Lenovo ThinkSystem SR645 1U rack server EPYC 7203 32GB DDR4 7D2X100DNA

ThinkSystem SR645 1U AMD EPYC 7203 server

The Lenovo ThinkSystem SR645 is a 1U rackmount server built for general-purpose workloads. It ships with a single AMD EPYC 7003 series 7203 processor running at 2.80 GHz with 8 cores and 64 MB L3 cache. The system includes 32GB of DDR4 memory and supports up to 8TB maximum capacity across 32 DIMM slots.

Compatibility checklist for your rack and storage

Verify that your rack provides 1U of space and sufficient airflow for six hot-swap performance fans. The chassis uses a SATA/SAS backplane for 2.5-inch drive bays; no drives are installed, so you must supply compatible SATA or SAS storage. Confirm your power infrastructure can deliver 1100W to the server's power supplies.

Suited for memory-heavy tasks not GPU-dependent

This configuration suits virtualisation hosts, database nodes or compute clusters that benefit from eight memory channels per processor and high DIMM counts. It is not for buyers who need GPU acceleration, as no GPU is included and the 1U form factor limits expansion. Organisations requiring dual-processor performance from day one should look at a two-socket configuration.
