- NVIDIA RTX 6000 Ada
AMD Instinct MI210 is also supported. Depending on configuration, the server can support up to 8 single-width GPUs or 3 double-width GPUs.
This makes the SR650 V3 suitable for:
- Artificial intelligence
- Machine learning
- Deep learning
- GPU-accelerated analytics
- Scientific computing
- Rendering
- Video processing
- HPC
High-Speed Networking
Networking is provided through the server’s OCP 3.0 slot, with two- or four-port Ethernet adapters available depending on configuration. PCIe networking adapters can also be installed for additional connectivity.
The platform can therefore be configured for high-speed enterprise networks, storage networks, and cluster environments.
Lenovo XClarity Controller 2
The SR650 V3 incorporates Lenovo XClarity Controller 2 (XCC2) for server monitoring and remote management.
XCC2 provides capabilities such as:
- Remote hardware management
- System monitoring
- Remote KVM
- Remote media
- Hardware diagnostics
- Health monitoring
- Alerting
- Firmware management
This simplifies administration of servers deployed in enterprise data centers.
Redundant Power and Cooling
The server supports up to two hot-swap power supplies, allowing redundant power configurations.
Available PSU options include 750W, 1100W, 1800W, 2400W, and 2600W models, depending on configuration and input requirements.
The server also supports redundant hot-swap cooling fans, helping maintain reliable operation in demanding data-center environments.
