ABSTRACT:
A computer system or computer server system having redundant devices that are periodically checked in order to determine whether the redundant devices would be operational if the primary devices failed. The primary and redundant devices are in electrical communication with a controller circuit which, in turn, is responsive to a microprocessor and/or the computer's operating system. The primary and redundant devices can be hot-pluggable so that the computer system does not need to be powered down when and if the primary or redundant devices need to be replaced.
