The HPE 851279-B21 2 Ports 10Gbps Fast Ethernet Adapter
The HPE 851279-B21 2 Ports 10Gbps Fast Ethernet SFP+ OCP Mezzanine Network Adapter is engineered to deliver high-performance networking capabilities for enterprise-grade computing environments where speed, reliability, and scalability are critical. Designed as an Open Compute Project (OCP) mezzanine adapter, this networking component integrates seamlessly into compatible HPE server architectures, enabling enhanced data throughput and optimized network communication between servers, storage systems, and enterprise applications. Built with advanced 10 Gigabit Ethernet technology, it ensures that modern workloads such as virtualization, cloud computing, database management, and high-performance computing can operate efficiently without bottlenecks.
OCP Mezzanine Form Factor
The adapter follows the OCP mezzanine design standard, which is widely adopted in modern data center architectures for its modularity and efficiency. The mezzanine structure allows the adapter to be installed directly onto the motherboard through a dedicated slot, eliminating the need for traditional PCIE expansion cards in many configurations. This approach not only saves physical space inside the server chassis but also improves airflow and thermal performance. The compact design is particularly beneficial in dense rack environments where space optimization is a priority.
Dual-Port 10Gbps Connectivity
At the core of the HPE 851279-B21 adapter is its dual-port configuration, providing two independent 10Gbps SFP+ interfaces. These ports are designed to support simultaneous high-speed data transmission, enabling redundancy and load balancing across network connections. The dual-port setup ensures that even in case of a link failure on one port, the second port can maintain connectivity, thereby increasing system resilience and uptime for mission-critical applications.
Efficient Signal Processing
The adapter incorporates advanced signal processing mechanisms that ensure minimal latency and maximum throughput. By optimizing packet handling at the hardware level, the device reduces CPU overhead on host systems, allowing server processors to focus on application-level tasks rather than network processing. This efficiency is particularly important in environments running virtual machines or containerized applications where network traffic is high and constant.
High-Speed 10GbE Performance Capabilities
With support for 10 Gigabit Ethernet per port, the adapter is capable of handling large volumes of data transfer with ease. This high bandwidth capacity is essential for enterprise workloads such as data analytics, virtualization clusters, and large-scale storage replication. The adapter ensures that data packets are transmitted with minimal delay, maintaining consistent network performance even under heavy traffic conditions.
SFP+ Interface and Connectivity Flexibility
The SFP+ interface design provides flexibility in choosing transceiver modules based on specific deployment requirements. Users can select from a range of optical fiber or copper-based SFP+ modules depending on distance, bandwidth, and infrastructure design. This adaptability makes the adapter suitable for both short-range intra-data center communication and longer-range inter-building connectivity.
Hot-Swappable Module Design
One of the significant advantages of SFP+ technology is its hot-swappable capability, allowing network administrators to replace or upgrade transceiver modules without shutting down the system. This feature significantly reduces downtime during maintenance or upgrades, ensuring continuous network availability in enterprise environments.
Compatibility with Existing Network
The adapter is designed to integrate seamlessly with existing Ethernet-based infrastructures. It supports standard networking protocols and can operate in heterogeneous environments where multiple generations of networking hardware coexist. This backward compatibility ensures smooth migration paths for organizations upgrading from lower-speed networks.
Improved Storage Networking Performance
In storage-heavy environments, network adapters play a crucial role in ensuring fast data replication and retrieval. The dual 10Gbps ports allow high-speed communication with storage arrays, improving backup operations, disaster recovery processes, and real-time data synchronization across multiple storage nodes.
High-Speed Networking Capability
This adapter is engineered to deliver ultra-fast 10Gbps throughput, ensuring low-latency communication between servers, storage systems, and network infrastructure components. It is ideal for virtualization, cloud computing, and high-performance computing workloads.
Optimized OCP Mezzanine Architecture
Designed with the Open Compute Project (OCP) mezzanine form factor, this adapter allows efficient server integration while reducing physical space requirements and improving airflow within server chassis.
Scalability and Flexibility
The adapter supports scalable infrastructure growth, making it suitable for expanding data centers and cloud-based environments. Its flexible architecture ensures compatibility with evolving network demands.
