To upgrade a four-node HCP G10 cluster to an eight-node cluster, the customer can use additionalG10orG11node models. The HCP platform supports the addition of both G10 and G11 nodes in the same cluster, as they are compatible with each other in terms of architecture, management, and functionality. This allows the cluster to be scaled up by adding more nodes of either model to meet growing storage and performance needs.

When expanding an HCP G10 cluster, it is crucial to use node models that are supported and compatible with the existing cluster configuration, such as G10 and G11.
