This chapter covers the following exam topic:
Describe Device Virtualization
There are two types of device virtualization when it comes to Nexus devices. The first is how to partition one physical switch and make it appear as multiple switches, each with its own administrative domain and security policy. That approach has its own benefits and business requirements.
The other option is how to make multiple switches appear as if they are one big modular switch. That approach has its own benefits and business requirements, too. This chapter covers the virtualization capabilities of the Nexus 7000 and Nexus 5000 switches using Virtual Device Context (VDC) and Network Interface Virtualization (NIV).
