CDC discovery can be implemented with bare metal Linux hosts or Linux virtual machines.
Linux NVMe/TCP hosts require the following storage networking:
Two ports, preferably dedicated to NVMe/TCP storage traffic
Two IP addresses, one for SAN A and one for SAN B, each from different subnets.
While LACP is possible on ports carrying NVMe/TCP, best practice is to avoid bonding these ports.A subnet can only be used on one interface per host.
A subnet can only be used on one interface per host.
The following topology shows a typical setup with virtual machines.
