This explosion of data, referred to as big data in contemporary lingo, has created both the need and appetite for innovation in the storage arena. And so you have technologies such as multi-tiered storage, fluid data, and storage virtualization. The other need for efficient data management stems from the very nature of any data, which tends to lose its importance over time. There is a constant need to archive the old and keep the latest or most important data readily available. It is believed that data access follows the 80/20 rule--the most recent 20% of the data attracts 80% of the access.
From thin provisioning to replication to federation, virtualization options let you reclaim idle disks, speed recovery, and avoid lock-in. Get the new, all-digital Storage Virtualization Guide issue of Network Computing. (Free registration required.)
