2010 APAC Data Center Market Research on Electrical Infrastructure An End-user Perspective
Frost & Sullivan, Dec 2010, Pages: 69
Lithium ion UPS Popular with Small Data Centers but Large and Medium Data Centers Opt for Fuel Cell UPS
Observations reveal that 2U servers are widely adopted in data centers. Almost half of the data centers are located on the first floor. Roughly one-third of data centers have 26 to 50 of their IT equipment mounted. The small- and medium-size data centers require 4-5kW per rack, whereas large data centers require 6-10 KVA per rack. In terms of power requirements per row, one-third of small data centers require 6-10 KVA per row, while the largest proportion of medium and large data centers requires 11-20 KVA per row (39 percent and 50 percent, respectively). “Concerning uninterruptible power supply (UPS), the largest proportion of medium and large data centers uses a fuel cell UPS system,” notes the analyst of this research service. “On the other hand, small data centers have displayed a preference for lithium ion UPS systems.” Data centers experience roughly eight power outages each year on an average, with the outage lasting nearly 38 minutes. Thus, the average data center faces approximately 290 minutes of downtime every year. The most important criteria for UPS are maintenance, lifespan, and up-front pricing, and these are expected to remain relevant over the next five years.
In precision air conditioning (PAC) systems, the most popularly used PAC system is free cooling. Three of ten data centers have a PAC system that uses 501-1000 kW. Factors, such as size/architecture, cooling method, and number of racks, which influence the PAC purchase decision process, are similar for chilled water, dual fluid, and free cooling PAC. There has been a growing demand for hybrid cooling (dual fluid), as data centers tend to run extended hours and there is a need for a redundancy system.
The technology of submersion cooling was introduced in 2009, and it couples low cost and low energy usage with high effectiveness. This cooling solution runs dielectric fluid not only on racks but also on servers without utilization of chillers and small generators. It offers smart system monitoring with fully redundant cooling system. In addition to providing fixed-speed compressors that enable higher efficiency and lower cost, manufacturers in this space are offering variable-speed compressors such as drives or softstarters. “The focus on energy efficiency is eroding the significance of new cooling technology,” says the analyst. “However, comfort cooling is a minimal threat as it does not resolve the heating problems faced by data centers.”
This Frost & Sullivan research service titled 2010 APAC Data Center Market Research on Electrical Infrastructure An End-user Perspective provides an overview of the data center market, determining the size, type, location, efficiency level, as well as number and type of servers. The study also identifies prominent power equipment suppliers and examines purchase behavior.
