Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The invention provides a method for transitioning the state of a chassis port, such as figure 1 shown, including the following steps:

[0032] S101. According to the logic of the abstract D flip-flop, create the first variable representing the logic clock, the second variable representing the state of the chassis port queried in real time, the third variable representing the state of the chassis port of the logic output, and the state of saving the latc...

Abstract

The invention discloses a case port state conversion method, device and equipment and a storage medium. The method comprises the following steps: according to logic of an abstract D trigger, creatinga first variable representing a logic clock, a second variable representing a case port state inquired in real time, a third variable representing a case port state output by logic, and a fourth variable representing a storage latch state; identifying a current state of the storage device for carrying out case port state conversion; and according to the identification result, controlling the created variable value to determine whether to execute a case port state conversion operation or not. According to the method and the device, the case port state conversion is realized by utilizing the algorithm principle of the D trigger, so that the case port state conversion time can be shortened, the discovery frequency can be reduced, the unnecessary case port state conversion logic execution is reduced, the influence on the user service performance is reduced as much as possible, and the resource utilization rate of the storage equipment is improved.

Description

technical field [0001] The invention relates to the technical field of chassis management, in particular to a method, device, equipment and storage medium for transitioning the state of a chassis port. Background technique [0002] A storage area network (Storage Area Network, SAN) provides data transmission between computers and storage systems. A storage device refers to one or more disk devices used to store computer data, usually referring to a disk array. Each chassis in the storage device has two ports, and the status can be online, degraded, or offline. Any of the two ports A state transition that occurs will result in a transition of the chassis port state. [0003] At present, with the development of SAN network and big data, the demand for large-scale and high-capacity disk array systems is increasing. For high-end storage, generally more disk cabinets are required than for low-end and mid-range equipment. For a storage device with a relatively large number of d...
