Lenovo Thinksystem SR650 V2 4309Y 32GB - 7Z73A06HNA

Lenovo 7Z73A06HNA ThinkSystem SR650 V2 2U Rack Server

Overview

The Lenovo ThinkSystem SR650 V2, model 7Z73A06HNA, is a 2U rack server built around third-generation Intel Xeon Scalable processors (Ice Lake) and the Intel C621A chipset. It ships configured with a 4309Y processor and 32GB of memory, making it a practical starting point for enterprise workloads that will scale over time. The SR650 V2 is a direct replacement for the SR650 V1 in deployments requiring higher PCIe bandwidth — the jump from PCIe 3.0 to PCIe 4.0 doubles per-slot throughput, which matters in GPU-intensive or high-IOPS NVMe storage configurations. This machine type (7Z73) includes a three-year limited warranty with 9x5 next-business-day onsite coverage, versus the one-year warranty on 7Z72 configurations.

Compatibility

The 7Z73A06HNA is part of the Lenovo ThinkSystem SR650 V2 server family. It supports one or two third-generation Intel Xeon Scalable processors up to 40 cores, up to 3.6 GHz, and 270W TDP — any Ice Lake Xeon Scalable CPU within those bounds can be installed in a second socket to scale compute. Memory expansion supports up to 32x DIMM slots: up to 8TB using 256GB 3DS RDIMMs, or up to 12TB in configurations that combine 3DS RDIMMs with Intel Optane Persistent Memory 200 Series modules (up to 16x Pmem modules, 8 per processor). The server accommodates up to 8x PCIe 4.0 slots plus one dedicated internal bay for cabled RAID or HBA cards. GPU configurations support up to 8x NVIDIA T4 GPUs or up to 3x double-wide GPU cards — relevant for AI inference or video analytics workloads running alongside VMS platforms. Supported operating systems include Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi.

Installation Notes

The 7Z73A06HNA occupies 2U of rack space at 445 mm wide × 87 mm tall × 764 mm deep (17.5 × 3.4 × 30.1 in.) — confirm rack depth clearance at 30+ inches before ordering. Drives, power supplies, and fans are all hot-swap capable, reducing planned maintenance windows. No internal optical or tape drive bays are present; OS deployment requires network boot or external media. The integrated XClarity Controller provides remote management via a G200 graphics core (up to 1920×1200 resolution), enabling out-of-band access without a dedicated GPU for console use. Memory protection includes ECC, SDDC, and ADDDC (Platinum/Gold processors required for ADDDC), plus memory mirroring — relevant for workloads where DRAM errors carry operational cost.
