Fault tolerant data storage system
摘要:
A fault tolerant data storage system and related method are described for effectively failing over a storage device from one storage controller to another storage controller. The storage system generally includes at least two storage controllers for coupling to a processor and at least one storage device. A failover manager is in communication with the storage controllers and the storage device. The failover manager assists failing over of the storage device by allowing only one of the storage controllers having ownership to access the storage device at any one time. In one embodiment, the failover manager maintains a list of recent requests that have been committed to the storage device so that it can be used during failover to assist the surviving controller to complete the uncommitted requests properly.
