HPE P24837-B21 10/25 GbE Dual-Port SFP28 Adapter
Overview
The HPE P24837-B21 is a dual-port network interface adapter designed for server uplinks in compute-dense or storage-converged environments. It supports both 10 Gb/s and 25 Gb/s link speeds per SFP28 port, enabling up to 50 Gb/s aggregate throughput when fully utilised. With a PCI Express form-factor, the card is suitable for HPE ProLiant and Synergy platforms certified for this adapter. It supports advanced offload features such as link aggregation (LACP), jumbo frames and VLAN tagging, making it a strong fit for virtualised workloads, high-speed storage networking and modern converged infrastructure. Its low-profile design allows installation in rack servers where expansion slot space is at a premium.
