Patent ID: 8560774

Claim:
A method, comprising: configuring, by a processor, a first interconnect card, wherein a first controller is included in the first interconnect card; configuring a second interconnect card coupled to the first interconnect card, wherein a second controller is included in the second interconnect card; in response to a failure of the first controller included in the first interconnect card, controlling the first interconnect card via the second controller included in the second interconnect card; and in response to a failure of the second controller included in the second interconnect card, controlling the second interconnect card via the first controller included in the first interconnect card, wherein the first controller is included in a daughter card, the method further comprising: in response to the failure of the first controller, replacing the daughter card, to replace the first controller with a third controller; in response to a failure of external power to the first interconnect card, using a capacitor and a battery to provide power to maintain the first interconnect card in an operational state; and in response to a failure of a replaceable solid state device included in the first controller, replacing the replaceable solid state device with a new solid state device while the first interconnect card is operational.
