Raritan added features to its Dominion PX rack power distribution unit (PDU) solutions - which provide detailed power information, down to the individual outlet level - to help data centers optimize operations and manage energy. The new firmware for the PX intelligent power strips enables companies to gather from servers and other data center IT equipment more useful and more accurate information - including total apparent and active power for devices with multiple power supplies, and kilowatt hour metering for energy cost and charge-back applications.
