CS power supplies are available in multiple high-efficiency input and output options - allowing 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 Platinum/Platinum Plus Power Supplies provide the IT industry’s highest 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% (as compared to Proliant G6 power estimates). CS Platinum/Platinum Plus power supplies also enable HP Power Discovery Services which focus on increasing compute density while reducing data center outages.
