vMotion requires consistent network labels (A) and shared storage (C, D) for the same VM files. Virtual hardware versions (B) can usually differ as long as the underlying ESXi supports them, though EVC might be necessary if CPU instruction sets differ greatly.

ESXi can use iSCSI/FC to connect to SAN LUNs (A), and vVols (C) provides per-VM management. In- guest NFS (B) is possible but not a typical approach for hosting VM disks. Combining vSAN and array- based storage (D) into a single datastore is not supported.

When deploying an NSX Edge cluster in a VMware Cloud Foundation (VCF) environment, it must be deployed in the management domain. The management domain is responsible for managing and orchestrating various resources, including the NSX Edge cluster, which is crucial for network virtualization and security within the environment.

SRM (A) automates and orchestrates failover; stretch clusters enable cross-site vMotion for resilience (C); and testing DR in a controlled environment (D) ensures readiness. Storing backups only on local host datastores (B) creates a single point of failure and is not recommended.

esxcli commands (for example, esxcli network vsan cluster get) can validate and configure vSAN network settings.
vmkping allows you to test VMkernel adapter connectivity on the vSAN network to confirm reachability and MTU correctness.
RVC provides specialized vSAN commands (such as vsan.network_info and health check commands) tailored for diagnosing vSAN network misconfigurations.
