DR Design and Test Results RecoverPoint compression ratio and

RPO results RecoverPoint/CE failover:

– Planned failover (Live Migration)– Unplanned failover (site disaster

recovery)

RecoverPoint/Cluster Enabler Setup1. Setup Hyper-V Cluster on Production site2. Configure one consistency group per virtual

machine and match names3. Finish consistency group initial replication4. Set the correct consistency group policy5. Use Cluster Enabler to configure the cluster

and add nodes from the DR site6. Test failover using Live Migration

Summary


Key Findings Desired performance to meet the needs of the

following application configurations:– SharePoint: 35,308 heavy users at 10 percent concurrency– SQL: 60,000 users with more than 4,000 SQL transactions

processed and 9,000 IOPS – Exchange: 10,000 concurrent users at 0.10 IOPS profile

Ease of provisioning and simplified management of the whole infrastructure

A comprehensive data protection solution with 100% automatic site failover and good RTO and RPO

– 3x compression ratio for most data– 3 second time lag and 18 minute freezing time to client

(worst case) during site failover in 85ms network latency
