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...

Embodiment Construction

[0014] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] In addition, the steps shown in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and, although a logical order is shown in the flow diagrams, in some cases, the sequence may be different. The steps shown or described are performed in the order herein.

[0016] Before introducing the present invention, two concepts of the prior art used in the present invention are first explained. They are:

[0017] 1) KVM virtual machine (kernel-based Virtual Machine), is an open source server virtualization module, which...
