Cluster design

[KeyzerSuze]

Hi

I have
3 dell R rack servers - there are in 1 cluster ... they have 10G networking
3 beelink mini me .. 2.5g eth and in 1 cluster
1 laptop standalone proxmox

I'm in the process of migrating all of my disk to the dell servers and the cluster. and attaching the beelink cluster and the laptop cluster to the ceph on the dell cluster.

But i thought why don't i just add the laptop and the beelinks to the dell cluster - I don't have to create OSD on the beelinks or the laptop - but they will automatically get ceph storage access.

is there any issue with have a cluster made of different types of cpu / network (in speed, they have the same vlans) and maybe even potential cpu type ?

and if there isn't any problems or issues how to i migrate a beelink node from the beelink cluster to the dell cluster - do I have to re install ?

Yes, live migration is a problem. Don't expand your cluster, you could get quorum issues.

So i had presumed I could just create resource groups and limit live migration between like nodes.

What sort of quorum issues ?
