The Lenovo ThinkSystem SD665 V3 dual-node tray is designed for High Performance Computing (HPC), large-scale cloud, heavy simulations and modeling.
It supports Lenovo Neptune™ Direct Water Cooling (DWC) 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 SD665 V3 provides the optimal balance of serviceability, performance, and efficiency.
By using a standard rack with the ThinkSystem DW612S enclosure equipped with patented stainless steel drip-less quick connectors, the SD665 V3 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™ direct liquid cooling 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 SD665 V3 direct water cooling:
- Reduces data center energy costs by up to 40%
- Increases system performance by up to 10%
- Delivers up to 95% heat removal efficiency§
- Creates a quieter data center with its fan-less design
- Enables data center growth without adding computer room air conditioning
Maximum Performance, Simplified Management
Designed to run the highest core-count 4th Generation AMD EPYC™ Processor, the SD665 V3 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.
The 4th Generation AMD EPYC™ Processors combine both superior memory bandwidth capacity and core-counts that are capable of increasing performance across all HPC workloads.
The 4th Generation AMD EPYC™ Processors excel in HPC application and workloads that are memory sensitive, scale well to multiple cores, and are not highly vectorized applications within the manufacturing/computer-aided engineering (CAE) and weather/climate verticals like OpenFOAM, ANSYS Fluent, ANSYS CFX, ANSYS LS-DYNA, Siemens STAR-CCM+, MOM5, and WRF.
For even greater system performance, the SD665 V3 uses 4800MHz DDR5 memory and supports NVMe storage, high-speed NDR InfiniBand.
The Lenovo ThinkSystem SD665 V3 is enabled with Lenovo HPC & AI Software Stack, so, you can support multiple users and scale within a single cluster environment.
Lenovo HPC & AI Software Stack provides our HPC customers you with a fully tested and supported open-source software stack to enable your administrators and users with for the most effective and environmentally sustainable consumption of Lenovo supercomputing capabilities.
Our Confluent management system and Lenovo Intelligent Computing Orchestration (LiCO) web portal provides an interface designed to abstract the users from the complexity of HPC cluster orchestration and AI workloads management, making open-source HPC software consumable for every customer.
LiCO web portal provides workflows for both AI and HPC, and supports multiple AI frameworks, allowing you to leverage a single cluster for diverse workload requirements.
One 6U ThinkSystem DW612S enclosure accommodates up to 12 SD665 V3 compute nodes. With up to 6 chassis in a traditional 42U rack, the enclosure houses up to 144 processors, 216 TB of DDR5 Memory, and up to 144x PCIe Gen5 x16 adapters on just two data center floor tiles. The ThinkSystem SD665 V3 offers more than 3X the cores per U than the previous generation SD650 V2 server.
Savings and Efficiency
With up to 95% heat removal efficiency, the ThinkSystem SD665 V3 provides up to a 40% savings in data center energy expense including:
- 25% reduction in annual air conditioning use
- 5% energy savings by running cooler CPUs
- 5% savings by eliminating fans in the compute nodes
- 5% optimization from Energy Aware Runtime
A large supercomputing center reusing hot water from direct water cooling can save an estimated 45% in electricity costs.
