A virtual server system and its data reading and writing method

Abstract

The invention discloses a virtual server system and a data reading-writing method thereof. The virtual server system comprises a virtualization server and a Glusterfs server terminal, the virtualization server comprises a Glusterfs client terminal module, a virtual log generating module is additionally arranged on the Glusterfs client terminal module, and the virtual log generating module is configured with a corresponding virtual log cache region. According to the virtual server system, the virtual log generating module receives random reading / writing requests of a virtual machine, the virtual log generating module records the writing requests into the virtual log cache region in a sequential mode, and meanwhile a backstage supporter periodically synchronizes the data of the virtual log cache region to the Glusterfs server terminal. According to the virtual server system and the data reading-writing method of the virtual server system, the reading and writing performance of discs of the virtual machine can be greatly improved on the basis that original hardware equipment is not modified, delay is reduced, and therefore the user experience of desktop virtualization can be effectively improved.

Description

technical field [0001] The invention relates to a computer data storage technology, in particular to a virtual server system capable of applying a KVM virtual machine and a data reading and writing method thereof. Background technique [0002] In recent years, with the rapid development of IT technology, virtualization technology has become increasingly mature. Virtualization technology abstracts physical resources into logical resources, such as CPU, memory, disk, input and output and other hardware devices into a "resource pool" that can be dynamically managed, greatly improving the utilization of hardware resources and allowing IT to respond to business changes. Be more resilient. Because virtualization can greatly reduce the overall cost of the data center, simplify server management, realize rapid server deployment and improve data center reliability, more and more organizations have begun to deploy virtualization platforms. The virtualization of the data center mainl...

Problems solved by technology

For traditional hard disks such as SATA or SCSI, because their random read and write performance is much worse than sequential read and write performance, it will affect the data storage efficiency of the entire system

[0003] At present, in the prior art, there is also a technical solution that uses the Glusterfs distributed file system to integrate disk resources on virtualized servers and disperse the disk input and output of each virtualized server. Input and output problems
