Embodiment Construction

[0021] Such as figure 1 As shown, the data storage server of the present invention is referred to as DS for short, and the metadata server is referred to as MS for short. After identifying the MS, actively join the network storage cluster.

[0022] The present invention uses the Iinux2.6.38.2 kernel as the deployment platform of the shared storage system. By customizing the characteristics of the operating system kernel and applying virtualization patches, the system supports network connectivity of virtual machines, I / O storage, and distributed storage.

[0023] The present invention adopts the linux network distributed transmission algorithm, based on the open-source characteristics of the linux operating system, and encapsulates the communication modules between the nodes of the network storage in the form of a drive, so as to adapt to the drive of distributed storage, and named it gcloud-dnet.ko to replace The original system drives Inet to support virtualization applicat...

Abstract

The invention relates to the field of cloud calculation, in particular to a shared storage method suitable for migration and fault tolerance of a virtual machine. According to the invention, a data storage server and a metadata server are respectively loaded with a network driving module; the metadata server actively searches each data storage server on the network through a fixed multicast group method; and each data storage server actively adds into a network storage cluster after identifying the metadata server through key words information. By adopting the method, the failure and transmission problems of an integrated storage system can be effectively solved; and the method can be widely used for storage of migration and fault tolerance of the virtual machine.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a shared storage method suitable for virtual machine migration and fault tolerance. Background technique [0002] Cloud computing (Cloud Computing) is a new term born in 2007, and there is still no generally accepted definition. Cloud computing is a business computing model, which distributes computing tasks on a resource pool composed of a large number of computers, enabling users to obtain computing power, storage space and information services on demand. The cloud computing operating system is the overall management and operation system of the cloud computing backstage. Cloud platform integrated management system on the platform. [0003] Distributed File System (Distributed File System) means that the physical storage resources managed by the file system are not necessarily directly connected to the local node, but are connected to the node through a computer network. The de...
