A data processing method and device for solid-state hard disk dual-port

Abstract

The embodiment of the present application discloses a data processing method and device for dual-port solid-state hard disks. The first message received by the target receiving queue is obtained. If the target receiving queue is determined to be the first type of receiving queue according to the target queue number, the target queue is judged Whether the sequence number is equal to the target port sequence number, if it is, it means that the first message sent by the port corresponding to the target port sequence number is processed, and it is necessary to judge whether the resources in the data management module meet the preset conditions. If not, it means that the resources in the data management module are insufficient, then Keep the value of the target port serial number unchanged, shield the target receiving queue, and re-execute the preceding steps for the next target receiving queue. It can be seen that in the case of insufficient resources, this scheme does not process the first message, and does not process the first message until the resources are sufficient, so as to avoid the problem of resource contention between the two ports in the case of insufficient resources, which is reasonable for the two ports Allocate resources to ensure that the performance of the two ports is consistent.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a data processing method and device for dual-port solid state disks. Background technique [0002] With the rapid development of Solid State Disk (SSD) technology, the application of dual-port technology in enterprise-level storage systems has become inevitable. Due to its advantages in high reliability, it naturally has more Broad prospects and markets. [0003] The dual ports can serve the same host or different hosts. The host can access the SSD in parallel through the dual ports. CPU) generally processes messages from dual ports in the order they are received. [0004] However, this data processing method will cause resource contention between the two ports, especially in the case of insufficient resources. Resource contention makes the CPU of the SSD only process messages from a certain port for a period of time. Only messages from the other port are processed for...

Problems solved by technology

[0004] However, this data processing method will cause resource contention between the two ports, especially in the case of insufficient resources. Resource contention makes the CPU of the SSD only process messages from a certain port for a period of time. Only messages from another port are processed for a period of time, and resource allocation is uneven, which leads to performance jitter of the two ports
