Identification (ID) application method, device and system

Abstract

The invention provides an identification (ID) application method, device and system. The method comprises the following steps: host machine equipment sends fiber login (FLOGI) carrying a batch processing capacity request to a switch, so that the switch responds a batch processing capacity request carried in the FLOGI and then returns link state (LS)_ACC carrying batch processing configuration information to the host machine equipment; and after the host machine equipment receives the LS_ACC returned by the switch, if the switch is acquired to support batch processing operation in accordance with the batch processing configuration information, an FBATCH Request carrying the number of IDs to be applied is sent to the switch, so that the switch answers to the FBATCH Request if the switch detects to acquire that the number of allocable ID resources is not less than that of the IDs to be applied, and a FBATCH reply carrying the IDs of which the number is equal to that of the IDs to be applied is returned to the host machine equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an ID application method, device and system. Background technique [0002] With the continuous development of network storage and various distributed applications, enterprises and users have higher and higher demands on high-speed communication technology. FC (Fibre Channel, Fiber Channel) is a high-speed, high-reliability, low-latency, high-throughput data transmission system, which greatly meets the high-speed communication needs of enterprises and users, and can be widely used in high-performance storage , Large-scale database and data warehouse, storage backup and recovery, cluster system, network storage system, digital video network and other fields. [0003] In the FC network, the most important addressing method is to use 24bit FC ID (similar to the IP address in the IP network), and all host devices must obtain at least one FC ID to initiate external comm...

AI Technical Summary

Problems solved by technology

In the implementation application, there have been host devices that can virtualize up to 1K NPV ports, so if all 1k virtual NPV ports need to apply for FC ID, then you will see that there are a total of 1K times between the host device and the FC switch. Interaction process, which will greatly affect the working efficiency of FC, so that the time required for FC to switch from a failure state to a working state (for example, when an FC interface occurs link down and then link up, or hot plug and other events) will be greatly increased
