Detailed Description
The core of the application is to provide a storage test method, which can conveniently, effectively and low-cost carry out storage test under the network environment of a public network so as to optimize the storage performance of a storage server and improve the storage applicability; at the other core of the present application, a storage test system and a computer-readable storage medium are provided, which have the above technical effects.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a memory test method according to an embodiment of the present disclosure; referring to fig. 1, the storage test method includes:
s101: a network congestion simulation server receives a data packet sent by a client server;
s102: the network congestion simulation server transmits the data packet to the storage server in a delayed manner by using a preset network congestion simulation tool according to a preset network congestion simulation strategy, and/or transmits the data packet to the storage server after exception processing is carried out on the data packet;
s103: and the storage server receives the data packet and tests the performance of the storage server by using a preset test tool.
Specifically, the network congestion simulation server is arranged between a client and a storage server, the network congestion simulation server is respectively connected with the client and the storage server through network cables, and a network congestion simulation tool, namely the preset network congestion simulation tool, is arranged on the network congestion simulation server, so that the preset network congestion tool is used for simulating network congestion in a public network according to a preset network congestion simulation strategy to construct a weak network environment. Specifically, the client server normally sends data packets through the public network, the network congestion simulation service delays and sends the data packets to the storage server after receiving the data packets sent by the client, and/or the network congestion simulation server first performs exception handling on the data packets after receiving the data packets sent by the client, and then sends the data packets to the storage server, for example, the network congestion simulation server randomly discards part of the data packets and then sends the rest of the data packets to the storage server. Further, after receiving the data packets which are sent in a delayed manner and/or have abnormal packet loss and the like, the storage server tests and evaluates the performance of the storage server in the weak network environment by using a preset testing tool.
It can be understood that, on the basis of the existing server, the network congestion simulation tool is installed and the network congestion simulation server can be obtained by performing relevant configuration correspondingly without setting a special server, so that the test cost is greatly reduced. Therefore, under the condition of carrying out relevant configuration on the storage server and the client server, the network congestion environment can be simulated by using the network congestion simulation server, the storage test is realized by the preset test tool on the storage server, and the aim of conveniently and effectively carrying out the storage test under the network environment of a public network is fulfilled.
The method comprises the steps that a storage server is configured, wherein the step of configuring the storage server comprises the steps of adding a server initial name and creating a host on a storage management interface; and creating a raid and a volume in the storage server, and mapping the volume to the host. Configuring the client server includes the client server scanning for additional storage volumes.
In addition, the specific type of the preset network congestion simulation tool and the specific type of the test tool are not limited uniquely, and the difference setting can be performed according to the actual situation under the condition that the network congestion can be simulated and the performance of the storage server can be tested.
In a specific embodiment, the preset network congestion simulation tool may be a Traffic Control tool. In a specific embodiment, the predetermined testing tool may be a vddnch testing tool. For the Traffic Control tool and the vbreach testing tool, details are not repeated herein, and reference may be made to the introduction of the existing document to the Traffic Control tool and the vbreach testing tool.
Furthermore, the network congestion content simulated by the network congestion simulation server, namely the specific way of sending the data packet in a delayed manner and the specific content of performing exception handling on the data packet, is not limited in the present application, and naturally, the more possible network congestion conditions simulated by the network congestion simulation server, the more the accuracy and reliability of the performance test result of the storage server can be ensured.
In a specific embodiment, the network congestion simulation server may delay sending the data packet to the storage server by the network congestion simulation server, where the network congestion simulation server delays the data packet by a preset time and sends the data packet to the storage server, or the network congestion simulation server sends the data packet to the storage server within a first preset delay time, or the network congestion simulation server delays the data packet by a first preset time and sends the data packet to the storage server, and sends the data packet of a second preset proportion to the storage server within a second preset delay time.
Specifically, this embodiment provides several specific ways of delaying sending a data packet, including:
and the network congestion simulation server delays the data packet for a preset time and then sends the data packet to the storage server. In this way, the delay time is fixed, and all the data packets are sent to the storage server after being delayed for the preset time. For example, the network congestion simulation server sends each data packet to the storage server with a delay of 200ms, and the corresponding program script may be as follows:
#tc qdisc add dev eth0 root netem delay 200ms
and the network congestion simulation server sends the data packet to the storage server within a first preset delay time range. In this way, the delay duration fluctuates, and the delay transmission duration of each data packet is within the first preset delay duration range. For example, the network congestion simulation server sends the data packets to the storage server within a delay time range of 100ms ± 20ms, the delay sending time of each data packet is any value between 80 and 120ms, and the corresponding program script may be as follows:
#tc qdisc add dev eth0 root netem delay 100ms 20ms
the network congestion simulation server delays the data packets with the first preset proportion for a first preset time and then sends the data packets with the first preset proportion to the storage server, and the data packets with the second preset proportion are sent to the storage server within a second preset delay time range. In this way, the delay durations of the data packets of the first preset proportion are fixed and are all the first preset durations, the delay durations of the data packets of the second preset proportion fluctuate, and the delay durations of the data packets of the second preset proportion are all within the range of the second preset delay durations. For example, if the second preset proportion is 30%, the first preset proportion is 70%, the network congestion simulation server transmits 70% of the data packets to the storage server with a delay of 100ms, and transmits 30% of the data packets to the storage server within a delay duration range of 100ms ± 10ms, and the corresponding program scripts may be as follows:
#tc qdisc add dev eth0 root netem delay 100ms 10ms 30％
in addition, in a specific embodiment, the performing of the exception handling on the data packet by the network congestion simulation server may include that the network congestion simulation server randomly discards a data packet with a third preset proportion, or the network congestion simulation server randomly generates a repeated data packet with a fourth preset proportion, or the network congestion simulation server damages a data packet with a fifth preset proportion, or the network congestion simulation server immediately sends a data packet with the sixth preset proportion and sends the remaining data packets after a preset duration.
Specifically, this embodiment provides specific contents of several types of data packet exception handling, including:
and the network congestion simulation server randomly discards the data packets with the third preset proportion, namely after receiving the data packets sent by the client, the network congestion simulation server randomly discards part of the data packets and sends the rest of the data packets to the storage server. For example, if the network congestion simulation server randomly discards 2% of the data packets, the corresponding program script may be as follows:
#tc qdisc add dev eth0 root netem loss 2％
the network congestion simulation server randomly generates repeated data packets with a fourth preset proportion, namely after receiving the data packets sent by the client, the network congestion simulation server randomly generates data packets repeated with part of the data packets, and then sends all the data packets including the repeated data packets to the storage server. For example, the network congestion simulation server generates 2% duplicate packets, and the corresponding program script may be as follows:
#tc qdisc add dev eth0 root netem duplicate 2％
and the network congestion simulation server damages the data packets with the fifth preset proportion, namely after receiving the data packets sent by the client, the network congestion simulation server randomly calculates out part of the data packets, and then sends the normal and damaged data packets to the storage server. For example, if the network congestion simulation server randomly generates 0.2% damaged packets, the corresponding program script may be as follows:
#tc qdisc add dev eth0 root netem corrupt 0.2％
and the network congestion simulation server immediately sends the sixth data packet with a preset proportion and sends the rest data packets after a preset time length, namely the network congestion simulation server carries out disorder operation on the data packets, and after receiving the data packets, the network congestion simulation server immediately sends part of the data packets to the storage server and delays and sends the part of the data packets to the storage server. For example, if the network congestion simulation server sends 25% of the data packets to the storage server immediately and the other data packets to the storage server with a delay of 10ms, the corresponding program script may be as follows:
#tc qdisc change dev eth0 root netem delay 10ms reorder 25％50％
wherein 50% means that the packet has a correlation of 50%.
