What does thin provisioning do in storage efficiency?

• A. Increase performance
• B. Allocate storage on demand to avoid over-provisioning
• C. Duplicate volumes
• D. Reclaim licenses

Answer: (B)

Thin provisioning is a storage efficiency technique that presents more capacity to hosts than is physically available by deferring the actual allocation until data is written. This enables you to allocate storage on demand from a shared pool, so you don’t reserve the full size upfront and end up wasting space. That on-demand allocation is the essence of avoiding over-provisioning and making better use of available storage. It isn’t about boosting performance, creating duplicates, or reclaiming licenses. In practice, you can grow capacity by adding disks to the pool and then allocate to volumes or LUNs as data actually fills the space, which helps with capacity planning and faster provisioning—though it requires monitoring to prevent running out of physical space and may involve space reclamation features on some systems.
