Problems solved by technology

At the same time, in this solution, the CPU VPP signal is divided into multiple signals on the motherboard and connected to the backplane through cables, which cannot meet the topology requirements and the signal quality is poor.
If the problem of signal quality is solved by adding Switch chips according to the processing method of I2C signals, each CPU needs a Switch chip, which increases the cost
In addition, in this case, when the BMC accesses the hard disk, it needs to go through the secondary Switch chip, and the polling efficiency is low.

Abstract

The invention discloses a server supporting cascade connection of multiple backboards. The server comprises a mainboard, the mainboard is provided with a BMC, a mainboard low-speed connector, an Expander chip and a plurality of mainboard high-speed connectors, the BMC is connected to the mainboard low-speed connector through an I2C bus, and the BMC is connected to the Expander chip through the I2C bus; a plurality of backboards, each backboard is provided with an I2C repeater, a backboard low-speed connector and a backboard high-speed connector, the backboard low-speed connector and the backboard high-speed connector are connected with the I2C repeater, the multiple backboard low-speed connectors are sequentially connected in series and then connected with the mainboard low-speed connectors, and each backboard corresponds to one mainboard high-speed connector, each backboard high-speed connector is connected with the corresponding mainboard high-speed connector and then is connected to the Expander chip; the BMC is configured to detect the in-place backboards and enable the I2C repeater of any in-place backboard, and the backboards where the enabled I2C repeaters are located serve as gated backboards. The server provided by the invention solves the problem of duplicate I2C addresses of cascaded backboards, improves the polling efficiency of the BMC accessing the backboard equipment, and reduces the load of the I2C bus.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a server supporting multi-backboard cascading. Background technique [0002] With the rapid development of cloud computing applications, informatization and intelligence have gradually covered all fields of society. People communicate more and more through the network in their daily work and life, and the amount of network data is also growing explosively. As the core equipment for processing and storing data, the server has higher and higher requirements for performance and configuration. In order to meet the complex and diverse application scenarios of different users in various fields, the configuration of the server also needs to be more flexible and changeable. For example, when a server is used in the field of large-capacity storage, more PCIe resources need to be allocated to hard disks through the backplane, while when the server is used in the computing field, only a sm...
