摘要： A system that, at a process checkpoint, pauses the process to copy the system state for the process and then copies pages of the process in memory to disk storage while the process continues to run. When a write to a page by the process is to occur that requires a translation from a virtual address to a physical address the write is intercepted. The page that is being modified is duplicated and then the process is allowed to modify the page and continue. The duplicate page is then stored as part of the checkpoint copy.

摘要： A cluster of computing systems is provided with guaranteed real-time access to data storage in a storage area network. Processes issue requests for bandwidth reservation which are initially handled by a daemon on the same node as the requesting processes. The local daemon determines whether bandwidth is available and, if so, reserves the bandwidth in common hardware on the local node; then forwards requests for shared resources to a master daemon for the cluster. The master daemon makes similar determinations and reservations for resources shared by the cluster, including data storage elements in the storage area network and grants admission to the requests that don't exceed total available bandwidth.
