A Stretched Cluster deployment in Cisco HyperFlex is designed specifically for multi-site high availability. It distributes nodes across geographically separated data centers (like Europe and Australia), allowing for: Data protection across sites VM migration and workload mobility High availability (HA) with low RPO/RTO Minimum of 6 nodes (3 per site) is required for redundancy and quorum Standard deployment is single-site only. Edge and ROBO deployments are for remote/small sites and do not support HA across locations.
