    Hyperconverged CEPH: Prioritize CPU over VMs for OSDs?

    We have a 5-Host hyperconverged Proxmox 7.1 with CEPH as VM storage (5 SSD OSDs per host). My understanding is that CEPH I/O highly depends on available CPU power Would it make sense to prioritize the OSD processes over any VM process to have (near-)full CPU power available for CEPH even under...

We have two "hadoop" high density SuperMicro HDD Nodes, purchasing a third...
