Detailed Specifications
HPE 874795-B21 CPU Enablement Network Adapter Kit
Overview
The HPE 874795-B21 is an internal server kit that enables installation of a second CPU and activates associated I/O pathways in select HPE ProLiant Gen10 systems. This kit ensures full utilization of the dual-processor architecture by unlocking memory channels, PCIe lanes and integrated networking when transitioning from single to dual CPU configurations. It includes adapter modules or interconnect hardware that integrate with the server's riser/back-plane design and permits balanced traffic across the platform during virtualization, high-throughput computing or storage-intensive workloads. The device is targeted for compute-dense racks and enterprise virtualization hosts where capacity scaling and high bandwidth are required in one server chassis.
Key Features
Enables support for second CPU in certified Gen10 servers
Unlocks full memory channel and PCIe lane bandwidth
Integrates internal network adapter/link-hardware for balanced I/O
Designed for server upgrade paths without full system replacement
