A method of recovering the state of a failed node in a distributed shared memory system, includes directing a flush of data from a failed node, and flushing the data from the failed node to a memory node. In the method, a first plurality of the addressable locations is allocated as in-use locations, and a second plurality of the addressable locations is allocated as spare locations. A plated metal layer including a plurality of exposed metal posts can project outwardly beyond the major surface of the dielectric element. The valve characteristic circuit is mounted on the valve housing, and includes a plurality of resistors.
