Tech That Should Be on Your Company's Radar for 2012

The company that can best serve its customers will be the most likely to succeed--and that entails knowing as much as possible about your customers . Hadoop is a system designed by the Apache Foundation to process large amounts of data. As organizations accumulate terabytes of data about customers, business processes, partners and more, the model of a single database running on a single server becomes less useful. Hadoop runs across multiple systems at once, allowing bigger data sets as well as separate search engines for different purposes.
4. Storage Virtualization
Storage virtualization allows for many useful features in storage area network systems . Putting a layer of virtualization between the servers allows for thin provisioning, automatic tiering of storage, instant snapshots, and deduplication. Since there is no direct correlation between the volume a server mounts and the physical storage being used, a volume may actually be spread across multiple systems. This allows for the most-used files to be stored on the fastest drives (auto-tiering), for volumes to be expanded as needed (thin provisioning), for a system to store only one copy of each unique file (deduplication), and for instant copies of volumes to be made for backups, system recovery, and other uses (snapshots).
