How To Select UPS For Server Room

Data centers and server room environments are not immune to the revolutionary tidal wave of “Big Data.” This new generation of connected devices (connected in that they can reach their status) is responsible for producing this big data within the server room and data center environments. Collecting this data, and then analyzing it will have a significant impact on how server rooms function and how systems administrators figure out which features of their server rooms need improvement. Small and medium-sized server rooms need high-quality, productive, and secure backup when the power fails or drops to an unacceptable level. IT equipment is extremely sensitive to electrical irregularities, that is why it is significant to protect it with a well-chosen UPS for the server room

For server racks at server rooms, rack mount UPS systems are very common. Though, rack mount systems have limited battery capacity to carry the load for a long period. If the facility has no backup generator then a stand-alone system would operate better as it normally has a large internal space for extra batteries. For IT applications it is a common method for UPS systems to operate at approximately 50% (75% maximum) of their entire capacity. To size, a UPS, just simply add power ratings of the equipment together then double it up. This will give you the capacity of the UPS with sufficient headroom. Great quality IT equipment would create a high inrush current during start-ups. Hence, UPS needs to have enough capacity to control that. Nevertheless, to size the battery banks you’ll require to use the entire power rating of the load multiply by 50%, then work out how many and what type of batteries will be required to achieve the runtime. The purpose of doing this is not all equipment will carry full power during normal conditions. The continuous load usually will be less than 50% (20% even) of the rated power. 

How to make sure that you have enough backup runtime?

When sizing a battery set for a UPS the main factors to consider are-

Site power records, and, the duration of previous mains power supply malfunctions

Critical load capacities

If there is a secured standby generator on site

The length of time needed for load backup 

The convenient environment, for example, space, temperature, and humidity

Expense versus space necessities for longer runtime operations

When valuing UPSs, we normally provide comprehensive runtime data for the UPS System within the range of load levels it can carry. Most UPS have expandability capacity, so an external battery cabinet can be attached to increase runtime. Some of our UPS have particular energy share sockets that enable load backup to increase the battery runtime ready for more critical loads- alternatively, emergency loads that are normally not power when mains is present can be activated. Load backup is a common method to handle possible downtime on networks where there are various servers or equipment clusters that require protection. 

Line-interactive UPS are less expensive than on-line UPS systems, but they give less protection than on-line UPS systems. Line Interactive UPS operates similarly to an Offline UPS, with the addition of a built-in Automatic Voltage Stabiliser (AVS). The AVS guarantees the output voltage prevails within a pre-defined voltage window regardless of any voltage changes on the mains input supply. Most Line Interactive UPS will provide a modified sinewave (more commonly identified as a ‘step-wave’) whereas on-line UPS will provide a sinewave output. Line Interactive UPS are typically used in smaller, less critical applications, such as PCs, telephone systems, non-critical networking devices, and modest motor loads.
