MAPPING NETWORKS FOR DAY 3 MANAGEMENT
Day 1 Planning an infrastructure
Requirements, proposals, tenders, contract award, architecture
Day 2 Building the infrastructure
Scheduling tasks, detailed work instructions, testing, verification, sign off
Day 3 Managing and Operating
Ongoing moves/adds/changes, risk management, optimisation,
transformation, centralised support, in/outsourcing, decommissioning.
Installing & connect equipment
Add/change/remove some infrastructure
New requirements & technologies
Fibre, power, copper, IOT
Refurbish / upgrade existing infrastructure
Develop operational management systems
Workflow and change processes
Monitoring, performance, capacity
Re-organise teams
Centralise expertise, outtask/outsource, replace
DAY 3 ACTIVITIES
DAYS 1 & 2Use standards / reference skills where possible
Communicate clearlyRequirements, Proposals
Project plan(s)
Testing and verification
Ongoing support and maintenance (O&M) and
handover documentation / manuals
Infrastructure built – everyone is happy
SOMETIMES WE GET
SOME OF THE ROOT CAUSES
Bad design
Over length cables
Inadequate supervision
Lack of planning
Change process gaps
Limited training
Fault finding
Lack of interest to fix
Lack of time for tasks
AND OCCASIONALLY WE GET…

We try for simplicityNaming depending on
when installed
But its not so easyDifferent technologies
have different needs
After a whileDuplication and evolved
build and naming methods
Less trust in
documentation!
WHICH RESULTS IN
Change tasks taking longer and cost more
Site surveys, emails, meetings
Increased risk of unplanned disruption
On site supervision
Constant rechecking / auditing
Capacity of backbone and network switches
Asset verification
Inadequate records and documentation
Tracing cables with every change (just to make sure the label is right)
1 Step Forward
2 Steps Back
What – Mapping a campus environment
20+ buildings
Why – Change of managed IT service provider
Handover of support roles – understanding of current estate
Resolution of network performance issues
Site development and refurbishment
How - Assess existing sources of knowledge – none!
Naming convention – building/devices, connections
Manual audit – inventory, space, connectivity, plans
Capture into AssetGen infrastructure database
Produce Visio diagrams and capacity reports
Deliverables
Lists of equipment and configurations
Visio schematics – network, campus, rack diagrams, floor layouts
Photos where appropriate to show installation quality and best practice
Backbone infrastructure layout and capacity – fibre / copper
Standards, distances, quality
Issues list
Core fibre location not known – hidden in unmarked cupboard
Logical and physical path views
Remediation /testing required
CASE STUDY 1
LOGICAL OR PHYSICAL DEPENDENCY VIEW?
Requirement:
The router needs a link to the
switch
Easy to understand!

The Project:
The router needs a physical path to the switch. not so easy to
understand or communicate!
THE CASE STUDY 2
What – Mapping multi-site server/equipment rooms 50+
Why – Server and network refresh
Migration to IP telephony
Remediation – safety issues, cooling, power
Increased focus on security and governance
How - Assess existing sources of knowledge – some data
Naming convention – building/devices, connections
Manual audit – environment, inventory, space, ports
Capture into AssetGen infrastructure database
Provide consistent rack and connectivity Visio diagrams
Deliverables
Lists of equipment and rack positioning
Assessment of power sockets and UPS loads – before/after
Assessment of cooling capacity
Rack power delivery – redundancy and options
Energy efficiency of layout and cooling system set points
Photos and videos where appropriate to show installation quality and best practice
Issues list – overcome current challenges – short term
New design and comparison against internal best practice needs
AND IN THE NEXT 10 YEARS+
We’ll all probably have different jobs/roles
Removing “physical” constraints by virtualisation will continue
Computing, networks, cloud, storage, applications
More efficient use of power and hardware
Less efficient use of virtual systems and resources
Fewer people, less physical changes - memory leakage
Even less tolerance of system disruption by users
Increasing sets of controls and auditors – just to make sure..
Best to develop policy and best practices
now as the networks and risks are smaller!
Don’t put all your trust in version 1 of automation
1. Reduced time and cost to implement changes
2. Faster time to identify and resolve faults
3. Common understanding of change risks and impacts across project and operations teams
4. Improved interfaces between technical teams, outsource partners and 3rd party suppliers
5. Separation of design, build and operate teams
6. Infrastructure capacity management and optimisation
7. Implementation of risk management and recovery policies
Many ways to map a network
All may be needed at some stage
WHY MAP NETWORK INFRASTRUCTURE PROPERLY?

H/W Build
1. There will be always be duplication of device views – physical / logical
2. Changes in symbols, attributes, links, position can be automated using Visio
3. Think how many diagrams you need for a project – just a few
4. Think how many diagrams for operational support – just a few thousand….
5. Now you appreciate what AssetGen with Visio automation means
Mapping complex infrastructure with automated updates!
Active / Passive Equipment Build Layout is Needed
- Chassis
- Cards
- Power supplies
- Modular Fibre
COMPLEX DEVICES – CHASSIS/CARD/MODULE
MAPPING ABOVE THE PHYSICAL LAYERS
MAKING IT EASY – USE THE ASSETGEN SYSTEM
Fixed Infrastructure(Cabling, Power, Cabinets, Rooms, Buildings)
Hardware InfrastructurePCs, Network, Servers, UPS, Storage, Other
Virtual InfrastructurePCs, Network, Servers, Storage, DBMS
ApplicationsPC, server, mainframe, SOA
ServicesEnd user, infrastructure, supplier
Business ProcessesDepartmental, Company
Inventory & Connectivity
“Connect”
ServiceMapping
“SysMap”
SQL Server platform
1. Reduce 1000s of spreadsheets into one database
2. One data source for detail, capacity and audit trails
3. One data source for 1000s of Visio diagrams and views
4. One data source to maintain and administer standards
5. One data source to link to monitoring and workflow tools
6. One data source for projects, operations and risk teams
HOW MUCH EFFORT/COST IS INVOLVED?
Manual method – draw a rack diagram 2 – 5 hours1. Gather inventory and positioning
2. Find Visio shapes for equipment
3. Draw the rack
Automated method with AssetGen system 10 seconds1. Tick rack for cabinet drawing
2. Visio rack diagram produced
If there are 100 racks then what does it mean?Time Engineer Cost
25 days or 16 minutes $20,000 vs $26 ($100hr)
AssetGen could automate multiple diagram updates for multiple locations every night with consistent data and symbols – No effort!
How about updating every network diagrams for every site - easy1 2 3 4 5 6 7 8 17 18 19 20 21 22 23 249 10 11 12 13 14 15 161 2 3 4 5 6 7 8 17 18 19 20 21 22 23 249 10 11 12 13 14 15 16

WHAT SHOULD DAY 3 MANAGEMENT LOOK LIKE
1. Established policies, standards and ownership
Makes it easy for engineers to plan and deliver
Simplifies roles and understanding or responsibility
2. Project / operations use common terms & formats
Common templates, naming system, labels, etc.
Easy to create, update and integrate data sets and schematics
3. Less documents / files to maintain
Use of centralised systems and internal portals
Visio diagrams, reports, Excel from infrastructure databases
4. Infrastructure knowledge is maintained by process
Changes can be efficiently delivered and managed
Less reverse engineering, more reuse of data
Documents and audit trails as evidence of control and governance
Workflow, monitoring and support systems work together
WHAT ASSETGEN CAN DELIVER
While you sleep
Changes to the IT systems and infrastructure across multiple locations are
updated into various Visio diagrams and Excel outputs overnight –
automatically!
On day 3, 4, 5, 6 and for ever…..
MAPPING NETWORKS FOR DAY 3 MADE EASIER
1. Defined naming conventions across the enterprise
2. Defined equipment, groupings and lifecycle processes
3. Replacement of Excel with database driven systems
AssetGen infrastructure database for mapping complexity
Workflow (ITIL service desk, SCM/ALM)
4. Presentation of data and views to suit information need
Views by building, floor, device, network, service, cabling, system
5. Verification processes
Manual and automated checks of both data and process
