Although Unity has been in the market for more than a year, until recently, I got a chance to configure a pair of Unity with file replication. If you were a VNX/Celerra user, there are 3 points you need to be aware to configure the file system replication on Unity.
- File System replication is bundled with NAS server replication
When replicating existing File Systems or VMware NFS Datastores with asynchronous replication, you must first configure replication for the NAS Server it is mounted on. It is not supported to replicate file system to a different Unity NAS server at the remote site.
When deleting a NAS server, the related file system must be deleted as well.
