- Nvidias ConnectX-8 has a GPU-inspired design for networking
- ConnectX-8 delivers an impressive 800 Gbps flow capacity
- Requires PCIe Gen6 X16 for optimal performance
Nvidia has revealed the ConnectX-8 Supernic, a new map that can with an 800 Gbps capacity doubling the 400 Gbps registered for its predecessor.
Designed by this map is a departure from conventional networking surface cards (NICS) as it looks like more traditional GPUs, with ConnectX-8 apparently set to focus on improving air flow and cooling efficiency with its low-profile design, back plate and advanced internal layout.
This device also comes with a large connector on the back, suggesting the potential of multi-host cable connections, possibly linking to additional CPUs or acting as a PCI-switch output.
Multi-host connections and flexibility
The ConnectX-8 Supernic is a single port card that delivers high bandwidth that necessitates advanced PCIE connection.
Specifically, it requires either PCIE GEN6 X16 or two Gen5 X16 links to operate effectively, suggesting that the card’s performance exceeds what a single CPU can handle. This capacity is in line with the need for robust connection in Nvidia’s Grace platforms, where the ConnectX-8 serves as a critical component of aids due to the limitations of Grace CPUs.
By integrating these NICs, NVIDIA minimizes dependence on broadcom products, improves system efficiency and flexibility.
Unlike older NIC design, which typically has voluminous cooling bodies and a more utilitarian aesthetic, the ConnectX-8 shows a slim back plate and the overall factor reminiscent of modern GPUs.
The introduction of the ConnectX-8 does not seem to be only about aesthetics as it suggests that Nvidia has a wider vision for AI infrastructure. By customizing its GPU-like design network products, the company is likely to aim to streamline its integration within data centers while delivering high performance capabilities that are important for AI workloads.
