The Lenovo ThinkSystem SR630 V4 is a 1U dual-socket-capable rack server on Intel's Xeon 6 platform. This particular listing specifies a single Intel Xeon 6517P (16-core) processor with 64GB of RAM -- a minimal, entry-level configuration within the SR630 V4 family, likely intended as a lower-cost starting point that can be expanded with a second CPU and additional memory later, or for a workload that genuinely doesn't need more compute or memory than this. Even at this smaller configuration it retains the Xeon 6 platform's current-generation DDR5 memory and PCIe Gen5 expansion capability.
