Dual-site data center infrastructure with mirrored topology across FSH and DSA locations, each anchored by Cisco UCS routing and switching fabric. Network traffic flows from PK Router through FK Switch to DNS/DHCP services via Infoblox 3-Node Cluster, storage via PureStorage FlashArray X70, and compute via ESXi 8.03 VM Cluster hosting 400+ virtual machines per site. This architecture demonstrates high-availability design with redundant networking, clustered services, and distributed compute capacity across geographically separated facilities. Fork this diagram to customize IP addressing, add inter-site replication links, or integrate monitoring and backup tiers. The dual-router connection pattern enables load balancing and failover resilience critical for enterprise SLAs.
