EA3 artifact I-9: Wiring Closet Diagram
The wiring closet is a equipment room or server room, that contains hubs, switches, and other network components that is often connected through a vertical backbone cable to the main equipment room, which is usually in the basement of the building (in a multifloor building).
EA3 artifact I-8: Data Center/Server Room Diagram
This artifact is an overhead diagram of the information technology network center. This diagram can be part of the set of blueprints, and is maintained electronically to support the numerous changes to network center(s) and server rooms that can be expected over a number of years.
EA3 artifact I-7: Rack Elevation Diagram
This diagram provides a front and rear view of each of the information technology equipment racks that go into a network center, server room, and/or wiring closet. This diagram supports the NI-5 and NI-6 diagrams and is maintained electronically to support the numerous changes that can be expected over a number of years.
EA3 artifact I-6: Wireless Connectivity Diagram
The use of wireless networks gives possibilities for new forms of connectivity inside and outside the enterprise network.
EA3 artifact I-5: Cable Plant Diagram
The Cable Plant Diagram shows physical connectivity between voice/data/video networks throughout the enterprise and to global suppliers. The diagram should show the types of cable (fiber, CAT-6, etc.) and the bandwidth (T-1, OC-3, etc.) of each cable run between network centers, server rooms, wiring closets, and external connections.
EA3 artifact I-4: Technology Forecast
The Technology Forecast supports and relates to the I-3 Technology Standards Profile. The Technology Forecast documents expected changes in any of the standards listed in the I-3 artifact, where future changes appear to be happening or about to happen.
EA3 artifact I-3: Technical Standards Profile
The Technology Standards Profile is a listing of business services and associated technologies that are accepted by the enterprise as being a primary or secondary standard. Further detail can be added regarding particular types of standards.
This best practice involves an ongoing governance process and uses the network inventory, capital equipment inventory, and other EA artifacts to maintain a accurate picture of the hardware, software, and other equipment are active in the business and technology operating environment.
Configuration Management in EA documentation is very important, because the transition between current and future architectures is ongoing.
EA3 artifact I-2: Hosting Concept of Operations
The infrastructure sourcing model is an important architectural decision. Cloud-based hosting solutions are becoming more and more popular.
EA3 artifact I-1: Network Diagram
The Network Diagram shows the physical connections between the enterprise’s voice, data, and video network… including external Wide Area Networks (WANs) and Local Area Networks (LANs)… also called ‘extranets’ and ‘intranets.’
EA3 artifact A-11: Software License Inventory
Software Asset Management (SAM) enables strategic infrastructure planning, prevents over-licensing and under-licensing, and identifies over-deployment of hardware and its associated costs.
It also allows the IT department to control exactly what software an employee can access and significantly reduces the opportunity for users to introduce unlicensed software on to networks.
