      Hi everyone new to the forum, I just wanted to ask about my specific use case, as I am looking to update the CPU's in multiple Dell FC430 servers in my FX2 enclosure. I am wanting to update from the dual E5-2620 V3 to dual E5-2699 V4 CPUs, so going from Haswell to Broadwell since I am looking to gain more cores and performance in the servers. Would I need to update all the servers in my pool to the E5-2699 V4 at the same time, or would I be able to just update one server without it being removed from the pool since the architecture is fairly close ?

        @Nik I did mostly this change with my HP DL360G8 upgrading from E5 v1 to E5 v2. Shut down a machine, swap CPUs, turn on and reconnect to the pool (no changes needed). It was not a problem at all keeping everything running and migrating between new and old systems. There is not much difference between the v3 and v4 CPUs. There may be a few new features in the v4 that you won't see in the pool until all the CPUs are upgraded.

        Don't remove a server from your pool. Just migrate VMs off of it and power it down to do the hardware changes. Check the contact area of your new CPUs. Make sure you have good thermal paste and clean everything. Don't bend a socket pin!

        You should see only about a 15% increase in single threaded (single core) performance but a 325% increase in multi-threaded total performance due to all the new cores. Plus an increase in heat and power usage... Note that the new CPUs can use faster memory so you won't see the full performance increase with the old slower memory.

          Thank you so much, I was not sure if there was a weird quirk between the generations that would cause them to be ejected from the current pool. That simplifies the rest of my upgrade then, first will be the CPU's, and then I will do memory next, just have to wait slightly due to my budget, but looking forward to the uplift for multi threaded. The single core uplift will just be a bonus on top, but I am trying to stretch out this platform for as long as I can get away with. Again thank you for the response much apprciated
