Abstract
The invention aims to provide new a novel file system structure and a network access way, which can effectively solve the problems of excess NAS (Network Attached Storage) nodes, inconvenient management and use, and the like in the prior art. The invention relates to an NAS virtual file system based on a storage device, comprising NAS equipment and an NAS file system, wherein a filter is arranged in the NAS file system. The realization method of the NAS virtual file system comprises two processes of writing operation and reading operation. The new novel file system and the network access way can organize a plurality of NAS equipment to realize the virtualization of the plurality of NAS equipment, so that a user looks like becoming a set of NAS equipment, realize the NAS virtualization based on the storage device is realized, not only save the hard disk space is saved, but also efficiently lowers the cost is e.fficiently lowered.
Description
Technical field
The present invention relates to a kind of virtual memory, particularly a kind of NAS Virtual File System based on memory device.
Background technology
NAS (Network Attached Storage, network attached storage) is that a kind of utilization has the server of big capacity hard disk or work station is realized information stores and resource-sharing by network technology.
The network storage is the most valued memory technology in the current field of storage, and NAS equipment is used widely in every field with good sharing, good control of authority ability and cross-platform ability.But, to explode period at current information, the dilatation of memory device is inevitable.In the time of NAS storage dilatation, need buy the NAS node again, the deuce to pay that a plurality of NAS nodes cause management to a great extent and use.
Summary of the invention
The purpose of this invention is to provide a kind of the present invention and define new file system structure and access to netwoks mode, the NAS node that can effectively solve prior art is too many, problems such as management and use inconvenience.The present invention relates to a kind of NAS Virtual File System, comprise NAS equipment and NAS file system, in the NAS file system, be provided with filter based on memory device.
The number of described NAS equipment is three.
Based on the NAS Virtual File System of memory device, its implementation comprises write operation and two processes of read operation.
Its write operation comprises the steps:
When 1) any one user in the network carries out write operation, the write operation instruction is sent in the network;
2) by group ripple or switch ports themselves mirror image, three NAS equipment receive write order simultaneously;
3) three NAS equipment are by the token mode, and decision is to the response mode of write operation;
When 4) token had equipment and receives the written document order, whether all NAS equipment sent messages inquiry files and exist in network, if exist in other equipment, notify this device responds write request, if file does not exist, token device is created this document, and the response write request.
Its read operation comprises the steps:
When 1) any one user in the network sends the read operation request, read operation is sent in the network, all NAS equipment are all received this request;
2) if there is the file of request in certain equipment in the network, this NAS device responds read request then, otherwise do not do any response;
3) if all NAS equipment do not respond read request, through certain hour, the token owner finds there is not device responds, then returns and reads the file failure, notice read request main frame.
The invention has the advantages that: the present invention is a kind of new file system and access to netwoks mode, a plurality of NAS equipment can be organized, realize the virtual of a plurality of NAS equipment, make the user seem to become a cover NAS equipment, realization is virtual based on the NAS of memory device, both saved hard drive space, effectively reduced cost again.

Embodiment
The present invention relates to a kind of NAS Virtual File System, comprise NAS equipment and NAS file system, in the NAS file system, be provided with filter,, merge into a single file tree the file forest that a plurality of file system are formed based on memory device.This file tree is made of jointly a plurality of memory devices, and each NAS storage is a record part wherein only, the reasonable utilization and the concurrent access of implementation space.
The number of described NAS equipment is three, is provided with the multilayer catalogue in the NAS equipment, can be with various files under the catalogue.In native system, our utilization group ripple or switch ports themselves mirror image mode, the each read-write requests of user all sends on three NAS equipment simultaneously, and every equipment responds according to actual conditions.
The NAS Virtual File System based on memory device among the present invention, its implementation comprise write operation and two processes of read operation.
Its write operation comprises the steps:
When 1) any one user in the network carries out write operation, the write operation instruction is sent in the network;
2) by group ripple or switch ports themselves mirror image, three NAS equipment receive write order simultaneously;
3) three NAS equipment are by the token mode, and decision is to the response mode of write operation;
In system start-up, token produces (can obtain token according to the first time of IP address minimum) immediately; In use, can transmit token according to two kinds of principles: the idle the maximum of minimum acquisition token of memory space utilization rate or memory space obtains token.
When 4) token had equipment and receives the written document order, whether all NAS equipment sent messages inquiry files and exist in network, if exist in other equipment, notify this device responds write request, if file does not exist, token device is created this document, and the response write request.
Its read operation comprises the steps:
When 1) any one user in the network sends the read operation request, read operation is sent in the network, all NAS equipment are all received this request;
2) if there is the file of request in certain equipment in the network, this NAS device responds read request then, otherwise do not do any response;
3) if all NAS equipment do not respond read request, through certain hour, the token owner finds there is not device responds, then returns and reads the file failure, notice read request main frame.
Claims (5)
