The all new s6500 4U chassis can accommodate up to eight half-width servers. It gives you the ability to mix and match server nodes, and also allows for single node serviceability (SNS) - making it an extremely flexible chassis. This means that you can add or remove compute capacity based on your business needs. The highly efficient multi-node chassis with shared power and cooling components, including energy efficient fans and optional hot-plug redundant PSU helps reduce power consumption to a large extent when compared to previous generation servers.
