FAQs

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~

Is IPv4: 288K / IPv6: 144K the maximum hardware-supported routing entries? Will it affect other features?
IPv4: 288K / IPv6: 144K are the maximum values supported by the switch hardware. Thanks to the Layer-3 Wire-Speed Routing Engine, it achieves wire-speed routing without affecting other features.
Is 2600Mpps wire-speed forwarding? What packet sizes are supported?
2600Mpps is the packet forwarding value tested based on small packets of 64B. Under 64B small packets, it is not wire-speed forwarding. The minimum byte size for wire-speed forwarding is 170B, at which point the packet forwarding rate is 2631Mpps.
Does it support the FRR routing stack? Does it support the full protocol stack for BGP/OSPF/ISIS?
AsterNOS is based on the FRRouting (FRR) stack, providing powerful and reliable control plane functionality. FRR currently supports the following protocols: BGP, OSPFv2, OSPFv3, RIPv1, RIPv2, RIPng, IS-IS, PIM-SM/MSDP, LDP, BFD, Babel, PBR, and OpenFabric. It fully supports BGP, OSPF, and ISIS protocol stacks.
Does it support hybrid networking, e.g., part traditional vendor devices and part your devices?
It supports hybrid networking. We are a standard Ethernet device, supporting universal standard protocols and fully compatible with traditional vendor devices.
