ECS Warranty on older KVM Switches
ECS Advanced Replacement Warranty // Emerson Network Power (Avocent) and Raritan Computer no longer offer Advanced Replacement Extended Warranties on any hardware labeled as End of Life (EOL) or at its 4 year mark from date of purchaset. Avocent & Raritan both do offer a Trade in program. Please contact us if you are interested in upgrading to the latest technology. Enterprise Control Systems (ECS) has a large number of customers that have purchased Avocent and Raritan KVM switches in the past. Several of our current customers in the public and private sector have requested continuation of the Extended Warranty service.

Airflow Management’s Role in Data Center Cooling Capacity
Airflow management (AFM) is changing the way data centers cool the IT thermal load. In thesimplest terms AFM is the science of separating the cooling supply from the hot return airflow.
AFM’s impact on cooling capacity is huge. This is because the traditional cooling scenario without the full separation of supply and return airflowrequires as much as four times the cooling capacity to satisfy the same thermal load. This creates the unnecessary need for cooling units due to airflow inefficiency.
Data center managers can easily determine the percentage of inefficiency by counting the tons of available cooling capacity and measuring it against the IT thermal load measured in kW.

How Data Center Infrastructure Management Software Improves Planning and Cuts Operational Costs
According to the Uptime Institute (a division of the 451 Group) the market for data center infrastructure management systems will grow from $500 Million in 2010 to $7.5 Billion by 2020.1 IT and business executives have realized that hundreds of thousands of dollars in energy and operational costs can be saved by improved physical infrastructure planning, by minor system reconfiguration, and by small process changes.
The systems which allow management to leverage these savings consist of modern data center physical infrastructure (i.e., power and cooling) management software tools. Legacy reporting systems, designed to support traditional data centers, are no longer adequate for new “agile” data centers that need to manage constant capacity changes and dynamic loads. Some data center operators do not use any physical infrastructure management tools. This can be risky. One operator who only managed...
Three types of UPS Technologies
Online Double Conversion Technology
An uninterruptible power supply using true online double conversion technology provides the highest level of power protection available. The Online UPS converts the 230V input AC mains supply to DC power, which is then used to charge the battery. The DC current flow is then fed through an inverter stage that reconstructs the 230V AC mains output. Because the AC output is completely regenerated, it will be completely free from any mains-borne interference such as spikes and voltage variations. The output voltage and frequency is controlled precisely, thus ensuring a clean and stable sine wave power output. Online UPS are able to withstand large fluctuations on the input voltage before transferring to battery power (typically 276V-184V) thus eliminating unnecessary battery discharges. Upon mains failure, transfer to battery power is seamless - no break. Online UPS also have various failsafe and self-diagnostic features that will instantly transfer the load onto mains power if there is a failure within the UPS hardware, or if the UPS is overloaded.
