 This has consequences for example in scalability where the Kappa limit for a N1000v is 2048 virtual ports against 60000 for a dvS.The Nexus1000v is developed in co-operation between Cisco and VMware and uses the API of the dvS

Because VMware ESX is a leader in the server-virtualization market, software and hardware vendors offer a range of tools to integrate their products or services with ESX.Examples are the products from Veeam Software with backup and management applications and a plugin to monitor and manage ESX using HP OpenView, Quest Software with a range of management and backup-applications and most major backup-solution providers have plugins or modules for ESX.
