Lenovo ThinkSystem SR655 V3

Example Use Cases:

  • AI inference — Strong fit because the SR655 V3 supports one 4th/5th Gen AMD EPYC CPU with up to 160 cores, PCIe 5.0, up to 3TB of DDR5 memory, and GPU support up to 3 double-width or 8 single-width GPUs.

  • Virtual Desktop Infrastructure (VDI) — Well suited for dense virtual desktop hosting because it combines very high core counts, 12 memory channels with DDR5 up to 6400 MHz, and flexible networking via OCP 3.0 plus additional PCIe network adapters.

  • OLTP databases — A good transactional database platform thanks to high per-socket compute density, support for fast NVMe storage, RAID/HBA options, and PCIe 5.0 I/O for low-latency data paths.

  • Analytics — Strong for in-memory and data-intensive analytics workloads because it offers up to 3TB of memory, high DDR5 bandwidth, and flexible internal storage with large NVMe-capable drive configurations.

  • Software-defined storage — Especially compelling here because the chassis is highly configurable, supporting up to 40x 2.5-inch or 20x 3.5-inch drives, combinations of SAS/SATA/NVMe/AnyBay, onboard NVMe, and multiple PCIe expansion options.
