Embodiment Construction

[0035] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0036] see figure 1 , the present invention proposes a method for accessing data, including:

[0037] Step 100, the NAS head receives the write request from the user, and forwards the write request to the SAN.

[0038] In this step, the write request includes data to be written.

[0039] Step 101, the SAN saves the data in the write request, and saves the correspondence between the data identifier and the data storage address of the data in the write request.

[0040] In this step, the data identifier may be a data type, a data number, and the like. Specif...

Abstract

The invention discloses a method for accessing data, a NAS head and a SAN. The corresponding relationship between the data identifier of the data in the write request and the data storage address. Through the solution of the present invention, the correspondence between the data identifier and the data storage address is saved by the SAN, so that after the NAS head has processed the write request, it can continue to process the next read request or write request without corresponding Synchronization of relationships, thus improving the processing speed of the NAS head.

Description

technical field [0001] The invention relates to computer storage technology, especially a method for accessing data, a NAS machine head and a SAN. Background technique [0002] With the rapid development of network applications and the climax of urban security development, the amount of information data is increasing, and the demand for fast access to massive data at the petabyte (PB, Petabyte) level is becoming more and more. [0003] Existing methods for accessing data broadly include: [0004] The additional storage (NAS, Network Attached Storage) head receives the write request from the user, and sends the data in the write request to the network storage (SAN, Storage Area Network) for storage; after the SAN storage is completed, the data in the write request The corresponding relationship between the data identifier and the data storage address is sent to the NAS head; the NAS head saves the received corresponding relationship, and sends the received corresponding rela...
