Lenovo ThinkSystem SD650

Brand: Lenovo
Model Number: SD-650

The SD650's direct water cooling design delivers maximum performance, extreme density, and leading energy efficiency in the data center.
The ThinkSystem SD650 direct water cooled server is an open, flexible, and simple data center solution for users of technical computing, grid deployments, analytics workloads, and large-scale cloud and virtualization infrastructures. The direct water cooled solution is designed to operate by using warm water, up to 50°C (122°F). Chillers are not needed for most customers, meaning even greater savings and a lower total cost of ownership. 
Now with second-generation Intel Xeon Scalable processors, the ThinkSystem SD650 server and the n1200 DWC enclosure are designed to optimize density and performance within typical data center infrastructure limits. The n1200 DWC enclosure is a 6U rack mount unit that fits in a standard 19-inch rack and houses up to 12 water-cooled servers in 6 trays.

The ThinkSystem SD650 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.

Benefits of this solution include:

  • Superior heat conducting efficiency of water versus air, so critical server components operate at lower temperatures compared to air-cooled systems.
  • Running Intel Xeon Processor Scalable family CPUs up to 240W+ versus traditional air-cooled systems limited to 165W-205W.
  • Delivering greater performance with 30-40% data center energy savings.
Did you know?

The ThinkSystem SD650 server and n1200 DWC enclosure with direct water cooling provide the ultimate in data center cooling efficiencies and performance. You can obtain upwards of 40% energy savings in data center expenses with the reduced need for air conditioning and air chillers. Direct water cooling means that the processors installed in the servers can enable the Intel Turbo Boost performance feature more often to further increase processor performance.
