HPE P08445-B21 

524SFP+ 10Gb 2‑Port Network Card

The HPE P08445‑B21 524SFP+ Network Card  is a high-efficiency dual-port adapter offering 10 Gbps Ethernet connectivity through two SFP+ interfaces. Designed for HPE ProLiant Gen10 servers and storage solutions—including DL360 and DL380—it delivers excellent throughput with minimal CPU impact. Ideal for virtualization, cloud, and storage workloads, this card includes support for advanced features like RDMA (RoCE/iWARP), tunnel offloading (VXLAN, NVGRE, GENEVE), SR‑IOV, RSS, MSI-X, and DPDK. This powerful combination enables increased VM density, improved performance, and optimal server CPU utilization. The plug‑in PCIe Gen 3 x8 form factor ensures seamless compatibility and full bandwidth under load, providing reliable and scalable network performance for enterprise environments.

Features

Engineered for modern data centers, this adapter leverages a Mellanox ConnectX‑4 Lx chipset to deliver stable and efficient 10 Gb SFP+ connectivity across two independent ports. The PCI Express 3.0 x8 interface ensures full utilization of available bandwidth while maintaining low latency for network-intensive operations . The card supports jumbo frames up to 9.6 KB, reducing overhead and enhancing throughput for large packet flows and storage traffic Compliant with key networking standards such as IEEE 802.3ae (10GBase‑X), IEEE 802.1Q (VLAN tagging), IEEE 802.3ad (LACP), IEEE 802.1Qbb/Qaz/Qau/Qbg and IEEE 802.1AX for high reliability and traffic prioritization, the adapter supports full feature sets for enterprise fabrics . Additional capabilities include PXE boot, IPv6 support, team clustering, Wake‑on‑LAN, RSS, MSI‑X, secure boot, VMware NetQueue and Microsoft VMQ, and hardware tunnel offload for overlay networks These features minimize CPU use and bolster performance in virtualized or containerized environments.

Advanced Options

Built for enterprise-grade applications, this network adapter offers consistent and low-latency 10 Gb performance. Its Mellanox chipset ensures stable operation under heavy workloads, with support for jumbo frames reducing packet overhead and improving throughput for storage and clustered applications  Advanced offloading to handle RDMA, overlay networks, and virtualization protocols significantly lowers host CPU load, boosting system performance and VM density. Support for SR‑IOV, VMQ/NetQueue, MSI‑X, and RSS ensures efficient packet processing and fair resource distribution across VMs and containers The dual-port design enables redundancy and flexible network path design. .
