we are trying to setup ACI lab. we have 3 x N9K-C9372PX. which APIC should we buy for lab? can we install APIC on VM or do we need saperate APIC controller server?
Seems like you N9K-C9372PX switches which can be the leaf switches in your ACI fabric. You still need at least 1 spine switch for the ACI fabric to work.
