Data Storage Handbook:
Learn all about self-service storage
Self-service storage is the ability to delegate volume provisioning of storage to business units in the organization. Learn how this technology can make your life easier.
Traditional storage management introduces a lot of waste. Your customers may leave anywhere from 30% to 50% of their allocated space unused. This is hardly trivial -- for every 10 TB purchased, 3 to 5 TB are left unused because of inefficient provisioning. Thin provisioning overcomes these problems, improving storage utilization and saving money.
Is thin provisioning truly a miracle technology? Not really. It's not a tool that can magically provide you with more capacity than you purchased. However, it does let you allocate only what's accessed while allowing the host to think it has access to everything it sees.
Learn how thin provisioning works, as well as its benefits and drawbacks, so you can decide whether it is right for your storage environment.
