Problems solved by technology

[0004] However, with the continuous increase of customer capacity requirements, the number of data processing requests that need to be executed simultaneously in the storage controller is increasing. However, the computing power of the processor in the storage controller is limited, which limits the storage controller that can simultaneously The number of executed data processing requests reduces the speed at which the storage controller executes data processing requests and increases the latency for the storage controller to execute data requests

Embodiment Construction

[0044] The technical solution in this application will be described below with reference to the accompanying drawings.

[0045] figure 1 is a schematic diagram of a storage system based on an all-flash array. As shown in the figure, the storage system includes at least one host 110 , at least one storage controller 120 , a switch 130 and at least one JBOF 140 . Each of the at least one host can be connected to at least one storage controller, and the at least one storage controller can communicate with any JBOF in the at least one JBOF through a switch. For example, the storage controller can control the storage space of the JBOF Access, or process the data in the storage space of JBOF.

[0046] Host (Host): You can apply for any one of the above at least one JBOF as a target (Target), that is, the host can access the above target by sending a data processing request to read data from the above target, or Write the data into the storage space of the destination.

Abstract

The invention provides a method and device for transmitting a data processing request, and the method comprises the steps that a solid state disk cluster JBOF obtains the data processing request transmitted by a storage controller, and the data processing request is used for accessing a target solid state disk SSD in the JBOF; the JBOF determines the type of the data processing request, wherein the type of the data processing request comprises a straight-through type and a background computing type; if the type of the data processing request is a straight-through type, the JBOF directly forwards the data processing request to the target SSD; and if the type of the data processing request is a background computing type, the JBOF sends the data processing request to a computing unit in the JBOF, and sends the data processing request processed by the computing unit to the target SSD. The speed of executing the data processing request by the straight-through type storage controller is improved, and the time delay of executing the straight-through type data processing request by the storage controller is reduced.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to methods and apparatus for transmitting data processing requests. Background technique [0002] Currently, an all flash array (All Flash Array, AFA) is generally composed of a storage controller (Storage Controller) and a solid state drive (solid state drive, SSD) disk set (Just Bunch of Flash SSD, JBOF), wherein the storage controller is used to execute A data processing request sent by a host (Host), the data processing request may include an IO request, an erasure code (Erasure Code, EC) request, a garbage collection (Garbage Collecting, GC) request, and the like. The storage controller can process the data to be processed according to the data processing request, and store the processed data in the JBOF, or send the data read from the JBOF to the host as processed data. [0003] The number of read and write operations per second (Input / Output Operations Per Se...
