Tower or rack-mountable server with one Intel Xeon E-2488 processor at 3.20 GHz and 16 GB DDR5 ECC memory, expandable to 128 GB
The Lenovo ThinkSystem ST250 V3 7DCEA01ZNA is a 4U tower or rack-mountable system equipped with one Intel Xeon E-2488 processor running at 3.20 GHz and 16 GB of DDR5 memory. It targets small businesses and remote offices that need a single-socket platform for file, print, virtualisation or light database workloads with room to grow memory and storage later.
The chassis accepts standard UDIMMs in four slots and supports up to 128 GB using 32 GB modules at 4400 MHz. Drive bays are tool-less for hot-swap configurations but simple-swap trays require screws; mixing bay types is not supported. GPU options are limited to NVIDIA Quadro T1000 or T400 cards, which need the x16 slot and adequate PSU headroom. The fixed 300 W or 500 W supply leaves limited power for multiple GPUs or dense NVMe installations.
Confirm that your rack kit matches the 4U height and that the chosen drive-bay variant aligns with your SAS, SATA or NVMe drives. Verify the operating system from the supported list — Windows Server, SUSE, Red Hat or VMware vSphere — and ensure the single-processor limit meets your licensing model. Check that the two 1 GbE LOM ports plus the dedicated management port satisfy your network topology before ordering.
