Mixing Cisco C220 M4 and M5 Nodes in VSAN

[Chadmandu]

All -

I have a customer that has a four Cisco C220 M4 node VSAN cluster looking to add compute/storage in the form of a C220 M5 node.  Are there, or will there be any issues in doing this regarding compatibility?

Thanks in advance

Hello Chadmandu​,

Welcome to Communities.

Yes, it is supported to mix different models of servers in a vSAN cluster - provided that the relevant components in all servers are on the vSAN HCL (controllers, Cache-Tier SSD/NVMe and Capacity-tier HDD/SSD/NVMe) or are ReadyNodes.

Do however aim to configure the servers equally with regard to storage capacity, layout and capability (e.g. don't add a server with twice the storage that is half as performant and expect it to not slow the cluster down).

That's great news!

Thanks for the answer and I will aim to do that!
