3. Cisco Application Networking Services
 Wide Area Application Services
Consolidate IT infrastructure from the branch into the DC…
… and make sure your users do not suffer from performance
degradation!
 Data Center Application Services
Make sure your DC can scale in a flexible and cost-effective
manner with Cisco ACE Load Balancers
Virtualizing your Load Balancing Infrastructure is crucial for the
road to the "cloud"
Pay-as-you-grow, with license-based scalability models, that
avoid costly fork-lift upgrades

Fewer interfaces means:
Fewer cards pro Server ⇒ power savings ⇒ $$$
Neater cabling ⇒ Better airflow ⇒ power savings ⇒ $$$
Fewer network switches ⇒ $$$

6. Nexus Fabric Extender
 Top-of-the-Rack (ToR) designs offer
best cabling designs, but imply a lot
of devices to manage
Top of the Rack (ToR)
 End-of-the-Row (EoR) designs are
optimum from a network perspective:
fewer devices to manage, but cabling
is costly

9. I/O Consolidation + Fabric Extender
Traditional switching FCoE + Fabric Extender
 Multiple points of management  Unified Fabric with Fabric extender
FC  Single point of management
Ethernet
Blade switches  Reduced cables
Fiber between racks
 High cable count

10. I/O Consolidation and VM-aware
networking
 Reduced CPU utilization  More VMs per server
through hypervisor bypass
 VM-aware networking for FC
(VMDirectPath technology)
and Ethernet
 vhbas supported!
