What is Business Continuity?

y Business Continuity is the preparation for, response to, and recovery from an application outage that adversely affects business operations

y Business Continuity Solutions addresses systems unavailability, degraded application performance, or unacceptable recovery strategies

Business Continuity remains at the top of every executives priority list. Yet executives find themselves in a financial tug-of-war between business continuity solutions and other projects competing for the limited resources. Fundamental to business continuity is the need to understand an organizations practices relative to the protection, availability, and usability of data.

Failures happen - Hardware, Software, Nature Disasters etc. Downtime has a significant impact, the cost is more than just financial loss. What can we do to avoid downtime or minimize the length of time we are down? EMC offers Business Continuity Solutions that help address common failures or outages.

SRDF Recovery Point Objectives (RPO)

Recovery Point Objective (RPO).This refers to the maximum amount of data loss an application can tolerate as measured in time. In other words, the amount of data loss that can be tolerated (cost of transaction versus risk).

Individual customer business needs drive the technology chosen to meet specific recovery point objectives. This is also known at RPO (Recovery Point Objective)

Data Characteristics that Influence Data Storage Decisions

Several factors affect the value of data including: Legislation, which can mandate how long the data must be accessible, and by whom Business processes that are tied to points in time (book closing, quarterly reports, tax deadlines, billing cycles, and so on)

Business processes that are tied to customer satisfaction Service levels associated with the data as its purpose changes. For example, data can start out as transactional, then migrate to billing, then reporting and customer service, then to scoring data for a marketing system, then finally to archival.

The usefulness of data to the business will vary over time, and hence the necessity to have immediate access to the data will change. The decisions about where data is placed in the storage infrastructure and the methods used to protect that data are fundamentally driven by three factors: The time required to access the data relative to the cost of the access (that is, usefulness to the business versus cost)

Recovery Time Objective (RTO).This refers to the maximum time a company budgets to bring an application back online in the event of a disaster. In other words, the time it takes to recover the data once a disaster or other recovery event is declared (risk versus cost). Each change in data placement and protection criteria represents a stage in the life cycle of the data and is directly related to the usefulness or importance of the data in keeping the business functioning.

What are the SRDF Solution Sets?

y Symmetrix Logical Volumes are mirrored between geographically dispersed locations

y Maintain real-time physically separate mirrors of data with SRDF

y Maintains near-real-timephysically separate mirrors of selected volumes with SRDF/A (Asynchronous) or SRDF/AR (Automated Replication).

y Continue running through events such as individual drive/link failures

y Mirror copy can be split and used for disaster recovery or business continuance applications

SRDF/AR

The SRDF family of software is the most powerful suite of remote storage replication solutions available for disaster recovery and business continuity. It leverages high-end Symmetrix storage architecture to offer unmatched deployment flexibility and massive scalabilityso you can meet mixed service level requirements with minimal operational impact. The most widely deployed set of high-end remote replication solutions, the SRDF family is installed in tens of thousands of demanding environments worldwide. And only the SRDF family provides cross volume and storage system consistency, tight integration with industry-leading applications, and automated management for simplified usage.

EMC has several remote replication offerings for various service level requirements. For zero data exposure, EMC offers the industry leader for synchronous mirroring: SRDF. However, as with any synchronous solution, there are characteristics that must be understood. Distance is limited by application time-outs and bandwidth must be sized for peak workload at all times. SRDF/Asynchronous is a solution for service level requirements that need Recovery Point Objectives (RPO) in the seconds-to-minutes area. SRDF/AR delivers solutions that combine SRDF with TimeFinder to create single-hop and multi-hop environments for specialized needs.

These solutions offer different RPOs and have different requirements for bandwidth, supported distances, etc. No matter what your requirements are, EMC can help deliver the right Remote Replication Solution.
