What we verify before it ships
- PCIe link width and negotiated speed
- Firmware version burned into the adapter
- RDMA and RoCE capability flags
- Loopback and traffic pass on every port
- SFP / QSFP cage integrity and optical link test
Check before you order
- Confirm PCIe lane width and the bracket form factor fit your server chassis.
- RDMA support requires matching software on both ends — the adapter, the driver and the fabric all have to agree.
