The disclosure generally relates to delay systems, and particularly relates to a delay system applied to a server.
A blade server may have a power supply unit, a plurality of servers, and a plurality of other loads, such as fans. The power supply unit is connected to the plurality of servers and the plurality of loads, for providing power for the servers and the plurality of loads.
Many aspects of the embodiments herein can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings, in which like reference numerals indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.” The references “a plurality of” and “a number of” mean “at least two.” In the following disclosure the term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected.
In general, the word “module,” as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language such as Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as in an erasable-programmable read-only memory (EPROM). The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable media are compact discs (CDs), digital versatile discs (DVDs), Blu-Ray discs, Flash memory, and hard disk drives.
The external power supply unit 300 includes a power managing sub-unit 310, and a converting board 320 coupled to the power managing sub-unit 310. The converting board 320 is connected to the load 400 and the plurality of servers 500. The power managing sub-unit 310 supplies power for the servers 500 and the load 400. The load 400 can be fans or other loads.
Each server 500 further includes a data processing unit 510, a connecting unit 520, and a protecting part 530. The connecting unit 520 is coupled to the converting board 320 and the delay system 100. The delay system 100 is coupled to the data processing unit 510 and can continue supplying power for the data processing unit 510 when the external power supply unit 300 stops supplying power to the data processing unit 510. The protecting part 530 is coupled to the connecting unit 520 and the data processing unit 510.
The delay system 100 includes a delay controlling unit 110 and a discharging unit 120. The discharging unit 120 is coupled to the data processing unit 510 and the delay controlling unit 110 via a resistor R1 . In at least one embodiment, the discharging unit 120 is a rectifier.
The delay controlling unit 110 includes a transmission gate 111 and a divider resistance 113. The transmission gate 111 is coupled to the connecting unit 520, the resistor R1, and the data processing unit 510. The divider resistance 113 includes a second resistor R2 and a third resistor R3. A first end of the second resistor R2 is coupled to a first end of the third resistor R3 and the transmission gate 111, and a second end of the second resistor R2 is grounded. A second end of the third resistor R3 is connected to the connecting unit 520. The discharging unit 120 is connected to the connecting unit 520 via a protecting part 530.
When the external power supply unit 300 operates, the transmission gate 111 is switched on so that the power supply unit 300 supplies power to the data processing unit 510.
When the external power supply unit 300 stops supplying power to the server 500, the transmission gate 111 is switched off to disconnect the connecting unit 520 from the data processing unit 510. When the transmission gate 111 is switched off, the discharging unit 120 can discharge to supply power for the data processing unit 510 for a predetermined time period. Thus, the data processing unit 510 can store data in a buffering process.
Certain steps or methods described herein can be removed, others can be added, and the sequence of steps can be altered. The description and the claims drawn for or in relation to a method may give some indication in reference to certain steps. However, any indication given is only to be viewed for identification purposes, and is not necessarily a suggestion as to an order for the steps.
The embodiments described herein are illustrative, and should not be construed as limiting the following claims.
