Our environment consists of: * A primary datacenter with more than three Proxmox VE hosts connected = to a SAN storage array. * A secondary datacenter with equivalent infrastructure (Proxmox VE hos= ts and a storage array). * Storage replication from the primary array to the secondary array. * Both datacenters are connected through a LAN network with very low la= tency and sufficient bandwidth, so network performance is not a concern. Our objective is to ensure business continuity in the event of a complete f= ailure of the primary datacenter. In such a scenario, we would like the virtual machines to be started in the= secondary datacenter with as much automation as possible and with minimal = manual intervention. We would appreciate your guidance regarding the following points: 1. Does Proxmox VE officially support this type of architecture? 2. Would you recommend a stretched cluster across both datacenters, or t= wo independent Proxmox clusters? 3. What are the requirements regarding quorum, fencing, HA, networking, = and storage? 4. Is it possible for Proxmox HA to automatically start the virtual mach= ines in the secondary datacenter if the primary datacenter becomes complete= ly unavailable? 5. What are the main limitations or considerations for this design? 6. What would be the recommended Proxmox architecture and best practices= to achieve an automated Disaster Recovery solution in this scenario? Any recommendations, documentation, or real-world deployment examples would= be greatly appreciated. Thank you very much for your assistance. Best regards, Iv=E1n M=E9ndez Systems Administrator
