Qingdao Unicom, a subsidiary of China Unicom (Shandong), connects major cities, such as Beijing, Shanghai, and Guangzhou. Located near two submarine cable systems and three submarine optical cables, including the Trans-Pacific Express (TPE) and East Asia Crossings (EAC), it is well-placed to offer data center services to several large Internet companies.
To meet growing demand, Qingdao Unicom built a new data center. The center, China Unicom’s largest, is 2,229.411 square feet (21,313 square meters) and accommodates 25 Internet data centers, including one core, 24 V.I.P. rooms, and 3,500 cabinets.
Because of the size, complexity, and time restrictions, Huawei faced several big challenges with this project.
Huawei followed an aggressive two-year, two-phase schedule to get up and running quickly. Phase 1 went online in August 2012 and Phase 2 went online in August 2013.
Large project scale
To take advantage of Qingdao’s rapidly growing business opportunities, Huawei deployed 3,500 cabinets; 750 in Phase 1 and 2,750 in Phase 2.
The data center uses 2N redundancy for power supply modules and N+1 redundancy for cooling systems. It also meets Tier 3 design standards.
To accommodate demanding end-customers, the solution allows Qingdao Unicom to customize individual power, cabinet, and Power Distribution Unit (PDU) needs easily.
Huawei designed a solution specifically for Qingdao Unicom.
Qingdao Unicom had three construction options:
Qingdao chose to convert the old factory to expedite service rollout and reduce initial investment costs.
Huawei placed air-cooled chillers on the roof to maximize space usage.
Building reconstruction and hardening
Because the building is located in an active fault zone, it was upgraded to Chinese data center standards for earthquake resistance and floor load capacity.
Power supply and distribution
An optimized Tier 3 2N architecture:
Huawei chose the most appropriate water-side free cooling system after thoroughly analyzing local climate data, considering the investment budget, and Power Usage Effectiveness (PUE).
Based on end-customer requirements for 3 kW to 4 kW cabinets, Huawei used a Computational Fluid Dynamics (CFD) simulation to choose under-floor air ventilation plus cold aisle containment.
Egress network optimization
Huawei analyzed traffic models to plan routing and increase backbone network bandwidth from 40 Gbit/s to 320 Gbit/s.
Huawei performed scenario-based performance analysis to meet end-customer business requirements. Customization included:
Huawei provides one-stop planning, design, integration, and delivery services to bring Qingdao online quickly and provide end-customers with innovative solutions. With the new network advantages at the backbone’s core node network, Qingdao was sold out even before the data center came online.
Huawei’s world-class team provided a range of services:
Plus, more than 20 Huawei engineers supported on-site delivery, ensured quality, and delivered the data center efficiently.
Huawei’s solution allows Qingdao Unicom to:
