Hitachi Bets Big on New Virtualization Platform

by Manu Sharma    Mar 04, 2009

With increasing awareness on greening of data centers, Hitachi Data Systems feels its concept of Control Unit Virtualization with thin provisioning will be recognized as the approach to storage virtualization in India.

Hitachi had recently announced the world’s first implementation of a large-scale, enterprise-class virtualization layer combined with thin provisioning software - representing the first time that customers can obtain the consolidation benefits of external storage virtualization and the power and cooling advantages of thin provisioning, in one integrated solution.

Talking to CXOtoday, Vivekanand Venugopal, vice president-solutions, products and services, Asia Pacific, Hitachi Data Systems, said, "With the combination of Hitachi’s control-unit virtualization and thin provisioning, organizations in India are positioned for improved storage economics by allowing for a lower total cost of storage ownership."

Control Unit Virtualization with thin provisioning can increase utilization, eliminate allocated but unused space, recover stranded storage, reduce redundant copies, increase access speed, and provide non-disruptive movement of data for multi-tiering, migration and replication.

A control unit based approach to virtualization is able to leverage all the rich functionality of the control unit and provide it as a service to enhance the functionality of less capable, lower cost, or legacy tiers of storage arrays. 

"This approach creates a powerful platform whereby storage services can be packaged and delivered across heterogeneous storage assets and be invoked by applications when needed," said Venugopal. 

Data over 60 days old on production systems will be considered toxic waste.  Structured data like data bases and semi-structured data like email and document management data are increasing dramatically as they are required to hold more data, longer, for compliance reasons. Corporate email quotas will increase from less than 200Mb to 2GB in order to support new knowledge workers and compete with free mail box offerings from Google and AOL.

An avalanche of unstructured data will be driven by RFID tags, smart cards, and sensors that monitor everything from heartbeats to border crossings. All these pressures will drive the need to archive data in order to reduce the working set of production data. Reducing the working set will reduce the need for storage capacity, on high energy-consuming production storage.

"Once it is contained in a managed archive, the data can be reduced through single instance store, de-duplication, copy on write, expiration, and deletion. This will call for new types of archiving systems that can scale to petabytes and provide the ability to search for content across different modalities of data," he said.
