DUAL CLASS OF SERVICE FOR UNIFIED FILE AND OBJECT MESSAGING

Abstract:

A storage system has priority queues for real time-class file system messaging and backup-class file system messaging. The storage system includes servers, coupled as a storage cluster, storage devices and a network coupling the servers and the storage devices. The servers have priority queues. The servers operate the priority queues for messaging from the servers to the storage devices via the network in accordance with a real time-class file system and a backup-class file system. A first subset of the priority queues has higher priority on the network for real time-class file system messaging of at least one type. A second subset of the priority queues has lower priority on the network for backup-class file system messaging of at least one type.
