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.

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.

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.

The KX III IP KVM switch offers some impressive specs: 1,920 x 1,080 HD resolution with 24-bit color at 30 frames per second; Web-based BIOS-level access and control for eight to 64 servers; security protocols like FIPS 140-2 encryption; smart-card/CAC authentication; IPv6; and DVI/HDMI/DisplayPort/VGA connections for digital and analog video, audio, virtual media, blade server support, and mobile access.
But in an age when software-based remote server management tools (RDP, VNC) and embedded service processors (iLO, DRAC,RSA) are prevalent, why should you invest in a device many IT departments consider old-fashioned?
