Abstract: A process and system for virtually managing enclosures. A process determines whether a system includes an enclosure processor, a virtual enclosure processor, or both an enclosure processor and a virtual enclosure processor. The process receives a command by a virtual enclosure processor if it is determined that the system includes the virtual enclosure processor. The virtual enclosure processor manages a peripheral in an enclosure. Additionally, a process activates a virtual enclosure processor in a system including a real enclosure processor. The virtual enclosure processor receives a command. The virtual enclosure processor controls a peripheral.

Abstract: A method according to one embodiment may include receiving an input/output (I/O) request to write data stored on at least one target device comprised in at least one local storage array. The method of this embodiment may also include generating one or more I/O transactions capable of writing data on at least one target device comprised in at least one remote storage array. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Abstract: Provided is a method, system, and article of manufacture for generating topology information including information on local interfaces in a device and remote interfaces in at least one remote device that connect to the local interfaces identified in the topology information. For each connected remote interface, a determination is made of a device type of the one remote device including the remote interface. For each local interface connecting to one remote interface in one remote device of a specified device type, communication initiated with the remote interface to access remote topology information from the remote device indicating devices attached directly and indirectly to the remote device.

Abstract: In one embodiment, a method is provided that may include determining, at least in part, at an intermediate station one or more locations in storage devices of one or more respective portions of check data and/or other data. The check data may be generated, at least in part, at the intermediate station based at least in part upon the other data. This method also may include determining, at least in part, at the intermediate station, based at least in part upon forwarding information, one or more ports of the intermediate station via which to forward one or more packets. The one or more packets may be generated at the intermediate station based at least in part upon one or more other packets received via one or more other ports of the intermediate station. The other packets may comprise the check data and/or other data.
