Subzero has added RCI indicators that give an ‘at-a-glance’ view of the efficiency of your data center cooling program. The RCI or Rack Cooling Index was created by Magnus Herrlin President of ANCIS Inc. of San Francisco California. This methodology is designed to measure how effectively IT equipment racks are cooled and maintained within ASHRAE thermal guidelines and standards. Subzero uses this tool to help our customers understand ways to lower the cost of cooling, all the while maintaining a predictable and reliable cooling solution. Now, in addition to being a low cost and easy to deploy environmental sensor system, the PolarXpress system can now be called Intelligent!
Complete the Containment – Rack IT Up
IT racks represent 60% of any containment solution. That’s why racks with gaps compromise the full separation of supply and return airflow. Subzero rack systems cover the gaps and ensure total air separation.
The Relationship Between Containment and DCiM
The separation of supply and return airflow is a well-known way to create huge efficiencies in cooling IT equipment. Subzero’s average containment project drops the IT intake temperature around 10 degrees. Left alone, the containment POD will deliver a consistent, predictable, and reliable supply temperature with little to no difference from the bottom to the top of the rack, and from one end to the other end of the aisle.
That said, most data center managers are not content with only a sustainable IT intake temperature. Most want the added benefit of the huge energy savings that come from adjusting the temperature and humidity set points. As these set points are moved to levels more in line with the ASHRAE standard another important issue needs to be considered – the ability to monitor and regulate supply airflow as thermal loads change.
Thus the correlation between containment technology and an environmental monitoring system as a function of DCiM.
How Cloud and Virtualization Affect Containment Cooling
The impact of virtualization on the average supply temperature is an important consideration. Virtualization increases the processor and memory resources usage. In layman’s terms, more energy is consumed and thus more thermal load. This means that some rack row configurations can have a significant increase in density while others will be reduced.
The good news is that containment changes the way supply-cooling air is used. Instead of relying on the perforated tile in front of the rack, a contained cold aisle turns the supply air into a large pool of air that each server can draw from at any given time and volume. What is needed is a oversupply of air to ensure plenty of cooling capacity.
Now lets tie it together: containment creates consistent and reliable supply airflow to the known thermal load given that a positive pressure is maintained. Changes in set points can be made to lower cooling costs. The question remains… What happens when the thermal load gradually increases due to changes in equipment or virtualization?
The Answer is PolarXpress™!
PolarXpress is a wireless environmental monitoring system that focuses only on the IT intake. A low cost, easy to deploy system that with it’s superior graphic interface makes it easy to read and understand.
PolarXpress is one third the cost of comparable monitoring programs that require integration into more expensive systems.
Monitor your containment from anywhere! Keep up with environmental changes brought on by new equipment or virtualization.
Intelligent Containment Environment – ICE
Another Subzero innovation is the ICE Door. This intelligent door system can contain the PolarXpress environmental system. In this way both IT and Facilities personnel can access key environmental data and ensure the optimal operating environment.
The ICE Door can also be used by a myriad of applications such as security, inventory control, messaging, calendar, etc…
Containment Monitoring Requires Fewer Sensors
One way to drive down the cost of an environmental monitoring system is by using it in connection with a containment system. Note that one third of the sensors are required.
CDCDP (Certified Data Center Design Professional) – The CDCDP training addresses how to setup and improve key aspects such as power, cooling, security, cabling, safety etc. to ensure a hi-available data center.
DCEP (Data Center Energy Practitioner) – The US Department of Energy has partnered with the data center industry to develop an educational program and accreditation for those working as data center professionals.
Subzero Engineering showcased their continued commitment to saving energy and maintaining best practices by sending two corporate engineers to participate in these advanced learning opportunities and are proud to announce the recent CDCDP accreditation of Rick Lake and the DCEP accreditation of Gordon Johnson.
“Today’s modern data centers are complex and require an enormous amount of knowledge and skill to correctly design, build and operate. From servers to storage, chillers to cooling towers, efficient utilization of electrical power to industry best practices… all this and more demands that those who design, operate, and manage data centers be fully trained to meet these incredible challenges all while maintaining a competitive advantage. Contractors and consultants who work in the data center industry face a similar challenge to maintain a current knowledge base and skill set required to service the data center industry in a meaningful way in order to provide products and relevant services for this dynamic industry.
One of the ways that the data center industry has met this challenge is through embracing certification programs that deliver specific training that provide the knowledge and skills necessary to succeed. The Certified Data Center Design Professional (CDCDP) training program is one such program designed to cover all aspects of data centers. The course syllabus includes topics specific to design, cooling, power, IT equipment, and management; taught over a period of seven days through case studies. The program requires the student to pass a series of five examinations to obtain the certification that is valid for a three-year period, after which refresher courses must be taken in order to maintain the certification.
Subzero Engineering, the industry leader in airflow management products and services, has recognized the relevance of this certification and in 2012 sent two staff engineers to become fully CDCDP certified via the training offered by CNet Services.
As one of those individuals, I am happy to say that the program succeeded in providing relevant and up-to-date information that has increased my knowledge of the data center industry in general. With this valuable information, I feel fully equipped to assist clients make specific, cost-effective and measurable improvements to their operations.”
Rick Lake, CDCDP / DCIM Manager / Subzero Engineering
“My recent experience attending the DOE DCEP training and certification program in Dallas was exceptional. I completed and successfully passed the Level 1 Practitioners (Generalists) program and am now looking forward to putting into practice the training and skills received to perform accurate energy assessments in data centers.
The disciplines covered in the training (IT-equipment, cooling systems, air management, and electrical systems) as well as the experience gained using the DC Profiler Tool will be invaluable with my work at Subzero Engineering of data center containment, air flow management, and data center energy efficiency. Besides having the training and experience now to perform energy assessments in data centers, I look forward to transferring the knowledge received to our customers, data center staff, and my coworkers.
In summary, I feel the recent training and certification received has elevated my standards and awareness in what is necessary in order to further reduce energy consumption levels in data centers and related costs, which in the end translates into more overall savings for our customers.”
