Lenovo ThinkSystem SD650 V2Datasheet
Liquid cooling innovation for a highly efficient data center
The Lenovo ThinkSystem SD650 V2 dual-node tray is designed for High Performance Computing (HPC), large-scale cloud, heavy simulations and modeling.
It supports Lenovo Neptune™ Direct to Node (DTN) technology as well as workloads from technical computing, grid deployments, analytics, and is ideally suited for fields such as research, life sciences, energy, simulation, and engineering.
The unique design of ThinkSystem SD650 V2 provides the optimal balance of serviceability, performance, and efficiency.
By using a standard rack with the ThinkSystem DW612 enclosure equipped with patented stainless steel drip less quick connectors, the SD650 V2 provides easy serviceability and extreme density that is well suited for clusters ranging from small enterprises to the world's largest supercomputers.
The Lenovo Neptune™ DTN doesn't use risky plastic retrofitting but custom designed copper water loops, so you have peace of mind implementing a platform with liquid cooling at the core of the design.
Compared to other technology the ThinkSystem SD650 V2's direct water cooling:
- Can reduce data center energy costs by up to 40%
- Increases system performance by up to 10%
- Can deliver up to 90% heat removal efficiency§
- Creates a quieter data center with its fan-less design
- Enables data center growth without adding CRACs
Maximum Performance, Simplified Management
Designed to run the highest core-count 3rd-generation Intel® Xeon® Platinum processor, the SD650 V2 powers through demanding HPC workloads. Because water cooling removes more heat constantly, CPUs can run in accelerated mode nonstop, getting up to 10% greater performance from the CPU.
For even greater system performance, the SD650 V2 uses 3200MHz DDR4 memory and supports NVMe storage, high-speed HDR InfiniBand, and Omni Path adapters.
The SD650 V2 is supported by Lenovo Intelligent Computing Orchestrator (LiCO), a powerful management suite with an intuitive GUI, that helps to easily orchestrate large HPC cluster resources and accelerate development of AI applications. LiCO works with the most common AI frameworks, including TensorFlow, Caffe, MxNet, and Neon.
One 6U ThinkSystem DW612 Enclosure accommodates up to 12 SD650 V2 compute nodes. With up to 6 chassis in a traditional 42U rack, the enclosure houses up to 144 processors, 144TB of DDR4 Memory, and up to 144x PCIe Gen4 x16 adapters on just two data center floor tiles. The ThinkSystem SD650 V2 offers up to 48 more cores per U than the previous generation SD650 server.
Savings and Efficiency
With up to 90% heat removal efficiency, the ThinkSystem SD650 V2 provides up to a 40% savings in data center energy expense including:
- A 25% reduction in annual air conditioning use
- A 5% energy savings by running cooler CPUs
- A 4% savings by eliminating fans in the compute nodes
A large supercomputing center reusing hot water from direct water cooling can save an estimated 45% in electricity costs.
