Storage virtualization: It’s ready, are you?
This article is part of the Vol. 10 Num. 6 August 2011 issue of Storage magazine
Adoption of storage virtualization has been accelerating as some of the early obstacles to implementation have fallen by the wayside. There’s a wide choice of mature products whether you decide to deploy storage virtualization at the array or in the network. While there may be some dispute over an exact definition, storage virtualization is generally considered technology that provides a flexible, logical arrangement of data storage capacity to users while abstracting the physical location from them. It’s a software layer that intercepts I/O requests to the logical capacity and maps them to the correct physical locations. The most basic implementation of storage virtualization is at the host level, where a logical volume manager allows the simple provisioning of storage capacity to apps and users. While also implemented with file storage systems, block storage virtualization is more commonly implemented due to the complexity of LUN management and the requirements for flexibility in storage provisioning, especially in multi-user ...

Our survey finds more firms are relying on automated processes to back up their remote offices, and more backup data is making it back to the main data center than ever before.
In a relatively short time, data deduplication has revolutionized disk-based backup, but the technology is still evolving with new applications and more choices than ever.
Adoption of storage virtualization picks up as early obstacles to implementation are overcome. Mature products exist to deploy storage virtualization at the array or in the network
Storage technologies may sometimes seem a little stodgy and out of date, but there’s plenty of technical development going on at both the big storage vendors and smaller upstarts.
