The KVM Product Selector – A Quick and Easy Guide to the Raritan KVM Switches

Posted on June 30, 2014 by Gento

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.

KVM Showdown:  Raritan’s Dominion KX III KVM-Over-IP vs Leading Competitor

Posted on June 25, 2014 by Gento

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. 

Avoiding Unscheduled Downtime by Removing the Guesswork from Rack Loading

Posted on June 18, 2014 by Gento

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.  

KVM Switches vs. Software-Based Remote Access Tools

Posted on June 16, 2014 by Gento

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. 

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

Posted on June 11, 2014 by Gento

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.
