IBM introduces replication technology

IBM Tuesday announced a business continuity technology to replicate data over long distances as much as three times faster than competing technologies.

Called the TotalStorage Global Mirror for the TotalStorage Enterprise Storage Server (ESS), the technology lets customers back up data over distances of more than 180 miles with a latency of only three to five seconds.

Global Mirror uses asynchronous peer-to-peer remote copy technology and allows massive data transfers between two locations linked by Fibre Channel. It can write data at 23,000 I/O's per second.

The Global Mirror technology is available as part of the IBM TotalStorage Resiliency Family, which also includes FlashCopy, Peer-to-Peer Remote Copy and the Geographically Dispersed Parallel Sysplex software.

The company's Synchronous Peer-to-Peer Remote Copy technology has been named Metro Mirror. It can synchronously or semi-synchronously replicate data over a distance of as much as 180 miles.

Both Global Mirror and Metro Mirror start at US$23,000. Global Mirror is expected to be available in May.
