Data Center power consumption has long been a concern of budget-conscious IT managers. Today, the continued rapid growth of data center capacity has brought greater scrutiny by policymakers, environmental groups, and customers. Business executives are championing sustainability initiatives to not only reduce costs but meet corporate social responsibility objectives.
Sustainability begins with maximizing operational efficiency, and that requires measurement. Organizations are looking to better monitor power consumption so that they can take steps to improve efficiency.
Customers that have equipment hosted in colocation facilities also see the need to monitor power consumption — albeit for different reasons. In many cases, customers pay a fixed price for a committed amount of power per cage of equipment. They may be charged for 200kW but suspect they’re only using half that amount. By monitoring power, they can determine whether to switch to metered billing or consolidate equipment into fewer cages.
However, many organizations lack the infrastructure needed to properly measure power consumption. Rahi has partnered with Packet Power to offer a means of monitoring power usage while minimizing costs and operational disruption.
Increasingly, data center facilities are using metered power distribution units (PDUs) to monitor power. These rackmount units provide information on voltage, current, active power, apparent power, energy, and power factor. High-quality metered PDUs comply with the ISO/IEC 62053-21 standard and provide billing-grade accuracy.
Power data can be measured at the PDU level or at individual outlets. It helps administrators gain a better understanding of power usage so they can take steps to increase efficiency at the device or rack level. Metered PDUs can also be used to allocate power costs to specific user groups, projects, departments, or business units.
“Smart” PDUs have a network interface that enables data center managers to monitor these metrics remotely. They can also be integrated with data center infrastructure management (DCIM) software and environmental monitoring solutions.
However, replacing legacy PDUs with smart units can be a costly and labor-intensive operation. Packet Power solution allows us to put a device inline between the branch circuit and the rack-level PDU or power strip and obtain real-time power readings. Installing the device takes only a few minutes.
Packet Power also offers solutions that enable us to measure power at the individual device level. This is ideal for lab environments that need to understand the power consumption of prototype devices.
Packet Power’s devices have secure, built-in wireless communications, eliminating the need for a data cable. Administrators can access the data via SNMP, Modbus, Ethernet/IP, MTConnect, or Power Packet’s EMX monitoring software. The data can be accessed through a dashboard or delivered to other applications through APIs.
Systems are made to order and shipped ready to install, cutting electricians’ costs in half. Packet Power’s solutions are designed for retrofit, fitting inline, side-by-side, DIN-mounted, or ad hoc electrical panels from any vendor. A variety of models are available, enabling customers to purchase only the monitoring they need.
Rahi’s data center infrastructure experts can help you determine if it makes more sense to upgrade your PDUs or go with a retrofit solution. If you decide to retrofit, we will work with Packet Power to develop your solution then handle the installation. Let us help you implement a power monitoring system that helps you get a handle on costs and drive your sustainability initiatives.
