In order to solve the above-mentioned problem, in this embodiment, a method for accessing a server is provided, and fig. 2 is a flowchart of a method for accessing a server according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:
step S202, a download instruction is sent to an intelligent network card server and a cloud disk server, wherein the download instruction is used for indicating the intelligent network card server and the cloud disk server to download and install software packages;
it should be noted that, the software package uses a storage high-performance development suite (Storage Performance Development Kit, abbreviated as SPDK), and the SPDK provides a feature of zero copy and high concurrency for directly accessing a Solid State Disk (SSD) from a user State based on a Non-Volatile Memory (NVME) driver.
IT should be noted that, the cloud disk server is a simple, efficient and elastically scalable computing service with processing capability, helps users to quickly construct more stable and safe applications, improves operation and maintenance efficiency, reduces IT cost, has high stability and expansibility, provides a large-capacity cloud storage space, can upload files to the cloud disk server, can serve at any time through a network, can conveniently carry out data backup and recovery through the cloud disk server, and supports multi-platform use and sharing collaboration.
Step S204, under the condition that the intelligent network card server and the cloud disk server both download the installation software package, starting a device driver in the installation software package so as to configure a first network port for the intelligent network card server through a programmable logic device; starting a user state process in the installation software package to transmit configuration data of the cloud disk server to a second network port of the cloud disk server;
it should be noted that, the software package downloaded in the intelligent network card server is also SPDK. In addition, after the first portal and the second portal establish a connection, a request may be sent to one of the servers for requesting the server to perform a specific operation, including, but not limited to, acquiring data, storing data, etc.; meanwhile, another server may also receive a response returned by the server, which may include a variety of information. Data may also be input or output to the server via a connection, such as uploading a file to the server or downloading a file from the server.
It should be noted that, the programmable logic device (Field-Programmable Gate Array, abbreviated as FPGA) is composed of a large number of logic gates, memory cells and programmable internal connection networks, and the FPGA has a high parallel processing capability, can perform multiple tasks at the same time, and improves the performance of the system.
The packet processing workload can be transferred from the CPU to the FPGA-based intelligent network card by using the intelligent network card. By offloading the network processing workload and tasks of the server CPU, the intelligent network card improves server performance of the cloud and private data centers. Under the push of the continuous increase of network flow and computational complexity of a data center, an intelligent network card is adopted to provide a processing architecture, calculation is provided for some workloads through the intelligent network card, and the workloads are unloaded from a general computing kernel, so that the efficiency of the overall solution is improved.
It should be noted that the intelligent network card not only can realize the connection function of the network card, but also can realize the network flow processing usually executed by the CPU. The intelligent network card can perform encryption/decryption, firewall, TCP/IP, and HTTP processing.
It should be noted that, after the server establishes a connection, the connection may be used for authentication to ensure security and reliability of data. Meanwhile, as the server establishes connection, the method is more convenient and faster in the process of processing error problems and monitoring state performance.
Step S206, when the configuration data has been successfully transmitted to the second network port, establishing a connection between the first network port and the second network port according to a transmission protocol, so that the intelligent network card server accesses the cloud disk server through the connection.
The transmission protocol is a transmission control protocol (Transmission Control Protocol, abbreviated as TCP), and works based on an internet control protocol (Internet Protocol, abbreviated as IP), and TCP ensures reliable transmission of data by establishing a connection, dividing and reassembling data, acknowledging receipt and retransmission of lost data packets, and other mechanisms.
Through the steps S202-S206, under the condition that the cloud disk server and the intelligent network card server successfully install the software package, a device driver in the installation software package is started, and a first network port is configured for the intelligent network card server through a programmable logic device; starting a user state process in the installation software package, and transmitting configuration data of the cloud disk server to a second network port of the cloud disk server; and establishing connection between the first network port and the second network port according to a transmission protocol, so that the intelligent network card server accesses the cloud disk server through the connection. The problem that the intelligent network card server cannot access the cloud disk server in the prior art is solved, and the technical effect that the cloud disk system server is started and accessed through the intelligent network card server is achieved.
In an exemplary embodiment, before establishing the connection between the first portal and the second portal according to the transmission protocol, the method further includes the following steps S11-S14:
step S11: sending an installation instruction to a cloud disk server system, wherein the installation instruction is used for indicating the cloud disk server system to install a cloud operating system compression packet, and the cloud disk server system is positioned in the cloud disk server;
it should be noted that, before the connection of the servers is established, it needs to be ensured that the servers and the network have already established a connection, and on this basis, the connection between the servers can be achieved, after the network connection is established, it needs to be confirmed that the same communication protocol is adopted between the two servers, and common protocols include TCP, HTTP and the like, and in addition, other configurations may also need to be performed, such as proxy setting, domain name resolution and the like, through which the user state process can be invoked.
Step S12: under the condition that the cloud disk server system is provided with a cloud operating system compression packet, a first modification instruction is sent to an intelligent network card system to instruct the intelligent network card system to modify a first configuration file, and a second modification instruction is sent to the cloud disk server system to instruct the intelligent network card system to modify a second configuration file, wherein the intelligent network card system is positioned in the intelligent network card server;
It should be noted that the modification to the configuration file includes, but is not limited to, the size of the large page memory, and the number of the large page memory. And the configuration files are grub configuration files of the cloud disk server system and the intelligent network card system.
After the large page memory is modified, the memory management overhead can be reduced, and the size and maintenance overhead of the page table can be reduced, so that the access time is reduced, the throughput and response time of the system are improved, the problem of memory fragmentation is avoided, and the waste of the memory is reduced. The traditional small page mechanism may cause memory fragmentation, thereby reducing the memory utilization rate of the system, and for some application programs which need a large amount of memory, such as a database, a virtual machine and the like, the large page can reduce the cost of memory access, and improve the access speed of data, so as to accelerate the running speed of the application programs.
Step S13: sending a restarting instruction to the cloud disk server system and the intelligent network card system under the condition that the first configuration file is modified by the intelligent network card system and the second configuration file is modified by the cloud disk server system so as to indicate that the cloud disk server system and the intelligent network card system are both restarted;
It should be noted that, because the number of pages and the size of the large page memory of the configuration files of the intelligent network card system and the cloud disk server system are modified, the modified configuration files can be validated only after restarting the system.
Step S14: the method comprises the steps of validating a modified first configuration file in the restarted intelligent network card system and validating a modified second configuration file in the restarted cloud disk server system.
In an exemplary embodiment, the above step S204 may be implemented by the following steps S21-S22:
step S21: determining a plurality of user state processes corresponding to the cloud disk server; determining a user state process for transmitting the configuration data from the plurality of user state processes;
it should be noted that, after the software package is installed, a user state process will appear, it needs to determine whether there is only one latest user state process, if there is another user state process, all previous user state processes need to be removed, and only the latest user state process is reserved, so as to ensure that after the user state process is started, the environment configuration can be performed.
Step S22: and starting the user state process of the configuration data to transmit the configuration data of the cloud disk server to a second network port of the cloud disk server.
In an exemplary embodiment, the above step S206 may be implemented by the following steps S31-S32:
step S31: the configuration data comprises: determining whether a conflict exists between the first network parameter and the second network parameter under the condition of the first network parameter of the first network port and the second network parameter of the second network port;
step S32: and under the condition that no conflict exists between the first network parameter and the second network parameter, establishing connection between the first network port and the second network port through the transmission protocol.
It should be noted that, the determination that the network parameters between the two network ports do not have a conflict is to avoid that a subnet mask or a gateway and the like have a conflict, avoid that data cannot be transmitted and forwarded correctly due to the conflict of the network parameters, ensure that communication and data exchange can be performed normally between network devices, and thus improve stability and reliability of the network.
In an exemplary embodiment, after establishing the connection between the first portal and the second portal according to the transmission protocol, the method further includes the following steps S41-S42:
step S41: executing a network port test command in the configuration data through the second network port, wherein the network port test command is used for establishing connection with a network address of the first network port;
Step S42: and under the condition that a response instruction of the first network port to the network port test command is received within a preset time period, the first network port and the second network port are confirmed to be successfully connected.
In an exemplary embodiment, after establishing the connection between the first network port and the second network port according to a transmission protocol, so that the intelligent network card server accesses the cloud disk server through the connection, the method further includes the following steps S51-S52:
step S51: sending a control request to the cloud disk server through the connection, wherein the control request is used for requesting to control target equipment corresponding to the cloud disk server;
step S52: and under the condition that the control request passes verification, sending a control instruction to the target equipment through the connection and the cloud disk server so as to instruct the target equipment to execute an operation corresponding to the control instruction.

It will be apparent that the embodiments described above are merely some, but not all, embodiments of the application. For better understanding of the above method, the following description will explain the above process with reference to the examples, but is not intended to limit the technical solution of the embodiments of the present application, specifically:
the application provides a cloud disk system building method based on SPDK and HugePages technology, which can truly simulate the cloud disk system of an Internet manufacturer and truly realize cloud disk starting and entering the cloud disk system.
As an alternative example, fig. 3 illustrates a cloud disk test topology of a server access method, in which the relationship between the server access method and the cloud disk configuration is illustrated, and further illustrates the connection manner and the data flow between the components. In addition, in order to better understand the connection relationship between the network interface card and the components, the function of the network interface card is analyzed, fig. 4 illustrates a structure diagram of the network interface card based on the programmable logic device and the intelligent network card, and the positions and connection modes of each component in the network interface card can be intuitively known through the schematic diagram. Meanwhile, in order to demonstrate the relationship and interaction between the components of the cloud operating system in a visual manner, fig. 5 illustrates a control structure diagram of the cloud operating system.
The SPDK technology utilized in the present application provides a set of tools and libraries for writing high performance, scalable user-mode storage applications. The following key technologies are provided in SPDK for implementing writing applications:
(1) All necessary drivers are moved to the user space, so that system call can be avoided, and zero copy access of the application program is enabled;
(2) In the completion of the project, the mode of polling hardware is used, and no interrupt is used;
(3) In processing the input-output path, to avoid the lock mechanism, a message passing mechanism is used;
(4) A complete block stack is provided as a user space library, performing many of the same operations as the block stack in the operating system. The method comprises the steps of unifying interfaces among different storage devices, queuing to handle situations such as insufficient memory or suspended input or output, logical volume management and the like;
the SPDK provides servers built based on these components that can provide disks through a network or other processes. The CPU efficiency of these servers can be as high as an order of magnitude compared to other implementations. These objectives may be used as examples of how to achieve high performance storage objectives or as a basis for production deployment.
In addition, the HugePages technology used in the present application aims to use larger pages (memory page size) to adapt to larger and larger system memory, so that the operating system can support the large capacity function of the modern hardware architecture, and has the following advantages:
(1) If the memory is not exchangeable, the page in/out is avoided or reduced when the memory usage is higher;
(2) The pressure of the hardware cache (Translation Lookaside Buffer, called TLB for short) is relieved, and the physical memory range pointed by each Page is enlarged, so that a larger memory space can be managed by fewer Page table entries.
(3) The overhead of page table space occupation and page table inquiry is reduced;
(4) And the overall performance of memory access is improved.
By adopting the two technologies, the application changes the design of the cloud disk server and the intelligent network card server, and is specific:
