10GbE / 25GbE PCIe Network Adapters

Intel X710, Mellanox ConnectX, Broadcom NetXtreme-E for high-throughput servers

About PCIe 10GbE / 25GbE Network Adapters

10GbE and 25GbE PCIe network adapters are the connectivity backbone of modern virtualization, hyperconverged, and storage clusters. Pro Disk Network stocks Intel X710 / E810, Mellanox ConnectX-3 / ConnectX-4 / ConnectX-5, Broadcom NetXtreme-E (BCM57414 / BCM57810), and Chelsio T6 adapters in 2-port and 4-port SFP+ (10GbE) and SFP28 (25GbE) form factors.

These cards support hardware offload for VXLAN, NVGRE, RoCE v2, and DPDK kernel-bypass - critical for low-latency database, AI/ML, and HPC workloads. For VMware ESXi, every card we list ships with the certified driver bundle in the box or as a documented download.

Frequently Asked Questions

Are these adapters compatible with VMware ESXi / vSphere?

Yes. Intel X710/E810, Mellanox ConnectX-4/5, and Broadcom NetXtreme-E are all on the VMware HCL. Drivers are included on the VMware installation ISO from vSphere 6.7+, with current drivers downloadable from VMware’s site. We can match you to the exact firmware version your ESXi build requires.

Will an HPE-branded Mellanox card work in a Dell PowerEdge?

Physically yes (same Mellanox silicon), but Dell’s iDRAC may flag the card as "non-OEM" and refuse to update firmware. For best management integration, match the card brand to the server brand: HPE-branded for HPE ProLiant, Dell-branded for PowerEdge.

Do you stock 25GbE breakout cables (1x QSFP28 to 4x SFP28)?

Yes. Both passive DAC breakout (3m and 5m) and active optical breakout (10m and 20m). See our DAC / QSFP+ pages for details.

What is the difference between PCIe Gen3 x8 and Gen4 x8 for these cards?

A PCIe Gen3 x8 slot delivers 7.88 GB/s in each direction - more than enough for a single 25GbE port (~3.1 GB/s) or a 100GbE port (~12.5 GB/s, which would be Gen4 x16). For 100GbE single-port operation, ensure the slot is Gen4 x16 (or Gen3 x16 in compatibility mode). Dell PowerEdge R740 / R740xd has Gen3 x16 slots; R750 / R760 has Gen4 x16.
