In today's world, prudent IT administrators prepare to recover from two types of disasters as part of a complete Business Continuity and Availability (BC&A) plan. The first is a localized disaster, affecting a building or a small set of buildings. The second is a wide-area disaster, such as a hurricane or a regional power outage. Enterprises must replicate data to alternate data centers, located at a variety of distances from the primary data center, while maintaining acceptable data currency standards. Until now, available remote replication technology has involved drawbacks. Synchronous remote replication solutions are designed to maintain total data currency, but can induce application performance degradation when replicating over long distances.
