Subzero is pleased to announce that the chairperson of the Data Center World Conference suggests our talk on Energy Rebates as one of the top 13 sessions to attend.

Subzero is pleased to announce that the chairperson of the Data Center World Conference suggests our talk on Energy Rebates as one of the top 13 sessions to attend.

Larry Mainers, CEO of Subzero Engineering will be giving a session explaining “How to Apply and Receive Utility Rebates with Environmental Monitoring Systems”. This case study will show how a California data center received a large rebate from PG&E after DCEP trained experts implemented a wireless monitoring system that provided key before and after data needed to verify the energy savings to the utility company.

Please join us and see how Subzero’s DCEP trained engineers can assist you through the entire energy rebate process.

More Than Just Data…

More Than Just Data…


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.
