Split-brain Detector PartitionThe SBD Partition is a small space (usually 15MB or less) on a SAN where each node writes a packet to let others know it's "alive." If a node does not write its "I'm alive" packet within a configurable time, known as the heartbeat, then the node with the Master IP address will ping that node. If the node does not respond, the Master IP address node will send the "failed node" a "poison pill" packet, which tells the failed node to ABEND.
