WANdisco’s patented replication technology enables workload to be balanced across multiple active peer NameNodes that simultaneously support client requests and continually synchronize across any number of data centers any distance apart. Clients have LAN-speed read/write access to the same data at every location without downtime or data loss. Support for rolling upgrades eliminates downtime when new versions of Hadoop are deployed. These capabilities meet the most stringent regulatory and business requirements for data availability and disaster recovery.

Cluster zoning enables a ‘virtual cluster’ or zone within a cluster to be deployed that isolates the most resource intensive data load and in-memory applications to the highest spec servers, while less critical batch applications run on low-end commodity servers. This offers significant cost savings by eliminating the need to deploy high-end servers throughout a cluster, while maintaining quality of service for all users.

WANdisco's selective replication gives you full control over data location, including the unique ability to pull data on demand. Selective replication lets you use network bandwidth efficiently while still presenting a unified view of data for roll-up analysis for authorized users and physically isolating sensitive data to secure clusters.
