2 Introduction Regardless of business activity or size, all information technology (IT) groups have similar needs Provide secure, uninterrupted availability to local and remote resources Computing Storage Networking Telecommunications circuits

3 Introduction (cont d) Organizations driven by heavy use of both existing and new IT resources require: Uninterrupted network availability Rapid provisioning and reconfiguration capabilities Strong capital and operational cost management

4 Introduction (cont d) The impact on data center network physical layer connectivity? There has never been a greater need for: Performance Density Flexibility Manageability

5 Typical data center network architecture Servers Switches Storage directors Disk arrays Management consoles

6 Multiple applications sharing the same data center network Traditional data Voice Audio / Video Security / Life safety Building / Facilities management

7 Simultaneous network traffic flows within each application Application flows Storage flows Security flows Diagnostics and management flows
