China Unicom-Guizhou Chooses Huawei’s Modular Data Center Infrastructure

22-09-2016 00:00:00


China is expected to account for 20 percent of the world’s data capacity by 2020, creating a massive market for economic transformation. The government of Guizhou Province in an effort to popularize cloud computing in 2012 authorized the construction on Guian New District, a 1,795-square-kilometer area in Southwest China designated as an economic driver and a model for eco-friendly development. Telecom company China Unicom, along with China Telecom and China Mobile, decided in 2013 to set up a cloud data center in Guizhou, with a total initial investment of USD 1.2 billion.


Faced with endless amounts of data, governments and enterprises are particularly concerned about the rapid development of the mobile Internet market, such as ‘smart’ government, ‘smart’ tourism, and other Smart City applications, as well as the commercial use of Virtual Reality (VR), Artificial Intelligence (AI), and robotics. High-standard cloud data centers are required to transmit such massive amounts of data.
The Big Data industry has been a focus in Guizhou in recent years. The goals of China Unicom’s Guian Cloud Data Center project included a short construction period to adapt to the quickly expanding cloud data center market and efforts to reduce energy consumption in response to a national call for building ‘green’ data centers.


After careful analysis of China Unicom-Guizhou’s requirements, Huawei proposed its Modular Data Center (MDC) infrastructure, characterized by reliability, efficiency, and simplicity. The infrastructure consists of the following:
  • Huawei’s reliable T4+ modular Uninterrupted Power Supply (USP)
  • Cabinets
  • Power distribution
  • Air conditioning
  • Cabling components
All components can be centrally controlled, making each micro-module a self-contained unit. The infrastructure features:

  • Standardized devices, modular architecture, and on-demand deployment Integrated power supply and distribution
  • 1 to 2 IT racks to save space
  • Remote and local intelligent management, and mobile O&M
  • Closely coupled cooling and efficient power system
  • Aisle containment and separated hot and cold air to eliminate hotspots
  • Integrated high efficiency UPS power system
  • Dehumidifying at low-load rate down to 10 percent for safe operation of IT equipment
  • Excellent environment adaptability and stable operations under extreme conditions
  • Pre-alarm of circuit breaker terminal with temperature monitoring
  • Batteries with auto-shutdown for fire protection
  • Power-off rate reduced by 50 percent
Fast Deployment and Simple Expansion:
  • Huawei’s MDC is modularized and prefabricated, saving more than 30 percent in deployment time. The modular architecture enables flexible future capacity and density expansion of IT devices.
Efficient Energy Consumption:
  • Huawei’s green data centers use in-row air conditioning and containment aisle technology, particularly in-row horizontal flow and closely coupled cooling to reduce energy consumption
  • The containment aisle isolates hot air from cold air. The cooling efficiency is significantly increased, while the Power Usage Efficiency (PUE) and Operating Expenditure (Opex) is lowered. The lightweight and efficient Huawei UPS5000-E saves on electricity costs for Guizhou Unicom, an excellent response to the national movement for energy conservation.
Security and Reliability:
  • The construction of Guian cloud green data center conforms to international T3+ standard. Using a full-modular design, each module supports hot swapping to significantly reduce maintenance time and lower the risk of service interruption.


The China Unicom Guian Cloud Data Center is now largely operational and has the core capabilities to carry Internet+ projects. The data center can provide cloud computing, cloud storage, disaster recovery backup, and Internet Data Center (IDC) leasing.

“We brought down the PUE of the project to 1.3,” said Zhou Xuhua, Technical Director of Huawei’s Data Center Projects. “Within 6 months, we delivered 62 high-quality micro-modules to help our customers launch their services.”

“The most important thing is that China Unicom deployed a leading-edge modular data center in China,” added Chen Jinghua, Vice General Manager of Guizhou Unicom Cloud Data Co., Ltd. “We adopted Huawei’s modular design and deployment scheme. Prefabricated modules and solutions are used to facilitate the whole construction process. The micro-modules we adopted reduce costs and shorten the construction duration significantly compared with traditional data centers.”
