The Intel Ethernet Network Adapter E830-CQDA2 is a high-performance, next-generation network interface card designed for demanding data center, cloud service, and edge computing environments. This adapter delivers exceptional throughput with support for speeds up to 200GbE through dual QSFP28 ports, providing an aggregate bandwidth of 400 Gbps per card. Built on Intel's proven Ethernet controller architecture, the E830-CQDA2 leverages PCIe 5.0 x8 or PCIe 4.0 x16 connectivity, delivering approximately 63 GB/s (504 Gb/s) bidirectional bandwidth without creating host bus bottlenecks. The adapter supports flexible port configurations through the Ethernet Port Configuration Tool (EPCT), enabling deployment across 200GbE, 100GbE, 50GbE, 25GbE, and 10GbE infrastructure. Advanced features include Dynamic Device Personalization (DDP) for workload optimization, Data Plane Development Kit (DPDK) acceleration for packet processing, and Open vSwitch (OVS) support. With ultra-low latency architecture and hardware-accelerated offloads, the E830-CQDA2 minimizes CPU overhead while delivering millions of packets per second, making it ideal for financial trading, high-frequency databases, and clustered compute applications. The adapter requires only standard 75-watt PCIe slot power delivery with no auxiliary connectors, simplifying installation in modern data center infrastructure.

Frequently asked questions
What is the maximum aggregate bandwidth of the E830-CQDA2?
The E830-CQDA2 delivers 400 Gbps aggregate bandwidth through its dual 200GbE QSFP28 ports. The PCIe 5.0 x8 interface provides 63 GB/s (504 Gb/s) bidirectional bandwidth, which comfortably exceeds the 50 GB/s (400 Gb/s) requirement of the dual ports, ensuring zero host bus bottlenecks and full line-rate performance.
Is the E830-CQDA2 compatible with PCIe 4.0 servers?
Yes, the adapter is backward compatible with PCIe 4.0 x16 slots. While PCIe 5.0 x8 provides optimal performance with 63 GB/s bandwidth, PCIe 4.0 x16 delivers 32 GB/s, which is still sufficient for dual 200GbE ports. The adapter will operate at reduced bandwidth in PCIe 4.0 slots but maintains full 200GbE port functionality.
What virtualization features does the E830-CQDA2 support?
The adapter supports Intel Virtualization Technology for Connectivity (VT-c) including SR-IOV (Single Root I/O Virtualization), VMDq (Virtual Machine Device Queues), flexible port partitioning, and on-chip QoS with traffic management. These features enable efficient multi-tenant cloud deployments, direct VM access to network ports, and reduced CPU overhead in virtualized environments.
What is the latency performance of this adapter?
The E830-CQDA2 is engineered for ultra-low latency with sub-microsecond packet processing and the capability to handle millions of packets per second per port. The hardware-optimized data paths and cut-through switching architecture minimize latency, making it ideal for high-frequency trading, real-time databases, and latency-sensitive AI/ML workloads.
Does the E830-CQDA2 require auxiliary power connectors?
No, the adapter requires only 75 watts of power delivery from the PCIe slot itself, eliminating the need for auxiliary power connectors. This simplifies installation and reduces cabling complexity in data center deployments, particularly beneficial for high-density server configurations.
What optical and copper media types are supported?
The E830-CQDA2 supports comprehensive optical transceivers including 200GBASE-SR4, DR4, and FR4 for multi-mode and single-mode fiber deployments over various distances. For cost-effective short-reach connections, it supports passive and active Direct Attach Copper (DAC) cables for 200GbE and 100GbE, as well as breakout cables for 25GbE and 10GbE configurations.
What acceleration technologies are enabled on this adapter?
The E830-CQDA2 includes Dynamic Device Personalization (DDP) for workload optimization, Data Plane Development Kit (DPDK) support for accelerated packet processing, and Open vSwitch (OVS) acceleration. These technologies enable efficient packet processing, reduced CPU overhead, and optimized performance for cloud-native and virtualized workloads.
