“The “heartbeat” technology enables them to be connected through 100M network cards and 100M network cables; the cables use jumpers, such that pins 1, 2, 3, and 6 on the host side correspond to pins 3, 6, 1, and 2 respectively on the secondary device side. The two machines communicate with each other in a point-to-point manner using the TCP/IP protocol, and they monitor one another through heartbeat technology. Heartbeat information technology: As the name suggests, it works similar to detecting a person’s heartbeat – by periodically checking whether a global variable has changed; if no change occurs within a specified time frame, it is determined that the corresponding entity is ‘dead’.
