IBM upgrades business continuity storage engine

IBM has announced enhancements to its main storage virtualisation engine software to help with customers’ business continuity plans.

The IBM System Storage SAN Volume Controller 4.1 (SVC) now includes a number of new technologies, including one that is designed to help organisations virtualise their infrastructures more efficiently and at lower costs over longer distances. 

In the wake of regional disasters, such as Hurricane Katrina, said IBM, customers are seeking to place data centres that share resources at greater distances apart than in the past, including in other cities, other states, or even in other countries. 

A new global mirroring function is designed to help customers virtualise data at locations of greater than 100 miles more quickly and more cost effectively than previously.

The Global Mirror functionality is designed to provide long-distance asynchronous remote replication for business continuity and disaster recovery at nearly unlimited distances. 

Built on the Metro Mirror code base already offered in SVC, Global Mirror is designed to maintain a consistent secondary copy of data. 

With SVC 4.1, Metro and Global Mirror are delivered as a single feature, allowing for implementation flexibility and no additional licensing fee for existing Metro Mirror users. 

IBM’s replication service allows a client to mix and match arrays between primary and secondary sites to help reduce overall costs.

In addition to the business continuity enhancements, SVC 4.1 now also supports four gigabits per second (Gbps) environments, and has extended its capabilities to virtualise data on nearly 80 different disc systems.

IBM SVC 4.1 will be available from 23 June, with a combined hardware and software list price starting from $42,500 (£25,000).
