Improving VMware Disaster Recovery with EMC RecoverPoint

Finally, with RecoverPoint the distance between the sites is not a limit, since

RecoverPoint replicates the data asynchronously but maintains the write-order

consistency at the remote site, ensuring that all replicas remain fully consistent.

Integration with RecoverPoint

VMware vCenter Site Recovery Manager is designed as a plug-in to VMware vCenter

Server so that the SRM disaster recovery tasks can be executed inside the same

management tool as other VM administration tasks such as creation, migration, and

deletion. VMware vCenter SRM is highly automated and is responsible for the setup,

test, and recovery workflows for disaster recovery automation. SRM enables you to

accelerate recovery and ensure successful recovery by automating the recovery

process and eliminating the complexity of managing and testing recovery plans.

VMware vCenter SRM eliminates complex manual recovery steps and removes the risk

and worry from disaster recovery.

VMware vCenter SRM reduces the RTO for disaster recovery and relies on block-based

replication, such as is provided by RecoverPoint, to reduce the RPO for disaster

recovery. To implement replication, a RecoverPoint storage replication adapter for

VMware is used to map the VMware vCenter SRM requests into the appropriate

RecoverPoint actions. The RecoverPoint adapter was developed, qualified, and

supported by EMC. The RecoverPoint adapter can be downloaded from the VMware

site and is also available from EMC.

All of the benefits of RecoverPoint discussed in this paper also apply when VMware

vCenter SRM uses RecoverPoint for replication. This includes the use of array-based

write splitters, heterogeneous storage, and policy-based replication. SRM is

designed for site-to-site replication, as such it only works with remote replication as

provided by RecoverPoint CRR, or if continuous local and remote data protection is

being used, SRM will only operate with the remote replica copy. The local (or CDP)

copy of a CLR consistency group will be unaffected by the SRM operations and will
