Dell ECS Object Storage is architected for scalability and ease of growth. Expansions to Dell ECS Object Storage clusters (VDCs) can be done data-in-place and online, by either adding drives to existing Object Storage nodes (if not already fully populated) or by adding additional chassis to the cluster.
Dell ECS Object Storage requires that all nodes within the cluster have the same number of drives, and same capacity drives. When adding drives or chassis (nodes), it should therefore be understood that this requirement must be maintained following any expansion.
