Lenovo ThinkSystem SR655 Rackmount Server

Lenovo SR655 Information
The AMD EPYC 7002 “Rome” and AMD EPYC 7003 “Milan” processor families are used in the Lenovo ThinkSystem SR655, a 1-socket 2U server. The SR655 offers the maximum in single-socket server performance, with up to 64 cores per processor and compatibility for the PCIe 4.0 standard for I/O. With up to 128 PCIe lanes, the server is ideal for workloads that can take advantage of GPU processing and high-performance NVMe drives. The SR655 has been designed to take advantage of the features of the EPYC 7002 and 7003 processors, such as the full performance of 280W 64-core processors, support for 3200 MHz memory and PCIe Gen 4.0 support.
