Abstract

The invention provides a distributed cluster file system. The system comprises physical servers and a storage server. Each physical server is provided with a distributed cluster management unit, a cluster logical volume management unit and a virtual case file system (VCFS) unit, wherein the distributed cluster management unit is used for providing heartbeat messages between the physical servers to ensure that all the physical servers in a cluster run normally; the cluster logical volume management unit is used for managing physical volumes, a logical volume group and logical volumes in the cluster; and the VCFS unit is used for storing the disk file data of virtual machines. The storage server is used for providing block-level storage equipment. According to the distributed cluster file system, a global namespace is adopted, file-level data is shared between system platforms, and storage equipment is added, so that the storage capacity, input / output (IO) bandwidth and load capacity of the system can be expanded on line, and the capacity can be reduced on line; and a storage system is prevented from a single-point failure, and can be ensured to run integrally continuously, and storage performance is improved.

Description

technical field [0001] The invention relates to the technical field of virtualization, in particular to a distributed cluster file system. Background technique [0002] Server virtualization, desktop virtualization and application virtualization are the three major virtualization technologies in computer virtualization. It is also an important technology for future cloud computing. At present, in various industries around the world, the promotion of virtualization technology has begun, and it is gradually becoming popular in the IT industry. [0003] Server virtualization and cloud computing technologies have become mainstream technologies in today's IT industry. And cloud computing has continuously improved requirements for various aspects, such as CPU calling mechanism, memory management mechanism, file calling mechanism, etc. However, with the continuous development of virtualization technology and cloud computing technology, the requirements for data storage are also ...
