Lenovo 7XG7A04628 SN550 Xeon 6130 16C/125W/2.1GHZ

Lenovo 7XG7A04628 Xeon Gold 6130 16-Core Processor Upgrade for SN550

Overview

The Lenovo 7XG7A04628 is a 1st Generation Intel Xeon Scalable Gold 6130 processor option for the ThinkSystem SN550 blade server — a 16-core, 32-thread CPU built for virtualization-dense and compute-heavy enterprise workloads where core count and memory bandwidth matter more than raw single-thread speed. Manufactured on Intel's 14nm Skylake process, this processor delivers a 2.1GHz base clock with a 3.7GHz Turbo Boost ceiling and a 125W TDP, fitting within the SN550's blade power envelope without requiring chassis-level power upgrades in standard configurations.

If you're expanding an existing Lenovo ThinkSystem SN550 deployment or populating a second processor socket on a blade that shipped with a single CPU, the 7XG7A04628 is the factory-sourced path to doubling core density without a platform change.

Key Features

• 16 Cores / 32 Threads (Skylake, 14nm): At 16 physical cores and 32 logical threads via Hyper-Threading, this processor handles dense VM stacks and parallel workloads that overwhelm 8- or 10-core predecessors. For a VMware or Hyper-V deployment running 20–40 guest VMs per blade, the additional threads directly translate to reduced CPU-ready wait times and better guest responsiveness under load.
• 2.1GHz Base / 3.7GHz Turbo Boost: The 2.1GHz base keeps sustained thermal load predictable within the blade chassis, while the 3.7GHz boost ceiling handles bursty single-threaded work — useful when VMs spike during backup windows or database query peaks without sustained thermal throttling.
• 125W TDP: At 125W, this falls within the standard SN550 blade power budget. Confirm chassis and power supply headroom before pairing with a second high-TDP processor in a dual-socket blade configuration — total blade draw approaches 250W at processor TDP alone, not accounting for memory, NVMe, or I/O.
• 22MB L3 Cache: The 22MB last-level cache reduces main memory round-trips on latency-sensitive workloads — database query engines and in-memory analytics platforms in particular benefit from the larger on-die cache compared to lower-tier Xeon SKUs with 14–16MB L3.
• 768GB Maximum Memory Support: The Gold 6130 supports up to 768GB of DDR4 ECC RAM per processor — critical for memory-intensive enterprise applications like SAP HANA, large Oracle instances, or VDI infrastructure where running out of memory forces expensive swap activity. In a dual-socket SN550 blade, the platform's total addressable memory scales accordingly.
• DDR4-2666 Memory Support: DDR4-2666 is the highest validated speed tier for this processor generation. Populating slots with 2666MHz RDIMMs maximizes memory bandwidth — relevant for workloads that are memory-bandwidth-bound rather than compute-bound, such as genomics pipelines or large in-memory caches.
• LGA 3647 (Socket P): The Socket P interface is the standard socket for 1st and 2nd Gen Intel Xeon Scalable across the ThinkSystem SN550 and related platforms. This matters for procurement teams managing mixed-generation blade inventories — confirm the blade's BIOS and firmware revision supports the Gold 6130 before installation, as early SN550 firmware revisions may require an update to correctly identify and initialize Skylake Gold-tier processors.
• 64-bit Operating Mode: Full 64-bit instruction support is expected at this tier, but it is worth noting for workloads migrating from legacy 32-bit environments — every guest OS and application can run natively without PAE or compatibility layers.

Integration and Compatibility

The 7XG7A04628 is a factory-configured processor option for the Lenovo ThinkSystem SN550 blade server platform. The SN550 uses the Scalable System Interconnect (SSI) blade form factor and operates within Flex System and NeXtScale chassis environments. Verify chassis compatibility and processor support matrix against the SN550's official Hardware Maintenance Manual before installation.

For data center networking and storage integrations, the Gold 6130's PCIe lane allocation and memory controller are relevant to I/O planning — consult the SN550 platform guide for lane budgeting when pairing with high-throughput NVMe or 25GbE adapters. Organizations running network video recorders or compute-intensive video analytics workloads on blade infrastructure should account for the 125W TDP when calculating per-chassis thermal and power draw across fully populated blades.

Memory compatibility: DDR4 RDIMMs and LRDIMMs at 2133, 2400, or 2666MHz are supported depending on DIMM population rules. Running all slots populated at maximum capacity may require stepping down to 2400MHz depending on DIMM configuration — check Lenovo's memory configurator for the SN550 to confirm validated DIMM combinations at target capacity and speed.

Frequently Asked Questions

Q: Which server platform is the Lenovo 7XG7A04628 designed for?

A: The 7XG7A04628 is a processor upgrade option for the Lenovo ThinkSystem SN550 blade server. It uses the LGA 3647 (Socket P) interface common to 1st Generation Intel Xeon Scalable platforms.

Q: How many cores and threads does the Xeon Gold 6130 provide?

A: The Gold 6130 delivers 16 physical cores and 32 logical threads via Intel Hyper-Threading Technology, operating at a 2.1GHz base frequency with a 3.7GHz Turbo Boost ceiling.

Q: What is the TDP of the 7XG7A04628, and does it fit within the SN550 blade power budget?

A: The Gold 6130 has a 125W Thermal Design Power rating. This falls within the SN550's standard blade power envelope for single-processor configurations. Dual-socket deployments should verify chassis and power supply capacity for sustained full-load operation.

Q: What is the maximum memory this processor supports?

A: The Gold 6130 supports up to 768GB of DDR4 ECC memory per processor socket, with DDR4-2666 as the top validated speed. Actual maximum capacity in the SN550 depends on blade slot count and DIMM population rules.

Q: Is the Gold 6130 (Skylake) compatible with 2nd Generation Intel Xeon Scalable (Cascade Lake) platforms?

A: The Gold 6130 is a 1st Generation Xeon Scalable (Skylake) processor. While both generations share the LGA 3647 socket physically, cross-generation compatibility in blade platforms is platform- and firmware-specific. Verify with Lenovo's SN550 processor support documentation before mixing generations in a chassis.

Q: What is the processor cache on the Gold 6130?

A: The Gold 6130 includes a 22MB L3 cache, which reduces main memory latency for cache-resident working sets — relevant for database engines and in-memory analytics workloads.

The 7XG7A04628 is a specific ask — you're either populating a second socket on an SN550 blade or replacing a failed CPU, and the 125W TDP of the Gold 6130 is the number that determines whether you can do it without touching chassis power infrastructure. At 16 cores and 32 threads on the Skylake microarchitecture, this processor fits the SN550's design envelope and gives you the core density to run meaningful VM consolidation ratios on a single blade.

Technical Highlights:

• 16C/32T at 125W: The core-to-TDP ratio here is reasonable for blade infrastructure — 7.8W per core at base TDP. That keeps per-chassis thermal load predictable when scaling from 4 to 8 blades in a fully populated chassis, which matters if you're working against a fixed facility cooling budget.
• 3.7GHz Turbo Boost ceiling: The 1.6GHz delta between base (2.1GHz) and boost (3.7GHz) is wide enough to handle bursty single-threaded work without sustained throttling — relevant for virtualization environments where a handful of VMs spike simultaneously during scheduled tasks like backups or patch windows.
• 768GB max DDR4-2666 per socket: This is the practical upper bound for memory-intensive workloads on the SN550. If your workload demands are pushing past 512GB addressable per blade, this CPU generation supports it — but confirm DIMM slot count on your specific SN550 configuration against the 768GB ceiling before purchasing DIMMs.

Deployment Considerations:

• Verify SN550 BIOS/firmware revision before installation. Early firmware builds for the SN550 may require an update to fully support Gold 6130 processor initialization and power management states — an update missed pre-install can cause unexpected POST behavior.
• At 125W TDP per processor, a dual-socket SN550 blade under full load will draw substantially more than 250W from the chassis midplane when memory and storage I/O are factored in. Audit chassis and PDU capacity before populating all blades in a high-density deployment.

The 7XG7A04628 is the right call for SN550 deployments adding a second processor to an existing single-socket blade — particularly in virtualization environments consolidating workloads from older dual-socket rack servers where a direct blade-based replacement with equivalent or better core count is the operational objective.
