Abstract: There is described a method for optimising the distribution of data objects between caches in a cache domain of a resource limited network. User requests for data objects are received at caches in the cache domain. A notification is sent from each cache at which a request is received to a cache manager. The notification reports the user request and identifies the requested data object. At the cache manager, object information including the request frequency of each requested data object and the locations of the caches at which the requests were received is collated and stored. At the cache manager, objects for distribution within the cache domain are identified on the basis of the object information. Instructions are sent from the cache manager to the caches to distribute data objects stored in those caches between themselves.

Abstract: A network storage controller uses a non-volatile solid-state memory (NVSSM) subsystem which includes raw flash memory as stable storage for data, and uses remote direct memory access (RDMA) to access the NVSSM subsystem, including to access the flash memory. Storage of data in the NVSSM subsystem is controlled by an external storage operating system in the storage controller.

Abstract: Electronic information is made more readily available to one or more access requesters based on an anticipated demand for the electronic information using a process, system or computer software. For instance, electronic information stored on a first storage medium is identified for transport (e.g., in response to a request of at least one of the access requesters), and the electronic information is transported accordingly. Afterwards, a determination is made to store the electronic information on a second storage medium that is more accessible to the access requesters than the first storage medium.

The anticipated demand is determined based at least on information that is not particular to any single access requestor. The electronic information then is stored on the second storage medium and the access requesters are provided access to the electronic information from the second storage medium.

Abstract: Methods, apparatus, and computer-accessible storage media for remotely updating an executing process that receives I/O requests on I/O port(s), stores write data to a write log on local storage, and uploads data from the write log to remote storage. An update for the process is detected and downloaded, and an updated process is instantiated from the update. The current process is directed to perform a shutdown for update during an update window. In response, the current process saves its current configuration, flushes an in-memory portion of the write log to local storage, and releases its I/O port(s). The updated process loads the saved configuration, detects that the port(s) have been released, and starts accepting I/O requests on the ports. During flushing, the current process flushes current data in memory while continuing to append new write data, stops accepting new write requests, and then flushes the new write data.

Abstract: A data storage server is programmed with common software modules for management, version control, and scheduling of replication of data storage objects of multiple data storage object types. The multiple data storage object types include iSCSI LUNs, file systems, virtual servers, directories, and files.

The scheduler controls the timing of snapshot creation and deletion, and replication transmission to one or more remote destinations. The scheduler may ensure that a replica of a data storage object is out-of-sync with the original of the data storage object by no more than a specified amount of time.
