Embodiment Construction

[0050] The technical solutions in the embodiments of the present invention will be clearly described below in conjunction with 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.

[0051] An embodiment of the present invention provides a method for processing input and output IO requests, which is applied to a file system, wherein the structure of the file system 10 is as follows figure 1 As shown, including a virtual file system layer 101, a block IO layer 102, and a device driver layer 103, the file system 10 can also include a service level information base 104, and the service level information base 104 can include: the user's service level and the vi...

Abstract

An input/output (IO) request processing method and a file server, where the method includes adding, according to different service levels carried in IO requests of users, the IO requests of the users to corresponding cache queues for processing at a virtual file system layer, a block IO layer and a device driver layer separately, thereby meeting different service level requirements for the IO requests of the users.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to an input and output IO request processing method and a file server. Background technique [0002] The Linux system is a multi-user, multi-task, multi-thread and multi-central processing unit (Central Processing Unit, CPU) operating system. The file systems in the Linux system include different physical file systems. Since different physical file systems have different structures and processing methods, in the Linux system, different physical file systems can be processed through a virtual file system (Virtual File System, VFS). [0003] In the prior art, when a VFS receives a user's input and output (input output, IO) request, regardless of whether the service level of the user's IO request is the same, the same processing is performed by the VFS. Therefore, the user's IO request cannot be satisfied. Request different service level requirements. Contents of the invention ...
