Why the Network is Changing

Desire for VM-level access-layer policyVirtualization is driving higher link utilizationMore demanding role of network (i.e. DRS)Current approaches lead to inconsistent network policies

Problems:

VN-Link:• Extends network to the VM • Consistent services • Coordinated, coherent management

VMotion• VMotion may move VMs

across physical ports—policy must follow

• Impossible to view or apply policy to locally switched traffic

• Cannot correlate traffic on physical links—from multiple VMsVLAN

VN-Link: Virtualizing the Network Domain

Virtual machine aware network and storage services

Abstract physical and logical infrastructure

Virtual machines are the new data center building block

2003 – VMware introduces VMotion

2004 – AMD-v and Intel VT-x: VM-aware CPU

2006 – VMware Infrastructure 3.0

2006 – NPIV: VM-aware Fibre Channel Storage

2007 – VMware introduces ESXi

Today – VN-Link: VM-aware networking services
