Lenovo ThinkSystem SR675 V3 3U GPU Server
PRODUCT DESCRIPTION
Lenovo ThinkSystem SR675 V3 3U GPU Server (Configure-to-Order) - Local Warranty
3U GPU Server With Dual AMD EPYC
The Lenovo ThinkSystem SR675 V3 is a 3U GPU-dense rack server. It takes up to two AMD EPYC 9005 or 9004 Series processors with up to 160 cores each and 24 DDR5 DIMM slots for up to 3 TB of memory.
Three Base Configurations
Lenovo builds the SR675 V3 as a 4-DW model with up to 4 double-wide or single-wide PCIe GPUs, an 8-DW model with up to 8 double-wide or single-wide PCIe GPUs, or an SXM5 model with 4 x NVIDIA SXM5 GPUs and Lenovo Neptune liquid-to-air cooling, giving one platform for AI training, inference, HPC and visualisation.
Managed by Lenovo XClarity
Every SR675 V3 includes the XClarity Controller 2 (XCC2) for out-of-band management, TPM 2.0, a chassis intrusion switch and hot-swap drives and power supplies.

How to Configure Your Server — Sizing Checklist
Servers are built to order. Answer the questions below so we can size the right configuration for you.
Step 1: Hardware Requirements
- Which server form factor do you need: tower or rackmount?
- How many CPU cores, how much RAM and how much usable storage capacity do you require?
- How many processors: single-socket (1S), dual-socket (2S) or four-socket (4S)?
- Which RAID configuration do you need? Any specific HDD or SSD type, such as 7.2K or 10K rpm drives?
- Which network interface is required: 1GbE Base-T, SFP+ or Fibre Channel?
- How many years of maintenance support do you need? (Minimum 3 years)
Step 2: Deployment & Services
- How many server units are required?
- Will you run virtual machine workloads? Do you need a VMware licence, or Windows Server with Hyper-V?
- How do you store data today? Do you have existing NAS or SAN storage?
- How do you back up today? Would you like a backup proposal, such as an IDPA 8TB appliance?
- Do you require burn-in test services?
- Do you need hard disk retention services?

Frequently Asked Questions — Lenovo ThinkSystem SR675 V3
Is this a fixed configuration?
No. The SR675 V3 is configure-to-order. The base model, processors, memory, GPUs, drives, network adapters and support term are specified to your workload; use the sizing checklist above to brief us.
How many GPUs does it take?
Up to eight double-wide or single-wide PCIe GPUs in the 8-DW model, up to four in the 4-DW model, or four NVIDIA SXM5 GPUs in the SXM5 model.
Which processors does it use?
Up to two AMD EPYC 9005 or 9004 Series processors, with up to 160 cores per processor and TDPs up to 400 W.
How much memory can it take?
24 DDR5 DIMM slots for up to 3 TB, at up to 6400 MHz with EPYC 9005 processors.
Does the SXM5 model need a water supply?
No. The SXM5 model uses Lenovo Neptune liquid-to-air cooling, a closed loop inside the server, so it runs in an air-cooled rack.
