Description: 

We are evolving from a single service running on a single server, complete with multiple points of hardware and software failure... but to what? With services and platforms that need to be restored before our pagers or Bat Phones ring, the system administrators of today have a need for high availability. Starting with the current realities of modern data centers, this half-day tutorial will explore practical uses of Linux clusters.

Who should attend: 

Linux administrators who are planning on implementing a multi-service fail-over cluster implementation in a production environment. Course attendees should be familiar with the basics of system administration in a Linux environment. At no point will the word "cloud" be used, although novice administrators and gurus alike should leave the tutorial having learned something.

Take back to work: 

The knowledge and ability to create and administer highly available services and filesystems on a Linux cluster.

Topics include: 
  • Linux HA Cluster technology: Corosync, OpenAIS, rgmanager, Conga
  • Data management with shared disk implementations: SAN, iSCSI, AoE, FCoE
  • Node fencing with STONITH
  • Network power switches and IPMI
  • Clustered logical volume management
  • GFS2 filesystems with Distributed Lock Manager (DLM)
  • Service management with failover domains
  • Virtual machines as a cluster service
  • Cluster administration with luci
  • Working with cluster-unaware services
