Overview
The Intel E810-XXVDA4 concentrates four 25GbE SFP28 ports — 100 Gb/s aggregate — into a single PCIe 4.0 x16 slot, which is the standard layout for storage heads and aggregation nodes that speak to many 25G clients at once.
Per-port auto-negotiation to 10G lets the same card serve a mixed fleet during a gradual 10G-to-25G migration, and the E810 timing block (hardware PTP) covers vRAN and industrial synchronisation requirements without a separate timing card.
Key Benefits
Four 25G ports, 100 Gb/s from one x16 slot. Mixed-speed migration with per-port 10G negotiation. RDMA + hardware PTP as standard. Unified E810 driver across the 25G/100G family.
Applications
NVMe-oF storage heads, Ceph/vSAN aggregation nodes, virtualized RAN (vRAN) hosts, industrial PTP-synchronised data acquisition, and dense 25G server fan-out.
