Your Storage Cluster Is Bottlenecked at 25GbE. The Next Step Is Not Two More 25GbE Ports. It Is One 100GbE Port.
Adding a second 25GbE port and configuring LACP gives you 50 Gbps aggregate — but no single flow exceeds 25 Gbps. A vMotion migration of a 500 GB VM still takes 3 분. A Ceph recovery after a drive failure still runs at 25 Gbps per node. The Intel E810-CQDA2 is a dual-port 100GbE QSFP28 adapter that delivers 100 포트당 Gbps, 회선 속도, with RDMA support and the same Intel E810 driver stack that VMware, RHEL, and Windows Server have shipped inbox since 2021. It is the NIC that turns your network bottleneck into headroom.

100GbE vs 4x 25GbE LACP — The Single-Flow Performance Gap
| 대본 | 1x 100GbE (E810-CQDA2) | 4x 25GbE LACP | 우승자 |
|---|---|---|---|
| Single 500 GB VM vMotion | ~40 seconds (single 100 Gbps flow) | ~160 seconds (single flow limited to 25 Gbps) | 100나르다 (4x faster on single-flow workloads) |
| 10 concurrent 50 GB vMotions | ~40 seconds (10 flows, each gets ~10 Gbps) | ~40 seconds (10 flows distributed across 4x 25GbE ports) | Tie (LACP is effective for multi-flow) |
| Ceph OSD recovery (single PG backfill) | ~40 minutes (100 Gbps single flow) | ~160 minutes | 100나르다 (single-flow dominates in Ceph) |
| NVMe-oF target (multi-initiator, 8 hosts) | ~95 Gbps aggregate (8 flows) | ~90 Gbps aggregate (8 flows across 4 포트) | Tie (multi-initiator distributes well) |
The single-flow advantage of 100GbE matters for three specific workloads: vMotion of large VMs, Ceph recovery, and backup/restore of large datasets. For multi-flow workloads, LACP with 4x 25GbE delivers comparable aggregate throughput at roughly the same cost.
