FAQs

Q: What GPU configurations are supported on the SR670 V2?
A: The SR670 V2 supports up to 8 double-wide PCIe GPUs (such as NVIDIA A100, A40, or A10), up to 8 single-wide GPUs, or up to 4 SXM form factor GPUs. The SXM configuration supports the NVIDIA HGX A100 4-GPU complex with NVLink for direct GPU-to-GPU communication, ideal for multi-GPU AI training workloads.

Q: Can the SR670 V2 support both regular DDR4 memory and Intel Optane Persistent Memory?
A: Yes. The server supports up to 32 DDR4-3200 RDIMMs for a maximum of 4TB system memory. It also supports Intel Optane Persistent Memory 200 Series, with up to 16 PMem modules installable in conjunction with regular DDR4 DIMMs for advanced in-memory database applications and dense virtualization scenarios.

Q: What storage options are available on this server?
A: Storage configurations vary by GPU model chosen. Options include up to 8x 2.5-inch hot-swap bays, 4x 3.5-inch hot-swap bays, or 6x EDSFF (Enterprise and Datacenter SSD Form Factor) bays. All configurations support SAS, SATA, or NVMe drives. The server also supports M.2 SATA or NVMe boot drives in RAID 1 configuration for OS redundancy.

Q: What is Lenovo Neptune cooling and when is it used?
A: Lenovo Neptune is a hybrid liquid-to-air cooling technology designed for high-density GPU configurations. It uses a closed-loop liquid-to-air heat exchanger to dissipate heat from NVIDIA HGX A100 SXM GPUs, delivering benefits such as higher performance, lower power consumption, and quieter operation without requiring data center plumbing or external liquid cooling infrastructure.

Q: What are typical use cases for the SR670 V2?
A: The SR670 V2 is optimized for GPU-accelerated workloads including artificial intelligence (AI) training and inference, deep learning (DL), machine learning (ML), high-performance computing (HPC) simulations, 3D rendering, visualization, VDI (Virtual Desktop Infrastructure), and data analytics in industries such as healthcare, financial services, manufacturing, and research institutions.
