Description

Technical Field

[0001] This application relates to the field of computer technologies, and particularly to a method and device for implementing an in-band management middleware for docking multiple storages. Background Art

[0002] Currently, in a cloud computing scenario, an OpenStack (an open-source cloud computing management platform project) cloud platform will integrate storage resources and connect a storage system to the cloud platform for management. For the consideration of data security, some users need to deploy the OpenStack cloud platform on the external network and deploy the storage system on the internal network when deploying the environment, making it impossible for the OpenStack cloud platform to directly communicate with the storage through the TCP / IP network. The in-band management technology came into being. It enables the OpenStack cloud platform to send SCSI (Small Computer System Interface) commands to the storage device through the Cinder driver (a bridge for the OpenStack cloud platform to dock with the storage device) when there is no TCP / IP network, so as to realize the management of storage resources.

[0003] In order to make the in-band communication function more general, the in-band communication function in the cinder driver is extracted and encapsulated into a middleware, called the in-band management middleware. The in-band management middleware provides two main functions: providing Rest (Representational State Transfer) for upper-layer applications, converting Rest requests into storage CLI (Command Line Interface) management commands, encapsulating the CLI management commands in SCSI commands, and sending the management commands to the storage for execution in an in-band manner.

[0004] However, in the current technology, the in-band management middleware is deployed alone on a server. The in-band management middleware provides a set of Rest interfaces for the cinder driver to call. The in-band management middleware cannot identify the correspondence between the FC channel and the storage cluster, and one in-band management middleware can only dock with one set of storage clusters at the same time. This limits the usage scenarios of users, and they can only dock with one set of storage clusters. If there are several sets of storage clusters in a data center at the same time, they cannot be docked through one in-band management middleware, which brings inconvenience to users. Summary of the Invention

[0039] The following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] The embodiments of the present application provide a method for implementing an in-band management middleware for docking multiple storages, Figure 1This is a flowchart of a method for implementing an in-band management middleware for docking multiple storages provided by an embodiment of the present application. The in-band management middleware has the following advantages: First, universality: It provides a unified Rest interface externally. In theory, the upper-layer application can be any application. Not only can it be used by the OpenStack cloud platform in the future, but other virtualization platforms can also use it, such as VMWare. Second, decoupling: It separates the in-band management function from the function of the Cinder driver. This makes the maintenance of the Cinder driver and the maintenance of the in-band management function not affect each other. Third, convenient deployment: After making the in-band management into a middleware, the in-band management module can be deployed on any server, rather than being deployed along with the Cinder driver. However, in the current technology, the in-band management middleware is deployed separately on a server. The in-band management middleware provides a set of Rest interfaces externally for the Cinder driver to call. The in-band management host converts the Rest request into a storage CLI management command, encapsulates the CLI management command into a SCSI instruction, and sends it to the storage cluster through the FC channel. There may be multiple links between the storage cluster and the in-band management host, and each link is an FC channel. The in-band management host will select one FC channel from them to send the SCSI instruction when sending the SCSI instruction. In the current technology implementation, the in-band management middleware cannot identify the corresponding relationship between the FC channel and the storage cluster, so that an in-band management middleware can only dock one set of storage clusters at the same time. This limits the usage scenarios of users because in a data center, there are often several sets of storage clusters at the same time. The method for implementing an in-band management middleware for docking multiple storages provided by an embodiment of the present application can solve the above problems, realize the grouping of in-band channels and the selection of in-band channels. Thus, the in-band management middleware can dock multiple sets of storage clusters.

[0041] As Figure 1 shown, the method may include the following steps:

[0042] Step 101: Receive a management instruction, where the management instruction contains the target storage cluster information corresponding to the execution of the management instruction.

[0043] Specifically, the management instruction is sent by the upper-layer application. The in-band management middleware is used to provide a Rest interface for the upper-layer application, convert the Rest request into a storage CLI management command, encapsulate the CLI management command in a SCSI instruction, and send the management command to the storage for execution in an in-band manner. The in-band management middleware provides a unified Rest interface externally. In theory, the upper-layer application can be any application. Not only the OpenStack cloud platform can use it in the future, but other virtualization platforms can also use it, such as VMWare. The in-band management middleware receives the management instruction sent by the upper-layer application, such as a Rest request. The management instruction contains the target storage cluster information corresponding to the execution of the management instruction, such as clusterID. For example, a parameter clusterID is added to the Rest interface. This parameter is used to indicate which storage execution the upper-layer application hopes to send the management execution to. This parameter is a required item. If the upper-layer application does not pass this parameter when calling the Rest interface, the Rest request call fails.

[0044] Step 102: Parse the management instruction and obtain the identifier of the target storage cluster based on the target storage cluster information.

[0045] Specifically, after the in-band management middleware receives the management instruction sent by the upper-layer application, it parses the management instruction to obtain the target storage cluster information corresponding to the execution of the management instruction, and obtains the identifier of the target storage cluster, that is, the cluster ID, based on this target storage cluster information. For example, after the in-band management middleware receives a Rest request, it parses the clusterID parameter in the header to obtain the ID of the cluster, such as WWID.

[0046] Step 103: Obtain the target FC channel corresponding to the identifier of the target storage cluster, where the target FC channel is used to transmit instructions to the target storage cluster.

[0047] Specifically, based on the identifier of the target storage cluster, such as the cluster ID, obtain the target FC channel corresponding to the identifier of the target storage cluster. Among them, the FC channel (Fibre Channel, a mesh channel technology) is used to increase the transmission bandwidth of the hard disk protocol, focusing on the fast, efficient, and reliable transmission of data. The FC channel and the storage cluster correspond one-to-one through the identifier of the target storage cluster. The target FC channel is used to transmit instructions to the target storage cluster.

[0048] Step 104: Send the management instruction to the target storage cluster based on the target FC channel.

[0049] Specifically, the in-band management middleware sends the management instruction to the target storage cluster corresponding to the target FC channel based on the target FC channel. For example, it sends a SCSI instruction.

[0050] It can be seen that in the embodiment of the present application, by receiving a management instruction containing target storage cluster information, obtaining the identifier of the target storage cluster, identifying the corresponding target FC channel based on the identifier of the target storage cluster, and finally, based on the target FC channel, sending the management instruction to the corresponding target storage cluster. It is possible to identify and manage the FC channel. Based on the corresponding relationship between the storage cluster and the FC channel, after receiving the management instruction, the storage cluster to which the management instruction needs to be sent can be identified, and the FC channel corresponding to the storage cluster can be found according to the corresponding relationship. Furthermore, it is realized that an in-band management middleware can be docked with multiple sets of storage clusters.

[0051] In an embodiment of the present application, in step 104, sending the management instruction to the target storage cluster based on the target FC channel includes: step 1041: generating a SCSI instruction based on the identifier of the target storage cluster and the management instruction; step 1042: sending the SCSI instruction to the target storage cluster through the target FC channel.

[0052] Specifically, the in-band management middleware is used to provide a Rest interface for the upper-layer application, convert the Rest request into a storage CLI management command, encapsulate the CLI management command in the SCSI instruction, and send the management command to the storage for execution in an in-band manner. In this embodiment, in step 104, sending the management instruction to the target storage cluster based on the target FC channel includes: generating a SCSI instruction based on the identifier of the target storage cluster and the management instruction; sending the SCSI instruction to the target storage cluster through the target FC channel.

[0053] In an embodiment of the present application, before step 101, the method for implementing an in-band management middleware for docking multiple storages provided by the present application further includes: obtaining the identifier of each FC channel and the identifier of the storage cluster corresponding to the FC channel; establishing a one-to-one corresponding relationship between the FC channel and the storage cluster.

[0054] Specifically, for example, taking the clusterId of the storage as the key and the name of the storage cluster corresponding to the FC channel as the value, and recording it in the memory for subsequent selection of the FC channel. The format is as follows:

[0055]

[0056] In an embodiment of the present application, before step 101, the method for implementing an in-band management middleware for docking multiple storages provided by the present application further includes: obtaining the identifier of each storage cluster; converting the identifier of each storage cluster into storage cluster information; establishing a one-to-one corresponding relationship between the identifier of the storage cluster and the storage cluster information.

[0057] Specifically, for example, traverse each storage cluster to obtain the identifier corresponding to each storage cluster, such as the WWID, which can be obtained by executing the following command: / lib / udev / scsi_id -g –page=0x83 / dev / sdx (where sdx represents the sd device, i.e., the name of the storage cluster).

[0058] Convert the WWID of the storage cluster to the clusterId of the storage cluster, and the method is as follows:

[0059] ClusterId = hex(WWID) >> 58 & hex(3FFFFFFFFFF)

[0060] Thus, a one-to-one correspondence is established between the identifier of the storage cluster, i.e., the WWID, and the storage cluster information, i.e., the clusterId.

[0061] In an embodiment of the present application, the management instruction is a Rest request sent by the upper-layer application.

[0062] Specifically, the in-band management middleware is used to provide a Rest interface for the upper-layer application, convert the Rest request into a storage CLI management command, encapsulate the CLI management command in a SCSI instruction, and send the management command to the storage for execution in an in-band manner. In this embodiment, the management instruction in step 101 above is a Rest request sent by the upper-layer application.

[0063] In an embodiment of the present application, generating a SCSI instruction based on the identifier of the target storage cluster and the management instruction in step 1041 includes: converting the management instruction into a storage CLI management command based on the identifier of the target storage cluster, and generating a SCSI instruction based on the storage CLI management command.

[0064] Specifically, the in-band management middleware is used to provide a Rest interface for the upper-layer application, convert the Rest request into a storage CLI management command, encapsulate the CLI management command in a SCSI instruction, and send the management command to the storage for execution in an in-band manner. In this embodiment, generating a SCSI instruction based on the identifier of the target storage cluster and the management instruction in step 1041 includes: converting the management instruction into a storage CLI management command based on the identifier of the target storage cluster, and generating a SCSI instruction based on the storage CLI management command.

[0065] In an embodiment of the present application, sending a SCSI instruction to the target storage cluster through the target FC channel in step 1042 includes: traversing the FC channel volume list to identify the target FC channel, sending a SCSI instruction to the target storage cluster, and recording the name of the target FC channel.

[0066] Specifically, in the above step 1042, sending SCSI commands to the target storage cluster through the target FC channel includes: traversing the FC channel volume list to identify the target FC channel, sending SCSI commands to the target storage cluster, and recording the name of the target FC channel. For example, traverse the FC channel volume list, send SCSI commands from the first FC channel. If the sending is unsuccessful, use the second FC channel to send SCSI commands until the sending is successful. And record the name of the FC channel volume that is finally sent successfully.

[0067] Based on the above embodiments, in a specific implementation manner of the present application, the embodiment of the present application provides a method for implementing an in-band management middleware for docking multiple storages, including the following steps:

[0068] Step 1: Preparation

[0069] When the user uses in-band management, they need to create a host of inbandmanagement type in the storage through the storage management interface in advance and add the port information of the FC HBA card in the host.

[0070] Then discover devices on the host side, the method is as follows: log in to the server, scan through the command echo '---' > / sys / class / scsi_host / ${hostName} / device / scsi_host / ${hostName} / scan, and path devices can be found in the directory / dev / disk / by-path / . Suppose there are four physical links between the host and the storage, then the storage has four FC channels, and each channel is an sd device (i.e., a storage cluster) on the host side. For example: / dev / sdb, / dev / sdc, / dev / sdd, and / dev / sde. And the sizes of these sd devices are fixed at 512B.

[0071] Step 2: Grouping of FC channels

[0072] When the in-band management middleware starts, it will automatically scan all sd devices (storage devices) in the / dev directory and group the sd devices according to the following rules.

[0073] Step 2.1: Filter out sd devices whose sizes are not 512B.

[0074] Step 2.2: Traverse the remaining sd devices in 1.1, obtain the WWID corresponding to each storage device, which can be obtained by executing the following command: / lib / udev / scsi_id -g –page = 0x83 / dev / sdx (where sdx represents the name of the sd device)

[0075] Step 2.3: Convert the WWID of the device to the clusterId of the storage cluster as follows:

[0076] ClusterId = hex(WWID) >> 58 & hex(3FFFFFFFFFF)

[0077] Note: The conversion rules provided by different storage vendors are inconsistent.

[0078] Step 2.4: Use the stored clusterId as the key and the name of the sd device corresponding to the FC channel as the value, and record it in memory for use when selecting the FC channel later. The format is as follows:

[0079]

[0080] Step 3: Selection of FC channels

[0081] Step 3.1: Add a parameter clusterID to the Rest interface. This parameter is used to indicate which storage execution the upper-layer application hopes to send the management execution to. This parameter is required. If the upper-layer application does not pass this parameter when calling the Rest interface, the Rest request call fails.

[0082] Step 3.2: After the in-band management middleware receives the Rest request, parse the clusterID parameter in the header to obtain the ID of the cluster. Obtain the corresponding FC channel list according to the clusterID.

[0083] Step 3.3: Convert the Rest request into a storage CLI command and encapsulate it as a SCSI instruction.

[0084] Step 3.4: Traverse the FC channel volume list, send the SCSI instruction from the first FC channel. If the sending is unsuccessful, use the second FC channel to send the SCSI instruction until the sending is successful. And record the name of the FC channel volume that is finally sent successfully.

[0085] It can be seen that in the embodiment of the present application, the in-band management middleware can identify the managed FC channel, obtain the WWID corresponding to the FC channel through the SCSI instruction, and obtain the identifier of the storage cluster corresponding to the channel according to the WWID. According to the identifier of the cluster and the name of the FC channel, maintain the corresponding relationship between the storage cluster and the FC channel in memory. After receiving the management request sent by the upper-layer application, it can identify the storage cluster to which the management request needs to be sent, and find the FC channel corresponding to the storage cluster according to the grouping information. Send the management request to the storage device through the SCSI instruction. Finally, it is realized that one in-band management middleware can be docked with multiple sets of storage clusters.

[0086] According to an embodiment of the present application, the in-band management middleware provided by the present application can identify the management FC channels, group the FC channels, and record the corresponding relationship between the storage clusters and the FC channels in the memory. After receiving the management request sent by the upper-layer application, it can identify the storage cluster to which the management request needs to be sent, and find the FC channel corresponding to the storage cluster according to the grouping information. The management request is sent to the storage device through SCSI commands. Finally, an in-band management middleware can be docked with multiple sets of storage clusters.

[0087] It should be understood that although Figure 1 the steps in the flowchart are shown in sequence according to the indication of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear description in the present application, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, Figure 1 at least a part of the steps in

It is possible to identify and manage the FC channel.

According to the identifier of the cluster and the name of the FC channel, the corresponding relationship between the storage cluster and the FC channel is maintained in the memory.
