Business Drivers

• IT as a Service

• Faster IT delivery

• Predictable Cost Structures

4

Virtualization Support

• Virtualization

• Tight integration with hosts

• Virtualized network components

5

Virtualization Support

What are the drivers?

•Server Virtualization – More high throughput traffic per physical box•Blade Servers – Increased server density•Video – Conferencing, live meetings, high-def, Telepresence

6

Network Virtualization

• Converged I/O (Unified Fabric)

• High capacity links

• Reduced number of cables

• Decrease data center floor space requirements

• Lower power/cooling requirements

7

Traditional Data Center Design

• Parallel Networks: Ethernet and Fiber Channel

• Asset Utilization Rates are low

• Power/Cooling Efficiencies are low

• Cable Density can be problematic

8

Unified Data Center Design

• Reduces the number of HBAs and cables

• Reduces the number of devices on the floor

• Better Power/Cooling efficiencies and operational management

• Provides same reliability, latency, and security capabilities as FC Fabrics

• Provides same ubiquitous capabilities as Ethernet

10Gb Implementation with vPC


16

Virtual Device Contexts

• Create up to 4 virtual switches in one Nexus 7000- separate memory space (processes and threads), L2/L3 port assignments, VLAN and VRF environments- separate NX-OS instances in every respect

• Per-VDC fault isolation

• Separate Role Based Access Control (RBAC) per VDC

• External connections required if inter-VDC communication is required
