Please what type of SSD are you using for Journals and OSD?

Hello Jinjer, What kind of CPU and RAM size do you have on each of the 4 nodes ?

I am just about setting up something like this. Please what was the spec of the servers and how many VMs did you have on this cluster. Was it very stable in production?

I see your angle on the memory and cpu usage if Ceph and VM are on the same nodes. So what would you suggest as an optimal design. Essentially, I need to be able to host VMs and ensure "high availability" or some form of quick fail-overs in case of a node failure due to whatever reason. I am...

Thank you @udo. Yes, I plan to do all full SSD on all 3 nodes. The reason I was asking if 3-node-ceph is sufficient HA is because I can see there is just another HA how-to here https://pve.proxmox.com/wiki/High_Availability_Cluster_4.x I don't know if this MUST be done to achieve real HA or...

Hello, I am trying to deploy a HA Hypervisor with Proxmox to host a few VMs (50+) I was reading about CEPH on https://pve.proxmox.com/wiki/Ceph_Server and it seem like what I really need. Now my concerns are; 1. Must all the 3 server be exact replicas in CPU (& Cores) Disk and RAM? 2. Is...

Will Kernelcare work for any Proxmox installations or only those with paid subscriptions?
