Lenovo 7Z74A01YNA ThinkSystem ST650 V2 Tower/Rack Server

Overview

The Lenovo ThinkSystem ST650 V2 (model number 7Z74A01YNA) is a 4U tower server with rack-conversion capability, built around third-generation Intel Xeon Scalable processors (Ice Lake). It ships in the 7Z74 machine type, which carries a 3-year manufacturer warranty — one tier above the 7Z75 series. Designed for enterprise workloads that require dense memory capacity, GPU compute, or both, the ST650 V2 fits demanding on-premises deployments including video analytics, AI inference, and surveillance back-end processing where a rackmount form factor is preferred but tower footprint is an option.

Compatibility

The ST650 V2 supports one or two third-generation Intel Xeon Scalable processors (formerly "Ice Lake"), with configurations up to 36 cores per socket, speeds up to 3.6 GHz, and TDPs up to 250W per CPU. The Intel C621A "Lewisburg" chipset (Whitley platform) underpins the memory subsystem, which scales to 4TB using 32x 128GB 3DS RDIMMs — relevant when running large in-memory video databases or analytics pipelines across many concurrent streams. GPU support reaches 4x double-wide (DW) or 8x single-wide (SW) adapters, twice and four times the capacity of the predecessor ST550 respectively, making the ST650 V2 compatible with multi-GPU inference workloads that a single-socket or previous-gen platform cannot host. Persistent memory via Intel Optane Persistent Memory 200 Series (up to 16 modules, 8 per processor) extends addressable capacity to 5TB in mixed DIMM+Pmem configurations. Network connectivity uses dual onboard 10GBASE-T RJ45 ports (Broadcom BCM57416) plus a dedicated 1GbE XClarity Controller management port — a step up from the ST550's embedded 1GbE data ports, supporting higher-throughput camera feeds or NVR data ingest without an add-in NIC.

Installation Notes

Cooling is handled by up to four hot-swap 92mm fans (single- or dual-rotor, configuration dependent) in an N+1 redundant arrangement, with one additional fan integrated per power supply. Rack conversion from tower orientation requires the appropriate rack-mount kit for the ST650 V2 chassis. Physical dimensions are 175mm wide × 462mm tall × 734mm deep (6.9 in. × 18.2 in. × 28.9 in.) — verify rack depth clearance before ordering rail hardware.
