Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The embodiment of the invention discloses the Mode Data means of communication of LUN a kind of, shown in Figure 1, this method includes：
Step S11：Receive the target Mode Data for the target LUN that target host node is sent.
Specifically, in cluster storage system, there are multiple LUN to form LUN collection, each LUN corresponds to corresponding node
(Node), LUN, which is concentrated, includes multiple LUN subsets, and each LUN subsets are corresponding with a Node subsets, each saved in Node subsets
Each LUN in its corresponding LUN subsets of point is connected, but the host node only in Node subsets could send LUN's
Mode Data, therefore, when any of LUN subsets LUN Mode Data change, by host node corresponding with LUN
Send Mode Data.
It is understood that target LUN target Mode Data, change for target LUN initial Mode Data
Mode Data afterwards, i.e. when target LUN some running status changes, target host node is just by target LUN target
Mode Data are sent to cluster state machine.
Wherein, record has some states and pattern of LUN operations etc. to be used for showing the current operations of LUN in Mode Data
Some information of state.
Step S12：Local target LUN history Mode Data are updated using target Mode Data and are preserved.
Step S13：Target Mode Data are sent into all nodes, so that each node updates target Mode
Data。
Specifically, after cluster state machine (Cluster) preserves target Mode Data, target Mode Data are sent to institute
Have in node, including target host node and host node in each Node subsets and from node, so that each node utilizes cluster
The target Mode Data for the target LUN that state machine is sent, update the target Mode Data for the target LUN that each node preserves.
It can be seen that cluster state machine receives the target Mode for the target LUN that target host node is sent in the embodiment of the present invention
Data, and target Mode Data are sent into all nodes, so that each node updates target LUN target Mode
Data, no longer by mutually forwarding target LUN target Mode Data between each node, but unification connects to cluster state machine
Receive the Mode Data of the LUN after the change that each host node is sent and send the Mode Data of the LUN after change to each section
Point, so that each node updates LUN Mode Data, reduce data access between each node, reduce synchronous LUN's
To the influence of I O access performance during Mode Data, the efficiency of cluster is improved, and reduces the influence to other I O process.
In actual applications, Node subsets exist with the formation of IO groups, therefore, the mesh that above-mentioned reception target host node is sent
LUN target Mode Data process is marked, can be specially the target Mode for receiving the target LUN that target IO groups are sent
Data, wherein, IO groups include target host node and corresponding with target host node from node, specifically, target host node will
Target LUN target Mode Data are sent to IO groups, and IO groups manage management of the structure realization to oneself state, IO by Group
The target LUN received target Mode Data are sent to cluster state machine by group again, and mesh is received so as to complete cluster state machine
Mark LUN target Mode Data process；Meanwhile target Mode Data are sent to IO groups, IO groups and connect by cluster state machine
After receiving target Mode Data, each node for target Mode Data being sent in IO groups, so that each node updates target
LUN target Mode Data.
It is understood that the target Mode for the target LUN that cluster state machine can be sent with real-time reception target host node
Whether Data, host node real-time judge LUN Mode Data change, the cluster state machine if LUN Mode Data change
The target Mode Data for the target LUN that real-time reception target host node is sent in real time.
Accordingly, it is shown in Figure 2 the embodiment of the invention also discloses the Mode Data communication systems of LUN a kind of, should
System includes：
Receiving module 11, the target Mode Data of the target LUN for receiving the transmission of target host node；
Update module 12, for updating local target LUN history Mode Data using target Mode Data and preserving；
Sending module 13, for target Mode Data to be sent into all nodes, so that each node updates target
Mode Data。
It can be seen that cluster state machine receives the target Mode for the target LUN that target host node is sent in the embodiment of the present invention
Data, and target ModeData is sent into all nodes, so that each node updates target LUN target Mode Data,
No longer by mutually forwarding target LUN target Mode Data between each node, but unification is each to the reception of cluster state machine
Host node send change after LUN Mode Data and send change after LUN Mode Data to each node so that
Each node updates LUN Mode Data, reduce data access between each node, reduce synchronous LUN Mode Data
When influence to I O access performance, improve the efficiency of cluster, and reduce the influence to other I O process.
In the embodiment of the present invention, above-mentioned receiving module 11, the Mode Data sent specifically for receiving target IO groups, its
In, IO groups include target host node and corresponding with target host node from node.
Above-mentioned module receives 11, can include real-time reception unit；Wherein
Real-time reception unit, the target Mode Data sent for real-time reception target host node.
It should be noted that LUN can utilize disk state data acquisition system management Mode Data, IO groups to use
Group management structure management LUN Mode Data renewal.
Finally, it is to be noted that, herein, such as first and second or the like relational terms be used merely to by
One entity or operation make a distinction with another entity or operation, and not necessarily require or imply these entities or operation
Between any this actual relation or order be present.Moreover, term " comprising ", "comprising" or its any other variant meaning
Covering including for nonexcludability, so that process, method, article or equipment including a series of elements not only include that
A little key elements, but also the other element including being not expressly set out, or also include for this process, method, article or
The intrinsic key element of equipment.In the absence of more restrictions, the key element limited by sentence "including a ...", is not arranged
Except other identical element in the process including the key element, method, article or equipment being also present.
A kind of LUN provided by the present invention the Mode Data means of communication and system are described in detail above, this
Apply specific case in text to be set forth the principle and embodiment of the present invention, the explanation of above example is only intended to
Help to understand method and its core concept of the invention；Meanwhile for those of ordinary skill in the art, the think of according to the present invention
