What speeds does the E830-XXVDA2 support per port?

Each of the two SFP28 ports independently supports 25GbE, 10GbE, and 1GbE speeds with auto-negotiation based on connected transceivers or DAC cables. Provides full line-rate duplex performance across all supported speeds without oversubscription.

Is this adapter compatible with PCIe 3.0 servers?

Yes, fully backward compatible with PCIe 3.0 x8 slots operating at 8 GT/s while maintaining complete feature set including SR-IOV, RDMA, and all offload capabilities. Performance scales with PCIe generation for optimal bandwidth utilization.

What virtualization features are supported?

Includes Intel VT-c, SR-IOV with 256 VFs per port, VMDq for flow classification, and flexible port partitioning. Enables direct VM-to-NIC assignment and reduces hypervisor CPU overhead by 50-70% for network-intensive virtual workloads.

Does it support RDMA for storage acceleration?

Supports both iWARP/RDMA and RoCEv2 protocols plus iSCSI/NFS over RDMA (iSER). Enables GPU-direct storage, low-latency inter-node communication, and NVMe-oF acceleration for Ceph and other software-defined storage deployments.

What cabling options work with the SFP28 ports?

Compatible with SFP28 DAC cables, optical transceivers (SR, LR, DR, FR), and AOC active optical cables. Supports all standard 25GBASE optics including multimode and single-mode fiber for flexible reach from rack-scale to campus connectivity.

Is DPDK accelerated packet processing supported?

Yes, fully optimized for Intel DPDK with poll-mode drivers achieving line-rate 25Gbps performance. Ideal for NFV, packet processing appliances, and software switches requiring maximum packet-per-second throughput.
