Lenovo Thinksystem SR650 V2 4310 32GB - 7Z73A06JNA

Lenovo 7Z73A06JNA ThinkSystem SR650 V2 2U Rack Server

Overview

The Lenovo ThinkSystem SR650 V2 (part number 7Z73A06JNA) is a 2U dual-socket rack server built around a single Intel Xeon Silver 4310 12-core processor with 32GB of DDR4 memory — a well-balanced starting point for virtualization hosts, video management system backends, and general enterprise workloads that need room to grow. The SR650 V2 represents a generational step forward from the original SR650, trading PCIe 3.0 for PCIe 4.0 slots and nearly doubling the GPU headroom — changes that matter if your workload roadmap includes AI inference, NVMe-over-Fabric storage, or GPU-accelerated video analytics at scale. The 7Z73A06JNA machine type (7Z73) ships with a 3-year warranty, which differentiates it from the 7Z72 machine type line that carries only a 1-year term.

Key Features

• Intel Xeon Silver 4310 (12-core, 2.1 GHz, 120W): Twelve cores with Ice Lake microarchitecture means solid multi-threaded performance for VMS recording servers, hypervisors, or database backends without the power overhead of a Gold or Platinum SKU. The platform supports second-socket expansion up to 40 cores and 3.6 GHz if your workload scales beyond a single processor.
• PCIe 4.0 — up to 8 slots: PCIe 4.0 doubles the per-lane bandwidth of Gen 3, which is the practical difference between a Gen 3 NVMe RAID bottleneck and genuinely saturating high-throughput storage. If you're running a video analytics server pulling from many simultaneous camera streams, Gen 4 I/O headroom is where that matters. The 1x internal bay for a cabled RAID/HBA card keeps your external PCIe slots open for NICs or GPU expansion.
• Up to 8x NVIDIA T4 GPU support: The SR650 V2 nearly doubles GPU density versus its predecessor (5x T4 max on SR650 → 8x T4 max on SR650 V2), and supports up to 3 double-wide GPUs. If you're planning to run on-server AI inference for video analytics or deep-learning workloads, that headroom means fewer chassis per rack to achieve your target throughput.
• 32GB starting memory, expandable to 8TB: The 32GB DDR4 configuration in this SKU is workable for a lightly loaded VM host or dedicated application server, but the platform scales to 8TB via 32x 256GB 3DS RDIMMs — or up to 12TB when you add Intel Optane Persistent Memory 200 Series. That ceiling is relevant for in-memory database, SAP HANA, or very large VMS index workloads.
• Intel Optane Persistent Memory 200 Series support: Up to 16 Pmem modules (8 per processor) can occupy DIMM slots alongside standard RDIMMs, pushing addressable memory to 12TB. Pmem is particularly effective for workloads where database restart latency matters — warm data survives a power cycle. Requires the second processor to be populated to reach the 16-module maximum.
• Memory protection (ECC, SDDC, ADDDC, mirroring): ECC is table stakes for any server; SDDC handles x4-based DIMM corrections at the chip level. ADDDC (requires Platinum or Gold processor) enables adaptive double-device data correction without the full cost of memory mirroring. For surveillance NVR applications where a single silent memory error can corrupt a recording index, these protection tiers matter.
• Hot-swap drives, PSUs, and fans: All three hot-swap subsystems are supported — meaning a drive failure, fan failure, or PSU failure can be remediated without taking the server offline. For a 24/7 video recording application, this is the difference between a 15-minute swap and a scheduled maintenance window.
• 3-year warranty (machine type 7Z73): The 7Z73 machine type carries a 3-year customer-replaceable unit and onsite limited warranty with 9x5 next business day response. The 7Z72 line carries only 1 year. Confirm your machine type before procurement if warranty term drives your total cost of ownership calculation.
• 2U, 445 × 87 × 764 mm (17.5 × 3.4 × 30.1 in.), max 85.5 lb: Standard 2U depth at 764mm (30.1 inches) fits most mid-depth and full-depth racks without a shelf extension. At a maximum populated weight of 85.5 lb, verify your rack's shelf or rail weight rating before fully populating drives and GPUs.

Integration and Compatibility

The SR650 V2 supports Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi — covering the full range of enterprise hypervisors and OS stacks used in security and enterprise IT environments. The onboard Intel I350 quad-port 1GbE NIC handles standard management and data traffic; higher-throughput OCP 3.0 NICs can be added via the OCP slot for 10/25GbE uplinks to core switches. XClarity Controller (XCC) provides out-of-band management for remote deployment, firmware updates, and hardware monitoring without requiring OS access — standard for rack servers managed via a rack server infrastructure framework. The integrated G200 graphics controller (16MB, max 1920×1200) is adequate for BIOS configuration and console access but is not intended for GPU compute workloads. For Lenovo server solutions, the SR650 V2 sits at the mainstream 2U dual-socket tier, positioned above the SR630 V2 (1U) and below purpose-built high-GPU platforms. Pair with a managed network switch sized for your camera or storage bandwidth requirements, and consult your NVR or VMS platform vendor for specific hardware compatibility matrices before finalizing storage and GPU configurations.

Frequently Asked Questions

Q: What is the warranty on the Lenovo 7Z73A06JNA?

A: The 7Z73A06JNA uses machine type 7Z73, which carries a 3-year customer-replaceable unit and onsite limited warranty with 9x5 next business day response. The 7Z72 machine type line carries only a 1-year warranty — confirm machine type before ordering if warranty term matters to your TCO.

Q: How many processors does the 7Z73A06JNA support?

A: The SR650 V2 supports one or two third-generation Intel Xeon Scalable (Ice Lake) processors. This SKU ships with a single Xeon Silver 4310 (12-core, 2.1 GHz, 120W). A second processor can be added to scale up to 40 total cores and unlock the full 16-module Intel Optane Persistent Memory capacity.

Q: What is the maximum RAM in the Lenovo SR650 V2?

A: With standard RDIMMs, the SR650 V2 supports up to 8TB using 32x 256GB 3DS RDIMMs. With Intel Optane Persistent Memory 200 Series added alongside RDIMMs, the total addressable memory reaches up to 12TB (16x 256GB 3DS RDIMMs + 16x 512GB Pmem modules).

Q: How many GPUs does the SR650 V2 support compared to the original SR650?

A: The SR650 V2 supports up to 8x NVIDIA T4 GPUs or up to 3x double-wide GPUs — nearly double the T4 capacity of the original SR650 (max 5x T4, 2x double-wide). This expanded GPU headroom is a key reason to choose V2 over the previous generation for AI inference or GPU-accelerated workloads.

Q: Does the SR650 V2 support PCIe 4.0?

A: Supported operating systems include Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi. Specific version support details are available in Lenovo's official OS compatibility documentation.

James Everett

The 7Z73A06JNA is the configuration I'd spec for a mid-scale VMS recording server or a VM host anchoring a physical security infrastructure — the Xeon Silver 4310's 12 cores handle concurrent recording and analytics processing without the cost premium of a Gold-tier processor, and the 3-year onsite warranty on the 7Z73 machine type removes a meaningful operational risk for 24/7 deployments where NBD field response matters.

Technical Highlights:

• PCIe 4.0 (up to 8 slots): Gen 4 bandwidth doubles per-lane throughput versus the original SR650's Gen 3 — directly relevant when pairing this chassis with high-speed NVMe RAID arrays for video storage, where Gen 3 I/O can become the bottleneck before the drives do.
• GPU expandability (up to 8x T4 or 3x double-wide): The SR650 V2 supports nearly double the GPU count of its predecessor. For deployments running on-server video analytics or AI inference — license plate recognition, object detection, forensic search — this headroom means you can scale within a single 2U chassis rather than adding another server.
• Memory protection tiers (ECC, SDDC, ADDDC, mirroring): ADDDC — available with Gold or Platinum processor upgrades — provides adaptive double-device data correction that ECC alone won't catch. For a recording server where a silent memory error can silently corrupt a video index, understanding which protection tier your processor SKU unlocks is worth a spec check before final BOM sign-off.

Deployment Considerations:

• At a maximum populated weight of 85.5 lb (38.8 kg) and a depth of 764mm (30.1 in.), verify your rack rail kit and shelf rating before fully loading this chassis with drives, dual PSUs, and GPU cards — overloaded rails are a common field oversight on dense 2U builds.
• ADDDC memory protection requires a Platinum or Gold processor. The Silver 4310 in this SKU supports ECC and SDDC only. If your application demands ADDDC (large in-memory databases, high-availability VMS), plan for a processor upgrade at configuration time — it cannot be patched in after the fact without a full CPU swap.

This configuration is a strong fit for a dedicated Milestone XProtect or Genetec Security Center recording server in a mid-size enterprise deployment — enough cores and I/O bandwidth for 50–100 camera streams, a 3-year warranty aligned to typical infrastructure refresh cycles, and PCIe 4.0 headroom to accommodate next-generation storage or analytics cards without a chassis replacement.
