Product information

Description

The Intel E835-XXVDA4 is a high-performance 25Gbps 4-port SFP28 fiber network interface card engineered for demanding data center environments and professional server infrastructures. This internal adapter utilizes a PCI Express host interface to provide reliable, high-speed wired networking capabilities, ensuring seamless data transmission for enterprise-grade applications.

Advantages

This network interface card offers significant performance benefits through advanced technologies such as Intel Data Direct I/O, which allows the controller to communicate directly with the processor cache to reduce latency and power consumption. The inclusion of iWARP/RDMA support provides low-latency fabric services, while the PCI-SIG SR-IOV capability enables efficient sharing of I/O resources across multiple virtual machines. Furthermore, Flexible Port Partitioning and Virtual Machine Device Queues ensure optimized throughput and reduced overhead in virtualized environments, making it an ideal choice for complex, high-traffic network setups.

Suitable for

  • High-density data center server environments
  • Enterprise-level virtualization and cloud computing
  • High-speed fiber optic network backbones
  • Applications requiring low-latency data processing

This card may not be suitable for standard desktop computers or home office workstations, as it requires specific server-grade hardware and PCI Express slots. It is also not intended for wireless network configurations, as it is strictly designed for wired fiber optic connectivity.

Key specifications

  • Connectivity: Wired fiber
  • Host interface: PCI Express
  • Ports: 4 x SFP28
  • Maximum data transfer rate: 25000 Mbit/s
  • Networking standards: IEEE 1588 precision time protocol

To use the Intel E835-XXVDA4, install the card into an available, compatible PCI Express slot within your server chassis. Once physically installed, connect the appropriate SFP28 fiber optic cables to the four ports. Ensure that the server operating system has the latest drivers installed to enable full functionality of the advanced virtualization and offloading features.

What to consider before purchase

  • Verify compatibility with your server motherboard and PCI Express slot generation
  • Ensure your network infrastructure supports SFP28 fiber optic connections
  • Confirm that your operating system supports the advanced features like SR-IOV and VMDq
For optimal performance and stability, ensure that your server firmware and network drivers are updated to the latest versions provided by the manufacturer.
