When expanding an HPE StoreVirtual VSA-based cluster with two additional VSA instances, it is crucial that the new instances have equal or greater capacity compared to the existing instances. This requirement ensures that the cluster maintains balanced performance and storage capacity, preventing any potential bottlenecks or imbalances that could affect the overall performance of the cluster. HPE StoreVirtual VSA is designed to scale out by adding more instances with equal or greater capacity, allowing for seamless expansion while maintaining performance and reliability.
