Embodiment Construction

[0014] Figure 1A and 1B is an example of a mobile rack system. Figure 1A A server system 100 is depicted, which may include a mobile rack 110 having wheels 112, a plurality of shelves 114 for holding components, a rack monitoring unit (RMU) 118 for monitoring the status of features of the rack, a plurality of rectifiers 124, battery power supply 126, battery boxes 128, 129 and a plurality of computing components 130-132. Figure 1B is not a shelf 114 Figure 1A An example of rack 110. exist Figure 1B , it can be seen that the rack 100 includes the main bus bar 134 .

[0015] Server system 100 supplies power to computing components from a power source. For example, although not shown in the figures, each shelf of the rack may be connected to a power source, such as an AC or DC power source, through the main bus bar 134 . A main bus bar 134 may also be connected to each shelf of the rack to provide power and data to components or battery boxes.

Abstract

Computing devices (130-132) are associated with circuits for sharing and distributing backup power. During normal operating conditions, the main bus (134) provides power to each computing device in the rack (110) via the main power bus (455) of the corresponding circuit (400). In the event of an AC power outage, the main power bus is deactivated and the circuit's backup power path (460) is activated. The backup circuit is provided to the device from the circuit's battery (405) via a backup power path. A shared power path (465) is also activated in the circuit so that backup power can be provided from the battery to the main bus. By providing backup power to the main bus, other computing devices in the rack that do not have sufficient backup power can receive backup power from the main bus until AC power is restored.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation of US Patent Application No. 13 / 705,609 filed December 5, 2012, the entire disclosure of which is hereby incorporated by reference. Background technique [0003] Companies operating large-scale computing systems invest enormous sums of money to build and maintain the hardware necessary to house the computing systems. For example, some computing systems may include multiple racks for holding computing equipment, such as hard drives or entire servers. These racks are usually very expensive to purchase and come in only a few standardized sizes. Each rack or group of racks is typically provided with a backup power architecture to power computing equipment in the event of an AC power failure. Backup power architectures may include co-located battery packs, which may affect power sharing efficiency. Contents of the invention [0004] The present disclosure relates to a rack system having...
