How to Choose a High Performance UPS for Your Data Center

All data center managers appreciate the need to maintain 100% availability and avoid any form of downtime. Downtimes are so costly in mission critical data centers that everything possible should be done to prevent them. That is why the choice of uninterruptible power supply (UPS) must be handled with careful thought and planning. In order to choose the best UPS for your data center, here are some of the most important features to consider.

1. Ability to Offer Full Load ProtectionChoose a UPS model that has the capacity to withstand multiple power or environmental events without switching to battery backup. The UPS should have a continuous-duty static switch that gives maximum fault clearance when there is a downstream fault or extreme overload. Look out for redundant fans that will allow the unit to tolerate more than one fan failure. The UPS should also keep the system protected when you start up a relatively large power distribution unit, and it should have a high withstand rating that permits it to remain online when there is a serious short circuit or overload condition.
2. User-friendlinessA well designed UPS will be easy to use by all your data center employees. Look for the capacity to receive input from different utility sources including the power grid and a standby generator. Preferably, its display should be large, user-friendly and informative. The display should show system parameters, help screens, and alarm status. The UPS should also comply with the FCC standards for conducted and radiated noise. This means it should not interfere with wireless or wired communication equipment. To ensure maximum availability, the UPS should be backed up by factory-trained expert support personnel.
3. Provision of Capacity on DemandTake advantage of the new UPS technologies that offer a more scalable design to accommodate both current and future capacity requirements. If you need this type of advanced power system design, you should be looking for Eaton 9395 UPS or a similar model that offers capacity-on-demand through innovative software. This allows you to increase the capacity of the UPS without installing additional hardware. So you can purchase a unit that can be scaled up to larger capacity as your demand increases.

4. Energy EfficiencyWith the increasing pressure to operate in an energy efficient environment, it is vital to choose a UPS that is environmentally-friendly. Studies have shown that a double-conversion UPS model provides greater energy efficiency than the standby or line-interactive model. Although the initial cost of the double-conversion model is higher, the additional efficiency it offers can reduce the costs of operating the data center. This cost reduction will encourage data center managers who are looking for Eaton 9395 UPS and other double conversion power system backup models to acquire systems that will provide long-term financial benefits.

ConclusionChoosing the right UPS for your data center will improve availability, scalability and efficiency of the entire system. In order to select the best UPS for your facility, you should ensure that the UPS is user-friendly, operates efficiently, and offers full protection for all your servers. As much as possible opt for a system that can be scaled up without additional hardware modules.
