Critical Infrastructure Design
Meet the most demanding requirements for business continuity and network redundancy against natural disasters
- 5-layer redundancy:
Grid-to-rack power distribution (500kV → 275kV → 154kV → 66kV → 6.6kV) - Backup:
Dual 66kV feeds + on-site generators (dedicated fuel tank with disaster-response supply contracts) - Priority restoration:
Government-designated for rapid power recovery (minimal outage risk)
- Centralized water cooling + 5,000m³ thermal energy storage (chilled to 4°C using off-peak electricity)
- Dual-loop chilled water pipes + heat recovery chillers
- Emergency water reserves for cooling towers
- Foundation:
Built on solid “Tokyo Layer” diluvium bedrock (34m below surface), eliminating liquefaction risk - Seismic isolation:
– 180 shock-absorbing units (60cm displacement capacity)
– IT equipment isolated from ground motion (311 earthquake displacement: 9cm; zero damage) - Flood/tsunami defense:
Elevation T.P. +8.00m (exceeding Tokyo Bay’s worst-case tsunami projection of T.P. +4.00m) - Proximity to Ariake-no-Oka Disaster Center (<2km), ensuring access to government emergency resources
- 3 diverse entry points + multiple MDF rooms + fully redundant cabling
- Global connectivity hub:
Hosts 4 major IX nodes (JPIX/BBIX/JPNAP/KINX) and international submarine cable access - Underground deep-tunnel conduits (disaster-resistant) + inter-DC links (e.g., CC1-CC2)
For More Details
6-tier physical security:
- 24/7 guards + luggage screening
- ID/biometrics + security gates
(tiered per-zone access) - Individual cabinet locks
Energy efficiency
- High-efficiency transformers/UPS/centrifugal chillers + winter free-cooling
- Seasonal A/C optimization (higher summer, lower winter temps) + shared facility shutdowns
24/7 monitoring
- Building-wide surveillance
Independent blocks:
- Three isolated operational blocks (A/B/C) with redundant power/cooling/network (each operable standalone)
Disaster preparedness
