FAQs

Does the switch support RoCEv2? What specific ECN, PFC, and DCB features are supported?
Supports RoCEv2, ECN/PFC/DCBX, and Easy RoCE, and configures the above parameters with one click.
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.

For a configuration of 8–10 cameras and 3–4 compute nodes plus one NVMe-oF server, do you think a single switch would suffice, or should we consider a hierarchical switch setup?

Two switches are recommended for this scale to provide dual-homing for all devices, ensuring both redundancy and high availability for your deployment.

Does the switch support containerized applications (e.g., PB, INT, ZTP)? Is it based on the FRR routing stack?
Our AsterNOS inherits SONiC’s containerized architecture, fully supporting containerized applications such as Packet Broker and In-band Network Telemetry. Additionally, based on the FRRouting (FRR) routing stack, it provides robust and reliable control plane functionality.
Are automation interfaces such as gNMI, gRPC, REST API, and NetConf supported? Can the switch be integrated with OpenStack, Kubernetes, and Ansible?
Our AsterNOS fully supports these automation interfaces, providing flexible network management and configuration capabilities and enabling integration with mainstream automation and orchestration platforms, including OpenStack, Kubernetes, and Ansible.
Is the switch compatible with mainstream 100G optical modules on the market (e.g., LR4, SR4, CWDM4, ZR, ZR4)?
We support 100G-SR4, LR4, CWDM4, ZR, and ZR4 standards, and are compatible with mainstream vendor modules. Our design follows standard specifications, and hardware tuning is required during integration. During testing, 5W modules are selected for use, and a sufficient power budget has been reserved. Since the typical power consumption of 100G ZR4 modules in the market is around 6W, there is no specific limitation on the number of supported modules.
