Like Sean, we use SRM with array based replication, and we haven't seen anything like that. But I very rarely have SQL servers as VMs; we prefer them physical, due to the disk activity. We do array-based replication, and use EMC's RecoverPoint appliance, to keep the 2 arrays replicated (over a 10G link, which is sweet, let me tell you ...)
We just last month did a DR test, and the SRM worked perfectly for 145 VMs. (well, once we realized you should't replicate the placeholder LUN, anyway ....)
