Embodiment Construction

[0057] The method of the present invention can allocate the logged-in storage controllers for the client according to the load conditions of the storage controllers of each server in the cluster system, and can solve the problem of using the static balanced scheduling method to evenly distribute the ISCSI targets for the cluster nodes in the prior art. There is a large difference in the load size of the system, and the waste of system resources is high.

[0058] see figure 2 , the present invention realizes the method for load balancing comprising:

[0059] Step S201: the client sends a login request to the main storage controller;

[0060] Step S202: The primary storage controller uses the load conditions of each storage controller to select a storage controller with the smallest load for the client to log in.

[0061] Step S203: the client logs in to the aforementioned storage controller.

[0062] The method of the present invention will be described in detail below with...

Abstract

The method includes steps: client end sends out request of ISCSI registration; using loading condition of each memory controller, main memory controller selects memory controller with minimal load for client end to carry out registration. Comparing information of load of each memory controller queried from load despatcher, the selects memory controller with minimal load for client end to carry out registration so as to balance load of each memory controller in group system.

Description

technical field [0001] The invention relates to the technical field of computer clusters, in particular to a method, system and storage controller for realizing load balancing in a cluster system. Background technique [0002] A cluster is a group of computers that, as a whole, provides users with a set of network resources. These individual computer systems are the nodes of the cluster. An ideal cluster is that users are never aware of the underlying nodes of the cluster system. In their view, the cluster is a system rather than multiple computer systems, and the administrator of the cluster system can add and delete nodes of the cluster system at will. [0003] The Internet Small Computer System Interface (ISCSI, Internet Small Computer System Interface) has been widely used in the cluster system at present. The ISCSI protocol is based on the Small Computer System Interface (SCSI, Small Computer System Interface) protocol and the Transmission Control Protocol / Internet Pr...
