How similar does the hardware have to be for a Hyper-V Server 2016 Failover Cluster

Question

I would like to create a 2 node Failover Cluster with 2 Cisco B200 M3 Blades. There are some "small" differences in their hardware though and I'd like to know if this will prevent me from building a Hyper-V Server 2016 Cluster before I have the opportunity to run the Cluster Validation Tool.

Right now, one of the hosts is part of a 4 node 2012 R2 Failover Cluster and the other Blade is running ESXi and a few VM's so it will take quite a bit of work to get the Hyper-V Node Evicted, installed with Hyper-V 2016 and Migrate VM's off of the ESXi Host and rebuild it with Hyper-V Server 2016

Blade 1 has 98 GB of RAM and Blade 2 has 128 GB of RAM
Blade 1 has 2 Xeon E5-2680 2.7 GHz Blade 2 has 2 Xeon E5-2665 2.4 GHz

TIA for any help or guidance on this

Answer 1

Hi,

Since Xeon E5-2680 and Xeon E5-2665 only differ in frequency, there's no problem having them on different nodes in the failover cluster. However, considering possible failover, you have to make sure that 98 GB of RAM on Blade 1 is sufficient.
