Lenovo 7Z74A02JNA ThinkSystem ST650 V2 Tower Server

Overview

The Lenovo ThinkSystem ST650 V2, model 7Z74A02JNA, is a 4U tower-convertible-to-rack server built for compute-intensive workloads including video analytics, AI inference at the edge, and enterprise surveillance back-end processing. Where its predecessor (the ST550) topped out at 1GbE embedded networking and two GPU slots, the ST650 V2 steps up to dual 10GBASE-T embedded ports and support for up to four double-wide or eight single-wide GPUs — making it a practical fit for on-premises NVR and VMS deployments that need GPU-accelerated analytics running alongside high-throughput camera ingestion. Machine type 7Z74 carries a 3-year warranty; the functionally identical 7Z75 ships with one year.

Compatibility

The 7Z74A02JNA accepts one or two third-generation Intel Xeon Scalable processors (Ice Lake), supporting up to 36 cores per socket at up to 3.6 GHz and TDPs to 250W. Memory slots support up to 32x RDIMMs for a 4TB ceiling using 128GB 3DS RDIMMs, or a 5TB configuration mixing 3DS RDIMMs with Intel Optane Persistent Memory 200 Series modules (16 Pmem slots, 8 per processor). Memory protection includes ECC, SDDC, ADDDC (Platinum or Gold processors required for ADDDC), and mirroring. The two onboard 10GBASE-T RJ45 ports run on a Broadcom BCM57416 controller — adequate throughput for aggregating streams from large camera counts or feeding a downstream NVR array. A dedicated 1GbE management port connects to the XClarity Controller for out-of-band administration. GPU expansion targets workloads pairing Lenovo tower servers with inference accelerators; up to 8x single-wide or 4x double-wide GPU adapters are supported, a 4x improvement over the ST550 in double-wide capacity.

Installation Notes

Physical footprint in tower orientation: 175 mm wide × 462 mm tall × 734 mm deep (6.9 × 18.2 × 28.9 in.). The chassis is rack-convertible — confirm rail kit compatibility with your rack before deployment. Cooling is handled by up to four hot-swap 92 mm fans (single- or dual-rotor, N+1 redundant) plus one fan per power supply; fan configuration is load and thermal dependent. For rack-mount deployments, verify ceiling clearance and cable management before converting the chassis orientation. Consult the switching infrastructure supporting this server to confirm 10GbE uplink availability at the top-of-rack layer.
