Method and system for efficient allocation of storage

A method for efficiently allocating storage in a storage system, the method comprising:

• receiving, by an infrastructure manager, a request for storage from a first storage operating entity;
• identifying, by the infrastructure manager, from entries in a pagebin, a pagelist with sufficient available storage to satisfy the request;
• locking, by the infrastructure manager, the pagebin while assigning the identified pagelist to the first storage operating entity;
• upon a commitment of the identified pagelist by the first storage operating entity, (1) unlocking, by the infrastructure manager, the pagebin, and (2) identifying, by the infrastructure manager, from the entries in the pagebin, a second pagelist with sufficient available storage to satisfy a request from a second storage operating entity.
