Telecom Infrastructure Blocks for Red Hat is a bring-your-own-networking solution that uses a customer's existing switches. Customers can use their own top-of-rack and out-of-band management switches or purchase switches from Dell Technologies. Telecom Infrastructure Blocks for Red Hat requires the following connectivity between clouds and components:
- The infrastructure cloud must have connectivity to all iDRACs in all cloud servers in the different data centers and Cell Sites.
- The DNS server of the infrastructure cloud must resolve forward and reverse look ups of all cloud servers in the data centers and Cell Sites.
- The DNS server of the management cloud must resolve forward and reverse look ups of all workload clouds in the data centers and Cell Sites.
- Red Hat Advanced Cluster Management for Kubernetes in a management cloud must have connectivity to all iDRACs in all cloud servers that Red Hat Advanced Cluster Management for Kubernetes manages.
- A management cloud and workload clouds must be connected to the Internet so they can pull Red Hat OpenShift Container Platform content, or images, from Red Hat.
- For disconnected installations, the management and workload clouds require connectivity to a local registry such as Red Hat Quay or Harbor.
The clouds, their components, and their high-level network connections are shown in the following figure:
