Modular and Redundant Data-Storage Controller And a Method for Providing a Hot-Swappable and Field-Serviceable Data-Storage Controller

摘要

A modular and redundant storage controller system includes management modules, controller modules and an interconnect module. The management modules provide direct-current power and signals to respective controller modules. The controller modules include respective signal interfaces, direct-current interfaces, and interconnect interfaces. The signal interfaces couple the controllers to a respective management module. The direct-current interfaces couple the controllers to a respective management module. The interconnect module includes a pair of connectors arranged to couple a pair of the controller modules via the respective interconnect module interfaces.
