Abstract: A power line connector apparatus and a method of coupling a first power line connector to a second power line connector are provided. Embodiments include a first power line connector comprising an outer casing that includes a groove that forms a recessed space annularly around the outer casing, the groove opening radially outward from the outer casing; a second power line connector comprising an electrical contact housing including a rib that forms a recessed space annularly along the inner walls of the electrical contact housing; and a resilient retaining ring located at least partially within the recessed space of the groove, the ring compressing against the inner walls of the electrical contact housing as the first connector is inserted into the electrical contact housing of the second connector, the ring uncompressing within the recessed space of the rib as the first connector is fully inserted into the housing.

Abstract: In response to determining that a computing device to which one or more storage volumes within a storage-area network (SAN) have been assigned has satisfied a shutdown criterion, the storage volumes within the SAN are unassigned from the computing device. The storage volumes within the SAN are assigned to a cold-spare computing device, and the cold-spare computing device is booted from one of these storage volumes. Such computing device failover can be provided even where the computing devices are not clustered and even without employing virtualization.
