A data storage subsystem in a distributed storage system having a plurality of predictive failure analyzing data storage devices. The subsystem furthermore has a circuit that is responsive to a predicted failure indication by a data storage device in relation to predetermined rules stored in memory for deterministically initiating a preventive recovery either by a data recovery procedure in the data storage device or by a fault tolerance storage arrangement in the subsystem.

Deterministic preventive recovery from a predicted failure in a distributed storage system

A disc storage subsystem includes a housing, at least one disc drive assembly received in a front portion of the housing, first and second controllers, and an intermediate electronic component. The disc drive assembly includes a carrier supporting a disc drive having an Advanced Technology Architecture (ATA) data interface. The first and second controllers each include a data port corresponding to the disc drive. The intermediate electronic includes multiplexing electronics having first and second data communication paths. The first data communication path provides electronic communication between the data port of the first controller and the data interface of the disc drive. The second data communication path provides electronic communication between the data port of the second controller and the data interface of the disc drive. The multiplexing electronics selectively opens and closes the first and second data communication paths in response to at least one control signal.
