Lenovo-ThinkSystem SR650 V3

Description

The Lenovo ThinkSystem SR650 V3 is a versatile enterprise-class rack server engineered to deliver high compute performance, memory bandwidth, storage flexibility, and expansion capabilities for modern data-center environments.

Its 2U rack-mounted design provides an excellent balance between computing density, storage capacity, expandability, and serviceability. The platform is suitable for organizations requiring a scalable server for virtualization, databases, cloud infrastructure, analytics, AI, and other demanding workloads.

Powerful Intel Xeon Scalable Processors

The SR650 V3 supports one or two 4th Generation Intel Xeon Scalable processors or one or two 5th Generation Intel Xeon Scalable processors.

Depending on the selected processor, the platform supports up to 64 cores per CPU, with processor TDPs reaching up to 385W on supported configurations.

This processing architecture makes the SR650 V3 suitable for:

Enterprise virtualization
Database applications
ERP systems
Cloud computing
AI and machine learning
Data analytics
High-performance computing
Enterprise application hosting
Software-defined infrastructure

High-Speed DDR5 Memory

The SR650 V3 features 32 DDR5 DIMM slots in a two-processor configuration and supports Lenovo TruDDR5 RDIMM and 3DS RDIMM technology.

Supported memory speeds depend on the installed processor and DIMM configuration, with up to 5600 MT/s supported with compatible 5th Generation Intel Xeon processors. The platform can support up to 8TB of memory using supported 256GB 3DS RDIMMs.

High memory capacity is particularly valuable for:

Virtual machine consolidation
In-memory databases
Large datasets
Analytics
AI workloads
HPC applications
Memory-intensive enterprise software

Flexible Storage Architecture

The SR650 V3 offers extensive storage flexibility and can be configured with combinations of SAS, SATA, and NVMe drives.

Depending on the chassis and backplane configuration, it supports:

Up to 24 × 2.5-inch hot-swap SAS/SATA/NVMe drives
Up to 12 × 3.5-inch hot-swap SAS/SATA drives
Up to 4 × 3.5-inch NVMe drives
Additional middle and rear drive bays
Up to two internal M.2 drives
Optional 7mm hot-swap boot drives

The platform can therefore be configured for high-capacity storage, high-performance NVMe environments, or a combination of both.

NVMe and RAID Support

The server supports direct NVMe connectivity as well as storage configurations using Intel VROC and Lenovo ThinkSystem RAID/HBA adapters.

Onboard SATA software RAID supports RAID 0, 1, 5, and 10, while Intel VROC NVMe configurations provide additional NVMe RAID capabilities depending on the selected license and configuration.

This makes the SR650 V3 suitable for applications requiring both high storage performance and data protection.

Extensive PCIe Expansion

The SR650 V3 provides up to 12 PCIe expansion slots, using a combination of PCIe Gen4 and Gen5 interfaces depending on configuration.

It also includes an OCP 3.0 networking slot for flexible high-speed network connectivity.

Expansion options can include:

RAID controllers
Fibre Channel adapters
High-speed Ethernet adapters
Storage controllers
GPU accelerators
Specialized PCIe devices
Data-processing accelerators

Depending on the configuration, the server can support up to 8 single-width GPUs or 3 double-width GPUs.

GPU acceleration makes the SR650 V3 suitable for:

Artificial intelligence
Machine learning
Deep learning
Scientific computing
Data analytics
Rendering
Video processing
GPU-accelerated applications

High-Speed Networking

The SR650 V3 uses an OCP 3.0 networking interface and can also accommodate additional PCIe networking adapters.

This provides flexibility for enterprise Ethernet, high-speed storage networks, virtualization clusters, and specialized data-center environments.

Lenovo XClarity Controller 2

The SR650 V3 incorporates Lenovo XClarity Controller 2 (XCC2) for hardware monitoring and remote management.

Management functions include:

Remote server management
Hardware health monitoring
System diagnostics
Hardware inventory
Alerting
Firmware management
Remote troubleshooting

This enables IT administrators to efficiently manage server infrastructure from centralized management environments.

Enterprise Power and Cooling

The SR650 V3 supports up to two hot-swap power supplies, allowing redundant power configurations.

Available PSU options include 750W, 1100W, 1800W, 2400W, and 2600W models, with Platinum and Titanium efficiency options depending on configuration.

Hot-swap cooling fans provide redundancy for reliable operation in demanding data-center environments.

Enterprise Security

The SR650 V3 incorporates Lenovo enterprise security technologies, including ThinkShield and hardware-level security and management capabilities.

These technologies help organizations protect server infrastructure, firmware, configurations, and workloads throughout the server lifecycle.
