Product information

Description

The Intel E835-XXVDA4 is a high-performance internal network adapter engineered for demanding data center environments and enterprise-grade server infrastructure. Featuring four SFP28 ports, this adapter supports high-speed connectivity up to 25 Gbps per port, utilizing a PCIe 4.0 x16 interface to ensure maximum throughput. It integrates advanced technologies such as Intel Data Direct I/O, SR-IOV, and iWARP/RDMA to optimize data processing, reduce latency, and enhance virtualized environment performance.

Advantages

This network adapter offers significant improvements in I/O efficiency by allowing direct communication between the adapter and the processor cache, bypassing system memory to reduce power consumption and latency. The inclusion of SR-IOV and Flexible Port Partitioning enables the physical device to be divided into multiple virtual functions, ensuring efficient resource allocation across virtual machines. Furthermore, the support for IEEE 1588 precision time protocol makes it highly suitable for time-sensitive networking applications, while VMDq technology offloads switching overhead from the virtual machine monitor to the hardware, resulting in superior overall system throughput.

Suitable for

  • High-bandwidth server networking
  • Data center virtualization and cloud infrastructure
  • Time-sensitive networking requiring IEEE 1588 precision
  • High-performance computing environments

This adapter may not be suitable for standard desktop workstations or consumer-grade hardware that lacks PCIe 4.0 x16 slots or requires different physical connector types. It is specifically optimized for server-grade motherboards and enterprise operating systems.

Key specifications

  • Interface: 4 x SFP28 ports
  • Host Interface: PCIe 4.0 x16
  • Maximum Data Rate: 25 Gbps per port
  • Connectivity: Wired, Fiber
  • Networking Standards: IEEE 1588, SR-IOV, VMDq, iWARP/RDMA

To use the Intel E835-XXVDA4, install the card into an available PCIe 4.0 x16 slot on a compatible server motherboard. Ensure the server is powered down and disconnected from the power source during installation. Once physically installed, secure the bracket and connect the appropriate fiber-optic cables to the SFP28 ports. After booting the system, install the latest drivers provided by Intel to ensure full compatibility and access to advanced features like SR-IOV and iWARP.

What to consider before purchase

  • Verify that your server motherboard has an available PCIe 4.0 x16 slot
  • Ensure your network infrastructure supports 25GbE fiber-optic connections
  • Check operating system compatibility with the latest Intel network drivers
  • Confirm the physical space requirements within your server chassis
Usage recommendations: For optimal performance in virtualized environments, ensure that SR-IOV is enabled in both the system BIOS and the host operating system settings. Regularly update the adapter firmware and drivers to maintain security and stability.
