Description
Technical field
The invention relates to a kind of network and store framework, refer to that especially data that network storing system and a kind of that a kind of data that can be used to promote a network store-service (Net Storage Service) write usefulness can be used to promote this network store-service write the network storage method of usefulness.
Background technology
The network storage server (network-attached storage is a kind of through network connections NAS), and through utilize that this file of Samba shares procotol carry out the storage facilities of file access so that computer system to be provided.Through a distributed framework; The network storage server can provide the network data shared mechanism of unlimited expansion capacity easily, as long as connect to network any node, the computer of various different operating systems; Just can pass through the network storage server; Enjoy conveniently file access service, therefore, the writing speed on the network storage server just becomes a very important problem.
Generally speaking, the data length that Ethernet (EtherNet) divides into groups is generally 1.5K hyte (wherein useful data can be the data length of 1～1460 hyte), and hard disk is to be the unit of data length with sector (sector); A sector approximately is 512 hytes; That is to say that the network storage server is different data formats through the data structure of the data that network terminal received with the data structure of the data that write to hard disk, therefore; In traditional technology; Can the data that received be recombinated in the operating system of network storing system, so that carry out the conversion of data format, for instance; Please refer to Fig. 1, Fig. 1 illustrated is a kind of simplification block schematic diagram of traditional network storing system 100.As shown in Figure 1; Document processing module 140, the first data buffer zones 110 that network storing system 100 includes one first data buffer zone 110, one second data buffer zone 120, one the 3rd data buffer zone 130 and an operating system are used for storing a storage data that is received through a network terminal, and this storage data includes the message box (for example DS1, DS2...) of a plurality of 1.5K hytes; Second data buffer zone 120 includes a plurality of memory pagings (Page0～Page14) for example; These a plurality of memory pagings are used for storing this storage data desire to write to a storage device 170 (a for example hard disk), as a user (network terminal machine 160 that for example Fig. 1 illustrated) in the time of will this storage data being write storage device 170, in the core layer (Kernel level) of operating system; This storage data (DS1, DS2...) can utilize ICP/IP protocol to be stored to first data buffer zone 110 through one first network terminal 150 from network terminal machine 160 earlier; Afterwards, in the application layer (Application level) of operating system, network storing system 100 can utilize an a processor (central processing unit (CPU) for example; For not being shown among the figure for purpose of brevity) this storage data copied to the 3rd data buffer zone 130 of network storing system 100; The 3rd data buffer zone 130 can temporary this storage data, by the time collected this storage data after, network storing system 100 is just recombinated this storage data; Afterwards; This processor can copy to this storage data in these a plurality of memory pagings of second data buffer zone 120, and then, network storing system 100 is handled the document processing module 140 that this storage data in the memory paging of second data buffer zone 120 sends operating system to; The document processing module 140 of operating system writes storage device 170 through one second network terminal 180 after handling again; Yet the document processing module 140 of operating system carries out the normal process of file process can use up long time, therefore; When using traditional network storing system 100; It is very poor that the data of network store-service (Net Storage Service) write usefulness, and for instance, the data of this network store-service write usefulness and have only 13MB/s.
Summary of the invention
In view of this; The data that one of the object of the invention is to provide network storing system that a kind of data that can be used to promote a network store-service (Net Storage Service) write usefulness and a kind of can be used to promote this network store-service write the network storage method of usefulness, to solve the above problems.
