Product information

Description

The Intel E835-CQDA2 is a high-performance internal network adapter designed to meet the demanding connectivity requirements of modern enterprise server environments. Utilizing advanced fiber optic technology and a PCI Express interface, this network card delivers exceptional data transfer speeds of up to 200,000 Mbit/s, ensuring reliable and high-speed communication for data-intensive applications.

Advantages

This network adapter offers significant performance enhancements through integrated technologies such as Intel Data Direct I/O, which streamlines data processing by allowing direct communication between the controller and the processor cache. The inclusion of iWARP and RDMA support facilitates low-latency fabric services, while SR-IOV and Flexible Port Partitioning enable efficient virtualization by allowing a single physical port to be shared across multiple virtual machines. Furthermore, the hardware-based Virtual Machine Device Queues significantly reduce I/O switching overhead, leading to improved system throughput and overall efficiency.

Suitable for

High-performance enterprise server environments
Data centers requiring high-speed fiber connectivity
Virtualization platforms utilizing SR-IOV
Applications demanding low-latency network communication

When it may not be suitable

This network card is specifically engineered for server-grade hardware and high-speed fiber optic infrastructures. It is not compatible with standard desktop computers or consumer-grade networking equipment that lacks PCI Express slots or fiber optic support.

Key specifications

Connectivity technology: Wired
Interface: Fiber
Host interface: PCI Express
Maximum data transfer rate: 200,000 Mbit/s
Networking standards: IEEE 1588

How to use

Installation requires inserting the card into an available PCI Express slot on a compatible server motherboard. Once physically installed, ensure the server operating system recognizes the device and install the appropriate drivers provided by Intel. Configure the network settings and virtual functions through the server's management interface to optimize performance for your specific network architecture.

What to consider before purchase

Ensure your server chassis has an available PCI Express slot compatible with this card.
Verify that your existing network infrastructure supports fiber optic connections.
Check for compatibility with your server's operating system and virtualization software.

Usage recommendations

For optimal performance and security, ensure that the server firmware and network drivers are kept up to date. Utilize the built-in virtualization features like SR-IOV to maximize the efficiency of your virtual machine deployments.
