ConnectX-7 400G or 200G — which do I need?

400G NDR suits AI cluster back-ends with PCIe 5.0 hosts; 200G dual-port is the workhorse for mixed virtualization. Tell us your switch fabric and we will match the variant.

Do your NICs support RoCE?

ConnectX-5 and later support RoCE v2; Intel E810 supports iWARP and RoCE. offload licence state is verified on used cards before dispatch.

Can I get OCP 3.0 form-factor cards?

Yes — several E810 and Broadcom 25G SKUs are available in OCP 3.0 SFF. Specify the form factor in your RFQ.

Before you order

Form factor check: stand-up PCIe and OCP 3.0 SFF are not interchangeable. ConnectX-7 400G needs PCIe 5.0 x16; QSFP56 ports accept QSFP28 optics at reduced rate.
Used adapters: PXE/iSCSI offload licence state and bracket height (full / low-profile) are confirmed per batch.
OEM-branded cards (Dell / HPE / Lenovo) may carry locked firmware. Quotes valid ≤ 7 days.
