The 879731-B21 processor kit

The HPE kit is more than just a CPU — it is a tested, field-serviceable package that includes the processor and the HPE-approved heatsink and fan configuration needed for reliable operation in supported ProLiant servers. Buyers choosing a kit over a loose CPU benefit from:

Assured compatibility

HPE ships these kits validated for specific ProLiant Gen10 chassis, ensuring the mechanical, thermal and firmware interactions are pre-tested. This reduces surprise firmware incompatibilities and eliminates guesswork when building or refreshing a Gen10 rack node.

Optimized thermal profile

The included heatsink and fan bundle is tuned to the processor’s 85 W thermal design power. For multi-CPU configurations pay attention to the kit variant suffixes (L21/B21) — HPE documentation indicates different fan counts and placements depending on whether the kit is used as the first or second processor in the chassis. Proper cooling ensures stable boost behaviour and long-term reliability.

Serviceability & support

When you choose an HPE kit part number like 879731-B21, you’re buying into HPE replacement workflows and spares stocking. For enterprise deployments, that often shortens repair time and simplifies lifecycle management.

Technical deep dive

Architecture and microfeatures

The Xeon Silver 4110 belongs to the Intel® Xeon® Scalable family (formerly Skylake-based parts in the early scalable lineup). It supports modern server instruction sets and features that accelerate data handling, virtualization and secure compute:

• Intel® Hyper-Threading Technology for improved parallelism
• Intel® AES New Instructions (AES-NI) for hardware-accelerated cryptography
• Execute Disable Bit and Mode-Based Execute Control (MBE) for security hardening
• UPI links (two links typical) for multi-socket coherency in supported configurations

Memory and I/O considerations

The platform and processor pairing supports DDR4 memory in HPE specified DIMM populations — on Gen10 servers that means paying attention to whether you’re running first- or second-generation Scalable CPUs (memory speed rules differ). The Silver 4110 typically pairs with DDR4 modules at vendor-recommended speeds (see platform memory population guidance for exact supported frequencies and capacities).

PCIe lanes & expansion

Expect a robust complement of PCIe lanes suitable for NVMe storage adapters, high-bandwidth NICs, and storage controllers. The exact lane count available to end-user expansion depends on the server backplane and riser configuration, so consult the HPE ProLiant server quickspecs when planning I/O expansion.

Performance profile & common workloads

The Xeon Silver 4110 excels at balanced server workloads that require moderate core counts, consistent per-core performance and good multi-thread scaling. Typical use cases include:

• Virtualization hosts (small-to-medium density VM consolidation)
• Web and application servers where per-thread latency matters
• Database frontends and caching layers
• File & block storage controllers that combine CPU with local NVMe/HDD arrays
• Edge-of-network compute nodes with constrained power/thermal envelopes

Comparative notes

Compared to Bronze/entry Xeons, the Silver class brings higher base clocks, larger caches and SMT support. Against Gold/Platinum parts, Silver targets lower TCO and energy consumption while offering fewer cores per socket — making it optimal where licensing cost per core or thermal envelope are limiting factors.

Compatibility & server fits

HPE part numbers map to tested server assemblies. The 879731-B21 kit is most commonly specified for the ProLiant DL180 Gen10 family and similar Gen10 platforms. Important compatibility checks before purchase:

• Confirm your server model is listed in the HPE parts compatibility matrix for 879731-B21.
• When populating dual-CPU systems, use the correct paired kit variant (HPE notes different fan/heat sink counts for first vs second processor kits — L21 vs B21 suffixes).
• Match memory kit speed to the processor generation: mixing 1st and 2nd generation Xeon Scalable SKUs may require specific DDR4 speeds per HPE platform guidance.

Practical checklist before upgrading

1. Verify BIOS/firmware level — update server firmware to the recommended version for Xeon Scalable support.
2. Confirm heat sink and fan routing are correct for the kit variant being installed.
3. Ensure identical processor models are used in both sockets for dual-CPU configurations (mixing models is not supported).
4. Back up configuration and OS images; validate OS and hypervisor compatibility with the CPU microcode level.

Thermals, power & rack planning

With an 85 W TDP the Silver 4110 sits in the low-to-mid power band for Xeon scalable parts. Nonetheless, when deployed at scale you should:

• Plan rack power delivery with headroom for peak turbo draws; TDP is a planning metric, not a continuous power draw guarantee.
• Confirm adequate intake and exhaust airflow in short-depth and dense rack configurations.
• Monitor inlet temperatures and configure server thermal profiles per HPE guidance to avoid sustained thermal throttling.

Optimizing density vs. performance

If your deployment prioritizes core density (maximum cores per rack), consider higher-core Gold or Platinum SKUs — but if TCO, lower licensing costs or lower heat are priorities, the Silver 4110 often provides an efficient middle ground.

Related parts & accessories

Products commonly purchased alongside the 879731-B21 kit include:

• OEM HPE heatsinks and fan modules (verify exact HPE part numbers for DL180/DL360/DL380 Gen10 builds)
• HPE-qualified memory kits (matched DIMM kits to meet speed and channel population rules)
• High-performance NVMe PCIe adapters or HPE Smart Array controllers for storage acceleration
• Redundant power supplies sized for your fully populated rack nodes

Alternative SKUs & upgrade paths

If your workload needs more cores or higher single-thread throughput consider stepping up to Xeon Gold SKUs; for power-sensitive edge use, evaluate lower TDP Bronze parts. Conversely, if you need a similar thermo/power envelope but higher single-thread speed, review higher turbo frequency Silver or low-core Gold options. Always match server firmware and memory rules when changing SKU families.
