Compatibility between Jasper Lake and Skylake architectures for a proxmox cluster

Hello, i will have compatibility problems with 2 nodes with different cpu architectures (Jasper and Sky Lake) in a homelab proxmox cluster? I currently have an Beelink with celeron N5095 and i want to add a second node with a i3-6100/6100t. Beside that, the second node i think it will have a 2,5in SATA III SSD (256 GB), the Beelink having an M2 SATA III (128 GB). RAM both will have 16gb DDR4 (probably different frecquencies, but as far as i know it will run at the lowest frecq).

I'm kinda new to this, the plan for the final set-up (hopefully :)) will be 3 different nodes in a cluster, every single one with a secondary 1 TB SATA III SSD, each one with a ZFS pool in a RAID 5, i also want live migration between nodes in case of a failure.

I'm waiting for some opinions/suggestions, thank you!
 
Ok, noted. So if i set the CPU type to the i3 mini mini pc node, it shouldn't be any compatibility problems? I'm asking to be sure before purchasing another hardware.
 
No, you won't have compatibility problems. As explained in the documentation on CPU Types, only live migrations between CPUs from different vendors cannot be guaranteed - that is, clusters that contain both Intel and AMD processors. Since you only have Intel CPUs, this won't be an issue.

Since you mentioned that you're kinda new to this, I can also recommend reading the chapters on Migrations and Clusters.
