Problems solved by technology

[0003] However, the power supply on the blade server often needs to design its power wattage according to the number of blade units. The reason is that the electronic device will require a large starting current at the moment of startup, and the actual working current after startup However, it is not high. Usually the starting current will be several times the actual working current. This problem is the problem of surge current (Surge Current). Therefore, when the blade server is turned on, because the blade units adopt a simultaneous start mechanism, its The resulting starting current is very large. If the power wattage of the power supply cannot match or the protection circuit trips, it will cause the server to fail to start. Therefore, it is often necessary to design a power supply with high power wattage to match the startup. The required current, but this will relatively increase the cost of manufacturing. Under the trend of the current meager profit era, methods that can reduce manufacturing costs have become one of the important research directions for designers and manufacturers.

Embodiment Construction

[0012] Please refer to figure 1 , is a system block diagram of the present invention, including a blade unit 100, a blade unit 110, and a blade unit 120, which are jointly installed on the backplane 200 to form a loop with each other, wherein the blade unit 100, the blade unit 110, and the blade unit 120 are respectively It has a start module 10, a start module 20, a start module 30, a detection module 1, a detection module 2 and a detection module 3. These start modules are used to generate a start signal and receive a start number, which can be generated and received through a general input The (General Purpose Input; GPI) pin receives the start signal, and the general purpose output (General Purpose Output; GPO) pin outputs the start signal, wherein the start signal can be a high-level signal or a low-level signal, and the detection module is used to Detect whether the general-purpose input and output pins of the startup module receive or generate the startup signal normall...

Abstract

A method for starting up blade unit of blade server cyclically includes utilizing circuit set in blade unit to switch on power supply of blade unit cyclically for avoiding surge current of existing server when it is started up instantly, enabling to design power supplier of server to be on specification with small power for decreasing production cost.

Description

【Technical field】 [0001] The present invention relates to a circuit and its method related to sequential start-up, in particular to a circuit and its method for sequential start-up of blade units of a blade server. 【Background technique】 [0002] A blade server is a kind of processor, memory, hard disk, etc. integrated into a single motherboard to form a motherboard with server system functions, and each motherboard is collectively referred to as a blade unit, and these blade units are collectively Installed on a backplane (Back plane), and share a chassis (Chassis), power supply, keyboard, mouse, monitor and other resources, and in one chassis, more than 20 servers with blade units can be placed at the same time , because of its small size, space saving, easy management, low total cost of ownership, etc., the blade server is gradually favored by the business community, and some designs are more tolerant of hot swapping, which is used when the blade unit is found to be fault...
