Abstract: A system facilitates access to data in a network and includes a cache that stores instructions. A processor executes the instructions including: caching processing configured to integrate caching into a local cluster file system, and cache local file data in the cache based on fetching file data on demand from a remote cluster file system. The cache is visible to file system clients as a Portable Operating System Interface (POSIX) compliant file system. Applications execute on a multi-node cache cluster using POSIX semantics via a POSIX compliant file system interface. Data cache is locally and remotely consistent for updates.

Abstract: A method for managing storage allocation includes adaptively determining, by a storage device processor, a region width across disk spaces for a group of storage devices that is inversely proportional to a number of nodes sharing a particular storage device. An adaptive storage device allocation region of the particular storage device is created based on the determined region width across the disk spaces for the group of storage devices.

Abstract: Scalable caching of remote file data in cluster file systems is provided. One implementation involves maintaining a cache in a local cluster file system and caching local file data in the cache by fetching file data on demand from the remote cluster file system into the local cached file system over the network. The local file data and metadata corresponds to the remote file data and metadata in the remote cluster file system. Updates made to the local file data and metadata are pushed back to the remote cluster file system asynchronously.

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.
