Hi everyone,
I'm planning to expand my Proxmox cluster, which currently consists of a single node with an AMD Threadripper Pro 7975WX processor, by adding another host. While I only need one host for my workload, I require the additional host for live migration purposes. In my infrastructure, I have critical virtual machines hosting Docker containers that I cannot afford to reboot due to user interactions. However, I anticipate needing to reboot my primary node and would like a backup node to avoid disruptions.
Due to cost constraints, purchasing another Threadripper Pro is not feasible for me. Instead, I'm considering building a new node with an AMD Ryzen 9 7950X processor, which shares the Zen 4 architecture with Threadripper. Additionally, the lower price point of this build, under $2000, is attractive to me. Furthermore, I'll be able to install non-buffered ECC memory, up to 128 GB DDR5, to accommodate my critical virtual machines.
My question for the forum is: what success rate can I expect for live migrations between these two processors? I aim for a 98% success rate, understanding that occasional issues may arise. However, I'd like migrations to occur smoothly without freezes or crashes.
Just a side note, I also have another node with an Intel processor and a QDevice in place to ensure the cluster's coordinated operation and voting. This setup guarantees the stability and consistency of the cluster but does not allow me to make live migrations.
Thank you in advance for your insights.
