Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Currently, the different controllers in a clustered storage system typically communicate using the SCSI protocol. When the SCSI protocol sends data, many preparation links need to be performed, and in a data sending or receiving process, roles of a Target end and an Initiator end are fixed, so that an existing communication flow is cumbersome, and communication efficiency and communication convenience need to be improved. Therefore, the communication scheme is provided, and the communication efficiency among different controllers in the cluster storage system can be improved.
Referring to fig. 1, an embodiment of the present application discloses a communication method applied to a target controller, including:
and S101, if the target controller is started, establishing communication paths with other controllers respectively.
Wherein the target controller and the other controllers belong to the same cluster storage system. The other controllers are all controllers except the target controller in the cluster storage system.
In one embodiment, establishing communication paths with other controllers respectively includes: controlling local FC drives to be communicated with FC drives of other controllers respectively so as to establish a communication path; recording connection information of the communication path, the connection information including: controller identification information corresponding to the communication path.
For example: if the identification information of the target controller is a and the identification information of the target controller is B, the connection information includes: a and B. The connection information is stored in both the target controller and the object controller. One communication path corresponds to one connection information. There may be multiple FC cards on any one controller, and thus multiple communication paths between the two controllers may exist.
S102, selecting an object controller from other controllers, sending a negotiation request to the object controller through a communication path corresponding to the object controller, so that the object controller determines the maximum common channel number commonly supported by the object controller and the object controller according to the negotiation request, and returning the maximum common channel number to the object controller.
The object controller is any one of the other controllers.
In one embodiment, the determining, by the object controller, the maximum number of common channels supported by the object controller and the object controller in common according to the negotiation request includes: the object controller analyzes the negotiation request, obtains the maximum target channel number supported by the target controller, and compares the maximum target channel number with the maximum object channel number supported locally to determine the maximum common channel number. Wherein, the negotiation request includes: the maximum number of target channels supported by the target controller, therefore, the target controller compares the maximum number of target channels supported by the target controller with the maximum number of target channels supported by the target controller, and the maximum number of common channels supported by both the target controller and the target controller can be determined.
For example: the maximum number of target channels supported by the target controller is 3, and the maximum number of target channels supported by the target controller is 4, so that the maximum number of common channels supported by both the target controller and the target controller is the minimum number of 3 and 4, and therefore the maximum number of common channels is 3.
S103, sending a channel creating request to the object controller according to the maximum common channel number so that the object controller creates a channel pool according to the channel creating request and sends the channel creating request to the target controller.
In one embodiment, the pool of channels is created based on the SCSI protocol.
And S104, creating a channel pool according to the channel creation request so that the target controller and/or the object controller can communicate by using the channel pool.
In one embodiment, the object controller and/or the object controller communicates using a channel pool, comprising: and if the target controller and/or the object controller need to send data to the opposite side, the target controller and/or the object controller selects any channel from the channel pool to send the data to the opposite side.
It should be noted that the channel pool created by the target controller is the same as the channel pool created by the object controller, but the identification information recorded by the target controller and the identification information recorded by the target controller are different. For example: in the target controller, the sending end of the record is the target controller, and the receiving end is the target controller. In the object controller, the sending end of the record is the object controller, and the receiving end is the object controller.
In order to avoid that the channel always occupies the resource (i.e., channel resource) driven by the FC, if the target controller and/or the object controller do not need to send data to the other side within the preset time period, the target controller and/or the object controller simultaneously releases the channel resource corresponding to the target channel in the channel pool. Namely, some deletable target channels are selected from the channel pool and deleted to release their corresponding channel resources.
After releasing some channels, the available channels in the channel pool may not be enough, so that a new channel can be created in time, and therefore when the number of channels in the channel pool is less than the maximum number of common channels, a new channel is added in the channel pool, so that the number of channels in the channel pool is equal to the maximum number of common channels.
In a specific embodiment, after the target controller and/or the object controller simultaneously releases the channel resource corresponding to the target channel in the channel pool, the method further includes: and the target controller and/or the object controller judges whether the number of the channels in the channel pool is less than the maximum common channel number, if so, the channels are newly added in the channel pool so as to enable the number of the channels in the channel pool to be equal to the maximum common channel number.
Therefore, after the controller is started, the channel pool which can be communicated with other controllers is immediately established no matter whether data needs to be transmitted currently or not, and then the data can be directly transmitted when the data needs to be transmitted subsequently, so that the communication efficiency and the communication convenience can be improved. Therefore, each controller in the cluster storage system can be used as an Initiator end to initiate the creation of the channel pool, each controller can also be used as a Target end to passively create the channel pool, and subsequently, in the data interaction process, the role limitation of the Target end and the Initiator end does not exist, and the data interaction can be completed by directly using the channel pool, so that the communication convenience and flexibility are improved, the communication time delay can be reduced, and the communication quality is improved.
Referring to fig. 2, an embodiment of the present application discloses a communication scheme, where the scheme includes:
1. the controller finds:
when a certain controller in the cluster storage system is started, the FC drive of the certain controller interacts with the FC drives of other controllers, so that the communication condition of the certain controller and other controllers can be obtained, several available communication paths (paths) exist with any other controller, and the connection information of each communication path is recorded in each controller by using the structure of CO logic.
2. A channel pool creating process:
after the controller stores the connection information, the controller, as an Initiator end, actively initiates a negotiation request (SCSI format command) before channel establishment to other controllers to negotiate the maximum common channel number supported by both parties. In the negotiation request, the maximum number of channels supported by the Initiator end is included, so that the other controllers receiving the negotiation request can compare the maximum number of channels supported by themselves with the maximum number of channels supported by the Initiator end, thereby determining the maximum number of common channels. At this time, the other controllers receiving the negotiation request as the Target end return the maximum number of common channels to the Initiator end, and the Initiator end will send corresponding number of SCSI commands for establishing channels according to the maximum number of common channels, so that the Target end and the Initiator end can create a channel pool (channel pool) for both-side communication.
3. Dynamically adjusting the number of channels:
it should be noted that, if the cluster storage system includes N controllers, N-1 channel pools are stored in each controller, and each channel pool corresponds to another controller one to one. In addition, the number of channels included in each channel pool can be flexibly adjusted according to the actual communication situation, so that idle channels are prevented from always occupying FC-driven resources.
Specifically, for any two controllers, one of the controllers serves as a Target end to send response data to an Initiator end every 800ms, after the Initiator end receives the response data, the state is replied, and at this time, the Initiator end and the Target end simultaneously release channel resources corresponding to a specified number (which is a preset value and is smaller than the maximum common channel number) of channels. After the channel resource is released, because the maximum number of the common channels is not reached, some channels can be added to the channel pool, so that the number of the channels in the channel pool is equal to the maximum number of the common channels. It is envisioned that the number of channels in the channel pool between two controllers is always dynamically adjusted. Namely: each channel has a life cycle of the channel, so that the FC-driven resource is not occupied all the time, and the data transmission efficiency can be ensured.
4. And (3) data transmission process:
according to the above, any two controllers in the cluster storage system can establish a channel pool for two-way communication. If the controller has service data to send, selecting a channel in idle state from the channel pool corresponding to the receiver of the service data to send the service data directly. The relevant parameters and English abbreviations shown in FIG. 2 refer to the relevant explanations of the prior art, and the description of this embodiment is omitted.
Therefore, in the embodiment, any two controllers implement a dynamic channel pool in advance, so that a complex interaction flow is avoided, the time delay of communication between the controllers is reduced, and the communication quality is improved.

In one embodiment, the target controller and/or the object controller determines whether the number of channels in the channel pool is less than the maximum number of common channels, and if so, adds a new channel in the channel pool to make the number of channels in the channel pool equal to the maximum number of common channels.
