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.

Questions sur cet article
Does the Lenovo ThinkSystem SR645 7D2X100DNA include any drives or do I need to buy SATA or SAS drives separately?
No drives are installed. The chassis provides open 2.5-inch bays that accept SATA or SAS drives, so you must purchase storage separately.
The spec sheet lists DDR4 RDIMMs and 3DS RDIMMs at different speeds. Which memory type should I choose for the 7203 processor?
With one EPYC 7203 installed you have 16 slots across 8 channels. Standard RDIMMs run at 3200 MHz with one per channel or 2933 MHz with two per channel; 3DS RDIMMs run slower. Pick RDIMMs for the highest speed.
The headline figure is 8 TB maximum memory. What does that mean for a single 8-core 7203 CPU?
The 8 TB limit requires two processors. With the single 7203 you can populate 16 DIMM slots; the practical ceiling depends on the highest-capacity DDR4 RDIMMs available.
