NetApp MetroCluster Software Cost-effective is an integrated high-availability storage cluster and site failover capability.

NetApp MetroCluster is an integrated high-availability and disaster recovery solution that can reduce system complexity and simplify management while ensuring greater return on investment. MetroCluster uses clustered server technology to replicate data synchronously between sites located miles apart, eliminating data loss in case of a disruption. Simple and powerful recovery process minimizes downtime, with little or no user action required.

At one company I worked at they used the NetApp snap mirror feature to replicate data across long distances to multiple datacenters. They had a very fast backbone and it worked well. The issue with NetApp is always one of cost, but if you can afford it, it's a good option.
