Greetings,
I am doing some work for a customer, trying to optimize their current SRM set up.
Environment is set up in Production and DR, with 4 hour RPO. 10Gbps link with <1ms RTT, unshaped and near 0% packet loss.
During the execution/running of recovery plan/s, the Reprotect step is extremely time consuming.
For a 100GB Test VM, the initial Reprotect takes +-30mins. After failback, the 2nd Reprotect takes +-50mins, all this with no data changes.
This is same for Production VMs.
From all the documentation I have seen, vSR initiates a full sync between the Production and DR and does a checksum of the entire vDisk.
Is there anyway to work around this or speed up the checksum process? I've read that this has been optimised in vSphere Replication 6.0 onwards?
ESX, SRM, vSR are all version 6.0 upwards. vDisk is thin and Datastores are all VMFS.
