Description
HPE 654782-B21 Intel Xeon E5-2620 Processor Kit
The HPE 654782-B21 processor kit pairs HPE engineering with the reliable Intel Xeon E5-2620 microprocessor to deliver balanced server-class performance for ProLiant platforms. Designed for 2.00 GHz nominal clock speed, 15 MB of Level 3 cache and a six-core (hexa-core) architecture, this CPU is optimized for virtualization, business applications and mixed-workload datacenter use in the ProLiant DL360p Gen8 family.
Key Technical Specifications
- Product Line: Intel Xeon
- Model / Series: E5-2620
- Manufacturer part: HPE 654782-B21
- Processor Type: Server microprocessor
- Cores / Threads: Hexa-core (6 cores)
- Base Frequency: 2.00 GHz
- QPI (QuickPath Interconnect): 7.20 GT/s
- Level 3 Cache: 15 MB L3
- Process Technology: 32 nm lithography
- Socket: FCLGA2011
- Thermal Design Power (TDP): 95 W
Performance Characteristics
This processor offers a solid combination of multicore throughput and cache capacity, making it suitable for:
- Virtualized environments and hypervisor hosts
- Database and transactional workloads with moderate concurrency
- Business intelligence and analytics at small-to-medium scale
- Web/application servers and multi-tenant services
Clock Speed and Throughput
The 2.00 GHz base frequency provides predictable single-thread responsiveness while the six physical cores enable parallel processing across simultaneous workloads. For burst and multi-threaded applications the L3 cache and QPI bandwidth help reduce latency and improve inter-socket communication in dual-CPU configurations.
Cache and Memory Interaction
With 15 MB of L3 cache, the E5-2620 reduces memory access overhead for frequently used data and instruction streams, benefiting database indices, caching layers and in-memory operations. QPI at 7.2 GT/s supports efficient data transfer between CPU and chipset or paired processors.
Compatibility and Supported Platforms
This HPE kit is specifically qualified for HPE ProLiant systems. Confirm compatibility prior to deployment to ensure proper firmware and chassis support.
Verified Server Compatibility
- HPE ProLiant DL360p Gen8 (primary supported platform)
- Suitable for similar HPE Gen8 rack-mount servers that accept FCLGA2011 Xeon E5 family CPUs (verify server model and BIOS/firmware)
Recommended Validation Steps
- Check HPE ProLiant platform documentation for CPU support lists.
- Confirm ECC memory compatibility and populate ranks according to HPE’s guidance.
- Run post-installation hardware diagnostics and stress tests.
Performance Characteristics and Workload Fit
The E5-2620's six-core configuration with a moderate base clock offers a favorable performance-per-watt profile. While raw single-thread frequencies are modest compared to high-clocked variants, the processor shines in parallelized workloads and environments where CPU core count and cache hierarchy matter more than peak single-thread bursts. Use cases ideally matched to this processor kit include:
- Virtual machine consolidation for small-to-medium VM densities
- Lightweight database hosting and caching layers
- Web application and middleware stacks
- Batch processing, job schedulers, and CI/CD agents
For latency-sensitive, single-thread-dominant applications (for example, high-frequency trading or some legacy ERP modules), higher-frequency Xeon SKUs may be preferable. However, for balanced enterprise environments where reliability, platform integration, and cost effectiveness are primary concerns, the HPE 654782-B21 offers a robust option.
BIOS Settings and Optimizations
For virtualization hosts, enable appropriate virtualization extensions (Intel VT-x/VT-d) and choose power profiles that balance performance and efficiency. Consider:
- Configuring NUMA awareness in the hypervisor for memory locality
- Disabling unneeded legacy I/O protocols to reduce boot complexity
- Applying the latest microcode patches to resolve errata and improve stability
Cost Efficiency and Total Cost of Ownership (TCO)
The HPE 654782-B21 kit offers a blend of acquisition cost and operational efficiency. Calculate TCO by factoring:
- Initial hardware cost versus alternative CPU SKUs
- Power consumption and cooling costs over expected lifetime
- Support and warranty expenses tied to OEM parts
