Blade server control method and console

Abstract

The invention discloses a blade server control method and a console. The control method comprises the following steps: after a remote terminal establishes connection with a management blade, the management blade sends a master control data packet formed by a console command which is sent to the blades and is sent by the remote terminal to the corresponding blades through a console bus; the management blade sends console data emitted by the blades to the remote terminal according to a specified timeslot sequence through the console bus. The console comprises a master control unit arranged in the management blade and is characterized in that: the master control unit is communicated with an interface controller on a blade mainboard through the console bus. The console bus comprises a master control data line, a blade data line and a clock signal line. By using the method and the console of the invention, real-time data transmission without data loss of single-master equipment and multiple slave equipment from the management blade to the blades and multiple master equipment and single slave equipment from the blades to the management blade can be supported.

Description

technical field [0001] The invention relates to the field of blade server systems, in particular to a blade server control method and a console. Background technique [0002] Blade servers have become the mainstream of high-performance computing clusters. In the global TOP500 and domestic TOP100 supercomputer systems, many new cluster systems have adopted the blade architecture. Since each blade motherboard is an independent server unit, each blade needs to be designed with an independent peripheral interface so that the system administrator can individually operate and control the blade. Today's large-scale high-performance computing cluster systems basically use the Linux operating system, which makes the console function of the blade motherboard one of the must-have functions in the design of the blade server system. [0003] In the prior art, the realization of the console function of the blade mainly has the following several measures: the one is to design an independe...

Problems solved by technology

[0004] However, among the above various schemes, the first scheme is inconvenient to operate. In fact, due to the increasing scale of the high-performance cluster system, local operation control has become unrealistic; the second scheme requires additional network hub equipment and A large number of cable connections increase the complexity of the system and reduce the reliability of the system; the third solution uses the standard management bus to realize the transmission of console data, but the standard management bus is suitable for single-master and multi-slave structures. The blade server console data transmission has the following characteristics: the data transmission from the management blade to the blade is a single-master device with multiple slave devices, and the data transmission from the blade to the management blade is a multi-master device with a single-slave device

For the multi-master and single-slave form of data transmission from multiple server blades to a single management blade, the existing bus cannot realize real-time data transmission, and at the same time, data loss will occur when multiple blades output a large amount of data
