| 20110018342 | DIRECT TIE-IN OF A COMMON BACKUP POWER SOURCE TO MOTHERBOARDS IN A SERVER SYSTEM - 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. | 01-27-2011 |
| 20110128699 | COOLING SERVERS IN A DATA CENTER USING FANS EXTERNAL TO SERVERS - To avoid the need to operate in-chassis fans to cool rack-mounted servers in a data center, the data center is arranged into a hot aisle and a cold aisle. The cold aisle is adjacent to a first side of the rack mounted servers and receives cold air from a cold air supply unit. The hot aisle is adjacent to a second side of the rack-mounted servers and has a lower pressure than the cold aisle. Because of the pressure difference between the cold aisle and the hot aisle, cold air flows through the rack-mounted servers, cooling electronic equipment therein, into the hot aisle. Control systems are used to obtain sufficient cooling. | 06-02-2011 |
| 20120041600 | Load Balancing Tasks in a Data Center Based on Pressure Differential Needed for Cooling Servers - In a data center that cools servers using an airflow from a central fan, rather than individual server fans, the cooling needs for each server are met by creating a sufficient pressure differential across each server. Because the pressure differential is the same for all of the servers, it is desirable to operate the data center such that each server needs the same pressure differential for proper cooling. Accordingly, a load balancer assigns tasks to the servers based on the known cooling needs of each server in order to balance the pressure differential needed to cool the server. This information may also be sent to the central fan to ensure that a sufficient pressure is created by the fan. Determining the cooling needs beforehand avoids spikes in server temperature, thereby enabling the servers to operate safely at a temperature closer to their maximum rated temperatures. | 02-16-2012 |
