IBM Mellanox Connect-IB 56Gb FDR Adapter

The IBM 98Y8995 Mellanox CB194A is a Connect-IB InfiniBand network adapter card built for high-performance computing clusters and enterprise storage fabrics. It delivers up to 56Gb/s FDR bandwidth through a QSFP port on a PCIe 3.0 x16 interface. The card is qualified for IBM System x and Power Systems platforms requiring ultra-low latency connectivity.

Suited for HPC clusters needing RDMA offload

This adapter suits administrators deploying InfiniBand fabrics on supported IBM servers where CPU offloading and scalable throughput are required. It is not for buyers who need Ethernet connectivity or standard LAN networking. It is not for builders whose platforms lack a PCIe 3.0 x16 slot or InfiniBand-enabled firmware.

Installation requires compatible IBM server firmware

The card installs into a full-length PCIe 3.0 x16 slot on qualified IBM System x or Power Systems hardware. A QSFP InfiniBand cable and FDR-capable switch complete the link. What usually goes wrong is inserting the card into an unsupported chassis or missing the required firmware baseline for Connect-IB recognition.

Questions about this item

Does my server need a PCIe 3.0 x16 slot to install this 98Y8995 adapter?

Yes, the card requires a full PCIe 3.0 x16 slot to deliver the 56Gb/s FDR bandwidth through its QSFP port.

Will this Connect-IB card interoperate with my existing 40Gb InfiniBand switches and cables?

The adapter runs at FDR speeds up to 56Gb/s and is compatible with 40Gb InfiniBand fabrics using standard QSFP connections.

How can I verify the Mellanox CB194A is operating at full 56Gb/s after installation?

Check the link status in your InfiniBand management tools; it should report an active FDR connection at 56Gb/s on the QSFP port.
