System and method for optimizing fault tolerant storage controllers
A system and method for optimizing fault tolerant storage controllers includes a fault tolerant hardware component comprised of an input interface, at least two output interfaces and, if necessary, a power source connection. The fault tolerant hardware component may be embedded in a storage controller or separately housed within an enclosure. The fault tolerant hardware component may couple with a host information handling system and with two or more storage controllers, which are connected to mass storage devices to form storage arrays. Multiple fault tolerant hardware components can be coupled with a single host information handling system when it includes multiple host ports. Further, the fault tolerant hardware component may be coupled with other fault tolerant hardware components.
