Hope for tape vendors lies with a dedupe standard

Users have adopted data deduplication as an important first step in facilitating the transformation to disk-based backup. Users should continue to drive their suppliers to greater support of standards that will improve users’ ability to manage their information liabilities and assets. However, they should not regard deduplication as a cure-all for out-of-control data growth. Dedupe is most effective in data backup and recovery applications, where large volumes of unchanged data are being stored over and over. In other applications, such as ERP and CRM, dedup will not offer major advantages.

Tape vendors must aggressively adopt deduplication technologies in their portfolios, initially integrating into a blended disk/tape offering (e.g. VTL's) and eventually applying similar capacity utilization techniques to tape controllers. Importantly, unless these techniques are developed as industry standards, tape vendors will be overwhelmed by aggressive disk marketing.

Virtualization Energizes Cal State University

John Charles is the CIO of California State University, East Bay (CSUEB) and Rich Avila is Director, Server & Network Operations. In late 2007 they were both looking down the barrel of a gun. The total amount of power being used in the data center was 67KVA. The maximum power from the current plant was 75kVA. PG&E had informed them that no more power could be delivered. They would be out of power in less than six months. A new data center was planned, but would not be available for two years.

Featured How-To Note

Storage Virtualization Design and Deployment

A main impediment to storage virtualization is the lack of multiple storage vendor (heterogeneous) support within available virtualization technologies. This inhibits deployment across a data center. The only practical approach is either to implement a single vendor solution across the whole of the data center (practical only for small and some medium size data centers) or to implement virtualization in one or more of the largest storage pools within a data center.
