Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
In the current big data era, massive data occupies a large amount of storage space. In order to ensure stable operation of upper-layer applications such as big data analysis and artificial intelligence, higher requirements are put forward on a data storage system, and particularly with the improvement of configuration of a host and storage hardware, how to improve the performance of the IPSAN is a technical problem to be solved urgently by technical personnel in the field. Based on this, the present application provides a session creation scheme, which can further determine the number of sessions of the target ISCSI service end and the number of sessions of the target ISCSI client after acquiring the session request, and create a session between the target ISCSI client and the target ISCSI service end when the numbers of sessions of the target ISCSI client and the target ISCSI client satisfy a preset condition, so as to improve data throughput and IPSAN performance.
Fig. 1 is a flowchart of a session creation method according to an embodiment of the present application. Referring to fig. 1, the session creation method includes:
s11: and acquiring a session request initiated by the target ISCSI client for establishing a session with the target ISCSI server.
In this embodiment, a session request initiated by a target ISCSI client to establish a session with a target ISCSI server is first obtained. The ISCSI service end (target), i.e. a server for storing the storage resources of the hard disk, can provide the available storage resources for the user, and the ISCSI client (initiator) is software used by the user to access the storage resources of the remote service end. The ISCSI service end can also be called a storage device, and the ISCSI client is correspondingly called a host system. The present embodiment improves ISCSI performance by increasing the number of sessions between the host and the storage. The target ISCSI client and the target ISCSI server are an ISCSI server and an ISCSI client which are about to establish a session. And one target ISCSI client corresponds to one unique IQN, and a session relation is established between the target ISCSI client and the target ISCSI server based on the IQN.
S12: determining a first number of ISCSI clients having a session relationship with the target ISCSI server and a second number of ISCSI servers having a session relationship with the target ISCSI client.
In this embodiment, after the session request is acquired, a first number of ISCSI clients having a session relationship with the target ISCSI client and a second number of ISCSI clients having a session relationship with the target ISCSI client are determined. Before that, a list including each ISCSI server and the ISCSI clients having session relationships with each ISCSI server is constructed to obtain an ISCSI server list. Further, after the session request is obtained, the first number of ISCSI clients having a session relationship with the target ISCSI server is found from the ISCSI server list. The second number of ISCSI service sides having a session relationship with the target ISCSI client may be determined by the number of sessions established by the corresponding IQN. Since the ISCSI service list is dynamically changed according to the number of sessions it establishes, it needs to have update capability. Specifically, an adding instruction for adding the ISCSI service end or the ISCSI client having a session relationship with the ISCSI service end in the ISCSI service end list is obtained, and the ISCSI service end list is updated according to the adding instruction. In this example, taking the MCS storage system as an example, as shown in fig. 2, when a host or an IQN is added, the storage PLIF module adds the host or the IQN to a host list, and sends the list to the ietd daemon. When the host initiates a login request, the IETD accepts the login request of the host, and searches the total login number of the host in which iqn is located in the host list, i.e. the first number in the above embodiment. Wherein, the PLIF module (Platform Interface) is an Interface module of the MCS storage system, and provides an Interface between a component and a driver.
S13: and judging whether the first quantity and the second quantity meet preset conditions, if so, establishing a session relationship between the target ISCSI client and the target ISCSI server according to the session request.
In this embodiment, after the first number and the second number are determined, it is determined whether the first number and the second number satisfy a preset condition, and if so, a session relationship is established between the target ISCSI client and the target ISCSI server according to the session request. Specifically, whether the first number is not larger than a first threshold value and whether the second number is not larger than a second threshold value is judged; the first threshold is the maximum number of sessions that the target ISCSI service end can establish, and the second threshold is the maximum number of sessions that the target ISCSI client can establish. If yes, establishing a session relation between the target ISCSI client and the target ISCSI server according to the session request, and if not, not responding to the session request. Considering that the performance of the hardware (CPU, memory, etc.) of the host device is more and more excellent, the hardware resources are fully utilized to exert the performance, and considering the requirements of using and storing other host hardware and the limitation of the resources at the back end of storage, reasonable limitation is required. Data throughput can be improved by increasing the number of sessions between the host and the storage, and the rapidity of data transmission is ensured to improve the IPSAN performance. Of course, the above is implemented under the condition that the maximum number of hosts and the maximum number of sessions allowed for storage are not changed, that is, the first threshold value is kept unchanged, and the second threshold value is expanded to increase the number of hosts and storage sessions to improve the performance of the IPSAN.
In this embodiment, in the MCS storage system, each ISCSI service end has at most 8 IQNs, and each IQN can establish at most 4 sessions. In this mode, the maximum number of sessions allowed for each ISCSI server is 32. The present embodiment will store the maximum number of connection sessions allowed to extend from 4 to 16 per IQN. The maximum number of sessions allowed by each ISCSI server is 32, and the rest specification parameters are also unchanged. Generally, each server corresponds to one IQN, and nowadays, the hardware configuration of a server host is higher and higher, and the performance of the server cannot be fully developed by 4 sessions. Data transfer rates between hosts and storage are increased by increasing the number of storage single server connections. The throughput of a single server and storage can be greatly improved by expanding the number of the servers to 16. When the user uses the system, if the maximum throughput of a single host needs to be exerted, a plurality of sessions can be established; if a plurality of hosts are required to be connected and stored, each host can reduce the number of connection sessions, so that more hosts can be logged in. That is, the maximum number of sessions that the target ISCSI service side can establish is 32, and the maximum number of sessions that the target ISCSI client side can establish is 16. If the host login number is less than 32 and the IQN login number is less than 16, the login is completed and the corresponding IQN login number is correspondingly increased, and if the host login number is greater than 32 or the IQN login number is greater than 16, the login of the IQN of the host is rejected. The IPSAN performance is improved by increasing the number of the host and the storage session, and meanwhile, the specification parameters of the IPSAN can be changed into configurable parameters, so that a user can configure according to the requirement of the user.
In this embodiment, in order to improve the fault tolerance in the session creation process, when a node fails, the session request may fail over (failover) to a normal node, so as to ensure that the normal node does not fail. The node can recover to the original session request after failure recovery (failback). Specifically, when the target ISCSI service end fails, a session relationship is established between the target ISCSI client and a backup service end corresponding to the target ISCSI service end according to the session request through a failover operation mode; and when the target ISCSI server side is in failure relief, performing failure recovery operation. It is understood that if the dual-control storage system fails over, the storage node of fail will register in the node of normal. In this embodiment, statistics of login of the fail node is also added to the ietd daemon module, and if the total login data of the normal node and the fail node is greater than 32, login behind the fail node is stopped. And the fail node will recover to the original login number at the time of failback.
Therefore, the embodiment of the application firstly acquires a session request which is initiated by a target ISCSI client and establishes a session with a target ISCSI server; then determining a first number of ISCSI clients having a session relationship with the target ISCSI server and a second number of ISCSI servers having a session relationship with the target ISCSI clients; and finally, judging whether the first quantity and the second quantity meet preset conditions, if so, establishing a session relationship between the target ISCSI client and the target ISCSI server according to the session request. After the session request is acquired, the session number of the target ISCSI client and the session number of the target ISCSI server are further determined, and when the session numbers of the target ISCSI client and the target ISCSI client meet preset conditions, a session is established between the target ISCSI client and the target ISCSI server, so that data throughput and IPSAN performance are improved.
