Multi-Subnet DHCP

Multi-Subnet DHCP enables Omnia to support rack-based network provisioning where each rack has its own /24 subnet for the Admin (PXE) network. This architecture allows large-scale HPC and AI/ML deployments to have per-rack management subnets instead of a single shared subnet, improving scalability, failure isolation, and operational efficiency.
