AI Technical Summary

Problems solved by technology

The design also requires many batteries (one per server board), which increases maintenance costs and monitoring requirements to ensure a reliable backup power system
Finally, with a large number of batteries, the probability of failure of at least some of these batteries is greater, but the design does not provide redundancy in case of battery failure

Embodiment Construction

[0013] figure 1 An example electrical system is shown for powering several servers 40 located at a site such as a data center. A server 40 (or server computer), as used herein, is any hardware device designed to provide computing services to clients, usually in conjunction with appropriate software installed on the server. Accordingly, the techniques disclosed herein may be used to provide power to any type of hardware device that relies on electrical power from a power utility service and thus experiences the risk of occasional power interruptions.

[0014] Utility services often transmit and deliver AC power at a voltage higher than that used at the customer end. Therefore, if figure 1 As shown in , a site transformer 10 receives AC power from utility service and steps down the voltage for use at the site. The site transformer is coupled to several power distribution units 30, which distribute electrical power throughout the site. In a typical industrial deployment, such...

Abstract

The need for an uninterrupted power supply (UPS) in a data center is obviated by tying a DC voltage from a backup power source directly to the motherboards of multiple servers in the data center. AC power received from a power utility service is converted into a lower voltage by a site transformer and then provided to one or more power distribution units at a site. The power distribution units supply power to a plurality of servers, which include power supplies that convert the AC electrical power to DC electrical power for use by the servers' motherboards. In the event of a failure of power from the utility service, the backup power source provides DC electrical power to the motherboards, e.g., for sufficient time to start up a generator to provide power in place of the utility service.

Description

technical field [0001] The present invention relates generally to power electronics and, more particularly, to providing backup power to multiple servers and / or other critical electrical equipment in a data center. Background technique [0002] Organizations often employ data centers to manage their data processing and other computing needs. Data centers typically house many racks of servers that together perform processing tasks that a single machine cannot. The role of a data center is often critical to an institution, and downtime of a data center can have serious consequences for the institution and others who depend on the data center. Because power failures are common, data centers use power backup systems to handle interruptions in power supply from utility services that would otherwise result in downtime. [0003] One type of power backup system designed to provide emergency power to computing resources is known as an uninterruptible power supply (UPS). In a typic...
