Hot plugging architecture and method for lowering switch power dissipation and storage server

Abstract

The invention discloses a hot plugging architecture and a method for lowering switch power dissipation and a storage server. The hot plugging architecture comprises a hot plugging controller, at least two control switches and a current detection resistor, the control switches are in parallel connection and are afterwards connected with the hot plugging controller, the hot plugging controller is further connected with the current detection resistor, and the output end of the current detection resistor is connected with the input ends of the control switches after the control switches are in parallel connection. According to the comparison of the hot plugging architecture and the method for lowering the switch power dissipation and the storage server and the prior art, through the parallel connection of the control switches, the loss of the control switches themselves is lowered, the loss of the storage server can be effectively lowered, on the basis that the storage server is used for the internet in a large scale, the energy can be well saved, the cost of electric charge of a client can be well reduced, the practicability is high, the application range is wide, and thus the hot plugging architecture is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a hot-swappable architecture for reducing switch power consumption, a storage server and a method. Background technique [0002] With the development and wide application of storage server technologies, people pay more and more attention to the power consumption of storage servers. The current general-purpose storage server generally adopts a hot-swappable design scheme, that is, a design scheme using an integrated chip control switch: a control switch is designed at the input end of the system to achieve the purpose of cutting off the system power when the system is abnormal. However, due to the equivalent impedance of the control switch itself and the large current of the storage server, the control switch itself will generate a lot of loss. [0003] Such as figure 1 In the hot-swap design scheme of the existing storage server shown, the hot-swap circuit structure is composed...

Problems solved by technology

[0004] Due to the large system current I, even if the equivalent impedance of the control switch has been reduced to the lowest in the industry, in this case the power loss of the switch is still relatively large. In the case of a large number of general-purpose storage servers, this loss has a great impact on power costs and There is a lot of pressure to save energy
