Improving VMware Disaster Recovery with EMC RecoverPoint

This configuration requires that the VMware virtual machines utilize RDM/P volumes,

or that VMware Converter is used to convert these volumes to VMFS.

Figure 13. Physical-to-virtual replication

In physical-to-virtual replication, each physical machine is mapped to a RecoverPoint

consistency group. Each of the LUNs accessed by the production machine becomes a

replication set in the consistency group. Separating the physical server replication by

consistency group allows for either a planned failover or for the use of the replicated

image in the ESX machine for purposes such as testing, data mining, and object

recovery. The target virtual machine can be either local, as shown in the previous

figure, and/or remote. With RecoverPoint there is no need to have the replicas reside

in the same array, array family, or volume type as RecoverPoint will manage the

physical replication between dissimilar arrays.

The ESX server is built and configured with virtual machines that match the

application configuration of the physical machines. The virtual machines are not

running during normal operations, and are only powered on to access new data. The

basic flow is as follows:

1. Select the appropriate image using either a point-in-time selection or a bookmark

selection requesting physical image access. This will cause RecoverPoint to roll

back the replica image to the selected point-in-time image.

2. Once the rollback is completed, the selected image LUNs will be unmasked and

will become visible to the ESX server.
