5G is here, are data centers ready?


With the imminent freezing of the 5G standard (R15), the commercial use of 5G network equipment and the release of 5G mobile phones, 5G has become one of the hot topics in the streets, and people are full of expectations for the application prospects of 5G.


And what does all this have to do with the data center?


In order to meet the requirements of “large bandwidth, low latency, and wide connectivity” for 5G services, the 5G network adopts a cloud-based architecture based on data centers to realize network slicing, support the separation of control plane and user plane, and improve resource elasticity and utilization. Efficiency, and through the sinking of the data center to carry MEC (edge ​​computing) services, the data center will become the cornerstone of the 5G network.


Since data centers are so important, how are 5G-oriented data centers planned?


Based on the needs of 5G services, operators’ data centers in the province are generally divided into a three-tier architecture, including regional DCs, local DCs, and edge DCs, of which:


▲Data center layered architecture


The regional DC is usually a large data center (including the provincial hub computer room), which mainly carries the provincial control plane network elements and media plane network elements;


The local DC is usually a small and medium-sized data center (including a city hub computer room), which carries user plane services, as well as city-level control plane network elements and centralized media plane network elements;


Edge DCs are usually small data centers (including aggregation equipment rooms), which mainly carry media plane data and private line user access to meet ultra-low latency or ultra-large capacity requirements.


Based on the planning of the 5G data center, does the operator’s existing equipment room meet the requirements?


At present, the operator’s computer room mainly carries communication equipment, and the power consumption of communication equipment is smaller than that of IT servers. If an IT server is replaced or newly added, it is necessary to first consider whether the power supply of the computer room is sufficient and whether the air conditioning and refrigeration meet the requirements. In addition, it is necessary to consider whether the load-bearing of the computer room, the height of the lower floor of the beam, and the area of ​​the computer room are suitable for transformation into a data center.


How to transform a telecommunications room into a data center?


To determine whether a telecommunications room is suitable for transformation into a data center, and how to transform it, the following issues need to be considered:


▲Schematic diagram of the data center renovation plan


  1. Remaining power: If the remaining power is not enough to support the power consumption of the IT equipment, the power distribution transformation will be carried out. If new commercial power cannot be introduced, the computer room is not suitable for data center transformation.


  1. Energy efficiency improvement: Modular cabinets are used to improve refrigeration efficiency through closed cold aisles; fluorine pumps are used for natural cooling air conditioners, which use natural cold air for refrigeration to reduce the frequency of use of air conditioner compressors.


  1. Floor height and load-bearing of the computer room: If the height of the lower floor of the beam is less than 3.5 meters, then the computer room is not suitable for transformation into a data center. If the load-bearing capacity is less than 600kg/square meter, the load-bearing renovation of the house can be considered, and the load-bearing capacity of the house can be increased to 600. -1000kg/square meter.


  1. Optimization of computer room space: Modular UPS (such as Huawei Modular UPS) can be used indoors, covering an area of ​​1.2 square meters, which saves 40% of the floor space compared to traditional UPS; centralized condenser is used outdoors to reduce the footprint of outdoor units more than 30% of the area.


Based on industry-leading 5G technology and extensive data center integration experience, Huawei has leading solutions in the field of 5G-oriented data center planning and transformation. The rapid advancement of 5G pilots for operators.


5G has come, data center resources can be prepared now.
