Detailed Specifications
HPE 819841-B21 Intel Xeon E5 2660 v4 Processor Kit
Overview
The HPE 819841-B21 is a factory-kit processor targeted at enterprise rack and blade servers (notably the ProLiant BL460c Gen9 series). It features the Intel Xeon E5-2660 v4 processor with 14 physical cores, a base clock of 2.0 GHz, 35 MB Smart Cache, and a 105 W TDP. This combination gives a balance of core-density and power efficiency in a well-proven Gen9 platform.For an IT operations team managing virtualization hosts or high-thread-count application servers, this part allows reuse of existing chassis and infrastructure while boosting CPU concurrency. Because it supports the LGA2011-v3 socket and the associated Broadwell-EP architecture, it's compatible with many dual-socket Gen9 servers, enabling a cost-effective refresh path.In practical deployment, one would install this kit into a compatible HPE ProLiant server (blade or rack), ensure proper cooling and BIOS/firmware support, and then proceed to populate memory and I/O to match the workload. It's ideal for scenarios where many VMs or multi-threaded applications run and where you want to extend the life of existing Gen9 hardware rather than doing a full platform migration.With its 14-core count and Broadwell-EP architecture, the 819841-B21 is a solid choice for compute-heavy but still cost-sensitive deployments within enterprise or service-provider environments.
Key Features
14 physical cores / 28 threads for high concurrency in virtualization or multi-tenant workloads.
2.0 GHz base clock with turbo capability (~3.2 GHz) for mixed single-thread and multi-thread performance.
35 MB Smart Cache shared across cores, reducing latency in high-thread scenarios.
105 W TDP keeps rack power and cooling costs manageable in dense deployments.
Compatible with LGA2011-v3 socket and HPE ProLiant Gen9 servers (e.g., BL460c Gen9) × enabling upgrade without full chassis replacement.
