Lenovo ThinkSystem SD650
A direct water-cooled, two-socket half-wide server: two independent nodes on a 1U tray in the ThinkSystem NeXtScale n1200 DWC enclosure, sold first with 1st-generation Xeon Scalable (Skylake-SP) and later updated to 2nd-generation Xeon Scalable (Cascade Lake-SP), for HPC and technical-computing clusters that need warm-water cooling and near-silent, fan-free nodes.
