Abstract
In one embodiment, a system includes a cache storage device, a back-end storage device, and a processor and logic integrated with and/or executable by the processor. The logic is configured to receive indication of failure of a primary cache server at a secondary cache server, the primary and secondary cache servers being configured to manage read requests and write requests for the back-end storage device. The logic is also configured to set the secondary cache server to a by-pass mode for read requests directed to any portions of the back-end storage device managed by the primary cache server prior to the failure. Moreover, the logic is configured to read an index of cache block descriptors (CBDs) managed by the primary cache server prior to the failure into a memory of the secondary cache server.
