Features and Benefits

Key Features
1. Fault Tolerant Data Center Infrastructure

FDC2 builds on the robust foundation of FDC1 to offer a Tier IV ready infrastructure, modular design and hybrid tiering model to give clients the highest level of reliability and agility.

  • Fault tolerance design with no single point of failure
  • Compartmentalization of critical facility systems and distribution paths
  • Dual utility power
  • N+Catcher continuous rating generator system
  • N+Catcher UPS systems with 15 minutes battery backup at full load
  • N+1 water-cooled chiller system¹ with 42 minutes cooling battery (chilled water storage) at full load for continuous cooling, PLC controlled
  • 2N fuel supply system, PLC controlled
  • 24 hours of diesel storage and condensing water storage at full load
  • Water-side free cooling system
2. Innovative Technologies For Optimizing Total Cost of Ownership (TCO)

FDC2 features some advanced data center technologies designed to help clients optimize total cost of ownership in the long term.

High Density Design

Industry leading ultra-high density data center design which supports installation of 54U rack with maximum rack height at 2.6 metres, and power density up to 24kVA per rack.

Cooling Wall

FDC2 unique front-flow cooling design with hot aisle containment improves overall cooling efficiency for better PUE, supports higher power density per rack, and is more suitable for the dynamic load under virtualized IT environment.

Cooling Battery

An innovative stratified thermal energy storage system with 3,600,000 litres of chilled water which provides 42min of chilled water backup to maintain stable environmental condition, and allows operating temperature to rise without the risk of thermal runaway.

Smart Lighting System

Cost-efficient LED lighting running on ultra low voltage with motion and temperature sensing functions. Integrate with security and life safety systems to enhance security and safety level.

Water-side Economization

When wet bulb temperature is lower than 10.5ºC, the chillers will be shut down and the cooling system uses the cooling towers for direct cooling. Together with the Cooling Wall, FDC2 can achieve a market-leading annualized PUE of below 1.5 at full load condition.

3. Enhanced Service Visibility

To help our customers embark on their business transformation journey, FDC2 adopts a digitalization and big data approach for end-to-end data center lifecycle management. Being the pioneer to adopt BIM² in design, construction and commissioning management for data center project, FDC2 further integrates the BIM information and data with the in-house Data Center Management System (DCMS) to offer an end-to-end solution for life cycle management of all critical facilities in the data center. Customers can realize the benefits through our customer portal “Virtual Data Center”, to gain enhanced visibility to real-time and historical data center performance to enable informative decision making as well as strategy planning.

4. Cascade SLAs For Better Service Guarantee

FDC2 introduces a brand new SLA model that goes beyond traditional SLAs on power and cooling, and extends to cover connectivity, security and response time - in total offering more comprehensive risk management and guaranteed compensation for our clients.

5. Faster Business Communication and Innovation

Riding on NTT Communications’ Tier 1 network infrastructure co-located with FDC2, customers can enjoy exceptional ultra-low latency and reliable global connectivity to meet their needs for fast and “frictionless” business communications.

6. Robust Physical Security

Eight tiers of physical security measures with digital sign-in process ensure that our client’s mission-critical assets are in safe hands. Physical security controls at the site, building and lobby entrances, in the lifts, at floor and ICT hall mantraps right down to the cage and cabin ensures only the right approved personnel has access to your servers.

¹ Optional upgrade to Tier IV
² BIM (Building Information Modeling) is an intelligent model-based process that provides insight to help you plan, design, construct, commission and manage buildings and infrastructure.
