UCS solution
Unify fabrics
Embed management
Optimize virtualization
Remove unnecessary switches, adapters and management modules
Save over 1/3rd the support infrastructure for a given workload

A single system that encompasses:
Network: Unified fabric
Compute: Industry standard x86 components
VNlink: Distributed Virtual Switch
Efficient scale
Fewer servers with more memory
Lower cost
Fewer servers, switches, adapters, cables
Lower power consumption
Fewer points of management
Unified Computing System

IF -- you attach UCS to a switch configured for vPC (N5K, or N7K)
THEN -- attach UCS with vPC uplinks

UCS Fundamentals
Component reduction, easier to manage
6100 series centre of system
Fluid workloads and Service Profiles enable stateless computing
Integrates with existing infrastructure
