Description
LAN minimum configuration solution is for basic connectivity with expected minimum uptime of 99.5 percent. This configuration should be implemented for basic cost-effective LAN connectivity where uptime is not mission-critical and the number of users is relatively small.

Benefits
- Provides a consistent and manageable approach for provisioning LAN services across the NIH. Can enable a breadth of configurations that are neither under- nor over-configured.
- Allows the alignment of technical requirements to business needs by implementing LAN service levels based on availability requirements. For example, if only 99.5 percent uptime is required for a specific location, a design pattern can be developed for that requirement. Because it has interchangeable layers, this design pattern can be easily customizable for varying uptime requirements.
- Provides an efficient use of expensive network resources, such as printers, scanners, and other network devices.
- Provides the ability to aggregate large numbers of users onto expensive WAN transport services.
- Reduces costs relative to the high availability configuration by eliminating equipment redundancy.
Limitations
- Does not provide the fault-tolerance and availability shown in the LAN high availability pattern.
