Hi Chad, it is correct both that we use vSphere snapshot technology to do replicas as we do for backups, and also that you can leverage NetApp storage snapshots to initiate a replica at source to lower their impact. Have you done any research on the performance to figure out why the loss of connection is happening even when using storage snapshots? There may be some performance issue that can be improved.
For the test, it's almost correct, but we do not snapshot memory, so you do not need to select any of those two options. A suggestion can be to look at the backup job usins already storage snapshot, or even look at vcenter during a backup, and see the time it takes between snashot creation and commit. This is the time it will take even during a replication. Once you know that value (probably around one minute) you can test the impact of a replica during the day by going into vcenter, take a snapshot of the ERP machine, wait for the same amount of time, and then ask vcenter to delete the snapshot. Look if the ERP machine is having any freeze or slowdown.
