GB.
You need to ensure that the virtual disk has a write-back cache of 5 GB.
What should you do?
A.
Detach the virtual disk, and then run the Resize-VirtualDisk cmdlet
B.
Detach the virtual disk, and then run the Set-VirtualDisk cmdlet
C.
Delete the virtual disk, and then run the New-StorageSubSystemVirtualDisk cmdlet
D.
Delete the virtual disk, and then run the New-VirtualDisk cmdlet
It isn’t possible to set a write-back cache custom size by using Server Manager Windows Server 2012 R2. By default, if you create a virtual disk using Server Manager, it will create a 1GB write-back cache if sufficient space exists on solid-state disk (SSD) storage in the pool.
If you want to customize the write-back cache size, use the Windows PowerShell cmdlets and the -WriteCacheSize parameter, for example:
New-VirtualDisk -StoragePoolFriendlyName “My Storage Pool” -FriendlyName TieredSpace -StorageTiers @($ssd_tier, $hdd_tier) -StorageTierSizes @(50GB, 300GB) -ResiliencySettingName Mirror -WriteCacheSize 2GB
Note: After a virtual disk is created, its WriteCacheSize can’t be modified.
