Virtualization is changing the focusApplications no longer tied to server hardware

Applications are now objects moving through the network

The data center needs to evolve

Computing andnetworking have to change Data must to be accessible, distributed and protected

Management needs to be native, not an after-thought

We are leading Data Center innovation Unified Fabrics, Unifed Network Services, Unified

Computing, Unified Storage, Virtualization, Open

Management

We have a Proven Track Record Network, Storage, Virtualization we are market makers!

Before Virtualization

One-to-one ratio betweenservers/OS/application andnetwork port

Physical servers connected intothe network via access ports(single VLAN)

No longer a one-to-one relationshipbetween server and network port

VMotion

! VMotion may move VMsacross physical portspolicymust follow

! Impossible to view or applypolicy to locally switched traffic
