High-capacity disk drives
Various experts periodically predict that magnetic disk is approaching its capacity limit, as the magnetic dots can't get smaller or be packed closer together. Yet engineers always find a new way to stuff more data onto a disk.
Virtualization
Two years ago, we picked virtualization as one of the hot technologies for 2005. Well, as the old saying goes, "If at first you don't succeed, try, try again." (See "Report card on our 2006 predictions") In 2007, we expect virtualization to embed itself throughout the infrastructure. "When virtualization is used right, it will be everywhere," says GlassHouse Technologies' Foskett.
Thin provisioning
The best way to understand thin provisioning is to think about airline overbooking. By analyzing passenger behavior, airlines know that a certain number of passengers won't show up at departure. So they sell more seats than they have available.
