Access layer - connects servers to network

28

PPDIOO Phases

Prepare - establish organizational requirements
Plan - identify initial network requirements
Design - based on planning outcomes
Implement - build network according to design
Operate - maintain network health
Optimize - proactive management of netowrk

29

Lifecycle approach

Benefits
- lowering the total cost of network ownership
- increasing network availability
- efficient access to applications and services
Lower Costs
- identify and validate technology requirements
- accelerate successful implementation
- improve the efficiency of your network and of the staff supporting it
- reduce operating expenses by improving the efficiency of operational processes and tools
