The presentation will begin with an overview of the current Linux clustering landscape. Next it will detail the Kimberlite implementation developed and released as GPL by Mission Critical Linux. We will discuss the practical uses for deploying Linux clustering for increased availability, management flexibility and response time. A Kimberlite Cluster provides support for two server nodes connected to a shared SCSI or Fibre Channel storage subsystem, in an active-active failover environment. The software provides the ability to detect when either node leaves the cluster, and will automatically trigger recovery scripts which perform the procedures necessary to restart applications on the remaining node. When the node rejoins the cluster, applications can be moved back to it, manually or automatically, if required. Sample recovery scripts are provided. Kimberlite is designed to deliver the highest levels of data integrity and be extremely robust. It is suitable for deployment in any environment that requires high availability for un-modified Linux applications.


Tim Burke is the cluster architect and project leader of the team of developers at Mission Critical Linux who developed Kimberlite. Previously, Tim worked at Digital and was a team leader on the Digital UNIX TruCluster product. He has been working on Unix related kernel and middleware products for over 13 years.
