Control method, system and readable storage medium for N-level PCIE expansion box

Abstract

The invention discloses a control method, system and readable storage medium for an N-level PCIE expansion box. The method comprises: after receiving a power-on trigger signal, the BMC of the i-th PCIE expansion box detects whether there is an i+1th-level PCIE expansion box connected thereto; if not, a power-on operation is performed; if yes, a power-on trigger signal is sent to the i+1th-level PCIE expansion box, and the power-on flag bit of the i+1th PCIE expansion box is queried according to a preset rule, when the power-on flag bit of the i+1th-level PCIE expansion box is in a first state,and the power-on operation is performed; when the BMC of the CPU server queries that the power-on flag bits of all the PCIE expansion boxes are in the first state, the CPLD of the CPU server is controlled to start a second power-on sequence. The control method is easy to implement, and when controlling the CPU server combination connected with the N-level PCIE expansion box, it only needs to be controlled once, which saves a lot of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a control method, system and readable storage medium of an N-level PCIE expansion box. Background technique [0002] With the continuous development of cloud computing and big data, various fields have gradually transformed the traditional data computing model into cloud computing. With the increase of business volume, the amount of data storage and processing in the server system is also increasing. In order to save costs, the existing technology is generally to increase the storage space by connecting multiple PCIE expansion boxes in series or in parallel on the server. and the purpose of improving computing power. During on-site delivery and system upgrades, staff are required to manually control each PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) expansion box and CPU (Central Processing Unit, central processing unit) se...
