Problems solved by technology

[0004] (1) The input and output (I/O) performance of the distributed file system is poor, because the distributed file system is generally implemented by a two-layer file system, and the two-layer file system includes a distributed file subsystem and a local file subsystem , therefore, there are more layer structures and non-I/O access operations on the data I/O path, resulting in poor I/O performance of the distributed file system;
[0005] (2) Although the FC-SAN storage technology has the characteristics of high scalability, etc., the FC-SAN storage technology is limited to the FC-SAN storage network and cannot effectively utilize the cheap and widespread IP network; moreover, the In the FC-SAN storage technology, the client must use a host bus adapter w

Example Embodiment

[0148] Example

[0149] Figure 7 A schematic diagram of a specific implementation flow of the implementation method of a cloud disk according to an embodiment of the present invention, as shown in Figure 7 As shown, the method includes:

[0150] Step 701: the user sends a file request message to the server through the client;

[0151] Step 702: According to the file request message, the server searches whether the file information corresponding to the file request message is stored in its own data buffer area; if it is stored, execute step 703; otherwise, execute step 704;

[0152] Step 703: the server sends the file information corresponding to the file request message to the client for the user to read;

[0153] Step 704: the server applies to the distributed lock server for a lock service corresponding to the file request message;

[0154] Step 705: the server generates a SCSI command corresponding to the file request message according to the lock service;

Abstract

The invention discloses a realization method for a cloud disk. The realization method comprises the following steps: receiving a file request message, and applying a lock service corresponding to the file request message according to the file request message; generating an SCSI commend corresponding to the file request message according to the lock service; receiving file information corresponding to the file request message, which is looked up according to the SCSI commend. The invention further discloses a cloud disk, a server, a cloud storage server, a cloud mapping server and a distributed lock server.

Description

technical field [0001] The invention relates to cloud computing technology, in particular to a cloud disk and its implementation method and device. Background technique [0002] Currently, the more popular cloud disks include Netease Cloud Disk, Microsoft Cloud Disk, and Amazon Cloud Disk; and large-capacity email spaces, such as QQ Space, Fetion Space, etc. In the prior art, cloud disks are mainly realized through the following three storage technologies: First, the storage technology of Storage Area Network (SAN, Storage Area Network) is realized based on the optical fiber network with circular threaded (FC) interface, referred to as FC-SAN storage technology; second, SAN storage technology based on Internet Protocol (IP, Internet Protocol), referred to as IP-SAN storage technology; third, distributed file system. [0003] However, the above three storage technologies have the following problems: [0004] (1) The input and output (I / O) performance of the distributed file...
