Abstract

The invention discloses a data access method based on a BCube(n,b) data center. The method is applied in a multi-copy system, and includes the steps of determining at least one group of first nodes, wherein the numbers of all bits between every two first nodes in each group are different; determining a transmission route between a second node and each first node according to the second node and the first node; transmitting the data stored in each second node through the corresponding transmission route to the corresponding first node in parallel. Through the method, parallel transmission of the data can be realized, the data transmission time is saved, and the data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of data transmission in data centers, in particular to a BCube-based ) Data access method of the data center. Background technique [0002] In recent years, global data is growing explosively. According to the statistics of the International Data Corporation IDC, from 2010 to 2020, the global data volume will increase by 50 times, and it is expected to reach 40ZB. At the same time, the demand for data storage is growing at a rate of 50% to 62% per year. This growth places higher demands on the reliability of data center storage. Take the Hadoop cluster deployed by Facebook as an example. The entire cluster has 3,000 nodes and involves 45PB of data. On average, 22 nodes fail every day, and the highest number of failed nodes in a single day exceeds 100. How to ensure the reliability of data has become the primary issue of the data center. [0003] BCube data center is a new server-centric topology proposed by Micr...
