摘要
Systems and methods are disclosed which facilitate management of thin provisioned data storage. Specifically, portions of thinly provisioned data stores may be deallocated when they contain invalid data, such as data deleted by a user. A user may transmit notifications, which may include write requests corresponding to a defined bit pattern, to a provider of the data store (or to the data store itself) that data has been deleted. A management component may modify the data store, or metadata corresponding to the data store, to reflect the deletion. The management component may further monitor portions of the data store to determine whether individual portions contain entirely invalid data. If so, the portion may be deallocated from the thin provisioned data store, resulting in more efficient thin provisioning. Deallocation may be enabled even where deletion notifications from a user do not correspond directly to allocated storage portions.
