Problems solved by technology

[0005] The purpose of the present invention is to provide a method that can solve the problem that the IP address drift cannot be performed automatically when the cluster NAS based on the Infiniband network uses the RDMA of the IB card as the service channel, which can greatly improve the performance of the cluster NAS using the RDMA of the IB card. It can ensure the high availability of the clustered NAS, and can automatically switch the service port according to the IP address in case of failure

Abstract

The invention discloses an IP address drift processing method, apparatus and system in an Infiniband network, a storage medium and a device. The method comprises steps of: receiving an RDMA connectionrequest command from the Infiniband network, and an IP address drift command; extracting an IP address preparing for IP address drift from IP address drift parameters; setting a mark indicating thatany new IO request in a network is no longer received; processing all IO requests cached on an IP address connection; and disconnecting the RDMA connection, and deleting the IP address. The method solves a problem that a logic link and a physical link are asynchronous after an IP address in the Infiniband network drifts.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to a method, device, system, storage medium and equipment for processing IP address drift in an Infiniband network. Background technique [0002] A Network Attached Storage (NAS) cluster is a combination of loosely coupled computing servers composed of multiple nodes, which cooperate to provide external services. Among them, IP address drifting is an essential function in high-availability cluster NAS. The cluster NAS with this function can quickly migrate the business on the faulty port to other available ports of the same type without interrupting the host business. , and the user is not aware of it. After the faulty port recovers, it can take over the previous business again. [0003] The Remote Direct Memory Access (RDMA) of the Infiniband network card (IB card) generally used in high-performance cluster NAS is used as a business channel. InfiniBand is a "conversion cable" tech...
