HPE 874655-B21 Intel ProLiant XL450 Gen10 Processor

The HPE 874655-B21 Intel ProLiant XL450 Gen10 Xeon-Gold 6134 3.2GHz 8-core 130W Processor category covers a focused class of enterprise compute components — high-performance, rack-optimized CPU modules designed for HPE ProLiant XL450 Gen10 servers. This category description explains capabilities, technical specifications, deployment scenarios, and buyer considerations to help IT purchasers, datacenter engineers, and systems integrators evaluate fit and plan upgrades. The content below unpacks the processor's core features, expected performance characteristics, power and thermal implications, memory and I/O compatibility, firmware and management integration, and real-world use cases such as virtualization, database workloads, and HPC burst compute.

Key characteristics of the Xeon-Gold 6134 offering in HPE XL450 Gen10

The Intel Xeon-Gold 6134 is a server-class processor targeted at mainstream to high-end enterprise workloads. In the HPE 874655-B21 configuration the CPU provides a blend of high single-thread clock speed and moderate core count, making it well-suited for applications that benefit from strong per-core performance while still offering multi-threading headroom. Typical category attributes include:

Detailed technical breakdown

Processor microarchitecture and performance benefits

The Xeon-Gold 6134 is built on a server microarchitecture that emphasizes instruction throughput and cache efficiency. For applications that rely on short, latency-sensitive transactions (web services, in-memory databases, application servers), the 3.2GHz clock and cache hierarchy reduce instruction latency. When used in multi-socket XL450 Gen10 configurations, the CPU’s interconnect and memory channels enable strong scaling for moderate parallel workloads.

Single-thread and multi-thread tradeoffs

This SKU delivers a favorable balance: higher base clock improves single-threaded tasks whereas the eight cores provide a sensible degree of parallelism for multi-tenant virtualization or container density. For workloads that are heavily vectorized or use AVX2 instructions, users should plan for increased power consumption during sustained AVX workloads due to frequency scaling behavior.

Cache, memory, and I/O considerations

Cache size and memory channel configuration are critical to real-world throughput. The category is often paired with high-speed DDR4 memory modules in HPE ProLiant servers; for optimal results, configure matched memory per HPE guidelines to maximize channel utilization. PCIe lanes provided by the CPU and the XL450 platform enable multiple NVMe or high-throughput networking adapters.

Power envelope and thermal planning

The TDP of 130W requires explicit planning for rack power density, cooling capacity, and ambient temperature. In dense rack deployments, estimate peak power per chassis and ensure environmental controls can handle short-term spikes (e.g., during compile or AVX-heavy jobs). HPE ProLiant XL450 Gen10 chassis airflow and fan speed profiles are tuned for this class of processor, but integrators should still verify power distribution and redundancy for mission-critical systems.

Compatibility and platform integration

HPE ProLiant XL450 Gen10 server family compatibility

When populating HPE ProLiant XL450 Gen10 systems, confirm server firmware levels (iLO, system ROM) and HPE qualification matrices. The HPE 874655-B21 part is validated to operate within factory-tested BIOS configurations and iLO feature sets, enabling hardware monitoring, remote management, and firmware update pipelines.

Firmware and iLO management

Leverage HPE iLO tools for remote health checks, firmware orchestration, and secure remote console capabilities. The processor’s presence and microcode updates are surfaced through HPE management utilities; keep microcode and firmware up to date to benefit from performance improvements and vulnerability mitigations.

Interoperability with memory and expansion options

The 874655-B21 XL450 Gen10 supports multiple memory configurations and a range of expansion cards. Use HPE-certified DIMMs to ensure full compatibility and optimal channel balancing. For workloads requiring high I/O, configure NVMe drives on supported risers and verify that the CPU and platform provide the necessary PCIe lanes without creating contention.

Databases and middleware

Relational databases, in-memory caches, and middleware tiers benefit from the CPU’s frequency and cache characteristics. For OLTP systems, prioritize fewer sockets with faster per-core performance; for OLAP or large parallel queries, consider scaling horizontally or using higher core counts in other SKUs. The 3.2GHz baseline is advantageous for transactional throughput and query latency.

High-performance computing and specialized compute

While the Xeon-Gold 6134 is not targeted at maximum core density HPC nodes, it fits smaller HPC clusters and specialized compute tasks (simulation tasks that require fast scalar throughput, engineering applications that rely on fewer fast cores). Pair with fast NVMe storage and high-bandwidth networking for best results.

Thermal throttling and performance drops

Thermal throttling typically manifests as lower sustained clock speeds under load. Investigate ambient temperature, fan operation, and chassis airflow obstructions. Reconfirm the server’s power settings and whether AVX workloads are triggering deeper power states.

Unexpected reboots and machine checks

Machine check exceptions may indicate marginal power delivery, overheating, or socket-level issues. Check event logs, run memory tests, and validate power supply health. Replace suspect components in a controlled manner to isolate faults.
