Detailed Description
The core of the invention is to provide a protocol configuration method, a device, equipment and a computer readable storage medium of an MCS storage system, which are used for improving the storage transmission rate of the MCS storage system.
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 obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
For ease of understanding, a system architecture to which the present invention is applicable will first be described.
The specific implementation mode provided by the embodiment of the invention is suitable for an MCS storage system, the MCS storage system mainly comprises a host and storage equipment, and a host bus adapter is arranged between the host and the storage equipment and is used for transmitting data.
At present, the following protocols are mainly used in the industry to support solid state disk data reading and writing: SCSI protocol, NVMe (Non-Volatile Memory express/NVM express) protocol, NVMoF (NVM over Fabrics) protocol. Among them, the SCSI protocol was originally used for data transmission between a host and a mechanical hard disk, but has a problem of slow transmission in the existing application. The NVMe protocol supports highly parallelized IO, thus surpassing any previous protocol, enabling the solid state disk to execute more IO threads. The NVMoF protocol takes the NVMe protocol as a foundation stone and is adapted to the Fabrics scene.
In order to improve the storage transmission rate of the MCS storage system, the embodiment of the invention installs the NVMoF protocol in the MCS storage system. However, the configuration of the existing MCS storage system does not support the NVMoF protocol, i.e., the existing NVMoF protocol cannot be directly installed in the MCS storage system. To this end, the following scheme is provided in the embodiment of the present invention to install the NVMoF protocol in the MCS storage system.
Fig. 1 is a flowchart of a protocol configuration method of an MCS storage system according to an embodiment of the present invention; fig. 2 is an IO control schematic diagram of an MCS storage system according to an embodiment of the present invention; fig. 3 is a schematic diagram of a transmission architecture of an MCS storage system according to an embodiment of the present invention; fig. 4 is a schematic system architecture diagram of an MCS storage system according to an embodiment of the present invention.
As shown in fig. 1, a protocol configuration method of an MCS storage system according to an embodiment of the present invention includes:
s101: and acquiring a source code of the MCS storage system to be configured.
S102: modifying a driver of a host bus adapter in a source code into that each physical port is a multi-core driver, adding a preset NVMoF protocol processing code in an IO interface module in the source code, and adding a preset NVMoF protocol processing module in a storage management system in the source code to obtain the configured source code.
S103: and generating an image file according to the configured source code, and deploying the image file to the MCS storage system to be configured.
The protocol configuration method of the MCS storage system provided by the embodiment of the invention can be manually executed, and can also be automatically executed by writing a script in advance.
In specific implementation, a source code of the MCS storage system to be configured is obtained, the source code of the MCS storage system to be configured is manually changed or a preset script is called for changing according to the scheme provided in step S102, the configured source code is generated into an image file, the image file is deployed to the MCS storage system to be configured, and the installation of the NVMoF protocol in the MCS storage system to be configured is completed.
In a driver of a host bus adapter (HBA card) of an existing MCS storage system, each physical port occupies a CPU core allocated to the host bus adapter, and when the number of the physical ports is greater than the number of the CPU cores, the CPU cores are cyclically multiplexed, that is, each physical port is driven by a single core. In order to increase the transmission rate, the NVMoF protocol requires a multi-core driver, and therefore, a driver of the host bus adapter needs to be modified to be the multi-core driver for each physical port. In actual use, the host bus adapter may be specifically an FC card or an RDMA card, and corresponding to different drivers, corresponding modification modes may be performed on the FC card or the RDMA card. Optionally, the driver of the host bus adapter in the source code is modified to be a multi-core driver for each physical port, specifically:
the driver is modified so that each physical port occupies all of the CPU cores allocated to the host bus adapter. Namely, each RQ/CQ + WQ/CQ group occupies one core, and all CPU cores are multiplexed among the physical ports. Wherein, RQ/CQ is Read queue completion queue, namely a Read command queue and a feedback queue thereof; WQ/CQ is the Write queue completion queue, i.e., the Write command queue and its feedback queue.
Meanwhile, in an IO interface control portion of the MCS storage system host, the source code only includes an SCSI protocol processing code, and in order to enable the MCS storage system to support the NVMoF protocol, a preset NVMoF protocol processing code needs to be added to an IO interface module in the source code, and the writing can be specifically performed with reference to an NVMoF protocol specification in advance.
As shown in fig. 2, an IO control unit of the MCS storage system includes a PLIF driver abstraction layer on an IO interface and an HL module on a host, where the HL module is configured to register an event processing and command receiving function with the PLIF module, and the PLIF module is configured to notify the HL module to process an event and receive a command. After the driver of the host bus adapter and the IO interface control part of the host are configured, development of the NVMoF protocol part needs to be carried out on an HL module of the host. After the configuration of the transmission portion between the host and the storage device is completed, the structure of the transmission portion between the host and the storage device in the MCS storage system is as shown in fig. 3, taking a host bus adapter as an example, the FC card is connected with the storage device, the FC card uploads an SCSI protocol processing code and an NVMoF protocol processing code, information transmitted to the host through the FC card is transmitted to the host through an IO interface (PLIF driving abstraction layer), different protocols can be selected in the PLIF driving abstraction layer according to different protocols for packaging processing, and then the information is input to the host through an HL module (also including the SCSI protocol processing code and the NVMoF protocol processing code).
Besides the host bus adapter between the host and the storage device and the IO interface control part of the host, the storage device also comprises a part related to communication protocol processing for improvement. For this reason, a preset NVMoF protocol processing module needs to be added to the storage management system in the source code, and finally, the configured source code is obtained. The NVMoF protocol processing module may include a creation command of the NVM subsystem and a creation command of the NVMoF controller, and is configured to associate a Namespace (Namespace) in the management storage device and a creation rule of the NVMoF controller established by setting communication between the host and the Namespace, and may be specifically written with reference to the NVMoF protocol specification in advance.
It should be noted that the above 3 actions for changing the source code may be performed simultaneously or in a non-execution order.
After generating an image file according to the configured source code and installing the image file back to the MCS storage system to be configured, the architecture of the configured MCS storage system is as shown in fig. 4, and corresponding transceiving queues (ASQ/ACQ, SQ/CQ) are set on the host for different physical interfaces; and the data is transmitted to an NVMoF controller in the storage equipment through the FC card, and enters a distributed namespace to execute read-write tasks under the management of the NVM subsystem and the control of the NVMoF controller.
After the NVMoF protocol is installed in the MCS storage system, the MCS storage system not only supports the SCSI protocol and the NVMoF protocol, but also can be compatible with the NVMe protocol.
The protocol configuration method of the MCS storage system provided by the embodiment of the invention comprises the steps of obtaining a source code of the MCS storage system to be configured, modifying a driving program of a host bus adapter in the source code into a state that each physical port is a multi-core drive, adding a preset NVMoF protocol processing code in an IO interface module in the source code, adding a preset NVMoF protocol processing module in a storage management system in the source code to obtain the configured source code, and finally generating a mirror image file according to the configured source code to be deployed to the MCS storage system to be configured, so that the MCS storage system can support storage transmission of the NVMoF protocol, support highly parallelized IO, enable a solid state disk to execute more IO threads, and improve the storage transmission rate of the MCS storage system.
On the basis of the foregoing embodiment, in order to facilitate differential processing on the original SCSI protocol and the added NVMoF protocol of the MCS storage system and avoid mutual influence, the preset NVMoF protocol processing code is added to the IO interface module in the source code in step S102 in fig. 1, which may specifically be:
and adding a target field for storing a rule for processing communication information based on the NVMoF protocol in the IO interface module.
In the concrete implementation, in order to support the coexistence of the targets of the two new protocols of the SCSI protocol and the NVMoF protocol, a new field similar to PLIF _ target _ s is added in the PLIF instance structure of the PLIF drive abstraction layer, so that the influence on the original code can be reduced, and the extension and the modification are facilitated if the content needing to be registered is different from the SCSI processing.
In the above embodiment, it is mentioned that the NVMoF protocol processing module may include a creation command of the NVM subsystem and a creation command of the NVMoF controller, and then a preset NVMoF protocol processing module is additionally set in the storage management system in the source code in step S102 in fig. 1, specifically:
an NVM subsystem creation program and an NVMoF controller creation program are added in the storage management system.
The items to be created of the NVM subsystem comprise the NVM subsystem type, a host NQN, an NVMoF protocol version number, a firmware version number, host information allowed to be accessed, the maximum namespace number, an associated namespace ID array and NVMoF controller information.
Through the NVM subsystem creation program, the NVM subsystem can be directly created when the MCS storage system with the NVMoF protocol installed is initialized, and the NVM subsystem comprises information such as NVM subsystem type, host NQN, NVMoF protocol version number, firmware version number, host information allowed to access, maximum namespace number, associated namespace ID array, NVMoF controller information and the like. The access-allowed host information specifically includes whether all hosts are allowed to access and a list of hosts allowed to access.
The name space in the storage device is associated for the NVM subsystem at the time of creation of the NVM subsystem by creating an associated name space ID array in the program for the NVM subsystem. Namespace ID (NSID) is unique within the NVM Subsystem scope, even if the above functionality is not supported, when using shared Namespace, the NSID of shared Namespace needs to be unique within the NVM Subsystem scope, i.e., all NVMoF controllers need to associate this shared Namespace using the same NSID value.
The NVMoF controller is created in the storage device through an NVMoF controller creating program, the NVMoF controller is a virtual controller, and information of the NVMoF controller is stored in the NVM subsystem and used for executing control tasks of a host access namespace process.
The NVMoF controller may select either the dynamic mode or the static mode, as described in the NVMoF specification. The dynamic mode is that when a host initiates connection, the NVMoF controller ID (controller ID) is filled in 0xFFFF, and when a target end of the storage system receives a request, an NVMoF controller is automatically created to be associated with the host. The static mode is that the target end manually creates the NVMoF controller, and the NVMoF controller ID is specified when the host initiates connection.
Optionally, the NVMoF controller is set to the dynamic mode, and the NVMoF controller creation program specifically includes:
and when a connection request of the host of the MCS storage system to be configured is received, establishing the NVMoF controller to associate a random namespace for the host of the MCS storage system to be configured.
In order to improve the security, avoid causing the target terminal to crash when a plurality of hosts frequently initiate connection, and facilitate restart recovery, so that the information of the NVMoF controller can be retained after the server disconnects the target terminal, and the NVMoF controller preferably adopts a static mode, and then the NVMoF controller creation program is specifically:
the method comprises the steps of establishing an NVMoF controller for a host to be configured with the MCS storage system in advance, and associating a fixed name space for the host to be configured with the MCS storage system.
On the basis of the detailed description of the embodiments corresponding to the protocol configuration method of the MCS storage system, the invention also discloses a protocol configuration device, equipment and a computer readable storage medium of the MCS storage system corresponding to the method.
