Replicator Spans Platforms

摘要

Data replication is useful in so many ways. In addition to its critical role in disaster recovery, it can consolidate data from multiple servers or data stores, or distribute data to multiple stores, allowing branch offices to access local copies of data and thus reduce WAN traffic. Although many data storage vendors provide replication functions, they typically work only with that vendor's products, often require extra components to replicate over a TCP/IP network, and may only work between specific models of storage devices. Fibre channel-based systems, such as Maxxan's MXV320 Intelligent Application Switch (infoworld .com/525), can provide transparent data replication and work between different types of systems, but they are relatively expensive, starting at about $30,000.
