Improving VMware Disaster Recovery with EMC RecoverPoint

3. From the ESX Server console, scan for the new LUNs and then register them with

the appropriate virtual machine.

4. Power up the virtual machine, which will see the point-in-time image data. At this

point RecoverPoint tracks the reads and writes to the image so that they can be

backed out when image access is completed.

After step 2 completes, an array snapshot, such as provided by an EMC TimeFinder

BCV or EMC SnapView™ clone, can be created from the replica LUNs, and then

RecoverPoint would be informed that image access is completed. Once RecoverPoint

resumes processing the user would present the snapshot to the ESX server for use by

the virtual machines. Alternatively, these snapshots can be used by VMware

Converter to import the data to existing VMFS volumes.

Virtual-to-virtual replication

In this usage case the customer has fully migrated to a VMware infrastructure for their

production and disaster recovery sites. At the disaster recovery site, they are taking

advantage of the server and storage consolidation capabilities of VMware and

RecoverPoint. The customer has fully deployed a VMware ESX Server environment

using VMFS deployed with either a CLARiiON-based splitter or an intelligent fabric

write splitter. This configuration can also be supported using a Windows-based

KDriver when SAN LUNs are attached as RDM/P volumes.

Figure 14. Virtual-to-virtual replication

If a VMFS is used, then the virtual machines are either configured to use a separate

VMFS volume for each machine or all of the virtual machines use the same VMFS

volumes. In the figure above, each virtual machine is assumed to have its own VMFS;

this allows for an individual virtual machine to be tested and/or failed over to the

disaster recovery site without impacting the remaining virtual machines. When

multiple guest operating systems (OSs) are distributed over a limited set of LUNs,

such as combined into one or more VMFS volumes, a special configuration is
