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 prior art, in the management process of the out-of-band box, the situations of complicated firmware development process, long project research and development period and huge project research and development cost can occur. In the application, the method and the function for realizing the chassis management firmware can be redefined, the research and development cost is reduced, the project is rapidly promoted, and the competitive power of products is improved.
The embodiment of the invention discloses a case management method, which comprises the following steps of:
step S11: and receiving a case management command sent by a service system of a preset storage array in a first protocol type through a preset front-end protocol unit, and judging the command type of the case management command.
The invention divides the management function of the out-of-band case into two parts: a front-end protocol processing unit and a core logic unit. The two units are respectively provided with an independent processor, wherein the front-end protocol processing unit is provided with an mCPU (preferably SAS expander, PCIe switch, DPU, smart NIC and the like) and is responsible for responding to an external protocol interface and receiving commands; the core logic unit is generally a dedicated embedded chip (preferably, a BMC chip) and serves as a protocol executing party to implement specific commands and policies. On different product forms, the invention completes the abstraction and solidification of main functions through two units, and only the matching protocol adaptation for different physical channels is left in the change.
In this embodiment, the preset storage array includes a management system and a service system, the service system is a party for generating and sending commands, and the management system includes the front-end protocol processing unit and a core logic unit, and is configured to process the commands sent by the service system.
When the chassis management command generated by the service system in the preset storage array is a command for the preset storage array, the service system sends the command to the management system when sending the command. When the case management command is a command for a JBOD connected with a preset storage array, the service system sends the command in a protocol type corresponding to the JBOD, and similarly, when the case management command is a command for a PCIe JBOF connected with the preset storage array, the service system sends the command in a protocol type corresponding to the PCIe JBOF; when the chassis management command is a command for an FBOF connected to a preset storage array, the service system sends the command in a protocol type corresponding to the FBOF. Specifically, the receiving, by a preset front-end protocol unit, a chassis management command sent by a service system of a preset storage array in a first protocol type includes: and receiving a chassis management command sent by a first protocol type by a first substrate management controller chip or SAS expander mCPU or PCIe switch mCPU or smart NIC mCPU in a service system of a target storage array through a first preset out-of-band chassis management information interface in a preset front-end protocol unit in a preset management system of the preset storage array.
The receiving, by the preset front-end protocol unit, a chassis management command sent by a service system of a preset storage array in a first protocol type includes: receiving a chassis management command sent by an SES protocol from an SAS expander mCPU in a service system of a target storage array through a first preset out-of-band chassis management information interface in a preset front-end protocol unit in a JBOD (just a bunch of disks) connected to the current preset storage array in advance; or, receiving a chassis Management command sent by a PCIe switch mCPU in a service system of a target storage array according to an NVMe-MI (Management Interface) Protocol or an MRPC (Media Resource Control Protocol) Protocol through a second preset out-of-band chassis Management information Interface in a preset front-end Protocol unit in a PCIe JBOF that is connected to the current preset storage array in advance; or, receiving a chassis management command sent by a smartNIC or DPU mCPU in a service system of a target storage array in a first protocol type through a third preset out-of-band chassis management information interface in a preset front-end protocol unit in the FBOF which is connected to the preset storage array in advance.
That is to say, in this embodiment, the default storage array may use, but is not limited to, BMC/SAS expander mCPU/pci switch mCPU/smart NIC mCPU for chassis management; due to physical networking limitation, JBOD can only use SAS expander mCPU as an uplink communication channel, and the chassis management function can only use an SES protocol through the SAS expander; PCIe JBOF can only use PCIe Switch mCPU as an uplink communication channel due to the limitation of physical networking, and the chassis management function can only use the NVMe-MI/MRPC protocol through the PCIe Switch mCPU; due to the limitation of physical networking, the FBoF can only use smartNIC/DPU mCPU as an uplink communication channel, and the chassis management function can only pass through smartNIC/DPU mCPU. In addition, in this embodiment, the first predetermined out-of-band enclosure management information interface, the second predetermined out-of-band enclosure management information interface, and the third predetermined out-of-band enclosure management information interface are all in the predetermined front-end protocol unit, and are completed by a dedicated mCPU channel and a dedicated protocol, and are responsible for functional interaction between other systems of the storage device and the external storage cross-system interface.
In the application, the uplink channel managed by the out-of-band case is limited by physical networking and can not be changed randomly, the protocol is influenced by the industry mainstream protocol, and the standard/mainstream protocol is proposed in consideration of the adaptation workload and the industry compatibility. Therefore, the scheme diversifies the selection of the front-end uplink channel protocol and does not limit the uplink channel. However, in the back-end default core logic unit proposed in the present invention, the core logic of the chassis management is not strongly coupled to the upstream protocol provider, but is solidified by using a dedicated embedded chip (including but not limited to BMC) firmware (hereinafter referred to as out-of-band chassis management core logic unit).
In this embodiment, the chassis management command may be a plurality of commands such as sensor information acquisition, fault detection, fault report, information acquisition protocol support, chassis heat dissipation policy, firmware upgrade, hard disk information out-of-band management, interface card information out-of-band management, lighting, configuration, Log (Log) collection, and the like, which is not limited herein.
Step S12: and if the command type of the case management command is a first type, processing the case management command by using a first processor in the preset front-end protocol unit.
In this embodiment, the service system may directly send the chassis management command to the preset front-end protocol unit, and the front-end protocol unit may determine, based on a preset determination rule, whether the unit may independently execute the chassis management command after receiving the chassis management command, and if the unit may independently execute the chassis management command, the unit may determine the chassis management command as the first type, and may directly execute the chassis management command without forwarding the chassis management command to the preset core logic unit.
Step S13: if the command type of the chassis management command is a second type, the preset front-end protocol unit is used for forwarding the chassis management command to a preset core logic unit, so that the preset core logic unit converts the received chassis management command into the second protocol type by using a second processor for processing.
In this embodiment, if the front-end protocol unit receives the chassis management command, it determines whether the unit can execute the chassis management command alone based on a preset determination rule, and if the unit cannot execute alone, the front-end protocol unit needs to forward the command to the preset core logic unit for execution according to a downlink protocol requirement. The preset core logic unit carries out protocol conversion in the subsequent process, and converts the protocol conversion into a format which can be processed by the unit, thereby completing the management functions of the chassis such as out-of-band information acquisition, configuration, upgrading, Log collection, lighting and the like. In a specific embodiment, the format may be converted into a protocol format including, but not limited to, IPMI (Intelligent Platform Management Interface), SES, MRPC, NVME-MI, and the like, which is not limited herein.
It should be noted that the first type of command in this embodiment is relatively small in the actual implementation process, and in most cases, the chassis management command received by the front-end protocol unit cannot be executed alone. That is, in most cases, the preset frontend protocol unit will forward the chassis management command to the preset core logic unit for execution. In the forwarding process, protocol conversion processing is not carried out on the case management command in principle, and protocol conversion is reserved for a downstream core logic unit.
In the method, a case management command sent by a business system of a preset storage array in a first protocol type is received through a preset front-end protocol unit, and the command type of the case management command is judged; if the command type of the case management command is a first type, processing the case management command by using a first processor in the preset front-end protocol unit; if the command type of the chassis management command is a second type, the preset front-end protocol unit is used for forwarding the chassis management command to a preset core logic unit, so that the preset core logic unit converts the received chassis management command into the second protocol type by using a second processor for processing. Therefore, the management function body logic of the out-of-band case is abstracted and divided into the preset front-end protocol unit and the preset core logic unit, wherein the preset front-end protocol unit is used as a front end and uses mCPU, the preset core logic unit is used as a rear end and uses a special embedded chip, and the double CPUs finish the management work of the out-of-band case, so that the stability of the management function body logic of the out-of-band case is realized. And the preset front-end protocol unit is responsible for external protocol service, minimizes the working content, transfers the protocol conversion work to the preset core logic unit for protocol conversion, and the whole case management process does not need to change along with the change of the case form, thereby being convenient for quality stability and saving development manpower.
Fig. 2 is a flowchart of a specific enclosure management method according to an embodiment of the present disclosure. Referring to fig. 2, the method includes:
step S21: and receiving a case management command sent by a service system of a preset storage array in a first protocol type through a preset front-end protocol unit, and judging the command type of the case management command.
For a more specific processing procedure of step S21, reference may be made to corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.
Step S22: and if the command type of the case management command is a first type, processing the case management command by using a first processor in the preset front-end protocol unit.
For a more specific processing procedure of step S22, reference may be made to corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.
Step S23: if the command type of the chassis management command is a second type, the chassis management command is forwarded to a preset core logic unit through a preset first channel by using the preset front-end protocol unit, so that the preset core logic unit converts the received chassis management command into the second protocol type by using a second processor for processing.
In this embodiment, the forwarding the chassis management command to a preset core logic unit by using the preset front-end protocol unit so that the preset core logic unit converts the received chassis management command into a second protocol type by using a second processor for processing may include: and forwarding the case management command to a preset embedded chip by using the preset front-end protocol unit so that the preset embedded chip converts the received case management command into a second protocol type by using a second processor in the chip for processing. In this embodiment, the forwarding the chassis management command to a preset embedded chip by using the preset front-end protocol unit so that the preset embedded chip converts the received chassis management command into a second protocol type by using a second processor in the chip to process the received chassis management command may include: and forwarding the case management command to a second baseboard management controller chip by using the preset front-end protocol unit, so that the second baseboard management controller chip converts the received case management command into a second protocol type by using a second processor in the chip for processing.
It is understood that, in this embodiment, the preset front-end protocol unit is a dedicated embedded chip, preferably a BMC chip, but includes but is not limited to the BMC chip.
Step S24: and determining target information corresponding to the case management command.
In this embodiment, after the preset core logic unit receives the chassis management command and performs protocol conversion on the command, the corresponding execution of the chassis management command may be performed, and in some specific embodiments, a small amount of execution needs to be carried by the preset front-end protocol processing unit, that is, the preset core logic unit may request the preset front-end protocol unit for target information, so as to execute the chassis management command by using the target information. At this time, the preset core logic unit, i.e., the dedicated embedded chip firmware, may serve as an initiator of the information acquisition protocol, and the preset front-end protocol processing unit may serve as a responder of the protocol.
Step S25: and sending a target information acquisition request to the preset front-end protocol unit through a preset second channel, and receiving target information returned by the preset front-end protocol unit aiming at the target information acquisition request through the preset second channel.
It should be noted that, in this embodiment, the first channel of the preset front-end protocol unit for forwarding the chassis management command and the interaction channel of the preset core logic unit for processing the chassis management command are not the same channel, that is, the first channel is used when the preset front-end protocol unit forwards the command, and the second channel is used when the subsequent preset core logic unit processes the command and is no longer shared with the first channel for forwarding the command.
Step S26: and processing the case management command based on the target information.
In this embodiment, after the preset core logic unit acquires the target information from the preset front-end protocol unit, the preset core logic unit may continue to execute the chassis management command by using the target information.
In this embodiment, a preset front-end protocol unit receives a chassis management command sent by a service system of a preset storage array in a first protocol type, and determines a command type of the chassis management command; if the command type of the case management command is a first type, processing the case management command by using a first processor in the preset front-end protocol unit; if the command type of the chassis management command is a second type, the chassis management command is forwarded to a preset core logic unit through a preset first channel by using the preset front-end protocol unit, so that the received chassis management command is converted into the second protocol type by using a second processor by the preset core logic unit for processing; determining target information corresponding to the case management command; and sending a target information acquisition request to the preset front-end protocol unit through a preset second channel, and receiving target information returned by the preset front-end protocol unit aiming at the target information acquisition request through the preset second channel. (ii) a And processing the case management command based on the target information. Therefore, the logic of the management function body of the out-of-band case is abstractly solidified to an independent embedded chip, and the interaction process of the embedded chip and the preset front-end protocol unit of the front end and the forwarding process of the preset front-end protocol unit to the command do not use the same channel, so that the stability of the logic of the management function body of the out-of-band case is realized, the change along with the change of the form of the case is not needed, and the quality is stable, and the development labor is saved. When the SAS expander, the PCIe switch, the DPU, the smart NIC and other chips are used for replacement, only an external protocol processing part needs to be transplanted, the replacement speed is high, the cost is low, the stability of a supply chain is facilitated, the development cost of the whole project is low, the period is short, the SAS expander, the PCIe switch, the DPU, the smart NIC and other chips can be quickly pushed to the market, and the product competitiveness is improved.
