Does anyone know why Unity Connections has a requirement for it's vDisks to be set to independant-persistant mode? I don't see this requirement for any other UC application and would prefer to not set it in this mode as it prevents us for taking a snapshot when the machine is shutdown. I know that snapshots are not officially supported, but it is a great back-out plan in the case of doing maintenance off hours and deleting the snapshot before using the VM in production.
Expanation of Independent Disks:
Independent Disks are not affected by snapshots.
Persistent - Changes are immediately and permanently written to the disk.
Where I found the Cisco requirements:
http://www.cisco.com/en/US/docs/voice_ip_comm/connection/8x/requirements/8xcucsysreqs.html
"All virtual disks assigned to the Connection virtual machine must be configured in independent-persistent mode, which provides the best storage performance."
