A method and system for providing a shared data resource coordinator within a storage virtualizing data processing system is disclosed. According to one embodiment of the present invention, a first node of a plurality of nodes is configured to process requests to access a shared data resource on behalf of the plurality of nodes, where the plurality of nodes includes a logical volume configuration server configured to present a logical volume to one or more logical volume configuration clients. A second node is then selected from the plurality of nodes and configured to process requests to access the shared data resource on behalf of the plurality of nodes.

A logical container may be created to facilitate the quick and efficient migration of one or more virtual machines from a source server to a destination server. The logical container may contain all of the files and state information related to the one or more virtual machines. The one or more virtual machines may be migrated by dismounting the logical container from a source server and mounting the logical container to a destination server. A management service may be include to facilitate batch migration of multiple virtual machines from a source server to a destination server.

Systems and methods for implementing volume sets in a storage system. According to a first embodiment, a system may include a volume server, a first and a second client computer system, and a plurality of physical block devices. The volume server may be configured to aggregate storage in the plurality of physical block devices into a plurality of logical volumes, wherein a given logical volume includes storage from at least two physical block devices, to distribute a first subset including at least two of the plurality of logical volumes to the first client computer system for input/output as a first volume set configured to be accessed as a single logical device, and to distribute a second subset including at least two of the plurality of logical volumes to the second client computer system for input/output as a second volume set configured to be accessed as a single logical device.

An operating system is simulated to run in conjunction with a native operating system, allowing processes originally developed for the operating system being simulated to be ported to the environment of the native operating system with a minimum of effort. Ported processes will consume resources of both operating systems, the native operating system and the simulated operating system, that are cleaned or otherwise removed when the ported process ends by setting up a monitoring facility to detect when the ported process ends. When that occurs, the simulated operating system resources are cleaned by a cleanup process that impersonates the ported process that ended. The cleanup process is also monitored, so that when it ends, additional cleanup processes are called into action to cleanup the system resources of the remaining simulated operating system used by the ported process that ended, and the system resources used by the cleanup process.

A method and process for providing a memory dump of less than the entire contents of memory is provided. The memory locations to be dumped are selected on the basis of recency of use, so that there is a high probability that portions of memory needed for analysis or evaluation of the computer system will be included in the selective dump. Preferably, the select ion is made on the basis of information or hardware which is already provided in the computer system. In one preferred embodiment, memory to be dumped is selected on the basis of memory locations encoded for by a translation lookaside buffer.
