KoldWorks is a suite of specialized engineering and educational services designed by Upsite Technologies® to enhance data center performance without additional capital investment.DCA Consulting focuses on improving the productivity and reliability of electronic equipment in the data center environment through consulting services. DCA Consulting offers power quality expertise for the most complex power problems. DCA offers expertise for all aspects of power quality for the data center environment including EMF, high frequency and RF interference, and those hard to diagnose grounding issues that may be causing intermittent interruptions in the data center operation or network performance. The PUE or Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1. PUE was created by members of the Green Grid, an industry group focused on data center energy efficiency. For your offices, DCA Consulting may not be your first choice to investigate the IAQ however for your data center, DCA Consulting should be your only choice. No one knows more about data centers than we do. We know where to look and what to look for.

	KOLDWORKS KOLDWORKS DCA Consulting is proud to be the Asia representative of Upsite’s KoldWorks cooling services. Increase Data Center Reliability by Optimizing Your Existing Cooling Infrastructure KoldWorks is a suite of specialized engineering and educational services designed by Upsite Technologies® to enhance data center performance without additional capital investment. > Boost data center reliability > Optimize your current cooling infrastructure > Enable precision cooling to reduce or eliminate hotspots > Dramatically reduce bypass airflow > Assist with data center ASHRAE compliance > Learn the dynamics of your data center, including cooling requirements, deficiencies, and the science behind efficient operation Comprehensive Diagnostic and Remediation Computer Room Services As data center rack densities increase and thermal loads rise, many organizations resort to increasing the number of cooling units. While this may appear to solve the problem, the added cooling capacity does not offer precision cooling, which will help curb costs and improve energy efficiency. To achieve cooling efficiency and optimize your capacity, you must eliminate the loss of chilled air through unsealed cable openings, as well as examine other data center performance factors, including the location of perforated tiles, relative humidity, underfloor plenum airflow, computer-room layout, set points and power consumption. With a range of services, you will be able to meet your technical and budgetary requirements. Inadequate supply air volume creates an environment in which equipment at the top of cabinets is significantly hotter. In this photograph, recirculation is evident over the top of the cabinet, around the ends of rows, and within the cabinet itself. KOLDPROFILE Upsite KoldProfile, one of the KoldWorks suite of service offerings, is a survey of your data center cooling to determine the three measurements of data center cooling health based on published standards from ASHRAE and the Uptime Institute: > Data Center Hotspots—Temperature and Relative Humidity > Bypass Airflow—To regain lost conditioned airflow > Cooling Margin Available—To cool additional equipment This service takes approximately 1-2 hours depending on data center size and includes the following activities: > Count & size raised floor openings to estimate the percentage of bypass airflow > Measure cabinet air intake temperatures to determine the presence of hotspots > Measure relative humidity of any identified hotspots > Sum cooling unit rated cooling capacity and convert from tons to kilo watts (kW) > Sum cooling unit rated airflow in CFM (cubic feet per minute) > Sum computing equipment power load in kW > Determine the presence of latent cooling and its associated Latent Cooling Penalty After the survey on the data center floor, you will receive: > On site verbal discussion of findings and recommendations > Written KoldProfile report detailing findings and recommendations KoldProfile is necessary for data centers dedicated to improving IT equipment reliability and optimizing critical physical infrastructure. Learn how capital costs associated with installing additional cooling equipment and operating costs can bereduced, and determine redundant cooling capacity for a high heat density computing equipment installation. KOLDCHECK Diagnose Key Data Center Conditions Examine your data center infrastructure and find out how to regain control of the cooling environment with KoldCheck diagnostic services. Based on what you require, KoldCheck data center experts benchmark your existing conditions and evaluate your computer room to determine ways to optimize your existing cooling investment. Upon completion of the on-site review, KoldCheck engineers present a comprehensive report, detailed with useful data and recommendations for how to solve existing and projected problems cost effectively. Comprehensive Analysis of Key Data Center Conditions: > Cooling conditions—A study of existing cooling conditions, such as rack/cabinet temperatures, measurement of room temperature and humidification patterns, analysis of room recirculation patterns, and benchmarking of cooling unit performance against manufacturer specifications. > Airflow conditions—Analysis of current airflow conditions, including perforated tile layout, underflow airflow, perimeter breaches, and raised-floor bypass area and bypass airflow volume. > Critical power conditions—An examination of current power conditions that compares power consumption vs. system capacity, establishes power distribution limits, quantifies rack utilization. Redundant capacity of each sub system is determined. > General room conditions—An overall assessment that surveys the make-up air system, equipment layout, cabling management, and room contamination (debris, dust, etc .) > Infrared (IR) thermal imaging of IT and cooling equipment Report can include all of the following: A detailed report is delivered to the client approximately three and one-half weeks after the analysis is completed. > Estimate of efficiency improvement with elimination of bypass airflow (how many cooling units could be turned off or relocated to eliminate buying additional equipment for future installations) > Recommendations based on detailed analysis and study of findings including critical vulnerabilities > Fixed-price quote for KoldTune to implement KoldCheck recommendations > General business case analysis to calculate investment and return on investment of implementing KoldCheck recommendations > Calculation of Upsite Coefficient of Effectiveness™ > Tile Flow computational fluid dynamics (CFD) modeling KOLDTUNE Get more cooling capacity from your existing data center infrastructure with KoldTuneSM remediation services. KoldTune goes a step further than KoldCheckSM by solving identified cooling-related problems, which can help you improve the stability, reliability, and efficiency of the data center raised-floor environment. After a KoldTune, your data center will be able to cool more IT equipment with the existing cooling infrastructure and operate more efficiently. Highlights > Remediation plan: After an initial on-site visit to collect baseline information, Upsite designs a remediation work plan and assigns an engineering team. > Airflow rebalancing: The DCA team provides complete airflow rebalancing and custom solutions for sealing all reasonably accessible unmanaged openings in the raised floor. > Perforated tile adjustment: The team adjusts the number and location of perforated tiles. > Cooling unit adjustment: The team recalibrates set points and humidity controls on cooling units, and possibly turns off excess capacity. > Airflow recirculation: The team addresses room and rack airflow recirculation. > General tuning recommendations: The team provides recommendations for general tuning of the raised-floor environment. > Post-remediation analysis: The team analyzes the room after remediation to capture improved conditions. > Valuable reporting: Upon completion, Upsite provides a report that details efficiency improvements, a model of plenum airflow, and recommended practices for future equipment installation and configuration.
