Problems solved by technology

[0013] The disadvantages of the above PVFS scheme are: PVFS can only support LINUX system at present, the node fault tolerance is poor, and it is highly dependent on MGR
In addition, PVFS needs to install the corresponding Client software on the computing server, which is not suitable for the file system of the parallel storage server.

Embodiment Construction

[0043] The present invention provides a multi-machine file storage system and method. The core of the present invention is: multiple server nodes connected and communicated through high-speed Ethernet are used, and each server node saves and reads files through software segments.

[0044] Describe the present invention in detail below in conjunction with accompanying drawing, the structure of the embodiment of multi-machine file storage system described in this method is as follows figure 1 shown. The multi-machine file storage system includes N+1 (at least three) server nodes, all server nodes are equal in status, each server node is connected by high-speed Ethernet, and data communication and fault detection are performed through the high-speed Ethernet.

[0045] Each server node includes multiple IDEs (storage units) and NCs (network cards), using dual network backup, using some of the network cards for internal communication between server nodes, and using other part of th...

Abstract

The present invention provides a multi-machine file storage system and method, the system mainly includes a plurality of server nodes, each server node is connected by high-speed Ethernet, communicates through high-speed Ethernet, and each server node performs file storage in sections save and read. The method mainly includes: reading a corresponding data block from a file to be saved, and storing the read data block in segments in each server node in the multi-machine file storage system. With the invention, a low-cost, high-availability and high-performance multi-machine file storage scheme can be realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a multi-machine file storage system and method. Background technique [0002] A virtual storage system is an integrated system (storage pool) composed of multiple physical storage subsystems and logically managed by virtual storage software. The virtual storage system has more comprehensive service functions that the storage subsystems that make up the storage pool do not have. Virtual storage system is the practical application of virtual storage technology. [0003] The application of virtual storage technology has injected new impetus into the construction of IT systems, and virtual storage management software and management platforms occupy a key position in the entire IT system. Due to the relatively short development history of virtual storage technology and its products, the reliability and availability of virtual storage technology still need to be further improved in order to ...
