What is the maximum throughput of the Intel E830-CQDA2?

The E830-CQDA2 supports speeds up to 200 Gigabits per second through a single QSFP56 port, or dual 100GbE QSFP28 ports, or mixed-rate configurations down to 10GbE. The Ethernet Port Configuration Tool (EPCT) enables flexible speed selection without hardware changes, allowing single adapter deployment across diverse network topologies.

Which PCIe generations are supported?

The adapter supports PCIe 5.0 x8 for maximum bandwidth on latest server platforms, with fallback compatibility to PCIe 4.0 x16 for broader legacy server support. Both interfaces deliver sufficient bandwidth for 200GbE operation, ensuring compatibility across multiple server generations without performance bottlenecks.

What acceleration technologies are included?

The E830-CQDA2 integrates Data Plane Development Kit (DPDK) for optimized packet processing, Dynamic Device Personalization (DDP) for flexible protocol support, and Open vSwitch (OVS) acceleration for virtualized networking. These technologies reduce CPU overhead and improve application performance in cloud-native and NFV environments without additional software licensing.

Is precision timing supported for financial applications?

Yes, the adapter complies with IEEE 1588 Precision Time Protocol v2 and Precision Time Measurement (PTM) v1.0a, delivering sub-microsecond synchronization. This makes it ideal for high-frequency trading platforms, financial services, network monitoring, and 5G RAN deployments requiring precise timing across distributed systems.

What virtualization features are available?

The adapter supports PCI-SIG SR-IOV for per-VM network isolation, Virtual Machine Device Queues (VMDq) for intelligent traffic steering, Intel VT-c for flexible port partitioning, and on-chip QoS with traffic management. These capabilities enable efficient multi-tenant cloud deployments and virtualized network function architectures.

How much power does the adapter consume?

Power consumption ranges from 11.4W to 21.5W depending on port configuration and traffic patterns. With DAC cables, 1x200Gb configuration consumes 11.6W under traffic and 11.4W idle. With optical transceivers, the same configuration consumes 15.7W under traffic and 15.2W idle, making it highly efficient for large-scale deployments.

What storage protocols are supported?

The E830-CQDA2 supports iSCSI and NFS storage protocols with intelligent offloads, enabling efficient storage area network (SAN) and network-attached storage (NAS) deployments. These offloads reduce CPU overhead and improve storage performance in enterprise and data center environments.
