TACC Doubles Down on Liquid Immersion Cooling, GRC Delivers Another Immersed HPC Cluster Solution

Posted by Dhruv Varma on November 10, 2017

Green Revolution Cooling provides the Texas Advanced Computing Cluster with new GPU-based servers that leverage the cost benefits available with immersion cooling.

Green Revolution Cooling (GRC) today announced that it will be delivering a custom GPU-based cluster to the Texas Advanced Computing Center (TACC). TACC has been a long-time advocate and user of GRC’s immersion cooling technology dating back to 2009, when the technology was first brought to market. The installation has expanded over the years to include more racks and this new order will further build on the existing deployment.

GRC Named One of the Top 25 DataCenter Tech Companies by CIO Applications Magazine

Posted by Dhruv Varma on November 10, 2017

Green Revolution Cooling (GRC) was recently awarded a spot on CIO Application's annual "Top 25 DataCenter Tech Companies" list. The companies chosen to be included have proven capable of providing data center solutions that help clients build a competitive advantage and transform their businesses. CIO Applications interviewed GRC CEO, Peter Poulin, for an article accompanying the list. Below is an excerpt from the article in the November edition of CIO Applications:

Increasingly powerful applications are putting new demands on data centers (the Cloud, IoT, Crypto-currency mining, AI, ML, and VR to name a few), high-performance servers are consuming more power and more cooling capacity. Conventional cooling systems are having difficulty keeping up. Modifications to these systems have increased complexity, increased cost, extended the time to install, and made maintenance and operations more costly.These market dynamics run counter to organizational efforts to reduce the cost of IT. By radically simplifying how servers in a data center are cooled, Green Revolution Cooling (GRC) is providing IT organizations with an alternative that materially reduces data center build and operation costs, reduces the time required to expand capacity, and makes ongoing system maintenance easy.

GRC Deploys Immersed HPC Cluster at John Paul Catholic University

Posted by Dhruv Varma on October 24, 2017

GRC's Liquid immersion computing system is the ultra-efficient computing cluster at John Paul Catholic University in San Diego, CA.

[October 24, 2017 – Austin, TX] Green Revolution Cooling (GRC), the leader in immersion cooling, today announced the latest installation of its liquid immersion computing system at John Paul Catholic University (JPCU) in San Diego, CA. The high density cluster made up of industry standard servers optimized for immersion, and built in partnership with Supermicro, exploit the enhanced performance and compelling economic value inherent with GRC liquid immersion technology.

Virtually limitless cooling, industry leading efficiency, and lower upfront cost, made it an absolute no brainer for us,” said Kevin Meziere, VP of Technology at JPCU “the ability to cool over 100kW [per rack] effectively and efficiently, gives us the ability to be more responsive to future technology trends and adopt more powerful hardware without concerns of cooling capacity and costs. Being a downtown campus every square inch counts, so the ability to pack equipment more densly is a huge win.

All You Need to Know About... ElectroSafe

Posted by Dhruv Varma on January 13, 2016
INTRODUCTION:

Today's post continues our series All You Need to Know About... with a "deep dive" into the magical liquid that makes it all possible – ElectroSafe. We'll look at all aspects of our coolant from fire safety to what makes it the perfect liquid for immersion cooling. For further reading, download the ElectroSafe Coolant Fact Sheet and FAQs for a brief one-page overview with information such as the NFPA fire diamond and coolant characteristics such as evaporation rate and density, then give our White Paper on the subject, Submerged Servers in the Data Center a read to discover how safe ElectroSafe really is.


What is ElectroSafe?

The ElectroSafe coolant, used in the CarnotJet liquid cooling system, is a clear, odorless, non-toxic blend of dielectric mineral oils.

All You Need to Know About... Floor Space Optimization

Posted by Dhruv Varma on November 25, 2015
INTRODUCTION:

Whether in planning a retrofit or a greenfield build, floor space utilization in the data center is an important consideration. There are a number of ways floor space utilization is measured for data centers – Watts per square foot, servers per square foot, square feet per rack, etc. Below shows the ways in which GRC's CarnotJet system is able to save valuable floor space in the data center as compared to traditional architectures.

Get More Compute per Square Foot with GRC


Less Infrastructure

The CarnotJet system not only eliminates the need for traditional CRACs, CRAHs, and perimeter cooling, it also helps downsize the power and backup infrastructure proportional to the reduction in peak power.

Denser Layout: No hot and cold aisles

CarnotJet racks are installed back-to-back and end-to-end next to each other. There is no space wasted in creating hot and cold aisles – as compared to traditional air-cooled environments – thereby eliminating each alternate aisle and freeing up space.

Denser Racks: Support more than 100 kW per rack

The ElectroSafe coolant used in the CarnotJet system has 1,200 times the heat capacity of air (by volume). This, along with the superior thermal conductivity and closed loop thermal management, allows for extremely high IT load densities in the racks. In fact, some high performance customers have been able to pack more than 100 kW of IT load in a single rack.

This post only scratches the surface of how efficient, powerful, dense and cost-effective GRC's CarnotJet system is. To read more in-depth explanations and see sample layouts, download our white paper about floor space optimization.
