Control system, a switch and a method for controlling execution device

Abstract

The invention discloses a control system, a switch and a method for controlling an execution device. The control system comprises a processor, a control module and address resolution modules. The processor is connected with the control module through a peripheral component interconnection high-speed PCIe bus, the control module is connected with one or more address resolution modules through address buses, and each address resolution module is set to be connected with one execution device, wherein address information of a to-be-controlled port on each execution device is set on the processor in advance, and the address information is used for enabling the processor to address a corresponding address resolution module through the control module. According to the control system, the number of occupied pins of the control module can be reduced, a specially developed driving program is not needed, the control logic is simple, and the operation is stable.

Description

technical field [0001] The invention relates to control technology, in particular to a control system, a switch and a method for controlling an execution device. Background technique [0002] In the past ten years, cloud data centers have achieved rapid development. From governments to enterprises, a consensus has been reached on cloud-based services. In this context, cloud data centers have higher and higher requirements for network quality. These requirements are mainly reflected in network bandwidth, network delay and storage capacity. For data center operators, the main means to obtain greater network bandwidth is to increase the number of ports and bandwidth density on the switch, that is, to control more optical modules in the switch; the way to increase storage capacity is to increase storage servers The number of hard disks in the . As the number of optical modules or hard disks increases, the difficulty in designing the backplane of the facility including these o...

Problems solved by technology

Another way to control the operation of the switch is that the processor will send instructions to the control module through the PCIe bus. The control module is connected to multiple IO expansion modules through the I2C bus. Each IO expansion module controls an optical module. This method has complex control logic. It needs to be integrated as a driver specially developed for the hardware architecture of the IO expansion module, which is difficult to develop and inefficient, and prone to exceptions
