HP Common Slot (CS) Power Supplies share a common electrical and physical design that allows for hot-swap, tool-less installation into HP server and storage solutions. CS power supplies allow users to "right-size" a power supply for specific server/storage configurations and environments. This flexibility helps to minimize power waste, lower overall energy costs, and avoid "trapped" power capacity in the data center. A key part of the HP Thermal Discovery Services, CS power supplies provide a high level of power efficiency (94%), helping customers to reduce power requirements by up to 60W per server and reducing overall data center power requirements by up to 10%. CS power supplies also enable HP Power Discovery Services which focus on increasing compute density while reducing data center outages.
