A Spherelet starts and monitors vSphere pods running on the workload domain cluster. It also enables an ESXi hypervisor to act as a Kubernetes worker node. These roles support the integration of Kubernetes functionality into the vSphere environment, enabling pod lifecycle management and the operation of ESXi as part of a Kubernetes cluster.
To meet the requirement of leveraging an external NFS or a VMFS on FC storage as the principal storage for a new VI workload domain, a new network pool must be created for vMotion and NFS networks. This ensures that the necessary network configurations are in place for data transfer and storage management.
The ideal design for VMware Cloud Foundation domains should adhere to both the minimum requirements for a management domain and the best practices for vSAN clusters. A management domain typically requires at least 4 nodes. For workload domains, vSAN best practices recommend that the nodes within a cluster should have identical configurations, including the number and size of disk groups. Therefore, allocating 4 nodes with 1 vSAN disk group to a workload domain and 8 nodes with 2 vSAN disk groups to another workload domain ensures consistency and optimal performance, aligning with both management domain requirements and vSAN best practices.
The correct order of steps should be: decommission the failed host first to ensure it is properly taken out of service. Then, remove the host from the cluster using cluster APIs to clean up configurations tied to the cluster. After that, commission the new host with the correct network settings to make it ready for cluster integration. Finally, add the newly commissioned host to the cluster using cluster APIs to register it as a part of the cluster. This sequence ensures that the failed host is fully removed before integrating the new one with correct network settings, and only then adding it to the cluster.
Creating a vSphere with Tanzu namespace requires using a DNS-compliant name, as this is necessary for the proper identification and networking of the namespace. Additionally, assigning permissions is crucial to ensure that users have the correct level of access to perform operations within the namespace. These steps are essential components in the initial creation process of the namespace.
