oVirt - let's hyperconverge!

We were asked to come up with a solution to setting up a cluster where storage, management and VMs are running together on small number of nodes. This solution is currently known as hyper converged architecture. This kind of setup seems to be getting quite common in small deployments, but it was not possible to use it and maintain all oVirt reliability features until now. This presentation will be about the system design and issues we encountered while installing the minimal possible reliable cluster using three hyper converged hosts with oVirt as the software stack and Gluster for the storage - all running together in highly available setup across all three nodes.

The talk will cover the following topics:

  • Identifying the failure points of virtual datacenter with separate management, host and storage nodes
  • Highly available storage theory
  • Highly available management theory
  • Applying the high-availability in the context of an oVirt cluster
  • Installation and management of hyper-converged setup
  • Possible issues and things to solve
