WANdisco Releases Non-Stop NameNode WAN Edition for 100% Global Uptime, Performance and Scalability

WANdisco Hadoop Solution Addresses Enterprises With Worldwide Cluster Deployments

SAN JOSE, CA--(Marketwired - Jun 26, 2013) - Hadoop Summit, Booth 50 -- WANdisco (LSE: WAND), a provider of high-availability software for global enterprises to meet the challenges of Big Data and distributed software development, today announced Non-Stop NameNode WAN Edition, bringing to the wide area network the same unique patented NameNode replication available over the LAN.

Non-Stop NameNode WAN Edition applies WANdisco's patented replication technology to deliver 100% uptime by eliminating Hadoop's most problematic single point of failure -- the NameNode -- to provide the first and only continuous availability solution for globally distributed Hadoop deployments. With Non-Stop NameNode WAN Edition, if a single NameNode server or an entire data center goes offline, Hadoop is still available.

"This new product is a major breakthrough for Hadoop Big Data," said David Richards, WANdisco CEO. "It is the only solution available that isn't geographically limited. WANdisco is the first to come to market with a product capable of supporting Hadoop clusters that span multiple data centers thousands of miles apart."

With Non-Stop NameNode WAN Edition all NameNode servers in a Hadoop cluster deployed over a WAN actively support clients at each location and along with the data nodes, are continuously synchronized. The result is LAN-speed performance and access to the same data at every location with automatic NameNode and data node failover and recovery both within and across data centers, enabling 100% uptime with unparalleled scalability and performance. 

"When it comes to running mission-critical Big Data applications on Hadoop, continuous and uninterrupted cluster availability is a key requirement," said Jeff Kelly, Big Data Analyst, Wikibon. "This becomes significantly more difficult as large enterprises scale-out existing Hadoop deployments across worldwide data centers. WANdisco's Non-Stop NameNode WAN Edition is designed specifically to address this challenge, ensuring that geographically distributed Hadoop deployments remain available to mission-critical applications at all times, even if an entire data center goes down."

Features of Non-Stop NameNode WAN Edition include:

  • 100% Hadoop Uptime over the WAN - WANdisco's continuous synchronization and client support optimized for use over a WAN.
  • Automatic WAN Backup, and Failover - Eliminates the need for network attached storage devices, load balancers and utilities like distcp by turning each NameNode into a fully replicated mirror of others in the cluster for guaranteed backup and failover without interrupting real-time or MapReduce and other batch application access.
  • Complete WAN NameNode Sync - Non-Stop NameNode WAN Edition avoids data loss and split-brain scenarios caused by active/standby backup solutions by applying WANdisco's patented active-active replication to all NameNodes for guaranteed data access and recovery.
