Rack server data management system and method

The invention relates to a data management system and method, in particular to a rack server data management system and method.

Some of the rack servers developed at present integrate the advantages of intensive computing and centralized management of the conventional blade server, and integrate the features of flexible server configuration. Due to the large number of management boards, the management board of the well-known management board uses the management method of the chip and the motherboard Pin-to-Pin. The shortage of IO resources obviously increases the cost significantly.

In addition, when the BMC (Baseboard Management Controller) of the system board requests the system to manage the data of the chip, it is always known that the motherboard does not respond. For example, a motherboard with a high request frequency will appear. Multiple responses, and the board with low request frequency has not responded.

In view of the above, it is necessary to provide a rack server data management system and method capable of effectively preventing a host board requesting data from generating an unresponsive condition.

And the control module, the system management chip includes a management module and a data processing module, wherein the detection module is configured to detect whether the motherboard sends a data request, and the determining module is used for After detecting the data request, the detecting module determines whether the data request is sent by at least two motherboards. The management module is provided with an arbitration module, and the arbitration module is sent by at least two motherboards. When the data request is started, and the data request is prioritized, the management module is configured to sequentially send the data request to the control module in the order of the priority order, and the control module is configured to receive each After the data request, an interrupt request is sent to the data processing module, so that the data processing module starts data transmission to the corresponding motherboard.

A rack server data management method for processing data requests of a plurality of motherboards includes the following steps:

A detection module of the CPLD detects whether a motherboard sends a data request;

The determining module of the CPLD determines whether the data request is sent by at least two motherboards after the detecting module detects the data request;

One of the CPLD arbitration modules is started when at least two motherboards issue a data request, and the data requests are prioritized;

a management module of the system management chip sequentially sends a data request to one of the CPLD control modules in the order of the priority order;

The control module sends an interrupt request to a data processing module of the system management chip; and

The data processing module starts data transmission to the corresponding motherboard.

Compared with the prior art, in the above rack server data management system and method, the arbitration module in the management module of the system management chip is started when at least two motherboards issue a data request, and the data request is made. Performing priority ordering; the management module sequentially sends a data request to the control module of the CPLD in the order of the priority order, thereby starting data transmission. The data request sent by each motherboard will be processed, and there will be no unsuccessful response from the motherboard requesting the data.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram showing the connection of a preferred embodiment of the rack server data management system of the present invention.

2 is a flow chart of a preferred embodiment of a rack server data management method of the present invention.

Referring to FIG. 1, in a preferred embodiment of the present invention, a rack server data management system is used to process data requests of a plurality of motherboards 100. Each motherboard includes a BMC 101. The rack server data management system includes a CPLD (Complex Programmable Logic Device) 10 and a system management chip 20. Each BMC 101 connects the CPLD 10 by a communication bus.

The CPLD 10 includes a detection module 11 , a determination module 13 and a control module 15 .

The system management chip 20 includes a management module 21 and a data processing module 23.

The detecting module 11 is configured to detect whether the BMC 101 sends a data request. Each data request has a request frequency.

The determining module 13 is configured to determine whether the data request is sent by multiple BMCs 101. If so, the arbitration module in the management module 21 is activated. If not, it means that only one BMC 101 issues a data request, and the data request is directly sent to the control module 15.

The arbitration module in the management module 21 is started when the plurality of BMCs 101 issue a data request. The arbitration module prioritizes the data requests sent by the plurality of BMCs 101. The BMC 101 with a high request frequency has a lower priority than the BMC 101 with a low request frequency. The management module 21 sequentially sends the data request to the CPLD 10 in order of priority from the highest priority after the priority ordering is completed.

The control module 15 is configured to encode the motherboard information corresponding to the BMC 101 that sends the data request after receiving the data request, and simultaneously send an interrupt request to the data processing module 23 of the system management chip 20.

The data processing module 23 responds to the interrupt request, and decodes the information of the motherboard, and then selects a corresponding communication bus according to the decoded information of the motherboard to start data transmission.

The BMC 101 is configured to send an end signal to the CPLD 10 after receiving the data.

The determining module 13 is further configured to determine whether the end signal of all the BMCs 101 that have sent the data request is received. If so, the data transfer ends; if not, the data processing module 23 continues the data transfer until the CPLD receives the end signal of all BMCs 101 that issued the data request.

Referring to FIG. 2, a rack server data management method is provided for responding to data requests of a plurality of motherboards 100. The rack server data management method includes the following steps:

S10: The detecting module 11 detects whether the BMC 101 sends a data request.

S20: The determining module 13 determines whether the data request is sent by multiple BMCs 101. If so, step S30 is initiated; if not, step S50 is initiated.

S30: The arbitration module in the management module 21 is started, and the arbitration module prioritizes the data requests sent by the multiple BMCs 101. The arbitration module performs priority ordering according to the frequency of the request.

S40: The management module 21 sequentially sends data requests to the control module 15 in the order of priority. The management module 21 sequentially sends data requests to the control module 15 in descending order of priority. The BMC 101, which has a high number of responses, has a higher priority than the BMC 101 with a low request frequency.

S50: The control module 15 encodes the motherboard information corresponding to the BMC 101 that sends the data request, and simultaneously sends an interrupt request to the data processing module 23 of the system management chip 20.

S60: The data processing module 23 responds to the interrupt request, and decodes the information of the motherboard, and then selects a corresponding communication bus according to the decoded information of the motherboard, and starts data transmission.

S70: The BMC 101 sends an end signal to the CPLD 10 after receiving the data.

S80: The determining module 13 determines whether the end signal of all the BMCs 101 that have sent the data request is received. If so, the data transfer ends; if not, the process returns to step S40.

S90: End.
