Embodiments of the present invention provide methods and systems for leadership allocation in a distributed computer system. In certain embodiments of the present invention, a leader-election-service process runs within each node of a distributed computer system, together cooperatively providing a distributed-leader-election service. The distributed-leader-election service employs a distributed consensus service to manage distributed state information related to roles and leadership allocation within a distributed computer system. Client processes within each node interface with the leader-election-service process of the node in order to assume leadership of particular roles within the distributed computer system. Leadership-allocation management is thus centralized, within each node. In alternative embodiments, the distributed-leader-election service may be implemented as a collection of library routines that run in the context of client processes.

A method for managing bandwidth allocation in a storage area network includes receiving a plurality of Input/Output (I/O) requests from a plurality of client devices, determining a priority of each of the client devices relative to other client devices, and dynamically allocating bandwidth resources to each client device based on the priority assigned to that client device.

Method and apparatus for dynamically managing bandwidth for clients in a storage area network

A method for managing bandwidth allocation in a storage area network includes preparing a policy that defines access parameters for two or more groups of client devices that are grouped according to priority in accessing network resources.
