Sealing Gaps Under IT Racks: CFD Analysis Reveals Significant Savings Potential
Often overlooked, the small space between the bottom of an IT rack or cabinet and the raised floor or slab can have a significant impact on IT inlet temperatures. Such areas are common, as casters and leveling feet under IT cabinets create gaps from half an inch…
Two-Dimensional Computational Fluid Dynamics Analysis of Blanking Panel Solutions
Because air-intake temperature is a known significant factor in IT equipment reliability and availability, Upsite Technologies, Inc. commissioned an independent, third-party organization to study the effect of blanking (filler) panels on airflow patterns…
ASHRAE® -Published Report Finds that KoldLok® Brush Grommets Seal Best, Save the Most Energy
The minimal cost of grommets and the long-term savings potential differences among brands provide clear incentives for data center managers to choose the grommet that provides the lowest levels of leakage and yields the greatest energy savings…
How IT Decisions Impact Data Center Facilities: The Importance of Mutual Understanding
Decisions and actions typically under the jurisdiction of the IT side of data center management can have a profound impact on the mechanical plant functions and resultant operating costs of the data center. By understanding these relationships…
AisleLok® Modular Containment vs. Legacy Containment: A Comparative CFD Study of IT Inlet Temperatures and Fan Energy Savings
Airflow management is one of the most critical parameters for optimizing operations and utilization of the data center. This white paper presents and compares the effectiveness of two types of airflow containment systems, the resultant impact on IT temperatures…
6 Reasons to Specify Air-Sealing Grommets in the Design of a New Data Center
The use of raised-floor grommets to prevent bypass air from escaping the underfloor plenum is a well-known airflow management best practice. Elimination of bypass airflow improves the cooling capacity and efficiency of any data center. This paper will explore the benefits…
Cooling Capacity Factor (CCF) Reveals Stranded Capacity and Data Center Cost Savings
The average computer room’s cooling capacity is almost 3x the IT heat load. Calculating your site’s actual cooling capacity can help you “right-size” your cooling infrastructure. This white paper explains how to calculate, benchmark, interpret and benefit…
Effectiveness and Implementation of Modular Containment in Existing Data Centers
Hot aisle containment and cold aisle containment have been used in computer rooms for years to improve efficiency, increase rack densities and improve overall utilization of the computer room. To date, the data center industry has mainly used hard-wall containment…
Reducing Room-Level Bypass Airflow Creates Opportunities to Improve Cooling Capacity and Operating Costs
The misconception is that managing the openings of a raised floor, or even installing full containment solutions, will eliminate bypass airflow. The truth is that while these solutions solve intake air temperature problems, and may reduce operating costs of IT…
Enclosure Openings, The Often Overlooked “Holes” in Data Centers
Data center operators are turning their attention to aisle-level airflow management strategies. Aisle containment, hot and cold, is becoming more common. However, with all the focus placed on these aisle-level solutions, significant unsealed openings at the rack…
Control Data Center Cooling Costs
It is not uncommon that 40- 50% of a data center’s total electrical load is resultant from cooling equipment; roughly the same fraction of the energy that is used to supply the IT equipment itself. The cooling plant power consumption dominates the critical…
KoldLok Certified Product Testing Report
This paper contains a product testing report by the Uptime Institute of supervised performance testing of the KoldLok Integral Raised Floor Grommet, Model 1010. The testing program had three objectives: 1) What is the KoldLok grommet’s sealing effectiveness…
The Path to Efficient Energy Consumption and Cost Savings in Your Data Center
While the acquisition cost for servers is declining, the Total Cost of Ownership for housing, powering, and cooling them has increased by 500 percent since 2000. Even if an effort has been made to improve airflow management in data centers, many suffer from dramatic…
Reducing Bypass Airflow Is Essential for Eliminating Computer Room Hotspots
This pioneering study determined that high-heat densities and/or inadequate cooling capacity were not the underlying cause of hotspots. The highest percentage of hotspots was found in computer rooms with very light loads. Additionally, between 3.2 and 14.7 times…
