Data Center (Server Room) Procurement Plan & Structure — Shenzhou Cables
A practical guide for designing, sourcing, and validating a resilient, scalable data room (Tier II–III)
This document presents a complete procurement strategy and a reference structure for a modern data room. It focuses on standardized racks, dual‑path power, hot/cold aisle containment, structured cabling (single‑mode & OM4), and monitoring for uptime. The plan is aligned with common industry practices (TIA‑942, ISO/IEC 11801) and leverages Shenzhou Cables’ fiber cabling portfolio.
Figure 1. Data hall hot/cold aisle layout with CRAC/CRAH (schematic).
• Hot/cold aisle or containment; blanking panels and brush grommets to reduce bypass air
• CRAC/CRAH sizing by heat load; N+1 redundancy; raised‑floor optional for under‑floor air delivery
• Overhead ladder racks; separation of power and data
• Core/Spine → Aggregation/Leaf → Access/ToR; redundant uplinks; MLAG/VPC where applicable
• OOB/management network physically separated; dedicated KVM/IPMI
• Structured fiber: MTP trunks to cassettes; LC patch cords to servers; standard lengths and polarity mapping
Figure 2. Core/Aggregation/Access network blocks with ToR.
• 42U/45U racks with front/rear cable managers; rails and grounding kits
• MPO/MTP trunk cables (OM4/SM) to modular cassettes; LC/SC patch cords to endpoints
• ODF/patch panels at MMR/IDF; color‑coded labeling for SM vs MM
• Copper: Cat6A for management and specific workloads (PoE, OOB)
Figure 3. 42U rack elevation with ToR switch, servers, and UPS/BBU location.
• Dual A/B power feeds from UPS to PDUs; selective transfer switches (STS) as required
• Proper bonding to grounding grid; surge protection
• Battery autonomy sized to ride‑through generator start; graceful shutdown policies
Figure 4. Dual‑path power from Utility/Gen to UPS → PDU → racks (A/B feeds).
• Environmental: temperature, humidity, differential pressure, leak detection
• Fire: early smoke detection, clean‑agent suppression (e.g., FK‑5‑1‑12)
• Access Control: zones with badges/biometrics; CCTV and audit logging
Figure 5. Environmental sensors and security zoning (illustrative).
• Single‑mode (G.652.D/G.657.A1) for longer interconnects/MMR; OM4 MM for ToR links
• Polarity Method B or equivalent; document trunks/cassettes; test at 850/1300 nm (MM) and 1310/1550 nm (SM)
Figure 6. ODF → MTP trunks → cassettes → LC fan‑out towards ToR.

Factory: routine/type tests for cables and cassettes; connector IL ≤0.3 dB (LC), ORL ≥55 dB (APC). Site: pathway inspection; OTDR 1310/1550 (SM) and 850/1300 (MM); OLTS certification per link; labeling/audit; power failover test (A/B feed, UPS runtime), hot/cold aisle pressure check.
Export‑grade crates and reels; moisture barrier; impact indicators; QR‑coded labels with BOM mapping; staggered deliveries aligned to fit‑out phases; returnable reels when feasible.
• Lead‑time volatility → lock forecast; safety stock for MTP trunks and cassettes
• Workface clashes → weekly coordination with GC/MEP; pre‑pull approvals
• Heat load creep → scalable cooling blocks; capacity headroom ≥20%
• Cable damage → protected pathways; trained crews; inspection hold points
