Load balancing between servers of different age in vSAN

Hello,

Is there a some kind of balancing mechanism for VSAN when there is a mix servers of different age in one cluster?

Our cluster is currently based on HPE DL380 Gen10 and we want to keep using them but will be adding some Gen12 servers into the mix. The new servers will be configured with the same storage capacity as the old ones, but they will have have performance.

Do I actually need to care about this at all?

I found in the "Automatic Rebalance" feature in the documentation but it is not clear whether it actually takes the considers the performance of given node as a reason for a rebalance.

Thanks
