Detailed Specifications
HPE 665240-B21 - 1 Gb 4-Port FlexibleLOM Ethernet Adapter
Overview :
The HPE 665240-B21 is a 1 Gb four-port FlexibleLOM Ethernet adapter designed for use in HPE ProLiant rack and scalable servers, aimed at network engineers who require reliable connectivity in virtualised or segmented network environments. This adapter supports full line-rate performance on all four ports while maintaining low power consumption, enabling efficient use in dense server configurations. It is suitable for deployment in data-centres, enterprise server farms or hyperconverged infrastructures, fitting into Gen8-through-Gen10 HPE ProLiant servers. The adapter integrates into HPE's management ecosystem (such as through HPE iLO and Sea of Sensors) and supports modern I/O features including virtualization offloads and precision time-stamping, making it well-suited to mixed-workload situations where network performance and server resource efficiency matter.
Key Features :
Four independent 10/100/1000 Mb/s RJ-45 ports
FlexibleLOM form-factor, PCIe 2.1 ×4 interface
Intel I350 controller with full line-rate per port
Supports Jumbo Frames, Large Send Offload, VLAN tagging
