Increase Performance While Conserving Energy

Liquid cooling for latest generation Dell EMC PowerEdge servers

The latest generation of Dell EMC PowerEdge servers offers CPUs with higher performance than ever before, providing the capability to run artificial intelligence (AI), high performance computing (HPC) and other advanced enterprise workloads. However, the upward trend toward more powerful, denser computing infrastructure also requires continuing innovations in cooling to keep up with it.

Along with the latest processors, many of the latest generation of more powerful Dell EMC PowerEdge servers also come with the option for CoolIT Direct Liquid Cooling (DLC) technology. DLC transfers heat away from the processors by placing a metal plate in direct contact with the surface of the processor. Liquid flows through sealed micro-channels in the plate to capture heat from the processor and then flows on to a heat exchanger, which dissipates the heat.

The heat load is removed from the data center via a warm water loop, potentially bypassing the chiller system. Because water can hold 4X more heat capacity than air, these new liquid-cooled servers can support higher-bin, faster processors with lower power requirements and greater reliability. By replacing or supplementing conventional air cooling with higher-efficiency liquid cooling, the overall operational efficiency of the data center is improved.

For example, DLC can help:

◉ Enable higher compute density. DLC cooling enables support of up to 25% more cores per rack for the C6520 system and 2X the core count for the C6525 system compared to air cooling alone.

◉ Support system configurations that may not be possible with air cooling alone, such as high thermal design power (TDP) CPUs, dense storage and/or add-in cards.

◉ Reduce energy costs by up to 45% relative to cooled air.

◉ Pay for itself with a 1.3-year break-even and 3X return on investment (ROI) within four years.

With the latest launch, we’re expanding our portfolio of servers with factory-installed DLC to include our dense Dell EMC PowerEdge C6520 and C6525 Servers, as well as the following Dell EMC PowerEdge rack-mount servers:  R6525, R7525, R650, R750, R750XA.

It’s a cool POD, literally and figuratively

Where a node-level DLC solution captures between 50%-60% of a server’s internal heat (depending on the configuration), the rack-level POD is designed for total heat capture. The POD solution contains front and back containment for racks of DLC servers, plus an In-row cooler integrated between the IT racks to capture any remaining heat for even greater cooling efficiency.

Air-cooled cars?

If you’re still thinking you don’t need liquid cooling in your datacenter, consider this: Liquid cooling in automobiles started in 1897 with the invention of radiators. Would you consider buying an air-cooled car? In the heat of summer, dip in the pool and check out Dell Technologies Direct Liquid Cooling Support for New PowerEdge Servers. The Dell Technologies HPC & AI Innovation Lab has dueling air and liquid-cooled racks.
