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.

One cool and useful feature of the new Raritan website is the KVM Product Selector. Situated on the right hand side of each KVM product page, the Product Selector provides a wealth of information about the Raritan KVM and Access Products. Ever wonder which KX III or SX model is right for you? Which CIMs (server dongles) are available for each Raritan KVM switch? What the heck is the difference between the DCIM-USBG2 and D2CIM-DVUSB? Or what node license packages are available for CommandCenter? The KVM Product Selector can quickly answer all of these questions and provide the important attributes of each KVM product or accessory.

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.

Traditionally, data center operators and IT professionals have used a very simple process to create a safe “A” side to “B” side failover scenario. The process and math are very straight forward. The user decides what a safe threshold is - typically 80% of the total kVA of the enclosure - and divides that value evenly between both rack power strips and their onboard circuit breakers. Due to the relative simplicity of the architecture, this practice can work well in a single-phase, less than 5kVA environment. However, in power kVA environments greater than 5kVA, and more complex three-phase environments that are now typical for blade and high density environments, this practice dramatically increases the likelihood of encountering a cascading failure and creates the additional downside of stranding large amounts of available space, power and cooling resources in the process.

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.
