VMs with Duplicate BIOS UUIDs when using Datrium Cloning
VMware VMs have two UUIDs – BIOS UUID and instance UUID.
VirtuCache doesn’t support Write-Back policy where multiple VMs in the same vCenter share the same BIOS UUID, even if these VMs have different Instance UUIDs.
When using the cloning feature in Datrium (now end of lifed), the cloned VM and the original VM will share the same BIOS UUID.
For VirtuCache to support Write-Back caching of such VMs, follow this Virtunet KB to assign a unique BIOS UUID to these cloned VMs.
