Problems solved by technology

The select mechanism adopts a polling strategy, that is, it needs to traverse the entire monitored descriptor set, which makes its work efficiency inversely proportional to the number of monitored events; and the number of events monitored by select is obviously limited
Due to the above shortcomings, the mechanism of select monitoring cannot achieve high-performance concurrent services

Abstract

The invention provides an IPSAN-based socket communication method and device and storage equipment. The method comprises the steps that a socket for monitoring client requests is created and added into epoll, and a callback function is registered; the client requests are received, and a new connection file descriptor is added into epoll; when the file descriptor is readable, the callback function is called to analyze IPSAN requests, and an interface at the storage end is called to carry out io operation; a modification event corresponding to the writable file descriptor for which operation is finished is sent to a client side. By using the epoll technology, the event corresponding to the new connection file descriptor can be directly returned, a polling strategy is not adopted, the phenomenon that the efficiency is remarkably lowered along with increasing of the number of monitoring events is avoided, the problem that system exception is caused by limiting on the number of events can be solved, and the storage end concurrent volume is greatly improved.

Description

technical field [0001] The invention relates to the field of network storage, in particular to an IPSAN-based socket communication method, device and storage device. [0002] technical background [0003] With the development of science and technology in modern society, computers have been widely used in various fields. In today's digitization, networking and informationization, computer network technology has been developed rapidly and widely used. The storage system based on IPSAN can realize the SAN storage function with only a small investment, and even directly utilize the existing TCP / IP network. Compared with the previous network storage technology, it solves the problems of openness, capacity, transmission speed, compatibility, security, etc., and its superior performance has attracted much attention and favor. The IPSAN realizes the data transmission between the client and the storage end through SOCKET communication. [0004] In TCP / TP network applications, the ma...
