Embodiment Construction

[0035] see Figure 1 to Figure 3 As shown, the present invention will be described in detail below.

[0036] An efficient cache server based on distributed files, used to communicate with clients, including input processors, readers, cache listeners, output processors (such as figure 1 shown); where: the input processor is used to receive the client's read and write service requests, client authentication, client request types (including read requests and write requests), and to pass legal requests to the reader for processing.

[0037] The reader is used to verify the client request delivered by the input processor, read data output, and write data processing; the reader includes a read-only primary cache (RD1), a read-only secondary cache (RD2) and a write-only cache (WL); the read-only primary cache is used to record the physical or memory address bits of the file blocks in the file table; the read-only secondary cache is used to record that the write-only cache has not be...

Abstract

The invention provides an efficient caching server based on distributed files. The caching server is used for communicating with a client and comprises an inputting processor, a reader-writer, a caching listener and an outputting processor. The inputting processor is used for receiving reading and writing requests from the client, identification of the client and request types of the client, and transmitting legitimate requests to the reader-writer for processing. The reader-writer is used for verifying the requests of the client transmitted by the inputting processor, outputting read data and processing written data. The caching listener is used for listening business and system events. The outputting processor is used for sending data information read by the reader-writer or return states of the written data to the client. The caching server has the advantages that large file data storage is guaranteed while small data performance can be supported.

Description

technical field [0001] The invention relates to a high-efficiency caching server based on distributed files. Background technique [0002] According to the data of did you know (http: / / didyouknow.org / ), the amount of information currently accessible on the Internet is close to 1 zi = 1 trillion trillion. Different from the current common centralized storage technology, distributed storage technology does not store data on one or more specific nodes, but uses the disk space on each machine in the enterprise through the network, and distributes these The storage resources constitute a virtual storage device, and the data is scattered and stored in every corner of the enterprise. [0003] At present, the mainstream distributed storage technologies in the industry can be roughly divided into structured data, unstructured data, and semi-structured data. Regardless of any distributed storage method, its purpose is to disperse and store client data in different storage devices in...
