A9927264 Dell 25G ConnectX-5 EN PCIe 3.0 x8 25 Gigabit SFP28 x 2 Network Adapter

The Dell A9927264 25 Gigabit SFP28 X 2 Network Adapter

The Dell A9927264 25 Gigabit SFP28 X 2 Network Adapter built on ConnectX-5 EN architecture with PCIe 3.0 X8 interface represents a high efficiency networking solution designed for modern enterprise infrastructure, data-intensive environments, and next generation cloud computing systems. This category of network adapter focuses on delivering ultra low latency communication, high bandwidth throughput, and advanced hardware offloading capabilities that reduce CPU utilization and optimize server performance across multiple workloads.

This class of network interface card is engineered to support high speed data exchange between servers, storage systems, virtualization layers, and distributed computing environments. The dual port SFP28 configuration allows simultaneous 25 Gigabit Ethernet connections, enabling scalable network design and redundancy options within enterprise and data center deployments.

Advanced 25 Gigabit Data Capabilities

The 25 Gigabit Ethernet standard is designed to bridge the performance gap between traditional 10 Gigabit systems and higher capacity 40 or 100 Gigabit infrastructures. This adapter leverages SFP28 optical and direct attach copper modules to provide flexible connectivity options while maintaining consistent low latency and high throughput performance.

SFP28 interfaces are an evolution of the SFP+ form factor, optimized specifically for 25GbE signaling. This allows enterprises to reuse existing cabling infrastructure in many scenarios while upgrading overall network bandwidth significantly. The dual port configuration enhances load balancing and traffic segmentation capabilities.

Dual Port Network Optimization and Redundancy

With two independent SFP28 ports, the adapter supports redundant network paths, link aggregation, and multi-path data routing. This is particularly important in environments where uptime and fault tolerance are critical. Each port operates independently, allowing administrators to configure advanced networking strategies such as failover protection and traffic distribution.

High Efficiency

The ConnectX-5 EN chipset embedded within this network adapter is designed to offload intensive networking tasks from the central processing unit. It handles packet classification, routing decisions, encryption offloading, and checksum calculations directly on hardware. This significantly reduces system overhead and improves overall server efficiency.

This architecture is particularly beneficial in environments running virtualization platforms, software defined networking, and large scale distributed applications. By minimizing CPU intervention in network processing, systems can allocate more resources to application workloads rather than network management tasks.

High Speed PCI Express Connectivity

The PCIe 3.0 X8 interface provides a robust and scalable connection between the network adapter and the host system motherboard. This interface ensures that the full bandwidth of dual 25 Gigabit ports can be utilized without bottlenecks, supporting sustained high throughput workloads.

PCIe architecture allows direct communication between the network controller and system resources, reducing latency and improving data transfer efficiency. This is particularly important for enterprise servers handling large volumes of concurrent network traffic.

Enterprise Server Platforms

This network adapter category is widely compatible with enterprise grade server systems, including rack mounted servers, blade servers, and virtualization optimized platforms. It is designed to integrate seamlessly with modern data center hardware environments, supporting both Linux and Windows based operating systems.

Scalable Cloud Networking Environments

In cloud computing environments, network performance is a critical factor in determining service quality and operational efficiency. This adapter category supports scalable cloud architectures by providing high bandwidth connectivity between compute nodes, storage systems, and virtual machines.

The dual port 25 Gigabit configuration enables cloud providers to design flexible network topologies that can scale horizontally without significant performance degradation.

RDMA Enabled Data Transfer Capabilities

Remote Direct Memory Access functionality allows systems to transfer data directly between memory spaces without involving the CPU. This dramatically improves data transfer speed and reduces system overhead, making it ideal for high performance computing environments.

RDMA is particularly valuable in scientific computing, machine learning clusters, and real time data processing systems where large datasets must be transferred quickly and efficiently.

Enterprise Security and Network Reliability Features

Security is a fundamental requirement in enterprise networking environments. This adapter includes hardware based security features that assist in protecting data integrity and preventing unauthorized access to network traffic.

Encryption offloading capabilities allow secure data transmission without burdening system processors, ensuring both performance and protection are maintained simultaneously.

Quality of Service

Quality of Service configurations allow prioritization of critical network traffic such as storage replication, database communication, and real time application data.

Advantage Over 10 Gigabit Ethernet Solutions

Compared to 10 Gigabit Ethernet adapters, this category provides significantly higher bandwidth and improved scalability for modern workloads. It reduces network bottlenecks in data intensive environments.

Horizontal Scaling Capabilities

The adapter supports horizontal scaling strategies where additional servers and network nodes can be added without redesigning the entire network infrastructure.

Future Ready Network

Its architecture supports gradual migration toward higher speed networks, allowing enterprises to upgrade infrastructure incrementally without major disruptions.
