Lenovo Neptune™ technology

The ThinkSystem SD650 V2 with Lenovo Neptune Direct to Node (DTN) technology utilizes warm-water cooling (up to 50⁰C) to remove heat from the CPUs, memory, I/O, local storage, and voltage regulators. Because water provides superior heat removal compared to air, the critical components all operate at lower temperatures, delivering greater performance and density in quiet, energy efficient system.

Greater performance, density

The ThinkSystem SD650 V2 is powered by dual 3rd Gen Intel^® Xeon^® Platinum processor CPUs. Because of Neptune™ liquid cooling technology, it can run CPUs up to 270W in a compact, 1/2U form-factor, compared to 165-205W CPUs for air-cooled 1/2U systems. A single rack of ThinkSystem SD650 V2s can deliver half a Petaflop of compute power without using accelerators.

Quiet efficiency

Because water cooling keeps the components cooler, the ThinkSystem SD650 V2 does not have fans, which are a major consumer of energy. Customers who have implemented Neptune™ DTN systems have estimated up to 40% savings on energy costs. Removing the system fans eliminates the fan noise, providing nearly silent operation.
