Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
The embodiment of the present application discloses a kind of backboard configuration information access method of binode storage system, is applied to main section
Point, it is shown in Figure 1, this method comprises:
Step S11: when the host node itself needs to carry out data access to backboard configuration information database, then the is triggered
One access request, and corresponding access operation is carried out to the backboard configuration information database by first access request,
To obtain corresponding first access result；
Step S12: when needing to carry out data access to the backboard configuration information database from node, then obtain it is described from
The second access request that node is sent, and according to second access request, phase is executed to the backboard configuration information database
The access operation answered obtains corresponding second access as a result, being then back to the second access result described from node.
That is, from node being realized by host node between backboard configuration information database in the embodiment of the present application
What receiving was asked, that is, the access request that cannot be directly initiated from node using itself come to backboard configuration information database into
Row access, but need that access request is first transmitted to host node, then by host node according to the above-mentioned access request received
It accesses to backboard configuration information database, is finally again fed back to corresponding access result from node by host node.
Therefore in the embodiment of the present application, host node and the access request respectively initiated from node are passed via host node
Backboard configuration information database is reached, consequently facilitating the visit by host node come all nodes of control to backboard configuration information database
It asks, for example, receiving described the sended over from node just when host node is while initiating first access request
Two access requests, then host node at this time can be using two kinds of processing modes: one is by the way of " putting self before others ", namely first holding
Row access operation corresponding with first access request, then execute access operation corresponding with second access request；Separately
