First peta-scale HPC to use warm-water liquid cooling

The Article is taken from National Renewable Energy Lab Picks Xeon Phi

Here are some excerpts from the Article

National Renewable Energy Laboratory (NREL) is the first peta-scale HPC to use warm-water liquid cooling, earning it the world’s number one rating in power-usage effectiveness of PUE=1.06!

The direct-component liquid cooling system supplies servers with warm water (75 degrees Fahrenheit) that is piped over processors to remove excess heat, returning water heated to approximately 100 degrees F. Because only 25 degrees of heat must be removed by the water-cooling system, the energy efficient set-up eliminates the power-hungry compressors needed for traditional air-cooling systems.

Excess heat generated by the new HPC will function as the primary room-heating technology for its Golden, Colo., data center, and will heat walkways outside buildings to melt snow and ice. This holistic approach, defined by the NREL’s Energy Systems Integration Facility (ESIF), will save as much as $1 million per year on power needed to run a conventional air-cooled data center.

Green Revolution cooling announces full factory warranty from supermicro

According to the website announcement,  

Super Micro Computer, Inc. (Supermicro®) is now providing full warranty coverage for servers installed in the CarnotJet™ submersion cooling system. The assurance is a momentous step forward for Green Revolution Cooling and confirms the long-term reliability of servers installed in the CarnotJet™ system.

The warranty will cover motherboards, backplanes, add-on cards, power supplies, and processors for parts and labor. DIMM modules and SSDs are also covered in the warranty, as are all other manufacturer defects discovered during server operation in the CarnotJet™ system.

Lastly, Supermicro® is also offering a line of products available submersion-ready direct from the factory. With Supermicro® servers turn-key and fully guaranteed, it has never been easier to outfit your data center with submersion cooling from Green Revolution Cooling.

Programmable Data Centre

This is an interesting article on programmable data centre titled "The Rise of the Programmable Data Center". To quote the aricle

In order to address these issues, there’s a movement afoot to create the “programmable data center,” where an IT administrator can more holistically manage servers, storage, and networking components. While still in its relative infancy, a number of vendors have expressed interest in the movement’s underlying concepts, all but ensuring its growth in coming years

Data Center Temperature: ASHRAE's Perspective

A interesting article from Data Centre Posts "Data Center Temperature: ASHRAE's Perspective"

On the Moisture Lower Limit
.....A lower limit of 5.5°C (41.9°F) was chosen which corresponded to the lowest absolute moisture level of the 2004 recommended limits.....

On the Moisture Upper Limit 
.....It was found that extended periods above 60% can result in failures. As a result, a relative humidity upper limit of 60% was chosen.....

Green Revolution Cooling (www.grcooling.com)

AT SC10, I saw quite a unique and disruptive solution for cooling HPC stuff. It won SC 2009 disruptive technology of the year.

Green Revolution (GR) Cooling method of cooling datacentre is very revolutionary and innovative. According to Green Revolution Cooling, datacentre are cooled by submerging servers in dielectric fluid coolant (GreenDEF coolant).

According to its website, GR Cooling is the first to develop a complete rack and server rack solution using this method at a feasible up-front costs and high performance.

Intel Data Center Manager Software

Intel® Data Center Manager (Intel® DCM) SDK provides power and thermal monitoring and management for servers, racks and groups of servers in data centers. Management Console Vendors (ISVs) and System Integrators (SIs) can integrate Intel® DCM into their console or command-line applications and provide high value power management features to IT organizations


Intel® DCM features include:

• Built-in policy based intelligent heuristics engine that can maintain group power capping while dynamically adapting to changing server loads and minimizing performance impact of workloads
• Uses Intel® Intelligent Power Node Manager for node power and thermal management
• Designed as an SDK to integrate into existing management software products by means of a web service application programming interface (WSDL API)
