That is not an easy answer. In the world of UCS, there are several factors that can affect this:
1) Type of IOM (I/O Module) 2) Port config of the IOM (single link or port-channel) 3) Number of inks from the Fabric Interconnect to said IOM 4) Model of adapter in the blade. Depending on the combination of these things, it can be a 10, 20, or 40 GB link. On Wed, Jun 3, 2020, 9:40 PM Lee Trager <1881...@bugs.launchpad.net> wrote: > MAAS 2.7 introduced network testing.
