Abstract:
1. A method of accessing a storage area network by real-time applications, comprising: receiving, at a plurality of local daemons, each executing on corresponding nodes, from real-time applications executing on the corresponding nodes, requests for reservation of a specified amount of bandwidth to access components shared in the storage area network; determining, by each of said local daemons, that each shared component of the each corresponding node along a path to each requested component has sufficient bandwidth for reservations from real-time applications executing the corresponding nodes; receiving, at a master daemon from the local daemons, the requests for reservation of a specified amount of bandwidth to access the components shared in the storage area network, scheduling, by the master daemon, access to the components shared in the storage area network by the real-time applications in response to the reservation requests received from the nodes, distributing to each local daemon a schedule of accesses requested by the real-time applications, determined during said scheduling by the master daemon; and allowing access to the storage area network by the real-time applications while limiting accesses to the components shared in the storage area network by each real-time application on each requesting node according to a corresponding schedule included in the schedule.
