As I talk to users and vendors about their data protection schemes, I’ve noticed that many organizations protect their mission-critical applications by synchronously mirroring data from a primary array to a secondary array. They then replicate from the secondary array off-site, or off-campus, asynchronously to a third target. As I think about this architecture, I’ve started wondering if companies might not be better off mirroring to the primary and secondary arrays directly from their servers, rather than replicating synchronously.
