In an effort to speed data centre replication over wide area networks, Cisco Systems (NASDAQ: CSCO) has put its WAN optimization technology for branch offices into its top-of-the-line acceleration appliance.
The company said a new version of the Wide-Area Application Services (WAAS) software that runs its WAE-7341 and WAE-7371 Wide Area Application Engine appliances for data centres now come with a replication acceleration mode.

“In terms of return on investment, you’re now able to minimize the WAN bandwidth that’s used for data replication,” said Marcus Phipps, Cisco’s senior marketing manager for data centre solutions.
Most large organizations have a separate data centre for backup protection, he said, or they might have several data centres that feed into a central centre. If big enough, replication could take days, even over an OC-3 or DS-3 link. The replication acceleration technology can “dramatically shrink” replication times over a WAN, he said. As a result, organizations can schedule more replications in a given period, which will make the data more resilient.

This does sound interesting, the closer we can move to data center virtualization, where my application follows the sun, or even the cheapest place to run is an exciting concept. That I could fail workloads/data centers between sites in line with business or IT requirements could bring dramatic improvements in the ability to do preventative maintenance, be more efficient with our resources, and be more responsive or on demand to the business need.
