vNV Deployment Scenarios and Arista NetVisor UNUM


As the Arista Networks Unified Cloud Fabric™ scales to accommodate more services, such as multi-tenancy and analytics, additional resources can be beneficial. In these cases, centralizing the services in a fabric node with more CPU and memory than a typical network switch provides a powerful and cost-effective means of scaling.


Enter Virtual Netvisor or vNV, a virtual machine running Arista Networks’ NetVisor OS operating system. Once deployed and added to a fabric, vNV enables administrators to offload multiple vNET managers and other services from physical network nodes, freeing up switch resources.


Deployment Options and Use Cases


Virtual Netvisor installs on a VMware ESXi server as a virtual machine. Used as a separate fabric node, vNV connects to the fabric through the management network and supports both greenfield and brownfield environments.


Virtual Netvisor typically deploys with UNUM™, Arista Networks’ fabric management, analytics, and automation platform, to move resource consumption from a fabric node known as a seed switch onto the more powerful vNV virtual machine. vNV is especially helpful in environments with high numbers of traffic flows.
