@ajnozari would Kindly post the powershell you used? I can't get @Catsrules's solution to work at all. For me the command (using @Catsrules script naming) should be:
$vdisk1 = New-VirtualDisk -StoragePoolFriendlyName TieredPool1 -FriendlyName Tiered_Space -StorageTiers @($tier_ssd, $tier_hdd) -StorageTierSizes @(100GB, 250GB) -WriteCacheSize 25GB ( I added the write cache, want lots of that I think)
However I get:
PS C:\WINDOWS\system32> $vdisk1 = New-VirtualDisk -StoragePoolFriendlyName TieredPool1 -FriendlyName Tiered_Space -StorageTiers @($tier_ssd, $tier_hdd) -StorageTierSizes @(100GB, 250GB) -WriteCacheSize 25GB
New-VirtualDisk : Not Supported
Extended information:
The storage pool does not have sufficient eligible resources for the creation of the specified virtual disk.
Recommended Actions:
- Choose a combination of FaultDomainAwareness and NumberOfDataCopies (or PhysicalDiskRedundancy) supported by the storage pool.
- Choose a value for NumberOfColumns that is less than or equal to the number of physical disks in the storage fault domain selected for the virtual disk.

At the moment I'm playing around in a VM which might have something to do with it. However what I'm trying to achieve is I want to build a box with several independent 12TB (not striped) each with their own SSD WriteCache and hot block area. Kind of like a Mac Fusion Drive. I want to host plex and I want to serve 4K content and not have a write of say a 4K movie interrupt the 4K movie I'm watching.
What I would ultimately like to achieve is creating some VHDXs on a larger SSD and using them as the tiers on each disk pool (pool having only one VHDX SSD and a 12TB HDD), but given I can't make this work that seems unlikely so I was planning on buying small PCIe SSDs and a PCIE to SSD M.2 adaptor card.
