本申请要求于2021年12月31日提交中国专利局,申请号为202111678634.9,申请名称为“一种主机与存储系统的通信连接方法、装置、设备及介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese patent application submitted to the China Patent Office on December 31, 2021 with the application number 202111678634.9. The entire contents are incorporated by reference in this application.
本申请涉及服务器技术领域,特别涉及一种主机与存储系统的通信连接方法、装置、设备及介质。The present application relates to the technical field of servers, and in particular to a communication connection method, device, equipment and medium between a host and a storage system.
NVMe(Non Volatile Memory express,非易失性内存主机控制器接口规范)存在超时机制不完善的问题,也即,主机在与NVMeoFC(NVMe over Fibre Channel,通过光纤网络实现NVMe传输)存储系统建立通信连接时,会存在概率性连接失败的问题。其中,主机自动连接NVMeoFC存储系统的原理是:主机与NVMeoFC存储系统建立端口连接时,会判断NVMeoFC存储系统上的端口是否具备discovery能力,如果NVMeoFC存储系统的端口具有discovery能力则会触发udev(设备管理器)。在此情况下,主机就会向NVMeoFC存储系统发送相关的链路信息,并由预先配置的规则文件触发nvme命令自动完成与NVMeoFC存储系统的连接。NVMe (Non Volatile Memory express, non-volatile memory host controller interface specification) has an imperfect timeout mechanism, that is, the host is establishing communication with the NVMeoFC (NVMe over Fiber Channel, NVMe transmission through the fiber network) storage system When connecting, there will be a problem of probabilistic connection failure. Among them, the principle of the host automatically connecting to the NVMeoFC storage system is: when the host establishes a port connection with the NVMeoFC storage system, it will judge whether the port on the NVMeoFC storage system has the discovery capability. If the port of the NVMeoFC storage system has the discovery capability, it will trigger udev(device manager). In this case, the host will send relevant link information to the NVMeoFC storage system, and the pre-configured rule file will trigger the nvme command to automatically complete the connection with the NVMeoFC storage system.
从上述过程可以看出主机自动连接NVMeoFC存储系统的过程依赖于端口触发udev进行通信连接的问题。发明人意识到,如果NVMeoFC存储系统在建立端口连接时由于异常原因导致NVMeoFC存储系统无法提供NVMe连接服务,即使NVMeoFC存储系统恢复正常,主机也无法与NVMeoFC存储系统建立通信连接。很显然,这样就无法保证主机在与NVMeoFC存储系统建立通信连接时的可靠性。目前,针对这一技术问题还没有较为有效的解决办法。From the above process, it can be seen that the process of the host automatically connecting to the NVMeoFC storage system depends on the problem that the port triggers udev for communication connection. The inventor realized that if the NVMeoFC storage system fails to provide NVMe connection services due to abnormal reasons when the NVMeoFC storage system establishes a port connection, even if the NVMeoFC storage system returns to normal, the host cannot establish a communication connection with the NVMeoFC storage system. Obviously, this cannot guarantee the reliability of the host when establishing a communication connection with the NVMeoFC storage system. Currently, there is no effective solution to this technical problem.

Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
请参见图1,图1为本申请实施例所提供的一种主机与存储系统的通信连接方法的流程图,该方法包括:Please refer to FIG. 1. FIG. 1 is a flow chart of a communication connection method between a host and a storage system provided in an embodiment of the present application. The method includes:
步骤S11:响应于NVMeoFC存储系统的配置信息发生变化,获取NVMeoFC存储系统中配置信息发生变化的变更配置信息;Step S11: In response to changes in the configuration information of the NVMeoFC storage system, obtain changed configuration information in which the configuration information in the NVMeoFC storage system has changed;
步骤S12:根据变更配置信息确定NVMeoFC存储系统中配置信息发生变化的目标主机;Step S12: Determine the target host whose configuration information changes in the NVMeoFC storage system according to the changed configuration information;
步骤S13:响应于目标主机已在带外管理服务器中进行注册,将变更配置信息中与目标主机相对应的目标配置信息发送至目标主机,以使目标主机与NVMeoFC存储系统建立通信连接。Step S13: In response to the target host being registered in the out-of-band management server, the target configuration information corresponding to the target host in the changed configuration information is sent to the target host, so that the target host establishes a communication connection with the NVMeoFC storage system.
在本实施例中,是提供了一种主机与存储系统的通信连接方法,通过该方法能够保证主机在与NVMeoFC存储系统建立通信连接时的可靠性。该通信连接方法是以带外管理服务器为执行主体进行具体说明。In this embodiment, a communication connection method between a host and a storage system is provided, through which the reliability of the host when establishing a communication connection with the NVMeoFC storage system can be guaranteed. The communication connection method is specifically described with the out-of-band management server as the execution subject.
具体的,当NVMeoFC存储系统中新增加了允许访问的主机、命名空间或者是NVMeoFC存储系统在当前时刻无法向访问主机提供NVMeoFC服务时,就会导致NVMeoFC存储系统的配置信息发生变化,在此情况下,带外管理服务器就会从NVMeoFC存储系统中获取配置信息发生变化的变更配置信息。Specifically, when a new host or namespace that allows access is added to the NVMeoFC storage system, or the NVMeoFC storage system cannot provide NVMeoFC services to the accessing host at the current moment, the configuration information of the NVMeoFC storage system will change. In this case Next, the out-of-band management server will obtain the changed configuration information of the changed configuration information from the NVMeoFC storage system.
当带外管理服务器获取得到NVMeoFC存储系统中配置信息发生变化的变更配置信息时,带外管理服务器会根据变更配置信息来确定NVMeoFC存储系统中配置信息发生变化的目标主机,并会检测目标主机是否在带外管理服务器上进行注册。When the out-of-band management server obtains the change configuration information that the configuration information in the NVMeoFC storage system changes, the out-of-band management server will determine the target host where the configuration information in the NVMeoFC storage system changes according to the change configuration information, and will detect whether the target host is Register on the out-of-band management server.
需要说明的是,NVMeoFC存储系统中配置信息发生授权变化的主机既可以是一个,也可以是多个。因此,目标主机的数量既可以是一个,也可以是多个,此处不作具体限定。It should be noted that, in the NVMeoFC storage system, there may be one or more hosts whose configuration information undergoes authorized changes. Therefore, the number of target hosts may be one or multiple, which is not specifically limited here.
如果目标主机已经在带外管理服务器中进行了注册,则带外管理服务器会将变更配置信息中与目标主机相对应的目标配置信息发送至目标主机;目标主机在接收到带外管理服务器所发送的与目标主机相对应的目标配置信息时,就会判断目标主机是否与NVMeoFC存储系统建立通信连接;如果目标主机与NVMeoFC存储系统建立了通信连接,则目标主机无需进行任何动作;如果目标主机与NVMeoFC存储系统未建立通信连接, 则目标主机会通过目标配置信息与NVMeoFC存储系统建立通信连接。If the target host has been registered in the out-of-band management server, the out-of-band management server will send the target configuration information corresponding to the target host in the change configuration information to the target host; When the target configuration information corresponding to the target host is configured, it will be determined whether the target host has established a communication connection with the NVMeoFC storage system; if the target host has established a communication connection with the NVMeoFC storage system, the target host does not need to take any action; If the NVMeoFC storage system has not established a communication connection, the target host will establish a communication connection with the NVMeoFC storage system through the target configuration information.
可见,在本实施例中,当NVMeoFC存储系统的配置信息发生变化时,带外管理服务器会获取NVMeoFC存储系统中配置信息发生变化的变更配置信息,并根据变更配置信息确定NVMeoFC存储系统中配置信息发生变化的目标主机;如果目标主机已经在带外管理服务器中进行了注册,则将变更配置信息中与目标主机相对应的目标配置信息发送至目标主机,从而使得目标主机与NVMeoFC存储系统建立通信连接。相较于现有技术而言,由于该方法是利用带外管理服务器来获取NVMeoFC存储系统中配置信息发生变化的变更配置信息,并将变更配置信息中与目标主机相对应的目标配置信息发送至目标主机,从而建立目标主机与NVMeoFC存储系统之间的通信连接。无需依赖端口触发udve来建立主机与NVMeoFC存储系统之间的通信连接,这样就可以进一步确保主机在与NVMeoFC存储系统建立通信连接时的可靠性。It can be seen that in this embodiment, when the configuration information of the NVMeoFC storage system changes, the out-of-band management server will obtain the changed configuration information of the changed configuration information in the NVMeoFC storage system, and determine the configuration information in the NVMeoFC storage system according to the changed configuration information The changed target host; if the target host has been registered in the out-of-band management server, the target configuration information corresponding to the target host in the changed configuration information is sent to the target host, so that the target host establishes communication with the NVMeoFC storage system connect. Compared with the prior art, since this method utilizes the out-of-band management server to obtain the changed configuration information in which the configuration information in the NVMeoFC storage system changes, and sends the target configuration information corresponding to the target host in the changed configuration information to The target host, so as to establish a communication connection between the target host and the NVMeoFC storage system. There is no need to rely on port trigger udve to establish a communication connection between the host and the NVMeoFC storage system, so that the reliability of the host when establishing a communication connection with the NVMeoFC storage system can be further ensured.
基于上述实施例,本实施例对技术方案作进一步的说明与优化,作为一种优选的实施方式,上述步骤:当NVMeoFC存储系统的配置信息发生变化时,则获取NVMeoFC存储系统中配置信息发生变化的变更配置信息的过程,包括:Based on the above embodiments, this embodiment further explains and optimizes the technical solution. As a preferred implementation, the above steps: when the configuration information of the NVMeoFC storage system changes, obtain the configuration information in the NVMeoFC storage system. The process of changing configuration information, including:
利用预先添加在NVMeoFC存储系统中的状态变更程序模块对NVMeoFC存储系统的配置信息进行实时监测;Real-time monitoring of the configuration information of the NVMeoFC storage system by using the state change program module pre-added in the NVMeoFC storage system;
响应于NVMeoFC存储系统的配置信息发生变化,通过状态变更程序模块获取NVMeoFC存储系统中配置信息发生变化的变更配置信息。In response to changes in the configuration information of the NVMeoFC storage system, the change configuration information of the changes in the configuration information in the NVMeoFC storage system is acquired through the state change program module.
在本实施例中,为了保证带外管理服务器能够获取得到NVMeoFC存储系统中配置信息发生变化的变更配置信息,是预先在NVMeoFC存储系统中添加了状态变更程序模块,并利用状态变更程序模块来实时监测NVMeoFC存储系统中配置信息的变化。如果NVMeoFC存储系统中的配置信息发生了变化,状态变更程序模块则会在第一时间将NVMeoFC存储系统中配置信息发生变化的变更配置信息发送至带外管理服务器。In this embodiment, in order to ensure that the out-of-band management server can obtain the changed configuration information of the changed configuration information in the NVMeoFC storage system, a state change program module is added to the NVMeoFC storage system in advance, and the state change program module is used to real-time Monitor configuration information changes in the NVMeoFC storage system. If the configuration information in the NVMeoFC storage system changes, the status change program module will immediately send the changed configuration information of the configuration information in the NVMeoFC storage system to the out-of-band management server.
可以理解的是,当NVMeoFC存储系统的配置信息发生变化时,有可能是在NVMeoFC存储系统中新增加了可以授权访问的主机、或者是在NVMeoFC存储系统中新增加了命名空间,还有可能是NVMeoFC存储系统中各个端口之间的配对情况发生了变化。因此,在本实施例中,当状态变更程序模块检测到NVMeoFC存储系统的配置信息发生变化时,状态变更程序模块会将NVMeoFC存储系统的NQN(NVMe Qualified Name,NVMe中的限定名称)、NVMeoFC存储系统中配置信息发生变化主机的NQN以及NVMeoFC存储系统中端口配对发生变化的目标端口配对信息全部打包发送至带外管理服 务器。It is understandable that when the configuration information of the NVMeoFC storage system changes, it may be that a new host that can be authorized to access is added to the NVMeoFC storage system, or a new namespace is added to the NVMeoFC storage system, or it may be The pairing between individual ports in the NVMeoFC storage system has changed. Therefore, in this embodiment, when the state change program module detects that the configuration information of the NVMeoFC storage system changes, the state change program module will store the NQN (NVMe Qualified Name, NVMe Qualified Name) and NVMeoFC storage system of the NVMeoFC storage system. When the configuration information in the system changes, the NQN of the host and the target port pairing information of the changed port pairing in the NVMeoFC storage system are all packaged and sent to the out-of-band management server.
基于上述实施例,本实施例对技术方案作进一步的说明与优化,作为一种优选的实施方式,上述通信连接方法还包括:Based on the above-mentioned embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation mode, the above-mentioned communication connection method also includes:
响应于目标主机未在带外管理服务器中进行注册,判定目标主机出现异常,并提示预警信息。In response to the fact that the target host is not registered in the out-of-band management server, it is determined that the target host is abnormal, and an early warning message is prompted.
在实际应用中,如果目标主机未在带外管理服务器中进行注册,则说明目标主机出现了异常,在此情况下,带外管理服务器就会提示预警信息。能够想到的是,通过这样的设置方式就可以及时提醒维修人员来对目标主机进行检测与维修,由此就可以降低或避免用户在遭受异常情形时所带来的经济损失。In practical applications, if the target host is not registered in the out-of-band management server, it means that the target host is abnormal. In this case, the out-of-band management server will prompt an early warning message. It is conceivable that through such a setting method, the maintenance personnel can be reminded in time to detect and repair the target host, thereby reducing or avoiding the economic loss caused by the user when encountering an abnormal situation.
基于上述实施例,本实施例对技术方案作进一步的说明与优化,作为一种优选的实施方式,上述通信连接方法还包括:Based on the above-mentioned embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation mode, the above-mentioned communication connection method also includes:
预先在目标主机上添加状态订阅程序模块,并利用状态订阅程序模块将目标主机的NQN注册至带外管理服务器。Add a status subscription program module on the target host in advance, and use the status subscription program module to register the NQN of the target host to the out-of-band management server.
在本实施例中,为了保证目标主机能够与NVMeoFC存储系统建立可靠的通信连接,还预先在目标主机上添加了状态订阅程序模块,并利用状态订阅程序模块来对目标主机与NVMeoFC存储系统的通信连接情况进行单独管理。具体的,当在目标主机上添加了状态订阅程序模块之后,状态订阅程序模块首先会将目标主机的NQN(NVMe Qualified Name,nvme限定名)注册到带外管理服务器中,并在带外管理服务器中存储目标主机的相关信息。In this embodiment, in order to ensure that the target host can establish a reliable communication connection with the NVMeoFC storage system, a status subscription program module is added to the target host in advance, and the status subscription program module is used to monitor the communication between the target host and the NVMeoFC storage system Connections are managed individually. Specifically, after adding the status subscription program module on the target host, the status subscription program module will first register the NQN (NVMe Qualified Name, nvme qualified name) of the target host to the out-of-band management server, and Information about the target host is stored in it.
作为一种优选的实施方式,上述步骤:将变更配置信息中与目标主机相对应的目标配置信息发送至目标主机的过程,包括:As a preferred implementation manner, the above step: the process of sending the target configuration information corresponding to the target host in the changed configuration information to the target host, including:
将变更配置信息中与目标主机相对应的目标配置信息发送至状态订阅程序模块,并利用状态订阅程序模块将目标配置信息发送至目标主机。Send the target configuration information corresponding to the target host in the changed configuration information to the status subscription program module, and use the status subscription program module to send the target configuration information to the target host.
为了提高目标主机的执行效率,在本实施例中,还利用状态订阅程序模块来接收带外管理服务器所发送的目标配置信息。当状态订阅程序模块接收到带外管理服务器所发送的目标配置信息时,就会将目标配置信息发送至目标主机,以使目标主机与NVMeoFC存储系统建立通信连接。In order to improve the execution efficiency of the target host, in this embodiment, the status subscription program module is also used to receive the target configuration information sent by the out-of-band management server. When the status subscription program module receives the target configuration information sent by the out-of-band management server, it will send the target configuration information to the target host, so that the target host can establish a communication connection with the NVMeoFC storage system.
作为一种优选的实施方式,上述通信连接方法还包括:As a preferred implementation manner, the above-mentioned communication connection method further includes:
利用状态订阅程序模块定期检测目标主机与NVMeoFC存储系统之间的通信连接状 态。Use the status subscription program module to periodically detect the communication connection status between the target host and the NVMeoFC storage system.
在实际应用中,目标主机上的状态订阅模块除了被动接收带外管理服务器所发送的目标配置信息之外,因为状态订阅模块中还存储有目标主机与NVMeoFC存储系统之间的通信连接信息,所以,还可以利用状态订阅模块来定期检测目标主机与NVMeoFC存储系统之间的通信连接状态。In practical applications, in addition to passively receiving the target configuration information sent by the out-of-band management server, the status subscription module on the target host also stores the communication connection information between the target host and the NVMeoFC storage system, so , the state subscription module can also be used to periodically detect the state of the communication connection between the target host and the NVMeoFC storage system.
也即,如果状态订阅程序模块检测到目标主机与NVMeoFC存储系统之间的通信连接状态发生中断,那么状态订阅程序模块就会通知目标主机与NVMeoFC存储系统再次建立通信连接。显然,通过本实施例所提供的技术方案,就可以进一步保证目标主机与NVMeoFC存储系统之间的可靠连接。That is, if the status subscription program module detects that the communication connection between the target host and the NVMeoFC storage system is interrupted, the status subscription program module will notify the target host to establish a communication connection with the NVMeoFC storage system again. Obviously, through the technical solution provided in this embodiment, the reliable connection between the target host and the NVMeoFC storage system can be further ensured.
请参见图2,图2为本申请实施例所提供的一种目标主机与NVMeoFC存储系统建立通信连接的示意图。其中,目标主机与NVMeoFC存储系统需要通过光纤建立通信连接,在目标主机和NVMeoFC存储系统中是分别设置有HBA(Host Bus Adapter,主机总线适配器)和FC端口(也即,图2中的N_Port)。Please refer to FIG. 2 .

在实际应用中,为了保证目标主机能够与NVMeoFC存储系统建立可靠的通信连接,需要预先在目标主机和NVMeoFC存储系统上分别添加状态订阅程序模块和状态变更程序模块。其中,状态订阅模块会将目标主机的NQN注册到带外管理服务器上,状态变更程序模块会对NVMeoFC存储系统的配置信息进行实时监测,如果状态变更程序模块检测到NVMeoFC存储系统的配置信息发生变化时,状态变更程序模块会将NVMeoFC存储系统中配置信息发生变化的变更配置信息发送至带外管理服务器。其中,NVMeoFC存储系统中配置信息发生变化的变更配置信息包括:NVMeoFC存储系统中新增授权主机的NQN、NVMeoFC存储系统的NQN以及授权主机与NVMeoFC存储系统之间配对端口的端口信息等等。In practical applications, in order to ensure that the target host can establish a reliable communication connection with the NVMeoFC storage system, it is necessary to add a status subscription program module and a status change program module on the target host and the NVMeoFC storage system respectively. Among them, the status subscription module will register the NQN of the target host to the out-of-band management server, and the status change program module will monitor the configuration information of the NVMeoFC storage system in real time. If the status change program module detects that the configuration information of the NVMeoFC storage system has changed , the state change program module will send the change configuration information that the configuration information in the NVMeoFC storage system changes to the out-of-band management server. Among them, the changed configuration information of the configuration information in the NVMeoFC storage system includes: the NQN of the newly authorized host in the NVMeoFC storage system, the NQN of the NVMeoFC storage system, and the port information of the paired port between the authorized host and the NVMeoFC storage system, etc.
当带外管理服务器接收到状态变更程序模块所发送的变更配置信息时,如果带外管理服务器确定出NVMeoFC存储系统中配置信息发生变化的目标主机已经在带外管理服务器中进行了注册,此时带外管理服务器就会将变更配置信息中与目标主机相对应的配置信息发送至目标主机,以使目标主机与NVMeoFC存储系统建立通信连接。When the out-of-band management server receives the change configuration information sent by the state change program module, if the out-of-band management server determines that the target host whose configuration information has changed in the NVMeoFC storage system has registered with the out-of-band management server, then The out-of-band management server will send the configuration information corresponding to the target host in the changed configuration information to the target host, so that the target host can establish a communication connection with the NVMeoFC storage system.
