Dedicated VMFS datastores on assigned Fibre Channel arrays meet both the performance and separation requirements. VCF supports Fibre Channel-backed VMFS as principal storage for workload domains, making it valid as the primary datastore type for the tier-1 business application cluster. Fibre Channel provides low-latency block storage, resilient pathing, SAN zoning, LUN masking, and mature enterprise performance characteristics. Because the existing FC arrays are partitioned by business unit, dedicated datastores preserve organizational separation and avoid mixing business-unit workloads on shared storage resources. The same dedicated FC-backed VMFS approach can also be used as supplemental storage after the workload domain exists, allowing extra capacity or specialized tiers while maintaining separation. Shared VMFS datastores do not satisfy the organizational separation requirement because they allow multiple business units to consume the same datastore boundary. vSAN is explicitly excluded, so the design must rely on supported non-vSAN storage. Automated VM placement can be supported by VMFS datastore clusters and Storage DRS where datastores are compatible and similarly managed.
