Reference Architecture Disclaimer

This reference architecture is provided for planning and discussion purposes. VMware licensing costs are not included in hardware BOQ and must be procured separately. vSAN capacity varies based on storage policy (FTT, deduplication, compression). DR site sizing depends on RPO/RTO requirements. Final configuration will be customized based on workload analysis and growth projections.
