FAQs

What are the forwarding performance and total bandwidth of the 64×100G switch?
Under no packet loss conditions, our switch’s performance test metrics are: Packet Forwarding Rate: 7600 Mpps, Bandwidth: 6.4 Tbps.
Which RDMA-capable NICs (e.g., Mellanox ConnectX-4/5/6, Broadcom, Intel) and drivers have been validated on your CX-N series switches?

All major RDMA-capable NICs, including Mellanox ConnectX-4/5/6, Broadcom, and Intel, as well as their standard drivers, have been validated on our CX-N series switches.

If you have any recommendations for setting up an NVMe-oF, any documentation/case studies?

We have successfully deployed NVMe-oF solutions for several customers. Please contact bd@cloudswit.ch to get case study~

We want your switches to do AI inference, Our working AI inference config looks somewhat like: Camera (SRT) -> Compute Node NIC -> GPU -> [Compute Node NIC -> NVMe-oF + Compute Node NIC -> Other Nodes for processing]. If you have any past setups similar to that, are there any solutions to include Camera SRT feed or GigE feed into RoCEv2 congestion management?

Yes, by marking or prioritizing the camera SRT or GigE traffic at the switch egress or ingress, the switches can treat it as high-priority and apply PFC/ECN-based congestion management, similar to RDMA traffic. However, SRT itself implements its end-to-end congestion control at the application layer and does not utilize or require DCQCN, which is specific to RDMA flows.

What are the key advantages of Asterfusion’s 64×100G data center switch based on the Marvell Teralynx 7 chip?
Compared with Broadcom Tomahawk2 (packet buffer 42MB, forwarding rate 4200 Mpps), the TL7-based Asterfusion 64x100G has a larger packet buffer (70MB) and a higher packet forwarding rate (7600 Mpps).
Does the solution support BGP-EVPN with VXLAN overlay? Can it be used to build a large Layer-2 fabric in a Spine-Leaf topology?
Our AsterNOS provides BGP-EVPN and VXLAN Overlay support, supporting 1,000 VXLAN tunnels and 4,000 VXLAN gateways, and meets the needs of modern data centers for flexible and efficient large-scale Layer 2 networks.
