Abstract

A method, apparatus and system for processing access information of a storage device. The method comprises: a processor of an access device determines a storage device identifier corresponding to a virtual address according to the virtual address comprised in an access request initiated by a process; generates an access request message, the access request message comprising an access address; and sends, according to the storage device identifier, the access request message to the processor of the storage device that the storage device identifier points to, so that the processor of the storage device executes, according to the access address comprised in the access request message, access request operation in a storage medium that the access address points to. The access performance of an integrated storage device is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer storage, and in particular, to a method, device, and system for processing access information to a storage device. Background technique [0002] In the prior art, there are mainly two methods for accessing the storage medium. The first method is to access the storage medium through the kernel. Figure 8 A system architecture diagram of a storage medium access method provided for the prior art, such as Figure 8 Shown: [0003] The core sends the virtual address to the memory management unit (MMU), and the MMU queries the translation lookaside buffer (TLB) table, and finds that the virtual address to be accessed has no physical address corresponding to it. The MMU sends a page fault interrupt to the core, and the core responds to the interrupt. After protecting the operating environment, it falls into the kernel, and the physical memory allocation program in the kernel (s...
