Abstract

The invention provides a method for implementing a redundant management module in a compact peripheral component interconnect (CPCI) blade server. A complex programmable logic device (CPLD) is arranged on a backboard to control and switch red, green and blue (RGB), universal serial bus (USB) and inter-integrated circuit (I2C) signals; and the control principle is that: if a main management module is connected and normally works, the main management module is used for management in spite of the connection of a slave management module; if the main management module fails in the working process, the slave management module can take over the work; and after a new management module is connected to the position of the main management module, if the new management module works normally, the new management module can take over the work again. Compared with the prior art, the method for implementing the redundant management module in the CPCI blade server has the advantages that: the whole process is simple and convenient, and the whole reliability and redundancy are high, so the method has high popularization and use value.

Description

The implementation method of Redundancy Management System in the CPCI blade server

Technical field

The present invention relates to KVM administration module redundancy field in the blade server, specifically the implementation method of Redundancy Management System in the CPCI blade server.

Background technology

Blade server is the low-cost server platform of a kind of HAHD, is to be that special applications industry and high density computer environment design specially, and wherein each piece " blade " in fact is exactly a block system motherboard, is similar to one by one independently server.The favor that blade server is high-effect with it, manageability is subjected to the consumer day by day, the blade server of CPCI interface is because its harsh applied environment, make it higher requirement arranged on to high reliability and redundancy on basis of original blade server, and the administration module that wherein is used for KVM OVER IP and system monitoring just become just important further for the requirement of reliability and redundancy.

Summary of the invention

Technical assignment of the present invention is in the deficiencies in the prior art, and the implementation method of Redundancy Management System in a kind of CPCI blade server is provided.

Technical scheme of the present invention realizes in the following manner, the implementation method of Redundancy Management System in this CPCI blade server, the concrete steps of this implementation method are: step 1, administration module and server unit are connected on the server backboard by the CPCI interface, and this administration module comprises the main management module and from administration module; Step 2 is installed on described server backboard a complex programmable logic device (CPLD) is set, and this CPLD is responsible for controlling RGB, USB, the I2C signal with switching management module, server unit; Step 3, realize Redundancy Management by administration module: in the main management module with when administration module inserts simultaneously, the work of main management module, do not work from administration module, if the main management module breaks down in the course of the work, after CPLD detects, replace the main management module from administration module and carry out work, be replaced by administration module working properly until the main management module.

Usb signal after described administration module transmission network signal, the switching and rgb signal are to the CPLD. of backboard

Described network signal is applied to KVM OVER IP.

Described usb signal and rgb signal are applied to local display and USB device.

The beneficial effect that the present invention is compared with prior art produced is:

The implementation method of Redundancy Management System is placed control and the switching that piece of CPLD is finished RGB, USB and I2C signal in the CPCI blade server of the present invention on backboard, cooperate the Redundancy Management that realizes blade server simultaneously by the main management module with from administration module, good reliability has good value for applications.

Description of drawings

Accompanying drawing 1 is the multiple-unit blade server structural representation of Redundancy Management System of the present invention.

Accompanying drawing 2 is the inner block diagrams that connect of backboard of the present invention.

Accompanying drawing 3 is workflow diagrams of Redundancy Management of the present invention.

Embodiment

Below in conjunction with accompanying drawing the implementation method of Redundancy Management System in the CPCI blade server provided by the present invention is done following detailed description the in detail.

As accompanying drawing 1, shown in Figure 2, the implementation method of Redundancy Management System in this CPCI blade server, the concrete steps of this implementation method are:

Step 1 is connected administration module and server unit on the server backboard by the CPCI interface, and this administration module comprises the main management module and from administration module;

Step 2, on described server backboard, install a complex programmable logic device (CPLD) is set, this CPLD is responsible for control and switching management module, the RGB of server unit, USB, the I2C signal, main management module and transmit by signal CMM1_CON and CMM2_CON from communicating by letter between administration module and the backboard CPLD, after the main management module powers on and works, CPLD by CMM1_CON notice backboard, after powering on and work from administration module, by the CPLD of CMM2_CON notice backboard, CPLD next can by these two groups of signal periods with the main management module, from administration module communication;

Step 3, as shown in Figure 3, realize Redundancy Management by administration module: when CMM1 and CMM2 insert simultaneously, CMM1 will work, CMM2 does not work, if CMM1 breaks down in the course of the work, CPLD is after detecting, and CMM2 will take over the work of CMM1, if after this user replaces the CMM1 of fault with the normal administration module of work, it is the main management module that the new administration module that inserts will become CMM1, takes over the work of CMM2, and CMM2 no longer works.

Described network signal is applied to KVM OVER IP.

Described usb signal and rgb signal are applied to local display and USB device, and this USB device comprises keyboard, mouse etc.

The implementation method of Redundancy Management System is by placing control and the switching that piece of CPLD is finished RGB, USB and I2C signal in the CPCI blade server of the present invention on backboard.The principle of control is that then main management module is in charge of if the main management module inserts and be working properly, and no matter whether insert from administration module.If the main management module breaks down, will take over work from administration module, after inserting new administration module in the position of main management module in the process of work, if it is working properly, then can take over work again, whole reliability and redundancy are good, thereby have good value for applications.
