WANdisco Releases Next Version of Non-Stop NameNode WAN Edition

SAN RAMON, CA--(Marketwired - Aug 13, 2013) - WANdisco (LSE: WAND), a provider of high-availability software for global enterprises to meet the challenges of Big Data and distributed software development, announced the next version of Non-Stop NameNode WAN Edition. Non-Stop NameNode WAN Edition 1.1 offers new features that extend the continuous availability benefits already offered by the original solution, announced in June 2013, by allowing new namenodes to be added on the fly without downtime, further enhancing performance and availability, and simplifying management for overall efficiency.

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.

New features in Non-Stop NameNode WAN Edition 1.1 include:

• Dynamic Group Evolution - This provides the ability to add and remove namenodes within Hadoop clusters on the fly without downtime, eliminating the need for scheduled maintenance.
• Configurable Quorum Schema - New node configurations enable increased availability and deployment flexibility for more efficient use of IT infrastructure.
• Rapid recovery for a namenode that has been down for an extended period of time.

"Non-Stop NameNode WAN Edition is designed to meet the 100% uptime requirements of today's enterprises," said David Richards, WANdisco CEO. "The enhancements within this release further ensure mission-critical Big Data applications can scale as workload grows and keep running even if an entire data center goes down."

About Non-Stop NameNode WAN Edition
Non-Stop NameNode WAN Edition applies WANdisco's patented replication technology to provide 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 deployments. With it, 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. Whether a single NameNode server or an entire site goes down, Hadoop is always available.
