Mission-Critical Business Continuity and Disaster Recovery for Oracle

• High Availability: Active/active data centers with zero RPOs and RTOs

• Disaster Recovery: Cost-effective DR for active/active data centers with point-in-time data recovery at a third, remote site

VPLEX with RecoverPoint

Maximizes available points in time (PITs) for disaster recovery

Integrated RecoverPoint splitter

Continuous data protection (CDP)

Continuous remote replication (CRR)

Continuous local and remote replication (CLR)

On-demand protection and recovery to any point in time

VPLEX

24/7 application availability

Simplified high availability management

Automatic failure handling & load balancing

Zero downtime maintenance

Simplified deployment of Oracle RAC on Extended Distance Clusters

Protection for multiple databases or application files as a unit with consistency groups

Increased infrastructure utilization

Oracle Database Architecture Oracle components

– Oracle Database 11g Release 2 Enterprise Edition– Oracle ASM – Oracle Clusterware

Oracle Extended RAC over VPLEX– Simplified management– Hosts connect only to their local VPLEX cluster– Hosts send I/O only once to the local cluster – dual writes not

required– No need to deploy Oracle voting disk and Clusterware on a third

site– Eliminates costly host CPU cycles consumed by host-based

mirroring– Protects multiple databases and/or applications as a unit

RecoverPoint Replication – Overview

Tests

Create a bookmark (named snapshot).

Recover database at Site C to bookmarked point in time.

Verify integrity of recovered database.

Fail over production from Site A to Site C.

Update database on Site C (now the production site).

Recover database at Site A to bookmarked point in time.

Verify integrity of recovered database.
