摘要： A cluster of computing systems is provided with guaranteed real-time access to data storage in a storage area network. Processes issue request 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.

摘要翻译： 提供了一组计算系统，保证对存储区域网络中的数据存储进行实时访问。 处理最初由与请求进程在同一节点上的守护程序处理的带宽预留的发出请求。 本地守护程序确定带宽是否可用，如果是，则在本地节点上的普通硬件中保留带宽，然后将共享资源的请求转发到集群的主守护进程。 主守护进程对群集共享的资源进行类似的确定和预留，包括存储区域网络中的数据存储元素，并允许对不超过总可用带宽的请求。
