Abstract

The invention discloses an IO request forwarding method between storage controllers, which is applied to a main storage controller and comprises the following steps of: receiving each IO request sent by a host end; selecting a slave storage controller from the slave controller cluster; reading an upper limit value of the number of processable IO requests corresponding to the slave storage controller; and forwarding each IO request to the slave storage controller according to the IO request number upper limit value. By applying the IO request forwarding method between the storage controllers provided by the invention, the load of the slave storage controllers is prevented from being too large, the IO request forwarding efficiency is improved, and the data security is improved. The invention further discloses an IO request forwarding device and equipment between the storage controllers and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the field of storage technologies, in particular to a method, device, device and computer-readable storage medium for forwarding IO requests between storage controllers. Background technique [0002] In common storage controllers, in order to achieve redundant backup of data, two storage controllers, the primary storage controller and the secondary storage controller, are usually set up, and the IO requests received by the primary storage controller are forwarded to the secondary storage controller. IO requests are processed by both the primary storage controller and the secondary storage controller. [0003] However, as the number of IO requests increases, the forwarding efficiency of IO requests will decrease, and the storage controller will be overloaded, causing network congestion. Safety. [0004] To sum up, how to effectively solve the problems of low IO request forwarding efficiency, network congestion, and thr...
