In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Referring to figure 2., Fig. 2 is the structural schematic diagram of the first Redundancy Management system provided in an embodiment of the present invention.
The Redundancy Management system is applied to storage server, comprising:
It is connect respectively with the first storage chip, the first PCH and the first Device, for supporting the first network of network communication
Switch chip 11；
The first BMC 12 being connect with first network switch chip 11；
It connect, is used for the second storage chip, the 2nd PCH, the 2nd Device and first network switch chip 11 respectively
Support the second network switch chip 21 of network communication；
The 2nd BMC 22 being connect respectively with the second network switch chip 21；
Wherein, the first BMC 12 and the 2nd BMC 22 is used to the network switch chip connected previously according to itself
Network connectivity requirements are its configuring network interface；The network switch chip connected in normal work to itself is external to be set
It is standby to be managed, and by management information through Network Synchronization to another BMC, in order to be taken over when itself failure by another BMC
The management work of equipment.
Specifically, the Redundancy Management system of the application includes first network switch chip 11 (switch: interchanger),
Two network switch chips 21, the first BMC 12 and the 2nd BMC 22, its working principle is that:
First BMC 12 passes through first network switch chip 11 and the first storage chip, the first PCH and the first Device
Connection, to realize that the first BMC 12 is interacted using network and the first storage chip, the first PCH and the first Device, thus
It is managed.It should be noted that the network interface of first network switch chip 11 is matched under heterogeneous networks application scenarios
Set usually it is different, need (i.e. external needed for first network switch chip 11 to set according to current network connectivity requirements
It is standby) depending on.In order to make first network switch chip 11 be suitable for current network application scene, the application is by the first BMC 12
Network interface configuration is carried out to first network switch chip 11 in advance, specifically according to current network connectivity requirements to first
Network switch chip 11 carries out initial configuration, makes it for the corresponding configuration heterogeneous networks interface of different external connection equipment, thus
Make the first BMC 12 that can successfully pass first network switch chip 11 to interact with remaining external equipment.
Similarly, the 2nd BMC 22 passes through the second network switch chip 21 and the second storage chip, the 2nd PCH and second
Device connection, to realize that the 2nd BMC 22 is handed over using network and the second storage chip, the 2nd PCH and the 2nd Device
Mutually, to be managed to it.Correspondingly, the application carries out net to the second network switch chip 21 in advance by the 2nd BMC 22
The configuration of network interface specifically carries out initial configuration to the second network switch chip 21 according to current network connectivity requirements,
Make it for the corresponding configuration heterogeneous networks interface of different external connection equipment, to make the 2nd BMC 22 that can successfully pass the second network
Switch chip 21 is interacted with remaining external equipment.
As it can be seen that when the first BMC 12 and the 2nd BMC 22 is worked normally, each BMC networks that itself is connected
The external equipment of switch chip is managed.
Based on this, if the first BMC 12 breaks down, will lead to the equipment that is managed originally by the first BMC 12 can not be after
It is continuous to be managed.Since the 2nd BMC 22 under normal condition can pass through the second network switch chip 21, first network
Switch chip 11 is interacted with script by the equipment that the first BMC 12 is managed, so the application is managing the feelings for itself corresponding to equipment
Under condition, can also the first BMC 12 of adapter tube management work, until the first BMC 12 is replaced or repaired to normal condition.It needs
It is bright, in order to make the work of successful the first BMC 12 of adapter tube of the 2nd BMC 22, the first BMC 12 is needed in normal work will
2nd BMC 22 is synchronized to the management information of equipment, in order to which the 2nd BMC 22 is in the first 12 failure of BMC, is based on first
The management information of BMC 12 continues to manage the equipment managed by the first BMC 12 originally (when the 2nd BMC 22 breaks down similarly,
Details are not described herein by the application).
Further, it is to be appreciated that the first BMC 12 and the 2nd BMC 22 are divided into main BMC and standby BMC, the two needs
According to active and standby strategy is preset, (such as when Redundancy Management system integrally works normally, the first BMC 12 is used as main BMC, the 2nd BMC 22
As standby BMC；When the first BMC 12 breaks down, the 2nd BMC 22 is used as main BMC, the first BMC 12 to be replaced or repair
Standby BMC is used as after to normal condition；When the 2nd BMC 22 breaks down, the first BMC 12 is re-used as main BMC, and second
BMC 22 be replaced or repair to normal condition after as standby BMC) clear itself active and standby identity, accordingly execute respective task.
The present invention provides a kind of Redundancy Management systems, are applied to storage server.The Redundancy Management system of the application is adopted
It is realized and is communicated with network communication mode, the communication speed of network communication mode is very fast, so that system is smaller by disturbance probability,
High stability；Moreover, can respectively be set using network connection for its management by another BMC when one of BMC breaks down
It is standby, thus make originally the storage system that is managed by failure BMC can continue to use, thus improve storage server stability and
Reliability.
