  • Storage controller having additional cache memory and a means for recovering from failure and reconfiguring a control unit thereof in response thereto
    Patent number: 5437022
    Abstract: A storage controller having additional cache memory and a system for recovering from failure and reconfiguring a control unit thereof in response thereto. The inventive controller includes a first cluster for directing data from a host computer to a storage device and a second cluster for directing data from a host computer to a storage device. A first cache memory is connected to the first cluster and a second cache memory is connected to the second cluster. A first nonvolatile memory is connected to the second cluster and a second nonvolatile memory is connected to the first cluster. Data is directed to the first cache and backed up to the first nonvolatile memory. The second cache is similarly backed up by the second nonvolatile memory. In the event of failure of the first cache memory, data is directed to the second cache and backed up in the second nonvolatile memory.
