Embodiment Construction
[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0021] see figure 2 , figure 2 This is a flowchart of a data access method based on a distributed file system according to an embodiment of the present invention. The distributed file system includes multiple client devices, metadata servers, and multiple storage service nodes. Each network port is configured with an independent IP address, and each network port of each storage service node is configured with an independent IP address; this method is applied to any client device (such as figure 1 client 1) in figure 2 As shown, the method specifically includes the following steps:
[0022] Step 201: Establish an IP connection pool from the client device to the storage service node in advance based on the IP addresses of ...

The invention provides a data access method and device based on a distributed file system. in the distributed file system, each network port of each client device is configured with an independent IPaddress, and each network port of each storage service node is configured with an independent IP address; The method is applied to any client device, and comprises the following steps: establishing anIP connection pool from the client device to a storage service node in advance based on the IP address of each network port in the client device and the IP address of each network port in each storage service node; Receiving a data access request of a user; Determining each target data block of the data access request; And for each target data block of the data access request, requesting a metadata server for a storage service address where the target data block is located, and accessing the target data block of the storage service address based on an IP link pool from the client device to the storage service node where the storage service address is located.
Description
technical field [0001] The present invention relates to the technical field of storage, in particular to a data access method and device based on a distributed file system. Background technique [0002] see figure 1 , figure 1 is the architecture diagram of the prior art distributed file system, such as figure 1 As shown, the distributed file system includes multiple client devices, metadata servers, and multiple storage service nodes. Wherein, each storage service node has one or more disks, and these disk spaces are uniformly addressed in the distributed file system. [0003] The data access (including reading data and writing data) process of the existing distributed file system is as follows: the user sends a data access request to the client; after the client receives the above data access request, it sends a request to the metadata server to obtain the data access request The storage service address where the target data block is located; the client accesses the ta...
