## Long description

The Intel Ethernet Network Adapter E810-CQDA2 Internal Fiber provides 100000 Mbit/s wired connectivity for data centers and enterprise networks. This PCI Express fiber network adapter is designed for high-throughput, low-latency environments and supports advanced offload and virtualization features to optimize server I/O and network performance.
Advantages
The adapter supports iWARP/RDMA for low-latency data transfers using Kernel Bypass, Direct Data Placement and Transport Acceleration. Intel® Data Direct I/O (DDIO) enables direct transfers between the adapter and processor cache to reduce latency and increase I/O bandwidth. Hardware virtualization features such as PCI-SIG SR-IOV, Flexible Port Partitioning and Virtual Machine Device Queues (VMDq) reduce virtual machine I/O overhead and provide predictable bandwidth allocation.
Suitable for
High-performance data center servers
Virtualized environments and cloud platforms
Low-latency storage and HPC applications using RDMA/iWARP
Enterprise networks requiring fiber connectivity and high throughput

How to use
Install the adapter into an available PCI Express slot following your server vendor’s installation guidelines. Connect fiber-optic cables to the appropriate SFP+/QSFP+ or compatible transceivers, configure server BIOS/firmware settings if required, and install Intel drivers and firmware to enable full functionality. Configure networking settings and virtualization options (SR-IOV, FPP, VMDq) in the operating system or hypervisor as needed for your deployment.
Usage recommendations
Use certified transceivers and fiber cabling matched to the adapter’s specifications, keep firmware and drivers up to date, and validate SR-IOV and RDMA features in a test environment before production deployment to ensure stability and optimal performance.
