[0034] Example

[0035] Such as figure 1 As shown, a cloud rendering-oriented distributed file system includes a main management node 1, a rack management node 2 and a storage node 3. There is one main management node 1 and multiple rack management nodes 2 are set up respectively. Connected to the main management node 1, each rack management node 2 is connected to multiple storage nodes 3, and then the main management node 1, rack management node 2 and client 5 nodes form a tree structure, and the storage node 3 stores the corresponding files For data blocks, the rack management node 2 stores metadata information of file data blocks stored in the storage node 3 connected to it, and the main management node 1 stores metadata information of the entire file system. Among them, metadata information includes directory and file metadata information and data block metadata information, directory and file metadata information includes file attribute information, and data block metadata ...

Abstract

The invention relates to a distributed file system for cloud rendering, and construction and access methods. The system comprises one main management node (1), multiple frame management nodes (2) and storage nodes (3), wherein the multiple frame management nodes (2) are connected with the main management node (1), each frame management node (2) is connected with the multiple storage nodes (3), the main management node (1), the frame management nodes (2) and client (5) nodes form a tree-shaped structure, the storage nodes (3) store corresponding file data blocks, the frame management nodes (2) store meta-data information of the file data blocks stored by the storage nodes (3) connected therewith, and the main management node (2) stores meta-data information of a whole file system. Compared to the prior art, the file system provided by the invention solves the problem of single-point failure and is high in stability.

Description

technical field [0001] The invention relates to a cloud rendering-oriented file system and its construction and access method, in particular to a cloud rendering-oriented distributed file system and its construction and access method. Background technique [0002] According to the Internet Data Center (IDC) data, the total amount of digital information as of 2009 was 800,000PB (1PB=10 6 GB), and reached 1.2ZB in 2010 (1ZB=10 12 GB). By 2020, the total amount of global digital information will reach 35ZB. [0003] It is precisely because of the emergence of the Internet that the explosion of digital information has been promoted. In 1996, only 48 million people in the world regularly accessed the Internet. In 2010, there were 1.6 billion Internet users worldwide. These users don't just browse websites, they create vast amounts of unstructured data, including images, emails, and more. In addition to pictures and e-mails, the appearance of instant messages, wikis, and blog...
