Storage Spaces in windows 10

Hardware Hub Storage

Im trying to setup .

im using 1 LSI drive for cache and 4 HDDs that should run in parity.

I found this script on gitup which sets everything up the way i want. however it sets up the hdd pool as mirror. I am a prowershell dummy and cant figure out how to change the script so it creates the HDD pool using parity. any help would be appreciated.

If I’ve read the script correctly, you should be able to change
$DriveTierResiliency = "Simple"
to be
$DriveTierResiliency ="Parity"

EDIT:
If you want to learn more about what this is doing, the MS PowerShell docs are actually pretty awesome. Here’s the page for the New-VirtualDisk cmdlet, which is what’s doing the majority of the work here: New-VirtualDisk (Storage) | Microsoft Docs

its not that simple. i tried that and it fails. i can get it to this point

FriendlyName TierClass MediaType ResiliencySettingName FaultDomainRedundancy Size FootprintOnPool StorageEfficiency

SSDTier Unknown SSD Simple 0 0 B 0 B
HDDTier Unknown HDD Parity 1 0 B 0 B

but then trying to create a new virtual disk fails with this not so help full msg

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.

im at a loss. does windows 10 pro not provide the features i need?

So i managed to get it to work.

FriendlyName TierClass MediaType ResiliencySettingName FaultDomainRedundancy Size FootprintOnPool StorageEfficiency

SSDTier Unknown SSD Simple 0 0 B 0 B
HDDTier Unknown HDD Parity 1 0 B 0 B
My Tiered VirtualDisk-SSDTier Performance SSD Simple 0 362 GB 362 GB 100.00%
My Tiered VirtualDisk-HDDTier Capacity HDD Simple 0 9.59 TB 9.59 TB 100.00%

what i am not sure about is since the virtual disk is simple but the hdd pool has parity, if a drive fails do i still have redundancy? i assume yes but i just want to be sure.
