Front to back cooling is a method where cool air is drawn in through the front of the server and pushed out the back. Unfortunately heat rises, and the cool air becomes warm as it enters the rack, resulting in inefficient system cooling.The greater the density of a system, the greater the heat production from microprocessors and power supplies. These are the two biggest heat culprits in servers. Processors alone are responsible for 75% to 80% of the heat that needs to be dissipated. As servers continue to increase in wattage and create more heat, front to back cooling becomes less of a viable option for the data center. Front to back cooling leads to data center hot spots, which ultimately leads to system failure.
Data Center Equipment Cooling Methods
Traditional Front to Back Cooling
Front to back cooling is a method where cool air is drawn in through the front of the server and pushed out the back. Unfortunately heat rises, and the cool air becomes warm as it enters the rack, resulting in inefficient system cooling and higher failure rates for equipment near the top.
Front to Top Cooling
Similar to the traditional front to back method, front to top cooling draws air through the front of the rack on both sides of the equipment; however, hot air is pushed up to the top of the rack and expelled. Unfortunately, not enough cold air can reach the top of the racks utilizing this method, and the result is an increased failure rate of components near the top of the rack.
Patented Vertical Cooling
Cold air is drawn into the bottom of the rack and flows over the blade components on each level. The airs moves at a rate of up to 4500 cubic feet per minute to create a high-velocity, powerful cooling engine. Only a 3 degree celsius differential is realized on each level so equipment near the top of the rack functions normally due to the amount of cold air flow.
How It Works
Cirrascale's Patented Vertical Cooling Technology (VCT) creates a high velocity stream of cool air driving away hot air created by high performance components and power supplies. Many blade server and storage installations utilize traditional front to back cooling, which creates hot and cold aisles in the data center as well as causing hot spots that lead to system failure.
Cirrascale's Vertical Cooling Technology is ideal for large scale data centers where floor cooling is efficiently utilized and exhausted into ceiling ducts. Vertical cooling draws cool air up from the floor and forces it through the entire rack and exhausts into the ceiling, creating a constantly cool and secure environment for your data center. Increased thermal capacity has been incorporated into the design, as well as the ability to adjust air flow within the cabinet. Modular and hot swappable fan trays create a stream of air throughout the system.
Our Vertical Cooling Technology Embodies Everything We're About
Enabling Extreme Density
Extreme density is realized as Cirrascale's patented VCT injects over 4500CFM of air throughout the platform providing enough cooling for up to 96 servers per blade platform and 2,880 servers per containerized data center.
Our patented VCT gives Cirrascale's blade platforms some of the lowest failure rates in the industry. In fact, according to our customers, on average our systems experience as much as 50% less failures than our closest competitors.
Cirrascale's Vertical Cooling enables our systems to handle power efficiency at the rack level allowing it to turn the power into compute cycles without expending excess wattage on cooling any unnecessary heat.
The river of cool air running over the common off-the-shelf components within each Cirrascale blade-based solution keeps the systems running cool, allowing them to experience little to no CPU throttling, keeping the power where it can be utilized.
Cure Sick Data Centers
Some find it hard to believe at first, but it's true. Placing a Cirrascale BladeRack 2 Series platform in your data center near third-party equipment struggling for air can help dramatically. Our systems pull air to the area helping deliver a more evened airflow to the struggling systems in the corners of your data center.
