Document Type and Number:
WIPO Patent Application WO/2018/049899
Kind Code:
A1
Abstract:
Disclosed are a queue management method and apparatus. The method comprises: monitoring an occupancy rate of an NVMe queue of a Host end, wherein the NVMe queue comprises a submission queue (SQ) or a completion queue (CQ), the SQ is used for issuing an I/O request of the Host end to an NVMe SSD controller, and the CQ is used for feeding a response, with respect to the I/O request, of the NVMe SSD controller back to the Host end; and where the occupancy rate of the NVMe queue is greater than or equal to a pre-set upper-limit threshold value, increasing the number of NVMe queues, and processing I/O data of the Host end by means of the increased NVMe queues. By means of the present invention, the problem in the prior art that, in a server system with an NVMe protocol, the data processing performance of the server system decreases due to the fixed number of NVMe queues can be solved.
