With four servers, you can use dual parity, also commonly called erasure coding (compare to distributed RAID-6). This provides the same fault tolerance as three-way mirroring, but with better storage efficiency. To learn more, see Fault tolerance and storage efficiency. If you're coming from a smaller deployment, you have several good options to begin creating dual parity volumes. New-Volume -FriendlyName -FileSystem CSVFS_ReFS -StoragePoolFriendlyName S2D* -Size -PhysicalDiskRedundancy 2 -ResiliencySettingName Parity Specify PhysicalDiskRedundancy = 2 and ResiliencySettingName = Parity on each new volume upon creation. New-Volume -FriendlyName -FileSystem CSVFS_ReFS -StoragePoolFriendlyName S2D* -Size -ResiliencySettingName Parity Then, any new parity volumes will automatically use dual parity even if you don't specify it Get-StoragePool S2D* | Get-ResiliencySetting -Name Parity | Set-ResiliencySetting -PhysicalDiskRedundancyDefault 2 Set PhysicalDiskRedundancy = 2 on the pool's ResiliencySetting object named Parity. With four servers, you can also begin using mirror-accelerated parity, where an individual volume is part mirror and part parity.įor this, you will need to update your StorageTier templates to have both Performance and Capacity tiers, as they would be created if you had first run Enable-ClusterS2D at four servers. #ADDING SYNIRC SERVER TO LIMECHAT UPDATE# Specifically, both tiers should have the MediaType of your capacity devices (such as SSD or HDD) and PhysicalDiskRedundancy = 2. The Performance tier should be ResiliencySettingName = Mirror, and the Capacity tier should be ResiliencySettingName = Parity. You may find it easiest to simply remove the existing tier template and create the two new ones. Remove-StorageTier -FriendlyName Capacity This will not affect any pre-existing volumes which were created by referring the tier template: it's just a template.
