A heterogeneous cluster allows organizations to mix different bare-metal instance types to satisfy diverse workload requirements, such as combining compute-heavy and storage-heavy nodes. According to Nutanix architectural guidelines for NC2 on AWS, administrators can mix amaximum of 3 different instance typeswithin a single cluster. This limitation ensures that the Distributed Storage Fabric (DSF) can maintain predictable performance and balanced data distribution across the varied hardware. When designing such a cluster, it is also vital that the number of nodes of each type is a multiple of the Replication Factor (RF) to ensure data redundancy is maintained. Mixing more than three types could lead to significant performance skews and complex management of hardware affinity rules.
