HPE P08458-B21

Intel E810‑XXVDA4 4‑Port 10/25 Gb/s Gigabit Ethernet Adapter (SFP28, PCIe Gen4 ×16

The HPE P08458‑B21 is a high-performance server Network Adapter featuring four 10/25 GbE SFP28 ports on aPCI Express 4.0 ×16 plug-in card. Based on the Intel E810‑XXVDA4 chipset, it delivers up to 3.13 GB/s per port and aggregate bandwidth of ~100 Gb/s full duplex. Compatible with HPE Gen10 Plus servers (e.g. ProLiant DL360/380/385, DL325, DL345, DL365), this card supports advanced networking offloads including SR‑IOV, RoCE v2 (RDMA), DDP, DDIO, and tunneling protocols (VXLAN/NVGRE). It accelerates workloads in virtualized, cloud, or storage-rich environments by reducing CPU usage while boosting throughput via hardware-level assistance

Features

The adapter is built on the Intel Ethernet 800 Series platform, offering robust compatibility with HPEinfrastructure and validated across multiple server models. It supports both IPv4 and IPv6 networking, Wake-on-LAN (WOL), and PXE boot functionality. With PCIe 4.0×16 interface, it ensures peak connectivity and low latency for demanding workloads. Features such as RoCE v2 and iWARP, along with tunneling offloads, empower efficient storage networking and NVMe-over-Fabrics deployments. Delivery includes SR‑IOV for VM scalability, RSS for multi-core CPU balancing, and DDIO/DDP support for high-performance I/O. Firmware validation ensures secure platform updates and integrity.

Advanced Options

When sourced as OEM‑new, the adapter qualifies for HPE limited lifetime support policies. Refurbished models may include 90‑day warranty from select vendors. The spare-part equivalent P10582‑001 is also recognized in HPE parts catalogues. It provides future-ready flexibility for growing data center applications, virtualization, machine learning, and storage workloads.Constructed for high-density, latency-sensitive server environments, this adapter offers near line-rate throughput for demanding workloads while offloading protocol processing to the NIC. Supported offloads—SR‑IOV, tunneling, RDMA—accelerate virtualization and storage traffic, significantly reducing CPU overhead. RSS support distributes load across CPU cores, ensuring consistent performance under multi-thread workloads. The PCIe Gen4 interface provides future-proofed bandwidth and low host latency.
