Enterprise-Class Performance for Edge and Branch Offices
The ST250 V3 is optimised for small-to-medium businesses and remote installations requiring reliable, manageable server infrastructure. With support for up to 128GB of DDR5 memory, PCIe Gen5 technology, and the latest Intel Xeon E-2400 series processors, this server handles demanding workloads including virtualisation, file and print services, database applications, and edge computing with ease. The 8-core Xeon E-2478 processor delivers exceptional multithreading performance for business-critical applications.
Flexible Storage and Expansion
This configuration includes 8 × 2.5-inch hot-swap drive bays with onboard SATA controller and software RAID support, allowing you to configure storage to meet your specific needs. The server also features two 5.25-inch media bays for optional optical or RDX tape drives, plus support for dual M.2 drives for OS boot redundancy. Four PCIe slots provide room for RAID controllers, network adapters, or graphics cards.
Integrated Systems Management
The ST250 V3 includes Lenovo XClarity Controller 2 (XCC2) for comprehensive out-of-band systems management, monitoring, and firmware updates. A dedicated Gigabit Ethernet management port ensures reliable remote access without impacting production network traffic. The server supports integration with Lenovo XClarity Administrator for centralized management of multiple ThinkSystem servers across your infrastructure.
Connectivity and Ports
Front:
- 1 × USB 3.2 Gen1 (5Gb/s) port
- 1 × USB 2.0 port (XClarity Mobile connectivity)
Rear:
- 4 × USB 3.2 Gen1 (5Gb/s) ports
- 1 × VGA video port
- 2 × RJ-45 Gigabit Ethernet ports (Broadcom BCM5720)
- 1 × RJ-45 systems management port (XCC2)
- 1 × Serial port
Internal:
- 1 × USB 3.0 port for RDX drive
Tower or Rack Deployment
The ST250 V3 ships as a tower server but can be converted to a 4U rack-mount configuration with the optional Rack Mount Kit, providing deployment flexibility for diverse IT environments. The compact footprint (176mm W × 444mm H × 578mm D) makes it ideal for space-constrained remote offices and branch locations.
Security Features
-
TPM 2.0 (Trusted Platform Module) for hardware-based security
-
Intel Boot Guard for secure boot verification
-
Root of Trust module with integrated Platform Firmware Resiliency
- Optional front lockable bezel
- Optional chassis intrusion switch
Power and Cooling
Equipped with a single 800W hot-swap power supply (second bay available for optional redundancy), the ST250 V3 delivers reliable power for demanding configurations. The server supports ASHRAE A2 environments, making it suitable for installations with less controlled ambient temperatures.
