Introduction to esx-msc-3.1.1g.ova Software
The esx-msc-3.1.1g.ova is a preconfigured virtual appliance designed for deploying VMware’s Multi-Service Controller (MSC) 3.1.1g release. This Open Virtualization Archive (OVA) file provides centralized management for distributed network services across hybrid cloud environments, including SD-WAN orchestration, traffic optimization, and policy-based security enforcement.
Developed for VMware vSphere/ESXi 7.0 U3+ environments, this version enhances interoperability with Cisco Nexus 9000 Series switches and integrates with Cisco Application Centric Infrastructure (ACI) fabric automation workflows. The MSC appliance supports API-driven configurations compatible with Kubernetes-based cloud-native architectures.
