Description

The ThinkSystem SR650 is a robust 2U rack server equipped with dual Intel Xeon Gold 6230 processors (20 cores / 40 threads each, 2.1 GHz base, 3.9 GHz turbo, 27.5 MB cache) delivering up to 40 physical cores and 80 threads for intensive compute environments 

With 256 GB of DDR4 ECC memory (RDIMM), this SR650 handles virtualization, databases, and analytics with ease, leveraging the platform’s support for up to 1.5 TB memory across 24 DIMMs.

Storage is provisioned via eight 1.2 TB 10K SAS 12 Gb/s HDDs, ideal for performance-tier RAID configurations supporting both capacity and speed. A hardware RAID controller ensures data resilience and high availability. Networking is handled by four 1 Gb RJ45 NICs—suitable for management, backup, and basic network throughput. The system runs on Windows Server 2022 Standard, a stable platform for enterprise services.

Key Features

  • Dual Intel Xeon Gold 6230 CPUs: 20 cores / 40 threads, 125 W TDP, PCIe Gen 3 support 
  • 256 GB DDR4 ECC RDIMM for high concurrency and stability
  • 8×1.2 TB 10K RPM SAS 12 Gb/s HDDs in Hot-Swap bays for RAID configurations
  • Hardware RAID controller with advanced caching
  • 4×1 GbE RJ45 NICs for network redundancy and management
  • Pre-installed Windows Server 2022 Standard—production-ready OS

Compatibility

The SR650 supports a wide variety of Lenovo ServerProven components including Intel Xeon Scalable CPUs, DDR4 RDIMM/LRDIMM memory, SAS/SATA/NVMe storage, and PCIe networking cards.

The Xeon 6230 CPUs pair with the C624 chipset and support PCIe 3.0, UPI interconnect, Intel Turbo Boost, Hyper‑Threading, and AVX‑512 acceleration.

Usage Scenarios

Ideal for virtualization (Hyper‑V), the server supports multiple VMs with ample CPU and memory resources. The 10K SAS drives and RAID ensure high-performance storage for databases, file services, and general-purpose line‑of‑business applications.

With Windows Server 2022 Standard, it’s ready for modern Windows-based workloads—Active Directory, IIS, file/print, or container hosting.

The redundant NICs support network segmentation (management, backup, data), and storage capacity is scalable via additional SATA/NVMe expansion if needed.
