  1. ODP Global node cluster model Alexander Kolesnikov RIHMI-WDC, Russia

  2. Cluster software • Used onlyGNU GLP software • Open-source components • VMware ESXi 5.5 • OSCentos 5.x • Heartbeat 3.0 • Pacemaker 1.0.12 • Drbd 8.4 • LCMC 1.5.14

  3. Advantages using cluster • Hardware redundancy for failure of the system resources, the server OS, etc. • Software redundancy in case of failure of the software, operating system, etc. • Constant directory synchronization of the component metadata. • Management of applications and components launch order • Ability to restart the associated application servers and database • Ability to determine malfunction in application servers and databases • .Minimal downtime in the event of a component failure

  4. Examples of real usage • Federal Russian distributed data system (ESIMO) • Russian segment of WIS • IODE Ocean Data Portal (global node)
