Most data center organisations still treat Enterprise Architecture as an IT exercise, which is why EA efforts don’t change capacity predictability, uptime stability, energy efficiency, SLA adherence, expansion timelines, or cost transparency.
Data Center EA ≠ Data Center IT.
This Director EA FAQ explains where traditional EA breaks down and how a true enterprise anatomy reveals the structure that IT alone cannot see, align, or repair.
It explains the logic of shadow anatomies, 12 data center use cases, and the One Data Center One Anatomy™ advantage.
Q1: Why do 140 IT projects ≠ Data Center Enterprise Architecture?
Myth:
Data Center EA = servers + storage + network + DCIM + cloud tooling.
Reality:
A data center enterprise operates through 15 departments (D1–D15) such as Capacity Planning, Power & Cooling, Facilities, Network Operations, Platform Operations, Security, Compliance, Customer Provisioning, SLA Management, Energy Management, Asset Management, Finance, Commercial, and Operations — each with its own P1–P6 execution cycle.
Data Center IT is only one department.
EA (IT) ≠ Enterprise Anatomy.
A project inventory cannot show how capacity strategy, power availability, cooling constraints, redundancy logic, customer SLAs, cost models, and expansion decisions align across the enterprise.
Q2. Why do so many IT projects fail to represent the data center enterprise?
Because data center IT automates only small fragments of P5 tasks, while the real operating architecture of a data center lives in P1–P4, not in the task layer.
Every data center department operates on a full P1–P6 structure:
P1 (Strategy) defines capacity growth, redundancy standards, energy strategy, and margin targets.
P2 (Processes) defines capacity planning, provisioning, change management, maintenance, incident response, and expansion execution.
P3 (System logic) defines redundancy rules, power thresholds, cooling limits, failover logic, SLA enforcement, and exception handling.
P4 (Component Spec) defines rack standards, power chains, cooling zones, redundancy tiers, contracts, and datasets.
This is the architecture (P1-P4) of the data center enterprise.
Most IT projects touch P5 only — automating selected tasks such as provisioning tickets, monitoring alerts, reporting, or billing — while P1–P4 remains fragmented, manual, or interpreted differently across teams.
The mismatch is structural:
IT systems automate tasks.
Data centers operate on capacity, resilience, and energy architecture.
Because P1–P4 was never architected:
• capacity assumptions differ across planning and operations
• redundancy rules are applied inconsistently
• power and cooling constraints are locally overridden
• SLAs are interpreted differently by teams
• expansion logic diverges from commercial commitments
• cost visibility fragments across departments
Data center IT does not fail because systems are weak. It fails because it is built on an incomplete representation of the enterprise.
Q3. What drives the high project count in the data center industry?
Data centers are constraint-heavy, asset-intensive enterprises where every change cascades across functions.
A new customer contract impacts capacity, power, cooling, network, and SLA logic.
A density change affects rack standards, cooling zones, and energy planning.
A redundancy upgrade impacts power paths, maintenance schedules, and risk posture.
An energy regulation change affects sourcing, reporting, and cost models.
An expansion decision impacts facilities, finance, operations, and commercial teams.
High project count reflects physical, energy, and SLA complexity, not IT inefficiency.
Q4. What is unique about the data center industry’s 15 Functions (D1–D15)?
Each data center organisation has a distinctive 15-function anatomy (D1–D15 × P1–P6).
Data center highlights:
D1 Capacity Planning – governs growth and utilisation logic
D3 Power & Cooling – governs availability and constraint rules
D5 Facilities – governs physical infrastructure and resilience
D7 Network Operations – governs connectivity and redundancy
D9 Platform Operations – governs uptime and incident response
D11 Energy Management – governs efficiency and sustainability
D13 SLA & Customer Operations – governs commitments and penalties
These functions generate the strongest P1–P6 drift when not aligned.
Shadow anatomies emerge when teams optimise locally instead of structurally.
Q5. What does P1–P6 look like in the data center industry?
This explains how strategy (P1) → operations (P6) breaks down.
P1 Strategy:
capacity growth, redundancy standards, energy and margin targets.
P2 Process:
planning, provisioning, change, maintenance, incident response.
P3 Logic:
redundancy rules, power thresholds, failover and SLA logic.
P4 Components:
racks, power chains, cooling zones, datasets, contracts.
P5 Implementation:
tickets, monitoring tools, dashboards, manual overrides.
P6 Operations:
facilities and ops teams applying rules differently.
Data center drift occurs when these layers no longer form one integrated sequence.
Q6. We already have extensive architecture documentation. Why redo this?
Myth:
More documentation means we understand the enterprise.
Reality:
Documentation shows parts of the data center. Enterprise Anatomy shows the data center as one integrated model.
Think of the human body.
It has 11 organ systems. Each has its own role, but none operate independently. They function as one integrated system with thousands of interdependencies.
A data center is the same.
A data center anatomy = 15 Functions (D1–D15) × 6 Perspectives (P1–P6).
Traditional documentation describes systems, layouts, standards, and SOPs separately — but never shows:
• how capacity strategy drives provisioning
• how redundancy logic affects uptime
• how energy rules impact cost and margin
• how SLAs constrain operations• where structural fragility originates
You get a library — not a model.
One Data Center One Anatomy™ collapses complexity into one integrated enterprise model.
Q7. How do we evolve from EA (IT) → EA (Departments) → One Data Center One Anatomy™?
Most organisations stop at EA = IT architecture.
The next evolution is:
Step 1:
Elevate EA (IT)Create the P1–P4 model of Data Center IT itself — IT strategy, IT processes, IT logic, IT components.
Step 2:
Create EA (Departments)Map 15 data center functions end-to-end (P1–P6).
Step 3:
Create One Data Center One Anatomy™Unify all departmental models into one enterprise anatomy governing capacity, resilience, energy, SLAs, and cost.
This is where drift stops — and operational predictability returns.
Q8. What can One Data Center One Anatomy™ do that traditional EA cannot?
Traditional EA documents systems. It cannot see that every data center function operates its own shadow anatomy.
In reality:
• capacity teams plan using one set of assumptions
• facilities enforce different resilience rules
• operations prioritise incidents differently
• energy teams optimise independently
• commercial teams commit SLAs separately
• finance models cost differently
Across sites, halls, and teams, this creates hundreds of shadow anatomies.
Traditional EA documents this fragmentation. One Data Center One Anatomy™ replaces it.
It establishes:
• one shared P1 capacity and resilience intent
• one P2 operational flow across planning and execution
• one P3 logic layer for redundancy, energy, and SLAs
• one P4 definition of assets, datasets, and standards
• aligned P5 execution• predictable P6 operations
That is something traditional EA cannot do — because it never models data centers as one integrated operating anatomy.
