METHOD AND APPARATUS FOR FAILOVER AND RECOVERY IN STORAGE CLUSTER SOLUTIONS USING EMBEDDED STORAGE CONTROLLER

摘要

Disclosed is a storage enclosure having a plurality of servers each having a storage controller. A second storage controller that is not part of any of the plurality of servers is embedded in the storage enclosure. The second storage controller is configured to process I/O commands directed to one of the server's storage controllers when a storage controller fails. In this manner, the storage controllers that are part of the servers may be fully utilized and still have a failover capability to the enclosure storage controller instead of another server storage controller that may also be fully utilized.
