Distributed UPS
Distributed UPS is not installed directly on the server rack, or is installed next to the server rack, resulting in all servers connected to the UPS hardware, leaving little or no space between the hardware and the server.
1. Reliability: proximity strength
For an enterprise's IT network and power supply system, the greater the distance between the server and its associated UPS, the higher the risk to the power, such as noise interference, grounding, and/or loose wiring. Since the distributed UPS is mounted directly on or near the servo rack, the distance between them is shortened, and the probability of wiring failure along the power line link can be greatly reduced.
2. easy installation and integration
Lightweight and highly maneuverable, making distributed UPS installation and movement extremely easy, making it an ideal choice for data centers that require high mobility. Highly close server racks also make distributed UPS an advantage in Ethernet connectivity.
3. Better cost control for small organizations
Since the design of the distributed UPS is not for the entire enterprise network, but only a server rack in the network, the initial prepaid expenses for purchasing this solution are much lower than the centralized UPS.
4. Disadvantages: poor management efficiency
The role of the server is such that it must be placed in front of the standby power system, allowing the UPS to take up more server rack space, thus reducing the server's available space.
Centralized UPS
The centralized support architecture consists of one or two large UPSs installed at the perimeter of the server room, at the endpoints of the entire row of servers, or at a separate location adjacent to the server. A centralized UPS is like a huge power protection network around the organization's overall network.
1. reliability
The design of centralized UPS is based on the needs of high-density server hardware. Since these hardware usually use three-phase power, the UPS is of course more durable and better, so that this type of UPS can protect both single-phase and three-phase loads.
2. stable output and increase space utilization
Centralized UPSs are typically dual-conversion architectures that operate online, providing a high-stability power curve and eliminating most power interruptions. On the other hand, the distributed UPS is designed to cope with power supply fluctuations, which means that abnormal conditions are transmitted to the terminal device. Furthermore, the UPS in the centralized backup architecture is separate from the server rack, thus freeing up valuable space for server hardware.
3. Improve the scale of the economy
In order to increase the capacity of the distributed backup architecture, data support personnel must manually add additional UPS to each server rack, which can be extremely cumbersome and inefficient in large enterprises. In addition to reducing the valuable rack space available to server hardware, this architecture also doubles the number of devices that data technicians need to monitor and repair.
4. Disadvantages: poor energy efficiency and cost issues
The use of a centralized UPS requires a large footprint and the coordination required for planning, installation, setup, testing, and commissioning is relatively cumbersome. Most companies choose to use centralized UPS and often overestimate the need. And because the company overestimates the required capacity of the centralized UPS, it wastes almost 25% of the energy.
