This is an important and broad topic in the digital infrastructure industry. Technical consulting for Data Centers (DC) covers multiple layers of expertise — from initial design to operation and optimization. Let me present it in a structured way.
Detailed breakdown of each area
1. Strategy consulting & master planning
This is the first and most critical step, typically for investors starting from scratch. It includes:
- Site selection: Evaluate construction location — geology, flood risk, distance to power substations, telecom infrastructure, surrounding population density.
- Feasibility study: Analyze technical, financial, and legal feasibility (urban planning compliance, construction density).
- Tier classification: Define redundancy level (Tier I–IV) aligned with target customer SLA.
- Master plan: Develop phased investment plan — modular build, scalable expansion, optimized cash flow.
2. Engineering system design
The most specialized area, requiring hands-on experience:
Electrical systems:
- Design HV/MV/LV power systems, load calculation, redundancy (N+1 / 2N)
- UPS selection (online double conversion, Li-ion vs VRLA), intelligent PDU
- Generator systems (Generator + ATS/AMF), transfer time
- Earthing & bonding, EMC, lightning protection
Cooling systems:
- CRAC/CRAH capacity calculation, hot aisle/cold aisle containment
- Chiller plant, cooling tower, free cooling design
- Liquid cooling for AI racks: CDU, rear-door heat exchanger, direct liquid cooling (DLC)
- Immersion cooling (single-phase / two-phase) for workloads >40kW/rack
- ASHRAE wet-bulb calculation, PUE target
Civil & MEP:
- Floor loading, raised floor vs on-slab
- Fire suppression (FM200, Novec 1230, inert gas, aspirating smoke detection)
- Structured cabling, containment systems, blanking panels
3. Standards & compliance
Consulting helps clients understand and properly apply standards:
- Uptime Institute Tier: Tier I → IV, not just certification but a design methodology
- ANSI/TIA-942: Rating 1–4 classification, detailed infrastructure checklist
- ASHRAE TC9.9: Operating temperature and humidity, A1–A4 equipment classes
- IEC 62443: Industrial control system security
- TCVN 9250:2012: Vietnam standard for Data Centers (often used alongside ANSI/TIA-942)
4. AI & HPC-Ready Data Center consulting
This is a rapidly growing field in Vietnam and Southeast Asia, requiring specialized knowledge:
- Power density: Traditional 3–8 kW/rack → AI workloads 20–100+ kW/rack
- Power infrastructure: Busway instead of cable tray, 400V distribution, intelligent 3-phase PDU
- Cooling redesign: Air cooling is insufficient → liquid cooling (DLC, immersion) is required
- Network topology: Spine-leaf architecture, 100G/400G fabric, RoCE for GPU-to-GPU communication
- Resilience: GPU cluster failure domains, fat-tree topology, RDMA
- Investor consulting: Compare CAPEX/OPEX across cooling solutions, ROI modeling
5. Operations & Maintenance (O&M) consulting
Even a Tier IV design can fail with poor operations. Includes:
- SOP/MOP/EOP: Develop standard operating procedures, maintenance plans, incident handling
- DCIM: Consulting on infrastructure management software (capacity, power, thermal)
- BMS integration: Integrate BMS with DCIM, alarm management
- DRP/BCP: Disaster recovery and business continuity planning, regular testing (tabletop, live drills)
- Commissioning & testing: PTAC, integrated system testing following Uptime Institute guidelines
6. Assessment & audit of existing infrastructure
For operational data centers needing improvement:
- Gap analysis: Compare current state with target standards (Tier, ANSI/TIA-942)
- PUE audit: Measure actual performance, identify energy losses, recommend improvements
- Capacity planning: Forecast IT load growth, identify upgrade points
- Retrofit recommendation: Suggest phased upgrades without service disruption
7. Technical training & knowledge transfer
This is especially important in Vietnam due to the shortage of internationally certified professionals:
- Training based on BICSI RCDD, DCDC, RTPM
- Training based on Uptime Institute ATD (Accredited Tier Designer), ATP, AOS, ASA
- In-house training for client O&M teams
- Technical seminars for engineering communities (e.g., BICSI Vietnam Chapter, VDCC)
