Abstract
The present specification provides a distributed lock management message transmission method and device and a two-node server. The method comprises: establishing a connection with a cross-node in a two-node server by using a non-transparent bridge (NTB) virtual network card, the NTB virtual network card being a network card virtually formed by an NTB, and the connection being based on a PCIe channel; and transmitting a distributed lock manager (DLM) message to the cross-node by using the NTB virtual network card through the connection.
