Server cluster unit system with single system image

Abstract

The invention discloses a server group system with single system reflection, including a hardware layer, a distributed virtual machine monitor layer and an operation system layer; wherein, the hardware layer includes a plurality of nodes, a CUP of the nodes supports the hardware virtualization and the nodes are connected via a high-speed network. The distributed virtual machine monitor layer is provided with a virtual machine monitor on the hardware of each node and the virtual machine monitors of the nodes are communicated through bottom communication software and the high-speed network. The operation system layer supports various commercial operation systems of cc-NUMA and existing various cc-NUMA-oriented paralleling software can be operated on the system without modification. Based on the virtualization of the hardware resources, the system achieves the single system reflection of the server group system. The server group system provided by the invention has the advantages of good transparency, high performance, wide application range, moderate realizing difficulty, etc.

Description

technical field [0001] The invention relates to a server group system with a single system image, in particular to a server group system using a virtualization technology to realize a single system image. Background technique [0002] Virtualization is a broad term generally used in computing to refer to computing and processing that runs on a virtual basis rather than a real one. Virtualization technology refers to the technology of abstracting physical resources. Virtualization technology can build a virtual platform between the hardware and the operating system, and realize the construction of multiple isolated operating domains on the same hardware platform. Each operating domain can run its own operating system and application software. [0003] Virtualization technology originated in the 1960s. IBM first used virtualization technology to implement virtual machines in the System / 360 computer system. With the successful promotion of System / 370 and other series machines,...
