Description
Technical field
The present invention relates to server admin plate field, specifically a kind of management of collectable multinode management information
Plate.
Background technique
As the requirement that user calculates density and storage density to server is higher and higher, a kind of novel high density service
Device-Rack Cabinet-type server is come into being.Cabinet-type server can at most place 3 server master boards in the space 1U.
In the cabinet of standard, a server master board more than 80 can be easily placed, the calculating density and storage of server greatly improved
Density.Situations such as unlike common PC, the reliability of server is extremely important, unexpected delay machine occurs, which often will cause, to be difficult to
The loss made up.
Therefore, server need O&M engineer grasp at the moment resource utilization of each node, power consumption, memory space,
Many management informations such as board health status, temperature, network rate, as far as possible by problem precognition before generation, utmostly
On avoid loss generation.O&M engineer is generally by mainboard BMC(baseboard management controller) on iic bus collect it is each
The management information of node, the management information of each node pass through iic bus to management board transmitting oneself state information, but due to
The address the IIC default of each node is identical, is easy to appear address conflict, and the management letter of each node is correctly collected to management board
Breath causes difficulty.
Summary of the invention
The present invention is directed to the demand and shortcoming of current technology development, provides a kind of collectable multinode management information
Management board.
A kind of management board of collectable multinode management information of the present invention solves the technology that above-mentioned technical problem uses
Scheme is as follows: a kind of management board of collectable multinode management information, is provided with a multistage IIC on the management board
Switch chip and management board (BMC) controller, the BMC controller and more IIC Switch chips are handed over
The iic bus of mutual communication, each node is connected on the management board by cable, and BMC controller is to IIC Switch
Chip sends information and controls its some downstream interface and upstream Interface connection, and management board is successively accessed just as IIC
The each node and collection management information of location.
Preferably, the multistage IIC Switch chip uses three-level IIC Switch chip, and the IIC
Switch chip is four tunnel downlinks uplink all the way.
Preferably, when the BMC controller accesses any node iic bus, the first order, second are successively gated
Grade, third level IIC Switch chip realize the connection of BMC controller and node I2C bus.
The beneficial effect that a kind of management board of collectable multinode management information of the present invention has compared with prior art
Fruit is: management board of the present invention, by using I2C switch chip, realizes the access of I2C bus address identical to multinode, energy
Enough collect the management information of multiple nodes；It is identical to receive the address each node IIC, compatibility is high, improves each node
The collection efficiency of management information；By management board firmware mapping management information and actual node, flexibility ratio is high；It solves more
The problem of collection management information, at low cost under the same case of the address node IIC, realizes easy, raising management board compatibility, contracting
The short R&D cycle reduces research and development cost, improves product quality, has very high practical value.
Detailed description of the invention
Attached drawing 1 is the schematic diagram of the management board of the collectable multinode management information；
Attached drawing 2 is the schematic diagram of the multistage IIC Switch chip.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this hair
A kind of bright management board further description of collectable multinode management information.
In view of the more difficult problem of collection management information under the same case of the address each node IIC, the present invention proposes that one kind can
The management board for collecting multinode management information is realized successively to each identical IIC by using multistage IIC Switch chip
The node visit of location, and its management information is collected, multiple node administration information can be easily collected, and not will cause different mainboards
Between IIC address conflict, working efficiency greatly improved.
Embodiment:
The management board that multinode management information is collected described in the present embodiment is arranged on the management board as shown in Fig. 1
There are a multistage IIC Switch chip and management board (BMC) controller, the BMC controller and more IIC
Switch chip interactively communicates, and the iic bus of each node is connected on the management board by cable, BMC controller
Information is sent to IIC Switch chip and controls its some downstream interface and upstream Interface connection, and management board is successively visited
Ask each node and collection management information just as the address IIC.
The signal of the multistage IIC Switch chip is as shown in Fig. 2, and IIC Switch chip is an IIC device,
There is the iic bus address of its own, management board (BMC) controller is different by being written to IIC switch chip address
Information, can choose downstream interface it is any all the way with upstream Interface connection；Multistage IIC can be realized in a comparable manner
The connection of Switch, and connection can be successively established step by step.
In the present embodiment, the multistage IIC Switch chip uses three-level IIC Switch chip, and the IIC
Switch chip is four tunnel downlinks uplink all the way, as described in Fig. 1, under shown topological structure, so that the management board is most
96 groups of iic bus inputs can be connected.
In this implementation, when the BMC controller accesses any node iic bus, the first order, the are successively gated
Second level, third level IIC Switch chip realize the connection of BMC controller and node I2C bus.In this way, realizing
BMC controller successively gates the iic bus of itself and each node, can collect the management of all nodes of whole cabinet
Information.
This collects the management board of multinode management information, and specific implementation process is as follows: 1, first by management board with it is each
The iic bus of node connects, and 2, the three-level IIC Switch chip is successively gated by BMC controller, collect one
The management information of node, 3, repetition step 2, collects the management information of all nodes.In this way, the management board can be used easily to receive
Collect more than 80 mainboard management informations, and not will cause the IIC address conflict between different mainboards.
Above-mentioned specific embodiment is only specific case of the invention, and scope of patent protection of the invention includes but is not limited to
Above-mentioned specific embodiment, any person of an ordinary skill in the technical field that meet claims of the present invention and any
The appropriate change or replacement done to it, all shall fall within the protection scope of the present invention.
