Abstract:
A first server of a storage controller is configured to communicate with a host via a first bus interface, and a second server of the storage controller is configured to communicate with the host via a second bus interface. Data is written from the host via the first bus interface to a cache of the first server and via the second bus interface to a non-volatile storage of the second server. The data stored in the cache of the first server is periodically compared to the data stored in the non-volatile storage of the second server.
