Spine switches for Fusion HCI HA setups with FDF

IBM Fusion HCI offers different HA configurations for data replication with Fusion Data Foundation (FDF) as storage provider.

Because FDF cannot separate the storage traffic into a dedicated storage network, the HCI uplinks and the customer network is used for data replication between multiple racks (R-DR or 3rack HA).

Starting with Fusion 2.11, IBM can offer spine switches for the above purpose.
My understanding is, that these spine switches have to be configured and run by the customer!

The idea:
IBM should provide a blueprint on how these spine switches should be configured.
IBM Expert Labs can then apply this blue print as part of the installation and configure the switches. The configuration is static and will probably not change of the lifetime.
Monitoring of the spine switches is important!
In case this cannot be done from the beginning in the Fusion UI,
IBM should provide another way of monitoring within the blueprint.

Note:
IBM is not responsible for the "run" of the spine switches, like they are not responsible for the operation of the OpenShift cluster.
The attached diagram shows an R-DR setup, while 3 rack-HA would be as well covered with 2 spine switches.
