This quad-port 10/25Gb SFP28 Ethernet adapter delivers up to 100Gbps aggregate bandwidth, making it an ideal choice for network engineers and infrastructure teams requiring high-density connectivity in space-constrained environments. The HPE P08458-B21 leverages the Intel Ethernet 800 Series (E810-XXVDA4) controller to provide flexible per-port negotiation between 10GbE and 25GbE speeds, enabling seamless integration into evolving datacenter networks without costly forklift upgrades.
Built for enterprise performance, this HPE adapter features PCIe 4.0 x16 host connectivity and a low-profile form factor with full-height bracket included, ensuring compatibility across HPE ProLiant Gen10 and Gen10 Plus servers as well as HPE Apollo systems. Advanced offload capabilities—including TSO, LRO, RSS, and checksum offload—reduce CPU overhead, while RoCEv2 support and hardware-based flow steering via Flow Director optimize RDMA and storage workloads. The adapter supports Dynamic Device Personalization (DDP) for intelligent packet processing, TLS inline offload for encrypted traffic acceleration, and SR-IOV virtualization for multi-tenant deployments. Full compliance with IEEE 802.3by, 802.3ae, 802.1Q VLAN, and 802.3ad LACP standards ensures robust interoperability, and OS support spans Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi. HPE iLO and Smart Update Manager (SUM) integration streamline lifecycle management and deployment across your infrastructure.
