Three Places Rack PDUs Capture Power Data From and Why You Should Care

One aspect of intelligent rack PDUs that’s often poorly understood is where the devices are actually capable of capturing power data from;  And more importantly, the distinct advantages to monitoring the power drawn from IT devices, PDU breakers, and branch circuits that can help you to develop energy efficiency standards and lower the risk of unplanned downtime.  So when monitoring power via rack PDU, consider the advantages of monitoring at the outlet-level, PDU breaker, and PDU branch circuit. 

On Switched Rack PDUs and Decreasing Energy Consumption in the Data Center

There are a lot of ways to decrease energy consumption in the data center; everything from building hot/cold aisle containment systems, to distributing higher voltages at the rack, to eliminating voltage step-downs, to building a brand new facility in a Scandinavian country and using airside economizers to cool equipment.  The obvious downside with any of these is that they may require a big overhaul of your existing infrastructure, disrupt operations, or be too costly to undertake.

Switched PDUs are a lower cost solution that can easily fit into an existing infrastructure or be a part of a new data center build. Most importantly, they tackle several issues in one shot.

A couple of months ago, we showed you Raritan's Dominion KX III going head-to-head with its predecessor, the KX II.  Now it’s time to see how the KX III fares against another competitor’s KVM-over-IP switch. Let us know what you think in the comments below. 

KVM Switches vs. Software-Based Remote Access Tools

Many organizations rely on either enterprise KVM switches or software-based remote access tools to control multiple computer systems, often over geographically dispersed areas. While there may be some overlapping capabilities when it comes to mundane everyday activities such as server routine maintenance, both systems have inherent strengths and weaknesses that are important to assess before committing to one over the other. 

Metered PDU vs. Basic PDUs, and Advice on Power Load Balancing

Greg More

Basic rack PDUs are little more than outlet strips. They deliver electrical power to IT devices and that is about all they do.

In addition to delivering electrical power, metered rack PDUs provide information about the power that is being consumed. It may be as simple as the voltage and the power being consumed by the PDU in total or it may provide much more power information and breakdown that information by each individual outlet. There is a wide range of PDUs that could fall under the description of a metered PDU.
