    I've been looking all over for an answer to this but haven't been able to come up with an answer.   Can you add RAM to a Hyper-V cluster node?  After bootup will the node see the newly installed RAM and allow it to be allocated?  Same question for CPU?  For VM just wondering if you can start small and had an additional CPU and more RAM if you need to add more VMs.

    Move VMs to another Hyper-V cluster node (Live Migration), put serviced node down, throw in more RAM, power it back and... that's all :) The same about CPU. You need to power down VM to increase it's RAM however.

    Hi,

    Yes, you can power off the node, add more CPU and RAM to it to run more virtual machines. However, please ensure that once the node with more CPU/RAM is fails, other node/nodes have the capacity to run all the virtual machines. For example, the virtual machines on Node01 consume 60GB’s memory, while node02 only has 40GB’s memory. So if node01 fails, node02 will not be able to run all the virtual machines properly.
