User Guide

Welcome to the User Guide for Wandisco Fusion.

1. What is WD Fusion?

WD Fusion is a software application that allows Hadoop deployments to replicate HDFS/HCFS data between clusters that are running different, even incompatible versions of Hadoop. It is even possible to replicate between different vendor distributions and versions of Hadoop. Powered by our patented Active Transactional Data Replication ® technology, Fusion keeps data consistent across different data centers no matter where they are in the world. ... It means all your hardware is used all the time as you read and write to any data center.

Benefits

  • Virtual File System for Hadoop, compatible with all Hadoop applications.
  • Single, virtual Namespace that integrates storage from different types of Hadoop, including CDH, HDP, EMC Isilon, Amazon S3/EMRFS and MapR.
  • Storage can be globally distributed.
  • WAN replication using WANdisco's patented active-active replication technology, delivering single-copy consistent hdfs data, replicated between far-flung data centers.

For more information read the Glossary and our website Resource Library.
