Leveraging VNX replicator allows you to use your existing WAN link to sync file systems with other VNX arrays. VNX only requires you to enable the Replication license of an offsite VNX and the use of your existing WAN link. There is no additional hardware other then the replicating VNX arrays and the WAN link.
VNX Replicator leverages checkpoints (snapshots) to record any changes made to the file systems. Once there are changes made to the FS the replication checkpoints initiates writes to the target keeping the FS in sync.
Leveraging Replicator with VMware NFS DS will create a highly available virtual environment that will keep your NFS DS in sync and available remotely for whenever needed. VNX replicator will allow a maximum of ten minutes of “out-of-sync” time. Depending on WAN bandwidth and availability, your NFS DS can be restored ten minutes from the point of failure.
The actual NFS failover process can be very time consuming: once you initiate the failover process you will still have to mount the DS to the target virtual environment and add each VM into the inventory. When you finally have all of the VMs loaded, next you must configure the networking.
Fortunately VMware Site Recovery Manager SRM has a plug-in which will automate the entire process. Once you have configured the policies for failover, SRM will mount all the NFS stores and bring the virtual environment online. These are just a few features of VNX replicator that can integrate with your systems
