Resource optimization method and device for a ceph system

Abstract

The invention discloses a resource optimization method and device for a CEPH system. The method includes: determining the OSD equipment number of each mainframe in the mainframe set of the CEPH system as the OSD resource score of the mainframe; calculating the RAM resource score of each mainframe according to the total capacity of the OSD equipment of each mainframe in the mainframe set and the total capacity of the RAM equipment of each mainframe; calculating the mainframe resource score of each mainframe according to the corresponding OSD resource score and the RAM resource score; determining that the MON service allocation priority of the mainframes is higher when the mainframe resource scores are higher, and deploying the MON service according the priority of each mainframe. By the resource optimization method, an administrator only needs to pay attention to the deployment of the OSD equipment, the optimal MON service deploying scheme can be obtained according to the deployment of the OSD equipment, unreasonable deployment, caused by the subjective factors of the administrator, of the MON service can be avoided to a certain degree, and the deployment reasonability of the CEPH system is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of distributed storage systems, and more specifically, to a resource optimization method and device for a CEPH system. Background technique [0002] CEPH is committed to providing a highly scalable, highly reliable, and high-performance distributed storage system. The underlying implementation of CEPH is Rados (Reliable Autonomic Distributed Object Storage). Rados is the cornerstone of CEPH, including OSD (object storage device) devices, Important components such as MON (monitor) service. Among them, the OSD device provides storage resources, which can be a Disk, partition, etc., and the MON service maintains the global state of the entire CEPH system, including various MAP information. [0003] For the deployment of the CEPH system, the official CEPH Deploy tool is usually used. Specifically, the administrator uses the pre-planned MON service and OSD device information to deploy the MON service an...

Problems solved by technology

However, since the deployment planning of MON services and OSD devices is implemented by the administrator, it may not be possible to ensure that each deployment is reasonable due to various subjective factors of the administrator.

Unreasonable deployment will reduce the stability of the system, and will also cause waste of resources and increase maintenance costs in the later period, especially will have an unpredictable impact on the running business
