A cloud host startup control method and system based on distributed storage clusters

Abstract

The invention discloses a cloud host start-up control method and system based on a distributed storage cluster. The method includes: introducing a fragmentation routing table at the client, and marking the fragmentation data that each cloud host needs to read during the start-up phase as available Accelerated read shards; migrate accelerated read shards from SATA Pool to SSD Pool; during the startup phase of the target cloud host, read the corresponding accelerated read shards from the SSD Pool to start the target cloud host. By introducing the fragment routing table, it breaks the limitation that the virtual disk fragments are only stored in one storage resource pool, identifies the fragment data read during the startup phase of the cloud host, and migrates these data to the high-performance SSD Pool , to avoid storing the entire system disk of the cloud host in the SSD Pool, reducing the waste of space, and at the same time meeting the read performance requirements when batch cloud hosts start, effectively improving the concurrent batch startup supported by the SSD Pool storage pool The number of cloud hosts.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a distributed storage cluster-based cloud host startup control method and system. Background technique [0002] Cloud host is an important part of cloud computing in infrastructure applications. The product originates from cloud computing platform, which integrates three core elements of Internet applications: computing, storage and network. Cloud hosts generally exist in the form of virtual machines. In the field of public cloud or private cloud, the distributed storage cluster system that connects servers through switches, integrates the disks on each server into a virtual storage pool, and provides storage services as a whole is the current mainstream solution. [0003] In the field of private cloud, due to cost constraints, the servers currently building private cloud distributed storage clusters are generally equipped with SATA disks with high capacity and l...

Problems solved by technology

[0005] In order to ensure the security of the system disk data, the SSD Pool storage resource pool needs to use multiple copies to save the fragmented data of the system disk. However, this causes a serious waste of space, which greatly limits the supported cloud Number of hosts to start in batches
