Improving VMware Disaster Recovery with EMC RecoverPoint

recommended that allows single guest OS replication granularity, thereby expediting

failover and test activities.

In the combined VMFS configuration, two RecoverPoint consistency groups will be

defined. The first RecoverPoint consistency group contains all of the existing LUNs (or

VMFS volumes) with the entire set of guest OSs and their data. The second

RecoverPoint consistency group, or

standby

, contains storage volumes at each site

that are at least as large as the largest combined guest OS image and related virtual

data disks. Although this group is configured for RecoverPoint replication, it does not

replicate any data as long as there are no writes taking place at the source site. When

needed, any guest OS with its data can be moved to this storage space, and

individually replicated to the target site. As a result, it is also possible to test and, if

desired, fail over this guest OS independently from the other guest OSs.

Physical-to-physical replication with local virtualization

In a physical-to-physical configuration the customer is looking to migrate from a

physical to virtual environment either for their production data center or for their

disaster recovery data center. Either the local replica is to be presented to a

virtualized environment or the remote replica is to be presented to the virtualized

environment. The example below uses RecoverPoint concurrent local and remote

data protection. This differs from the local physical-to-virtual replication

configuration that uses RecoverPoint continuous remote replication. This example

adds the physical machines that exist in the disaster recovery site. Since physical

machines exist, the virtualized machines access the data in RDM/P mode.
