As an IT administrator, Lab or Network Manager, you need to access and control multiple computer systems, perhaps widely dispersed, for routine maintenance as well as for real-time troubleshooting and repair. The tool must enable you to work quickly and securely to access any system regardless of type, brand, or location.

Rack PDU Power Rating vs. Load Capacity

There can be confusion about rack PDU power capacities vs. load capacity. The confusion stems from a misunderstanding of approval agency regulations and from some manufacturers who may use misleading terminology. In North America typical circuits have a maximum current carrying capability, and use circuit breakers or fuses rated at, 15A, 20A, 30A, etc. In other words, a PDU with a 20A fuse will blow or a 20A circuit breaker will trip if a 20A circuit experiences more than 20A of current for some period of time. The period depends on the magnitude of the current and the type of fuse or circuit breaker protecting the circuit.

According to the 451 Group, “A data center infrastructure management (DCIM) system collects and manages information about a data center’s assets, resource use and operational status.”  When that information is provided in meaningful way, IT and facilities management’s decision making is vastly improved, which allows for better short-term management, and long-term planning and investments.  

Single-Phase or Three-Phase Input Power for Rack PDUs

Over the past few years, average power consumption per server has rapidly increased with the adoption of high-power computing equipment like blade servers. The typical power required at a rack has increased from 2 kilowatts to 12 kilowatts and continues upward. In addition, ongoing deployment of densely packed storage, virtualization, and cloud computing results in data centers with greater watts/sq. ft. requirements due to more densely packed racks such as a rack filled with 1U servers. To support new, power-hungry IT equipment, data center managers have to deliver more power to the IT equipment rack. 

Is There Room for Both DCIM and ITSM in Your Data Center?

Information Technology is so fundamental to every business today that every organization needs to establish formal processes to ensure that IT services are continually aligned to the business, and deliver efficient and reliable support over the entire lifecycle of products and services. These processes, commonly classified as IT Service Management (ITSM), may follow a well-known model such as ITIL (IT Infrastructure Library) or, more likely, a set of internally-developed best practices.
