Hey everyone. I've been browsing the docs for setting up a clustered environment with HA and I had a few questions. First off, I think it's absolutely awesome how easy it is to set up a cluster. It took longer to create a Windows VM to test live migration than it did to create the cluster.
The next step is HA, and that's where I get a little hazy. The docs say that I need a fencing device, and an example given was a $600 APC PDU. Are these devices actually required, or are people able to roll their own completely software solution?
If they are required, how do I shop for PDUs and UPSs with this feature? Fencing doesn't seem to be a searchable feature on Newegg or refurbups.
If a completely software option is viable, does anyone have any examples of how to do it that they can point me to?
