My colleague Vincent has a post about the next version of esxReplicator. We are working at the same customer where we have implemented VI3 in their datacenters. At the moment, we are evaluating the use of ESX in remote sites. The infrastructure at those sites is rather basic. There is no SAN, no iSCSI so just local storage. To have some level of high availability, products such as vizioncore esxReplicator and Double-Take for VMware Infrastructure can be a solution.

I already posted a short review of the Double-Take product. Just like esxReplicator, it is easy to install and uses snapshots to perform replication. But I must say that esxReplicator has better scheduling options, a better GUI and reports its progress better. It can also send reports by e-mail so that you have some idea about what is going on.
