Cluster Network for guest clusters

    Întrebare

  • Is there a downside to sharing the cluster network between guest cluster(s) and/or a Hyper-V host cluster?

    I'm assuming that the only issue would be bandwidth contention (e.g. during a live migration).

  • Hello,

    It is highly recommended to use dedicated networks for different type of traffic (cluster, management, live migration, VM access, etc.). I would recommend checking converged networking, where you can share the same physical network infrastructure for different types of network traffic.

    All that can be provided here is a generic "that should work".  You need to evaluate for your particular environment.  Something like https://www.altaro.com/hyper-v/virtual-networking-configuration-best-practices/ provides recommended practices - keyword recommended.  It's possible that in some situations, a single teamed NIC can handle all the load.  But in other situations, multiple networks are recommended.  For example, in your port, you are addressing only vague performance concerns, and you do not mention security at all.  That is often a reason to separate the host management from the VM management networks.

    So, generically, your proposed configuration will 'work', but we can't say if it is the route to pursue.

  • So how about a guest cluster (i.e. on VMs) which is not requiring direct storage access and isn't Hyper-V. This should only need a cluster network for heartbeat and CSV redirection. Could this share the Hyper-V cluster network (not storage or live migration)?

  • Yes, that should be ok.
