Better Air-Cooling Starts with the Basics
At the core of ChilliRack technology is a relatively simple process that brings cold air directly into the rack, sourced either from the raised floor below or from an overhead AC plenum. Improved air flow is achieved with the help of a powerful intake fan, pushing cold air through all the servers in the rack, and an exhaust fan rapidly removing hot air, which is channeled to the return duct above.
Through this cooling method, ChilliRack quickly lowers internal temperatures of every server in the rack, and reliably maintains temperatures at much lower heat levels than today’s air-cooling technology can support. As a result, equipment performs optimally, risk of failure is greatly reduced and server life expectancy is extended.
Ready to address today’s growing heat removal needs
ChilliRack is capable of handling the cooling needs of today’s rack-based equipment. No modifications to IT equipment are needed, so equipment owners can easily make a full transition to ChilliRack when the time is right.
ChilliRack greatly improves cooling efficiency, providing cost savings while cutting power consumption, and reducing the amount of cooling equipment required throughout the data center. By adapting easily to current cooling equipment, costly and time-consuming infrastructure modifications are avoided, and transition to ChilliRack can occur swiftly.
Unlike many complicated and expensive cooling technologies, ChilliRack is extremely cost-effective, with big cost savings driving a quick ROI, making it easy to cost-justify moving all of a company’s equipment to ChilliRack – not just high density HPC servers.
Optimizing data center server capacity
Ineffective air-cooling is the primary factor preventing data centers from maximizing their total server capacity. With the amount of heat generated by today’s equipment often exceeding the cooling capabilities of internal fans, equipment owners are forced to leave a good bit of open rack space between servers as a heat buffer. This spacing can help prevent overheating, but it comes at a cost. Some estimates suggest that the average rack utilization in a typical data center is less than 50% of the rack’s total potential server capacity, driven largely by excessive heat levels.
With ChilliRack, cooling needs are extremely well addressed, in most cases allowing equipment to occupy every RU in the rack. Simulations by Black & Veatch, verified through extensive testing, have demonstrated that ChilliRack users can “pack the rack” from top to bottom, with confidence that every server will be cooled better than ever before possible in today’s racks, which rely upon the internal server fans (along with server spacing) to perform the cooling task. The added boost provided by ChilliRack’s intake fan, combined with the swift removal of hot air by the exhaust fan provide the cooling reliability needed to make full rack utilization possible.
For data centers currently utilizing less than 50% of each rack’s equipment capacity, transitioning to ChilliRack could potentially double the amount of equipment that can be supported throughout the data center. This represents a huge opportunity to increase the number of customers served within a given facility, which results in additional revenues, cost savings and operating efficiencies.
