Frequently Asked Questions about this Class

  • What do I get out of this class?
    • At the end of this class, you will have a deep understanding of Pacemaker and the existing storage strategies. You will be able to name their differences and you will know what storage solution works best for a certain setup - be it a storage cloud, a virtualization cluster, a scaled-out database service, you name it.
  • I am new to High Availability. Is this class for me?
    • If you are a complete novice, then likely, it's not. You should have a good understanding of Linux high availability and clustering concepts, else you won't be able to make the most of this class. There are a number of other training offerings on the market for high-availability novices.
  • I don't run DRBD. Is this class for me?
    • By all means, yes. We do cover DRBD, but this class is by no means DRBD centric.
  • I run servers on Red Hat Cluster. Is this class for me?
    • If you are planning to migrate to Pacemaker in the future (and you should), and you have a good level of hands-on expertise with Red Hat Cluster, then definitely so.
