Business continuity involves much more than recovering an IT infrastructure from a disaster. Today s business continuity solutions must keep organizations up and running despite unplanned interruptions. A comprehensive business continuity solution must address redundancy, data protection and recoverability of data according to the defined RPOs. With Dell storage replication solutions, organizations can now deploy a reliable disaster recovery and business continuity solution and at the same time reduce overall operating costs and complexity.

This whitepaper describes how to leverage Dell storage replication solutions to build a comprehensive disaster recovery plan for an Oracle Database involving both Compellent replication simulation dating and asynchronous options.

This enables you to choose the best replication option depending on the infrastructure and feasibility. The whitepaper also discusses the setting up of different replication methods between storage arrays for all the Dell storages and performing different disaster recovery test cases while validating the integrity of the Oracle Database.

The storage replication solutions discussed in this paper covers Dell Compellent, EqualLogic, and PowerVault storage systems. Dell storage replication solution creates an exact mirror copy of data on a remote system that Compellent replication simulation dating be mounted to rapidly recover from a failure.

It provides minimal asynchronous replication to zero synchronous replication data loss environment for applications. Dell s storage replication solution enables non-disruptive scheduled maintenance, DR testing and site workload reallocations.

In the Dell storage replication solution, Dell storage is integrated with centralized DR management products to automate the process of setting up and configuring recovery plans.

It also provides functionality to efficiently test these plans with no impact to production environments. The key benefits of Dell storage replication solutions are Optimized management and minimal storage capacity using thin provisioning for snapshots.

Ability to meet stringent Compellent replication simulation dating requirements for operational recovery. Advanced centralized recovery management integration.

Rapid recovery from planned and unplanned outages. In the following sections we discuss about Oracle Data Guard and Dell storage replication solutions for achieving the disaster recovery. If the production database becomes unavailable because of a planned or an unplanned outage, Data Guard can switch any standby database to the production role, minimizing the downtime associated with the outage.

There are two types of standby databases: A physical standby database is kept synchronized with the primary database though Redo Apply, which recovers the redo data, received from the primary database and applies the redo data to the physical standby database. A logical standby database is kept synchronized with the primary database though SQL Apply, which transforms the data in the redo, received from the primary database into SQL statements and then executes the SQL statements on the standby database.

The replication process can be synchronous or asynchronous as only replication can provide instant access to data and zero data loss minimal Recovery Point Objective or RPO and minimal Recovery Time Objective or RTO Synchronous Replication Synchronous replication guarantees data consistency zero data loss between replication primary and standby. This is achieved by ensuring write incident commitments at the primary and standby before a successful write acknowledgement is sent back to the host and its application.

In the Compellent replication simulation dating the write incidents cannot be committed at the source or destination, the write incidents are not be committed at either location to ensure consistency.
