Does Windows Server 2016 (or Windows Server 2012 R2) allow the creation of a Tiered Mirrored Storage Spaces volume with the following configuration:
HDD tier: 2 HDD same size, mirrored (RAID 1)
SSD tier: 1 SSD drive
For example, I have 2 x 136 GB HDD and 1 x 250 GB SSD that I want to set up as a single volume of 386 GB (136 GB + 250 GB) in such a way that the HDD is protected through RAID 1 but the SSD is not mirrored. I can then use the SSD for Write-back cache and to store hot data through the Tiered feature of Windows Storage Spaces technology.
So the questions are:
- Whether I can have just 1 SSD even though there are 2 HDD?
- If this is not allowed in Windows Server 2012 R2, please indicate whether it is allowed in Windows Server 2016.
- If this is not allowed via the New Virtual Disk wizard, but allowed through PowerShell script, can you provide the commands to create the pool + virtual disk?
