Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.

The core of the invention is to provide a service processing method, a device, equipment and a medium, so as to solve the technical problem that the throughput of the original service of a standby controller cannot be maintained after path transfer in the current dual controller, so that the service processing capacity is reduced.

In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In the path transfer process of the dual controller, the host cannot sense the path change, the WWPN on the port of the host or the server and the WWPN on the storage port can uniquely determine one path, one physical port can be provided with a plurality of virtual ports, each virtual port is provided with one WWPN, and one stored physical port can generate a plurality of paths with one physical port of the host or the server. FIG. 2 is a schematic diagram of another path transfer of the current dual controller, as shown in FIG. 2, a node A (standby control node 10) has one physical port including two virtual ports, namely a virtual port 1 and a virtual port 2, wherein traffic of the virtual port 1 and the virtual port 2 is polled and processed by a traffic processing thread, the physical port of the node A is connected with a host/server for processing the host/server traffic, the virtual port 2 is used for port redundancy, and the traffic of the virtual port 1 of the node B is taken over when the node B (fault control node 9) fails; the node B has a physical port comprising two virtual ports, namely a virtual port 1 and a virtual port 2, wherein the services of the virtual port 1 and the virtual port 2 are polled and processed by a service processing thread, the physical port of the node B is connected with a host/server 8 and is used for processing the services of the host/server 8, and the virtual port 2 is used for carrying out port redundancy.

After the node B fails, the node a virtual port 2 takes over the WWPN of the node B virtual port 1, so that the link 2 is lost, a new link 3 is established between the host/server and the node a virtual port 2, and the traffic on the link 2 is naturally transferred to the link 3, so that the host traffic cannot be stopped due to the loss of the link 2. The specific transfer process host port WWPN is assumed to be WWPN-h, the WWPN on the A node virtual port 1 is assumed to be WWPN-a, the WWPN on the B node virtual port 1 is assumed to be WWPN-B, WWPN-h forms a link 1 with WWPN-a, WWPN-h forms a link 2 with WWPN-B, WWPN-B transfers to the A node virtual port 2 from the B node virtual port 1 after the B node fails, WWPN-B and WWPN-h form a new link 3, and thus the logic path between the host port WWPN-h and the storage node WWPN-B is not changed, but the physical position is changed.

In the above process, each service thread runs on one CPU core, and when the service load on link 1 and link 3 becomes large, the processing load of the CPU core becomes large, and at this time, node a cannot maintain the original service throughput, and as a whole, the stored service processing capacity decreases due to node B failure. The business processing method provided by the invention can solve the current technical problems.

Fig. 3 is a flowchart of a service processing method according to an embodiment of the present invention, where, as shown in fig. 3, the method is applied to a storage system of a dual control node, and includes:

s11: under the condition that the service corresponding to the fault control node is transferred to the standby control node, acquiring service data of a service thread, each target virtual port of the standby control node and each current central processing unit core;

s12: uniformly distributing each target virtual port to a corresponding target central processing unit core in each current central processing unit core;

the number of the target central processing unit cores is a plurality of;

s13: according to the service balance processing mechanism, distributing service data to the corresponding target central processing unit core in a balanced manner to perform service processing;

the service balance processing mechanism is determined based on the serial number property of the service data and/or the utilization rate of each target central processing unit core.

Specifically, the invention is applied to a storage system with double control nodes, the double control redundancy mode corresponding to the double control nodes is not limited, and the double control redundancy mode can be a mutual standby mode or a double active mode and can be set according to actual conditions. The mutual backup mode is that two controllers are both active, one controller takes over after failure, and the mutual backup controllers of the respective controllers are formed. The dual active mode balances the load of the system with the granularity of Input Output (IO), and the situation that one controller is busy and the other controller is idle, so that the load of one controller is far higher than that of the other controller can not occur.

In the service transfer process, when the link is changed, the standby control node can leave a certain virtual port for the fault control node so as to be convenient for transfer, for example, 10 virtual ports are arranged in the standby control node, the link actually occupies 5 virtual ports at most, and the other 5 ports are virtual ports prepared for the fault control node. Similarly, the fault control node is the same as the virtual port setting process. The two control nodes have common cluster data and are synchronized in real time.

In this embodiment, the service corresponding to the failure control node is transferred to the backup control node, regardless of which controller is specifically the failure control node and which controller is the backup control node, and the node a may be the failure control node or the node B may be the failure control node. The transition is made as long as the failed control node is not operational. It should be noted that, in this embodiment, the transfer path and load balancing between the CPU core and the service thread in the service processing process are independent from each other. And under the condition of transferring to the standby control node, acquiring service data of the service thread, each target virtual port of the standby control node and each current central processing unit core.

The service data is a series of logic operations for processing read/write instructions of a host or a server, and can be that one write operation is completed, one service processing is completed, and one read operation is completed, and one service processing is completed. For example, one CPU core includes 3 services, service 1: acquiring a host read-write instruction from a driving buffer area; service 2: analyzing the instruction content, such as analyzing the logic address of the read-write instruction, and reading the length of the write data; service 3: if the command is a read command, the data needs to be sent to the host from the local memory, and if the command is a write command, the data of the host needs to be written into the memory.

Each target virtual port of the standby control node can be all virtual ports in the standby control node; the virtual port formed by the occupied link may also include an original virtual port in the standby control node and a virtual port transferred to the standby control node by the fault control node, which is not limited herein and may be set according to actual conditions.

The current CPU cores may be all CPU cores of the controller where the standby control node is located, may be CPU cores only responsible for service processing and other processing (such as system processing), and the like, and are not limited herein, and may be set in actual situations.

In step S12, each target virtual port is uniformly distributed to the corresponding target CPU core in each current CPU core, and it can be understood that the number of target CPU cores is plural, so as to distinguish that the path transfer under the current dual controller only processes the service thread in one CPU core. In this embodiment, the balanced allocation may be an average allocation, or may be a determination of a corresponding target CPU core based on a certain balanced algorithm, where the current number of CPU cores is greater than or equal to the target CPU core. The purpose of the balanced allocation in step S12 is to ensure that each target virtual port corresponds to each target CPU core, and to avoid that all target virtual ports correspond to only one target CPU core. One target CPU core in this embodiment may correspond to one target virtual port, or may correspond to a plurality of target virtual ports.

The balanced allocation in step S13 is based on specific service data allocation, and the service data in this embodiment is flexibly processed, and after a certain service data is issued, allocation is performed to realize flexible allocation. Instead of the mapping relation of the service data and the virtual port firstly achieving an agreement, the mapping relation between each virtual port and the CPU core is considered, and then the mapping relation between the service data and the CPU core is considered and issued.

The service balancing processing mechanism in this embodiment may be based on the serial number property of the service data, the usage rate of each target CPU core, or a combination of both, or may be determined by other reference data besides the two, which is not limited herein.

The nature of the serial numbers of the corresponding disks on the host, such as E-disk and F-disk, is that the host names the disks, and in this embodiment, the serial numbers of the corresponding virtual disks on the storage device are based on the internal numbers of the corresponding virtual disks, and in general, the storage device can provide 2048 virtual disks to one host at most, the number of which is far greater than the number of CPU cores, and at this time, it needs to determine which CPU core the data (service data) of the virtual disk is processed by to balance the CPU load, so that the CPU cores are balanced for use. The corresponding drop number may be 0-2047, which CPU core is to be processed based on the nature of the number.

The usage rate of the target CPU cores is plural, and considering the balancing processing, the usage rate needs to be considered, if the difference between the usage rates is small, it is indicated that the current target CPU cores reach the balancing, and if the difference between the usage rates is large, it is indicated that the current target CPU cores do not reach the balancing, and it is necessary to fill the specific target CPU cores which do not reach the balancing based on the current service data. The specific balanced distribution can be the same as or different from the above balanced distribution processing procedure, and a new balanced processing algorithm can be used to determine a corresponding target CPU core so as to facilitate service processing.

The service processing method provided by the embodiment of the invention is applied to a storage system of double control nodes, and under the condition that the service of a fault control node is transferred to a standby control node, target virtual ports are uniformly distributed to corresponding target CPU cores in each current CPU core of the standby control node to serve as first uniform distribution; and then, according to a service balance processing mechanism, distributing the service data to the corresponding target service processor core in a balance mode to perform service processing, wherein the service data is used as balance processing of the second central processor core. The method has the advantages that the first balanced distribution ensures the balanced processing of the service thread corresponding to the virtual port in the CPU core, and the second balanced distribution ensures the balanced processing of the service data corresponding to the CPU core under the service thread. The twice balancing processing process avoids the condition that the load caused by the current path transfer of the double controllers is increased only on one CPU core, and simultaneously enables the original service and the transferred service on the standby control node to be balanced in load processing, and ensures the improvement of the service processing capacity and the improvement of the service throughput by fully utilizing CPU resources under the condition of ensuring the normal processing of the service of the fault control node.

Based on the above embodiments, in some embodiments, the balancing the allocation of each target virtual port to the corresponding target cpu core in each current cpu core in step S12 includes:

performing remainder processing on the total number of the current central processing unit cores by the serial numbers of the target virtual ports to determine remainder corresponding to the serial numbers of the target virtual ports;

Specifically, the numbers are respectively based on each target virtual port and each current CPU core, wherein the numbers are that the target virtual port starts numbering from 0, and the current CPU core starts numbering from 0, and the two are independent from each other. And performing remainder processing on the total number of the current CPU cores by the numbers of the target virtual ports to determine corresponding remainder, and matching the specific number of the remainder to the number of each current CPU core so as to finish matching to the corresponding target CPU cores.

For example, the number of the target virtual port is 5, the total number of the current CPU cores is 3, the remainder obtained by taking the remainder is 2, and the target virtual port is matched to the current CPU core with the number of 2.

The virtual port and the CPU core are balanced and matched so as to facilitate the creation of a corresponding mapping mechanism, ensure the balance of the CPU cores in the subsequent service processing process and avoid the condition of high load pressure caused by processing concentrated in one CPU core.

In some embodiments, the service balancing processing mechanism determines based on the nature of the landing number of the service data, and in step S13, the service balancing processing mechanism distributes the service data to the corresponding target central processing unit core for service processing, including:

obtaining a virtual disk number corresponding to the service data, wherein the virtual disk number is distinguished from a disk number corresponding to the host;

performing remainder processing on the total number of the target CPU cores by each virtual disk number to determine a remainder corresponding to each virtual disk number;

Specifically, the service balancing processing mechanism only determines by the serial number property of the dropped disc of the service data, obtains the serial number of the virtual disc corresponding to the service data, and at this time, the serial number of the virtual disc is distinguished from the serial number of the corresponding disc of the host, for example, the service data of a plurality of virtual discs are provided for the host, the serial number of the virtual disc from 0 needs to be obtained, and the serial number is carried out on the target CPU core, so that the serial number and the virtual disc serial number are independent serial numbers.

And performing remainder processing on the total number of the target CPU cores by each virtual disk number to determine a remainder corresponding to each virtual disk number, and matching each remainder to the number of each target CPU core to determine matching to the corresponding target CPU core. The remainder processing in this embodiment is the same as that of the virtual port, and will not be described here.

In some embodiments, the service balancing processing mechanism is determined based on the usage rate of the central processing unit core, and the service balancing processing mechanism distributes service data to the corresponding target central processing unit core for service processing, including:

acquiring the utilization rate of each target central processing unit core;

determining a difference between the maximum usage and the minimum usage;

judging whether the difference value is larger than a difference value threshold value or not;

if the service data is larger than the minimum utilization rate, distributing the service data to a target central processing unit core corresponding to the minimum utilization rate for service processing.

Specifically, the usage rate of each target CPU core will have a difference, so that the balance degree of each target CPU core can be determined by using the parameter of the usage rate, if the usage rate has a larger difference, the corresponding balance degree of each target CPU core is worse, and the service data issued needs to be distributed to the corresponding target CPU core with worse balance degree to ensure balanced distribution, so that the balance of the usage rate of each target CPU core is achieved, and the difference is reduced.

The target CPU cores corresponding to the maximum usage rate and the minimum usage rate may be obtained by a sorting method or a screening method, and the present invention is not limited thereto. The acquisition of the corresponding ordering method may be such that the ordering of the usage rate of each target CPU core from large to small or from small to large is not limited, and may be set according to the actual setting. The difference threshold in this embodiment may be determined based on an algorithm, or may be determined by parameters such as a time difference value of completion of the same task in the service processing process, which is not limited herein.

In this embodiment, the determination of the balance of the usage rates of the target CPU cores is determined based on the difference between the maximum usage rate and the minimum usage rate, and if the difference is greater than the difference threshold, it is indicated that the usage rates of the two corresponding target CPU cores differ greatly, resulting in an excessive balance, so that service data needs to be distributed to the target CPU core corresponding to the minimum usage rate for service processing.

When the difference is smaller than or equal to the difference threshold, it is indicated that the current usage rate of each target CPU core is smaller and approximately equal, and therefore, other balanced allocation methods may be adopted.

In some embodiments, the service balancing processing mechanism determines, based on the disk number property of the service data and the usage rate of each target central processing unit core, to perform service processing on the service data distributed to the corresponding target central processing unit core according to the service balancing processing mechanism, including:

acquiring the utilization rate of each target central processing unit core;

determining a difference between the maximum usage and the minimum usage;

if the service data is larger than the service data, the virtual disk corresponding to the service data is dropped to a target central processing unit core corresponding to the minimum utilization rate;

if not, obtaining a virtual disk number corresponding to the service data, wherein the virtual disk number is distinguished from a disk number corresponding to the host;

Specifically, in the case that the difference is not greater than the difference threshold, a remainder processing manner may be used, and the corresponding specific manner is the same as the remainder manner of the virtual disc number, which is not described herein again, and may refer to the above embodiment.

The service balance processing mechanism is different in determining process, so that the corresponding balanced distribution modes for carrying out service processing on the service data to the corresponding target central processing unit cores according to the service balance processing mechanism are different, diversity and flexibility of balanced distribution are realized, and load balance of each target CPU core is ensured.

On the basis of the above embodiments, in some embodiments, a transfer determining process for transferring the service corresponding to the failure control node in step S11 to the standby control node includes:

obtaining virtual ports of a fault control node, virtual ports to be transferred of a standby control node and a port transfer list, wherein the port transfer list stores port mapping relations between the virtual ports of the fault control node and the virtual ports to be transferred of the standby control node;

and parallelly transferring links of the virtual ports of the fault control node to the virtual ports to be transferred of the corresponding standby control node according to the port transfer list.

It can be understood that the virtual port of the failure control node mainly refers to a virtual port corresponding to a link formed by the host and the failure control node, and the virtual port to be transferred of the standby control node is a receiving virtual port corresponding to the standby control node to which the service of the failure control node is to be transferred. And the port transfer list stores the port mapping relation between the virtual port of the fault control node and the virtual port to be transferred of the standby control node. The port map is a map under each virtual port stored in the dual controller in advance, and for example, virtual ports 2, 4, 6, and 8 of the control node a take over virtual ports 1, 3, 5, and 7 of the control node B, respectively, and the port map is formed in this way.

And the links of the virtual ports of the fault control node are respectively transferred to the virtual ports to be transferred of the corresponding standby control node in parallel based on the port transfer list, so that parallel processing of transfer paths is realized, and transfer time is saved.

In some embodiments, considering that the path transfer is not parallel to the above embodiment, the transfer determination process of transferring the traffic corresponding to the failure control node to the standby control node in step S12 may also be sequential transfer, including:

Acquiring a link priority corresponding to a virtual port of a fault control node, wherein the link priority is determined by the importance degree of a service thread accepted by the virtual port corresponding to the link of the fault control node;

and transferring the links of the virtual ports of the fault control node to the virtual ports to be transferred of the corresponding standby control node according to the port transfer list and the link priority.

Specifically, the link priority corresponding to the virtual port of the fault control node is obtained, where the link priority may be determined by the corresponding service thread priority, and in this embodiment, the service thread priority may be determined by the importance degree of the service thread, or may also be determined by the size of the occupied space of other service threads, which is not limited herein. The links of the virtual ports of the fault control node are transferred to the corresponding virtual ports with transfer based on the port transfer list and the link priority, that is, the links with higher priority are preferentially transferred through the link priority, and then the links with lower priority are transferred, so that the order of the link transfer is realized.

In the link transfer process provided by the embodiment, the corresponding parallel transfer can save transfer time, and the order of the link transfer is realized according to the transfer sequence of the link priority.

On the basis of the above embodiments, in some embodiments, the determining process of each current cpu core in step S11 includes:

determining the processing types and the corresponding processing capacities of all the central processing unit cores;

screening prepared CPU cores with corresponding processing capacities larger than the preset processing capacities from other CPU cores except the service processing types in all the CPU cores;

It will be appreciated that the current CPU core in this embodiment may be based on all the CPU cores corresponding to the entire controller, and may be based on the subsequent allocation of a specific CPU core. Limitations in processing type and processing capacity are considered in this embodiment.

The CPU cores corresponding to the service processing types are screened firstly, and the corresponding screening process can be screened in a flag bit mode, or the CPU cores corresponding to the processing of the service data can be used as the setting of the CPU cores of the service processing types. In addition, the spare CPU cores with processing capacity larger than the preset processing capacity are screened from the other remaining CPU cores except the service processing type. The prepared CPU core in this embodiment may be used as an alternative for service data processing of a service thread, in consideration of a situation that the processing capability of the CPU core is higher, so as to improve the subsequent service processing efficiency.

And taking the CPU core corresponding to the service processing type and the prepared CPU core as the current CPU core so as to facilitate the subsequent balanced processing distribution in the current CPU core for distribution.

In some embodiments, after determining the corresponding target central processing unit core for service data balanced allocation according to the service balanced processing mechanism, before landing the service data on the target central processing unit core, the method further comprises:

acquiring the current throughput of each target central processing unit core;

if the current throughput is smaller than the preset throughput, acquiring the processing types and the throughput corresponding to the other target central processing unit cores except the target central processing unit core corresponding to the current throughput which is smaller than the preset throughput;

And screening out a target central processing unit core with a processing type of service processing, throughput greater than preset throughput and corresponding to the maximum throughput, and replacing the target central processing unit core with the current throughput smaller than the preset throughput so as to perform service processing.

Specifically, after determining the target CPU core, before the target CPU core is not dropped to perform service processing, the throughput of the target CPU core is checked again, so that the current dropped target CPU core can accept service data, and the throughput is ensured to reach a certain preset throughput.

And acquiring other target CPU processor cores under the condition that the current throughput is smaller than the preset throughput, wherein the other target CPU cores are CPU cores with the throughput larger than or equal to the preset throughput. And acquiring the processing types and throughput corresponding to other target CPU cores, and screening the other target CPU cores. The corresponding screening conditions are mainly that the processing type is a business processing type, the throughput is larger than the preset throughput and the throughput is maximum in other target CPU cores, and the target CPU core corresponding to the current throughput smaller than the preset throughput is replaced after screening so as to carry out business processing subsequently.

It should be noted that the filtering condition may be other conditions, such as processing capability, and the number of the replaced CPU cores may be one or more, which is not limited herein, and if the number of the replaced CPU cores is more, the target CPU core with the largest throughput may accept more than one target CPU core with the current throughput smaller than the corresponding throughput of the preset, or if the number of other target CPU cores with the largest throughput is more, balanced matching may be performed, where balanced matching may follow the above-mentioned matching process, or may use a completely new other matching processing method, which is not limited herein.

Before the service is processed by the landing, the target CPU core to be landed is checked, so that the balance of the CPU core is ensured, and the subsequent service processing efficiency is improved.

In some embodiments, after performing service processing on service data by uniformly distributing the service data to the corresponding target central processing unit core according to the service balance processing mechanism, the method further includes:

judging whether each processing capacity exceeds a preset processing capacity;

if the processing capacity exceeds the preset processing capacity, marking the target central processing unit core corresponding to the exceeding of the preset processing capacity so that the next business data is not dropped to the target central processing unit core corresponding to the exceeding of the preset processing capacity.

Specifically, after the current service data is distributed to the target CPU cores to perform service processing, for the next balanced distribution of the service data, the processing capacity corresponding to each target CPU core needs to be checked, and if the processing capacity exceeds the preset processing capacity, the target CPU cores corresponding to the exceeding preset processing capacity need to be marked, so that the next service data cannot fall into the marked target CPU cores, the processing time and the computing time of balanced distribution are saved, and the overall service processing efficiency is improved.

In some embodiments, the process of obtaining the target virtual port of the standby control node includes:

obtaining a to-be-transferred virtual port of a service corresponding to a fault control node to be transferred to a standby control node;

acquiring an initial virtual port of a link corresponding to a service processing thread formed by a host in a standby control node;

and taking the virtual port to be transferred and the initial virtual port as target virtual ports.

Specifically, the target virtual port in this embodiment may be all virtual ports of the standby control node, or may be virtual ports actually forming a link. Considering the service processing between the balanced load of the CPU core and the service data, in this embodiment, only the virtual ports in the standby control node that actually form the link are subjected to subsequent balanced matching.

The virtual port of the link actually formed in the standby control node mainly comprises an initial virtual port of the link originally corresponding to the service processing thread formed by the host in the standby control node and a virtual port to be transferred of the standby control node, wherein the service corresponding to the fault control node is transferred to the virtual port to be transferred of the standby control node, so that the time for distributing balance is shortened, and resources are saved.

Specifically, the task completion progress corresponding to each target CPU core is obtained according to the preset time, and the memory space corresponding to the service data of the completed task is cleared and recovered, so that the timing cleaning of the memory space is ensured, and the memory space is saved.

The preset time in this embodiment is not limited to a specific value, and the number of services and specific data in each target CPU core may be comprehensively considered. The timing time for cleaning and recycling is not limited, and may be set according to actual conditions.
