Abstract
Apparatus and methods for managing storage. A storage system may receive a request from a host, for example, to allocate n blocks of storage. The storage system may allocate m blocks of physical storage, where m<n, and indicate that the request completed successfully. In various embodiments, m>zero (0) or m=zero (0). The storage system may receive a request to access a block j of the requested blocks of storage, m<j<n, and accessing the block j, in response to the request to access. Allocating the physical storage may include allocating m blocks of physical storage encompassing the block j. After the allocating, the storage system may receive a request to access a block j of the requested blocks of storage, m<j<n, access the block j and indicate that the request to access completed successfully.
