Product information

Description

The Intel E835-CQDA2 is a high-performance internal network adapter designed to meet the demanding connectivity requirements of modern data centers and enterprise server environments. Utilizing advanced fiber optic technology and a PCI Express host interface, this card provides exceptional throughput and reliability for high-speed networking tasks. It is engineered to handle massive data loads, making it an essential component for infrastructure that requires consistent, low-latency communication across complex network architectures.

Advantages

This network adapter offers significant performance benefits through its support for iWARP and RDMA, which facilitate low-latency fabric services by bypassing traditional kernel overhead. The integration of Intel Data Direct I/O Technology allows the adapter to communicate directly with the processor cache, effectively reducing system memory usage and power consumption while increasing overall bandwidth. Furthermore, the inclusion of PCI-SIG SR-IOV and Flexible Port Partitioning enables efficient virtualization, allowing a single physical port to be divided into multiple virtual functions to optimize resource allocation and quality of service for virtual machines. The hardware-based Virtual Machine Device Queues further enhance performance by offloading switching tasks from the virtual machine monitor, resulting in superior throughput.

Suitable for

  • High-performance data center server clusters
  • Virtualization environments requiring high I/O density
  • Cloud computing infrastructure
  • Enterprise-grade network backbones
  • Applications requiring low-latency RDMA communication

This adapter may not be suitable for standard desktop computers or workstations that lack the necessary PCI Express slot configuration or server-grade cooling requirements. It is also not intended for home networking setups where 200 Gbit/s speeds exceed the capacity of existing local infrastructure.

Key specifications

  • Connectivity technology: Wired
  • Host interface: PCI Express
  • Interface: Fiber
  • Maximum data transfer rate: 200000 Mbit/s
  • Networking standards: IEEE 1588
  • Port configuration: 2 x QSFP28

How to use

Installation requires a compatible server motherboard with an available PCI Express slot. Once the card is physically seated, ensure the server is powered down and properly grounded. After installation, the operating system will typically require the latest Intel network drivers to recognize the device and enable advanced features like SR-IOV and RDMA. Configuration of virtual functions and port partitioning should be performed through the server's BIOS or the operating system's network management interface to align with your specific virtualization requirements.

What to consider before purchase

  • Verify that your server chassis supports the physical dimensions and thermal requirements of the card.
  • Ensure your network switch infrastructure supports 200 Gbit/s fiber connections.
  • Check for compatibility with your specific server operating system and virtualization platform.
  • Confirm that your motherboard provides sufficient PCI Express lanes to achieve maximum throughput.
Usage recommendations: For optimal performance and stability, always keep the firmware and drivers updated to the latest versions provided by Intel. Ensure proper airflow within the server rack to maintain operating temperatures during high-load operations.
