LEGACY NETWORK

• Separate networks for each traffic type

• LAN, SAN, HPC

• Unique infrastructure

• Server adapters

• Fabric switches

• Cables

• Separate management schemes

• Inherently costly and complicated

CONVERGED NETWORK SOLUTION

• Phased deployment (no rip & replace)

• Continue to use existing LAN and SAN investments

• Protocol selection based upon application/business requirements

• Single network to manage & maintain

Requirements• Multiple interfaces required• VM Traffic (vSwitch)• Management (Low bandwidth,

High priority)• VMotion (Backup – High

bandwidth)• Storage interface

Challenges• Multiple adapters, cables• Higher TCO• Limited I/O slots in blade

TCO Reduction• Fewer adapters, cables, &

fabrics!

Seamless deployment• No change to Hypervisors• No dependency on fabrics!

Flexible configuration• Dynamic bandwidth allocation,

sharing• Resource management in

hardware

Quality of Service• Differentiation of traffic

KEY MESSAGE: FIELD SUCCESS

Provide a customer case study to reinforce concepts

Suggested content Get a customer to approve the use of their name for maximum

impact “Genericize” a real-world deployment if you can’t get a customer to

agree to be featured Include information about customer’s before/after results Highlight speed or ease of deployment
