Embodiment Construction

[0014] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] The design idea of ​​the present invention is: in order to meet the needs of the dual-unit server to provide external network sharing services with strong real-time performance and high availability, a dual-ring network topology is used to connect the network links of the whole machine, and the four ports of the two switches are separately connected in a static aggregation manner. Converge in pairs to increase the bandwidth and protection function of the backbone network; in the redundant protection of the entire network topology, the DT-Ring protocol is used to realize the redundant protection function of the entire network, and the ring network is pruned into a ring-free tree Type network, to avoid the proliferation and infinite loop of packets in the loop network. The DT-Ring protocol implements fast detection of the LIKE status of th...

Abstract

The invention relates to a dual-unit server redundant network system. The main technical characteristics are that the d dual-unit server redundant network system comprises two unit servers and a network storage unit; each unit server comprises two server blades, a server disk controller, a timing system signal receiving module, a network switching module and a local storage array; the server diskcontroller is connected with the local storage array and the network switching module, the two server blades are connected with each other and are connected with the network switching module, and theclock signal receiving module is connected with one server blade; the two unit servers are connected through a network switching module and are connected to an external local area network; and the network storage unit is respectively connected to the network switching module of each unit server. The dual-unit server redundant network system is reasonable in design, high-performance and high-reliability database, file, transmission and other application and information service functions are provided for the outside by the ship-borne numerical value center cabinet, and the dual-unit server redundant network system has the advantages of being high in real-time performance, high in stability, high in link switching speed and the like.

Description

technical field [0001] The invention relates to the technical field of network interconnection, in particular to a dual-unit server redundant network system. Background technique [0002] As the core of the entire ship communication system, the shipboard numerical center puts forward high requirements for data processing capability, data transmission reliability and speed, and data storage security. The existing dual-machine hot backup system can meet the above requirements to a certain extent, that is, the central server is installed as two servers for mutual backup, and only one server is running at the same time. When it fails to start, another backup server will automatically start and run (usually about 2 minutes), so as to realize the normal operation of the entire network system. This dual-computer hot backup system is difficult to meet the above-mentioned requirements of the shipboard numerical center. Contents of the invention [0003] The purpose of the present...
