HP P11338-B21 – Ethernet 10Gb 2‑port 548SFP+ Adapter
Overview :
The HP P11338‑B21 is a dual‑port 10 Gigabit SFP+ network adapter engineered for enterprise servers and storage systems where high throughput and low latency are required. It delivers two 10 Gbps SFP+ ports via a PCI Express 3.0 x8 interface, enabling connectivity to high‑speed fibre or DAC links. The adapter supports hardware offload features, jumbo frames, overlay network offloads (VXLAN/NVGRE/GENEVE) and RDMA (RoCE v1/v2), making it suitable for virtualised server environments, storage networks and converged infrastructure. It is designed for deployment in rack‑mount or blade servers in data centres, cloud infrastructure, high‑performance compute clusters or edge data nodes. It integrates with HPE’s ProLiant and Apollo server platforms and can be managed via common server management tools, facilitating consistent network infrastructure rollout.
