Solid state disk access method and storage equipment

Abstract

The embodiment of the invention provides a method for accessing a solid state disk and storage equipment, the storage equipment comprises a network card, a memory and the solid state disk, in the method, the network card receives to-be-written data and a write command, the write command is used for instructing to write the to-be-written data into the solid state disk, and after the to-be-written data and the write command are received, the network card writes the to-be-written data into a memory and writes the writing command into a submission queue of the solid state disk, and then the network card informs the solid state disk of the to-be-executed command in the submission queue of the solid state disk and writes the command when the to-be-executed command is executed. And the solid state disk acquires the to-be-written data from the memory according to the writing command, and writes the to-be-written data into a medium of the solid state disk. According to the method, the time delay of data access can be greatly reduced, and meanwhile, the CPU occupancy rate of the storage equipment can be greatly reduced.

Description

technical field [0001] The embodiment of the present application relates to the computer field, and in particular to a method for accessing a solid-state hard disk and a storage device. Background technique [0002] A current storage system may adopt forms such as distributed storage, network-attached storage (network-attached storage, NAS), storage area network (storage area network, SAN), and the like. In these storage systems, clients and storage devices are connected through networks. Among them, a solid state disk (solid state disk, SSD) is applied to the above-mentioned various storage systems due to its advantages of high bandwidth, low latency, and high throughput. For the storage system, how the client efficiently accesses the data in the solid-state disk through the network is an important issue. [0003] In the prior art, when the client needs to access the solid-state disk of the storage device, the central processing unit (central processing unit, CPU) of the ...
