What kind of UPS does a data center need?
First, it must be acknowledged that there are still significant differences in the understanding and application of UPS across different industries. The application of various solutions also varies from person to person, and there is no unified standard. However, under the premise of ensuring reliable power supply, the author believes that future data centers will place higher demands on power supply and distribution systems in the following aspects.
1) The first is “fast”, that is, rapid construction and rapid expansion.
Currently, the modular concept has been widely accepted in data center construction. Both modular data centers and containerized data centers embody this concept. Modular UPS systems also conform to this principle. From the perspective of overall deployment speed, there isn’t a significant difference between modular and tower UPS systems. However, in terms of future expansion and initial investment, modularity offers significant advantages. First, the on-demand power modules better meet the needs of business development. Especially for internet companies with an average lifespan of only 3 to 5 years, those who can complete deployment and expansion sooner can win customers and capture market share earlier. Compared to the one to two weeks installation time of traditional tower UPS systems, modular UPS systems can be expanded in just a few minutes. Second, increasingly fierce business competition, a volatile market environment, and uncertainties about future development require CEOs to find the optimal balance between long-term planning and initial investment. Modular structures only require reserving appropriate space, eliminating the need for a one-time investment. Future investments can be made in batches according to business development, significantly reducing operational risks. For customers, whether building their own or leasing, modular UPS systems are more suitable for the company’s long-term development.
2) The second is “ease”, that is, ease of use and high availability.
Compared to the complex Tier 4 architecture and 2N systems designed to ensure reliability in traditional data centers, seemingly “unbelievable” solutions such as bypass mode and direct mains power supply + UPS backup are being adopted by internet giants. It is precisely the implementation of virtualization technology that has enabled internet companies to shift their focus from simply pursuing power supply reliability to prioritizing availability, represented by rapid maintenance.
Therefore, UPS systems must be as easy to maintain as IT equipment. This places two requirements on UPS systems: 1. Failures should not affect business operations, i.e., they should not disrupt normal power supply; 2. Maintenance should be convenient after a failure, ideally allowing maintenance personnel to perform maintenance themselves without contacting the manufacturer. Clearly, modular UPS systems best meet these requirements. Both AC modular UPS systems and DC modular UPS systems (high-voltage DC) demonstrate higher availability and ease of maintenance.
