HPE Intel Xeon-Silver 8-Core 2.1 GHz Processor

The 879595-L21 is HPE’s FIO (Factory Installed Option) kit designation for the Intel Xeon-Silver 4110 processor optimized for HPE ProLiant and XL series Gen10 platforms. It packages the Intel Xeon Silver 4110 single-socket server CPU configuration — an 8-core, 16-thread part with an 11 MB L3 cache and a nominal base clock of 2.10 GHz designed for mainstream two-socket server deployments where balanced core density, energy efficiency, and modern platform features are required.  

Key Specifications & Platform Details

Processor core, thread and clock profile

The Xeon-Silver 4110 delivers 8 physical cores and 16 logical threads via Hyper-Threading. Its published base frequency is 2.10 GHz with a maximum turbo single-core boost up to 3.00 GHz under Intel Turbo Boost 2.0, making it suitable for a mix of parallel and lightly threaded workloads. These characteristics give system architects predictable per-core performance while keeping platform thermal envelope moderate at 85 W TDP. 

Cache, memory and interconnect

The processor includes 11 MB of shared L3 cache and supports DDR4 memory technologies at industry standard speeds used on Gen10 HPE systems. The chip supports UPI (Ultra Path Interconnect) links for multi-socket coherence and offers a substantial number of PCIe lanes for I/O expansion, helping bridge compute and storage subsystems in rack servers.  

Socket, lithography and launch

The Xeon-Silver 4110 is built on Intel’s Skylake-based Xeon Scalable family and uses the LGA3647 (FCLGA3647) socket, typical of first-generation Skylake-SP server processors. It was launched in Q3 2017 and fabricated on a 14 nm process — details that are useful when assessing firmware, BIOS compatibility, and upgrade paths on older Gen10 server platforms.  

Use Cases

Balanced density for virtualization and general server workloads

The Silver 4110 offers an attractive balance of core count and single-thread speed, making it a common choice for virtualization hosts (light to medium consolidation ratios), application servers, web servers, and database front ends where per-core latency matters alongside multi-thread throughput. Its 85 W TDP provides improved power efficiency over higher-tier parts without sacrificing the ability to handle bursty, single-threaded peaks through turbo capability.

Cloud edge and scale-out infrastructure

For scale-out cloud architectures and edge computing where cost and power are constraints, the 4110 provides a stable baseline: reliable multi-core throughput, modern instruction-set extensions (AVX2, AES-NI), and the platform features required for enterprise virtualization stacks, containerized workloads, and distributed storage engines.

Compatibility & HPE Platform Fit

Supported HPE models & firmware considerations

The 879595-L21 appears in HPE ProLiant XL1x0r Gen10 parts lists and processor compatibility tables for Gen10 systems. When replacing or upgrading to this FIO kit, administrators must ensure BIOS/firmware revisions on HPE servers support the specific stepping and microcode of the Xeon-Silver 4110 — a common precaution with Skylake-SP era CPUs. HPE’s official server documentation and processor compatibility matrix remain the authoritative references for supported configurations.  

Socket & heatsink requirements

Because the CPU uses the LGA3647 physical interface, any upgrade or replacement requires a compatible socket and the server’s approved heatsink assembly rated for the 85 W TDP. HPE FIO kits typically include the processor only; some SKUs for factory installation may include mounting accessories. Always confirm whether the kit is intended for FIO installation by an authorized service provider or if field upgrades are supported for your server model.

Memory configuration guidance

For balanced memory bandwidth, populate memory channels according to HPE’s recommended DIMM population guidelines for the Gen10 system family. Matching DIMM sizes and operating speeds across channels helps maintain predictable NUMA behavior on two-socket systems and reduces memory latency variability for virtualization guests and databases.

Performance characteristics and tuning

Single-thread vs multi-thread behavior

The 2.10 GHz base clock with a 3.00 GHz turbo provides decent single-thread performance while the eight physical cores and Hyper-Threading expand concurrent thread capacity. For workloads that are latency-sensitive (single-threaded transactions or front-end request handlers), ensuring turbo frequencies can sustain short bursts (via adequate cooling and power budgeting) will show the most visible benefit.

BIOS power profiles and turbo

HPE servers expose BIOS/UEFI power and performance profiles that govern turbo behavior, C-state depth, and power management. For predictable low-latency service levels, choose performance or balanced profiles that restrict deep C-states and allow the CPU to reach/maintain turbo frequencies more quickly; for energy-savings, prefer dynamic/power-saving profiles. Test configurations under realistic load to determine the sweet spot between performance and power.

Memory bandwidth, I/O and expansion

With support for DDR4 and a healthy allotment of PCIe/UPI lanes typical of the Skylake-SP family, the 4110 can support NVMe storage tiers, network offload cards, and accelerator devices in typical HPE rack configurations. For I/O heavy workloads, plan PCIe lane allocation carefully and consider direct-attach NVMe versus shared SAN channels depending on workload locality and throughput needs.

Comparisons and upgrade paths

Within the Xeon Scalable family

Compared to higher tiers in the Scalable line (Gold or Platinum), the Silver family — including the 4110 — prioritizes efficiency and lower cost per core rather than maximum core count or larger caches. If workloads call for significantly higher single-thread or large cache sizes (in-memory databases, heavy analytics), stepping up to a Gold SKU or moving to newer generations may be warranted.

When to upgrade to a newer generation

Consider a generational upgrade when your workload demands more cores per socket, wider memory bandwidth (DDR5 in newer platforms), PCIe 4.0/5.0 lanes, or specialized accelerators. If your environment relies on specific new instructions or accelerators (e.g., DPUs, later generation AVX improvements), assess roadmap timelines and total migration cost before committing to a hardware refresh.

Virtualization and Enterprise Features

Hardware security and virtualization support

The Xeon-Silver 4110 supports Intel virtualization technologies and hardware-assisted security features typical of the Skylake-SP era, including Intel VT-x/VT-d for virtualization and AES-NI for encryption acceleration. These features make it suitable for multi-tenant virtualization stacks as long as the hypervisor is kept current and platform firmware supports virtualization offloads.

Firmware and microcode patching responsibilities

Security vulnerabilities addressed via microcode updates are part of routine platform maintenance. For production environments, integrate microcode updates into your maintenance windows and test patches in a staging environment to detect potential regressions — especially when running hypervisors or containers sensitive to instruction set timing changes.

Recommended monitoring metrics

Track CPU package temperature, per-core frequency, power draw, memory errors (ECC events), and platform event logs (SEL/iLO) during initial deployment and periodically after upgrades. Monitoring will highlight whether thermal throttling or microcode interactions are affecting target SLAs.

Replacement parts & cross-reference section

Alternate HPE SKUs and Intel tray numbers

When building an internal parts cross-reference, map HPE’s 879595-L21 to Intel’s processor family number (4110) and common tray spec codes used by suppliers (e.g., SR3GH/SR3G variants on aftermarket listings). Maintaining an up-to-date cross reference reduces procurement errors and ensures correct firmware pairing.

Where to source

Source from HPE channels for factory installed kits to preserve support. For cost savings, trusted secondary market suppliers and refurbishers list tray or tested pulls of the Intel Xeon Silver 4110; validate seller test procedures, warranty terms, and return policies prior to purchase.
