Dell SmartFabric Manager vs Open Virtual Network

Open Virtual Network (OVN) provides logical networking for virtual machine and container environments, intended for cloud management software. It converts virtual network configurations into OpenFlow and organizes them around logical routers and switches. Listed capabilities include distributed virtual routers and logical switches, access control lists, DHCP, and a DNS server. Tunnels or other encapsulations isolate logical networks from physical and virtual networks, allowing overlapping address spaces. Virtual machines can move between physical machines without network disruption, and gateways connect tunnel-based logical networks to physical networks. Examples of cloud-management integrations include OpenStack Neutron’s ml2/ovn plugin and ovn-kubernetes. OVN runs in userspace, needs no kernel modules, and is written in platform-independent C; its generic build guide covers Linux, FreeBSD, and NetBSD hosts. It is free under the Apache 2 license, with on-premises deployment, a centralized control plane, and a Linux and self-hosted platform listing. OpenSSL libssl is optional but recommended for secure connections to OVN database servers.
