Re-think backup requirements with clustered storage

It will take some years before the market decides what combinations of storage topologies are optimum, as vendors and customers try different approaches to melding file system, disk storage, tape storage and network technologies. Organizations should ensure that experience is gained with multiple storage approaches, including emerging clustered designs for so-called cloud computing (e.g. Google File System, EMC's Hulk/Maui, etc). Such new architectures support an always-on approach and presume failure of components such that traditional backup may not be necessary.

These technologies should be tested at all stages from application design to operational implementation. Storage needs to be organized to encourage different approaches, including outsourcing storage to third parties.

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.
