It features a fiber interface with a maximum data transfer rate of 200,000 Mbit/s and utilizes a PCI Express host interface. Supporting IEEE 1588 precision time protocol, this wired network adapter ensures reliable, high-speed connectivity for server infrastructure and enterprise-grade networking applications.

## Long description

The Intel E835-CQDA2 OCP 3.0 Network Adapter is a high-performance networking solution engineered for modern data center environments. This adapter provides exceptional throughput, supporting data transfer rates up to 200 Gbps, making it an ideal choice for bandwidth-intensive server applications. By utilizing a fiber interface and the PCI Express host interface, it ensures reliable, low-latency connectivity for enterprise-grade infrastructure.
Advantages
This network adapter leverages advanced technologies such as Intel Data Direct I/O and iWARP/RDMA to significantly reduce latency and improve data processing efficiency by allowing direct communication with the processor cache. The inclusion of SR-IOV and Flexible Port Partitioning enables efficient virtualization, allowing a single physical port to be shared across multiple virtual machines with guaranteed quality of service. Furthermore, the adapter supports Virtual Machine Device Queues to offload switching tasks from the virtual machine monitor, which enhances overall system throughput and reduces CPU overhead.
Suitable for
High-performance server infrastructure
Enterprise-grade data centers
Virtualization environments requiring high I/O density
Applications demanding low-latency network communication
This adapter may not be suitable for standard desktop computers or small office environments that lack OCP 3.0 compatible slots or do not require high-speed fiber connectivity. It is specifically designed for server-grade hardware and may be incompatible with consumer-level motherboards.
Key specifications
Connectivity technology: Wired
Interface: Fiber
Host interface: PCI Express
Maximum data transfer rate: 200,000 Mbit/s
Networking standards: IEEE 1588
To use the Intel E835-CQDA2, ensure your server chassis supports the OCP 3.0 form factor. Install the card into the designated OCP slot and connect the appropriate fiber optic cables to the QSFP28 ports. After physical installation, ensure the latest drivers and firmware are installed on your server operating system to enable full functionality of features like SR-IOV and VMDq.
What to consider before purchase
Verify OCP 3.0 slot compatibility on your server motherboard
Ensure your network infrastructure supports 200 Gbps fiber connections
Check for operating system driver support for advanced features
Usage recommendations: For optimal performance in virtualized environments, configure SR-IOV and VMDq settings within your hypervisor to maximize throughput and minimize I/O overhead.
