Lenovo SR655 | ThinkSystem 2U Rack Server, AMD EPYC 7002/7003, 64 Cores

Q: What processors does the SR655 support?
A: The SR655 supports AMD EPYC 7002 series (Rome) and AMD EPYC 7003 series (Milan) processors in a single-socket configuration, with up to 64 cores and 128 PCIe 4.0 lanes. It is designed to take full advantage of 280W 64-core processors.

Q: What storage configurations are available?
A: The SR655 offers flexible storage with support for up to 32x 2.5-inch or 20x 3.5-inch hot-swap drive bays depending on chassis configuration. It supports all SAS, all SATA, all NVMe, or mixed configurations, making it ideal for software-defined storage and high-performance NVMe workloads.

Q: Can the SR655 support GPU workloads?
A: Yes, the SR655 is a multi-GPU optimized server that supports up to 6 single-wide GPUs. With 128 PCIe 4.0 lanes available from the processor, it is well-suited for AI inference, VDI acceleration, and other GPU-accelerated workloads.

Q: What is the maximum memory capacity?
A: The SR655 supports up to 16 DDR4 memory DIMMs across 8 memory channels (2 DIMMs per channel). When populated with 128GB 3DS RDIMMs, the server can reach a maximum capacity of 2TB. Memory operates at up to 3200MHz with single DIMMs per channel or 2933MHz with dual DIMMs per channel.

Q: What makes the single-socket design advantageous?
A: The single-socket design delivers two-socket level performance while reducing software licensing costs for applications that use per-socket licensing models. With up to 64 cores and 128 PCIe lanes in one processor, it provides high core density and exceptional I/O throughput with lower latency compared to traditional dual-socket configurations.
