Abstract
Embodiments of the invention relate to storage allocation in a storage system. One embodiment includes generating a request for storage space allocation in a particular storage device by a first node. An owner node associated with the particular storage device is determined by a first allocation client associated with the first node. The request is sent by the first allocation client to a second allocation client associated with the owner node. A storage device allocation region of the particular storage device is created, the allocation region comprising a height proportional to storage devices the owner node and the second allocation client are coupled with, and a width that is inversely proportional to a number of nodes sharing the particular storage device.
