The demands of achieving greater performance while trimming budgets face all HPC professionals today.
Strategies for coping with escalating power and cooling requirements in HPC hardware are in the spotlight. What is needed is a next-generation cooling system that provides the performance today’s data centers require while delivering exceptional efficiency and density.
The answer to putting the brakes on the skyrocketing cost of data center cooling is to leverage the properties of water. Direct contact liquid cooling (DCLC™) is a technique that uses the exceptional thermal conductivity of liquid to provide dense, concentrated cooling to targeted small surface areas.
In addition to serviceability, monitoring, redundancy, and failure isolation, DCLC offers four key benefits:
Attempts to improve cooling have become one of the biggest expenses in the data center. Lowering the cost of cooling with DCLC is a practical, simple way to reduce operating expenses.
This high-density solution requires less standard data center equipment such as racks, switches and raised floors, lowering overall CAPEX. OPEX is decreased by 25%-30% due to reduced chilled water requirements when using warm water cooling. The average ROI for CoolIT’s DCLC™ is less than six months.
Liquid cooling allows each rack to be fully stacked with servers that have multiple CPUs and GPUs, providing high performance in as little space as possible. Density increases can happen on the server or the data center level. CoolIT’s Rack DCLC™ allows for rack densities of 45kW or greater per rack.
A flexible DCLC™ design will accommodate a variety of server design, rack architecture and data center environments, making for a pain-free upgrade. It also allows data center managers to transition to the new solution in stages – adding units to match the addition of new HPC systems and avoiding the costs associated with deploying unneeded cooling infrastructure.
While CoolIT has standard products, the majority of the solutions are tailored to each customer’s unique needs and requirements. Many other competitors have standard offerings with minimal flexibility in product deployment. Other products, including in-row, require certain consistencies in order to operate effectively (rack depth, non-traditional floor spacing, space for external cooling/distribution equipment, etc).
Rack DCLC™ can adjust and accommodate for any number of environmental conditions. The three module approach (Server, Manifold, and CHx or AHx) allows for exceptional flexibility.
It is well known that minimizing noise levels in the work place leads to increased productivity. This also applies to data centers. As the number of servers within a data center increases, so does the number of fans to keep them cool along with fan speed, further adding to the noise threshold. Air cooling is certainly not ‘working’ when it comes to meeting acceptable levels of acoustic noise. Integrating efficient liquid cooling solutions largely removes the dependency on fans and allows data centers to operate at safe acoustic noise levels.
