Wiwynn at OCP Summit 2019 with XC200G2 and Immersion Cooling

Wiwynn is a major supplier to CSPs like Facebook which means it had a large presence at OCP Summit 2019. We had a chance to visit the company’s booth at the show and wanted to share two highlights.

Wiwynn XC200G2 PCIe Gen4 GPU Chassis

In the booth, STH was told that this is the first time the company was showing their new PCIe Gen4 GPU chassis. We double checked our coverage and we saw the unit at Computex 2018. See Wiwynn XC200G2 PCIe Gen4 16x Compute Accelerator Machine.

The main difference in 2019 is that we are in eager anticipation of multiple PCIe Gen4 chips hitting the market from AMD Rome, Intel, and Arm server vendors including the Huawei Kunpeng 920 64-Core Arm Server CPU. In 2018 this required an IBM Power system to utilize with PCIe Gen4. In 2019, this will be the type of chassis you will want with new generations of CPUs and accelerator cards.

Wiwynn 2-Phase Immersion Cooling

Immersion cooling was a big topic at OCP Summit 2019. Wiwynn had a 2-phase immersion cooling demonstration in their booth.

CSPs are looking to hit on the order of 100kW or more from smaller space footprints. As a result, liquid immersion cooling is a hot topic and we expect to see it deployed more as we get to the 2020 timeframe. Liquid immersion cooling allows significantly lower power consumption. When CSPs combine the lower power consumption along with the floor space savings by getting higher densities, the economics of immersion cooling is changing.
