Server Connectivity Upgrades

Moving a server from 1GbE to 10/25GbE is often the cheapest meaningful performance upgrade in a virtualized environment — storage traffic, vMotion, and backups all breathe again. We stock adapters from Intel (X520/X710/E810), Broadcom, and Mellanox/NVIDIA ConnectX across 1GbE to 100GbE, in standard PCIe plus the OEM-specific formats: Dell rNDC/OCP and HPE FlexibleLOM mezzanine cards that generic listings routinely confuse.

Port type matters as much as speed: SFP+/SFP28 ports need optics or DAC cables matched to your switch, while 10GBase-T models run over Cat6/6A copper. Tell us your server model and switch and we will spec the complete link.

Frequently Asked Questions

What is the difference between OCP/rNDC/FlexibleLOM and a PCIe NIC?

They are OEM mezzanine form factors that occupy a dedicated slot instead of a PCIe slot. They are not interchangeable with standard cards — match the format your server actually has, which we can confirm from the model.

SFP+ or 10GBase-T — which should I choose?

SFP+ with DAC/optics offers lower latency and power and is standard in racks; 10GBase-T runs over existing Cat6/6A copper and simplifies office wiring. The deciding factor is usually what your switch provides.

Do these NICs support virtualization features?

Enterprise adapters we stock support SR-IOV and standard offloads used by VMware, Hyper-V, and KVM. If you need a specific feature (RDMA/RoCE, iSCSI offload), tell us and we will match a card that has it.
