The HPE P11338-B21 548SFP+ PCIe 3.0 x8 10 Gigabit SFP+ x 2 Network Adapter is engineered to deliver dependable, high-performance Ethernet connectivity for modern enterprise servers and data center infrastructures. As organizations continue to virtualize workloads, adopt cloud computing, and deploy bandwidth-intensive applications, the demand for reliable 10 Gigabit networking has become increasingly important. This dual-port network adapter is designed to provide exceptional throughput, low latency, and enhanced network efficiency while maintaining compatibility with a broad range of HPE server platforms.

Equipped with dual 10 Gigabit SFP+ ports and a PCI Express 3.0 x8 interface, the adapter offers fast communication between servers, storage systems, virtualization hosts, and enterprise networking equipment. It enables businesses to improve application responsiveness, optimize resource utilization, and support high-density computing environments without compromising stability or scalability. Whether deployed in virtualization clusters, database servers, private cloud infrastructures, or high-performance computing environments, the HPE P11338-B21 provides the performance and flexibility required for demanding enterprise workloads.

Designed for High-Speed 10 Gigabit Ethernet Connectivity

Modern organizations require networking solutions capable of handling continuously increasing volumes of data traffic. The HPE P11338-B21 addresses this requirement by delivering dual-port 10 Gigabit Ethernet connectivity over SFP+ interfaces. Compared to traditional Gigabit Ethernet adapters, 10GbE significantly increases bandwidth while reducing transmission bottlenecks across the network infrastructure.

Each SFP+ port supports high-speed communication with compatible optical transceivers or direct attach copper cables, enabling administrators to deploy networking solutions tailored to specific data center layouts. The flexibility of SFP+ technology allows organizations to select suitable media types and cable lengths while simplifying future network upgrades.

Dual-Port Architecture for Improved Network Performance

The inclusion of two independent SFP+ ports enhances both bandwidth availability and operational flexibility. Organizations can configure each port separately for different workloads, combine both ports using link aggregation technologies, or dedicate individual interfaces to storage, virtualization, backup, or application traffic.

Dual-port connectivity also contributes to improved fault tolerance by supporting redundant network paths. If one network connection becomes unavailable, traffic can continue flowing through the second interface, minimizing service interruptions and supporting continuous business operations.

PCI Express 3.0 x8 Interface Maximizes Data Throughput

The PCIe 3.0 x8 host interface provides ample bandwidth between the network adapter and the server motherboard. This high-speed connection ensures that the adapter can fully utilize dual 10 Gigabit Ethernet ports without becoming constrained by internal bus limitations.

PCI Express Gen3 technology delivers higher bandwidth efficiency than previous generations while reducing communication latency between system components. This architecture is particularly beneficial in environments where servers process large volumes of simultaneous network traffic, such as virtualization clusters, cloud infrastructures, storage servers, and enterprise databases.

Optimized for Modern Enterprise Servers

Reliable SFP+ Connectivity for Flexible Network Deployment

Support for Optical and Direct Attach Solutions

The SFP+ interface offers organizations considerable deployment flexibility. Depending on infrastructure requirements, administrators can utilize fiber optic transceivers for long-distance communication or Direct Attach Copper (DAC) cables for short-range server-to-switch connections within racks.

This modular approach enables cost-effective network expansion while simplifying cable management throughout the data center. Organizations can gradually upgrade network segments without replacing the entire infrastructure, making SFP+ technology an attractive investment for evolving enterprise environments.

Scalable Infrastructure Planning

Scalability remains one of the primary advantages of SFP+ networking solutions. As business requirements evolve, organizations can upgrade optical modules or switch infrastructure while continuing to utilize the same network adapter. This flexibility extends hardware lifespan and reduces long-term networking costs.

Built for Virtualization and Cloud Computing

Virtualized data centers require network adapters capable of supporting multiple virtual machines transmitting data simultaneously. The HPE P11338-B21 is well suited for virtualization environments because it provides sufficient bandwidth to support numerous workloads sharing the same physical server.
