With the continuous development of computer technology and the explosive growth of various types of information, disks capable of storing a large amount of data have gradually become an indispensable part of people's lives. SSD (Solid State Disk or Solid State Drive) is currently the mainstream disk. Compared with a traditional disk, SSD adopts flash memory as a storage medium, thus it can read and write faster, and SSD has better shock resistance and impact resistance because it does not include any mechanical parts. Moreover, the SSD has the advantages of lower power consumption, less noise, and lighter weight, which makes the SSD more popular.

In order to ensure the online upgrading between the host and the SSD without interrupting service, a currently more mainstream method is to use transitional firmware to complete the firmware upgrade, and this upgrade method leads to a higher difficulty and complexity in implementation, thus reducing the reliability of the upgrade.

To make the objects, features, and advantages of the present disclosure clearer and easier to be understood, the present disclosure will be illustrated in details in conjunction with the accompanying drawings and specific embodiments.
In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present disclosure, some of the technical features involved in the embodiments of the present disclosure are explained and described below.
SSD (solid state disk or solid state drive) is the current mainstream hard disk, which has advantages described below compared with a traditional hard disk.
Fast read and write speed: by using flash memory as the storage medium, the read speed is faster compared to a mechanical hard disk.
Shock resistance and impact resistance: traditional hard disks are magnetic hard disks with data stored in magnetic disk sectors, while SSDs are made from flash memory chips, that is, the SSDs do not have mechanical parts; accordingly, the normal use thereof is not affected even when SSDs move at a high speed and even when they are overturned and tilted, and the possibility of data loss can be minimized in the event of collision and vibration; SSDs have an absolute advantage over the traditional hard disk in terms of shock resistance and impact resistance.
Low power consumption: the power consumption of SSDs is lower than that of traditional hard disks, and due to the use of flash memory chips without mechanical components, SSDs also have the characteristics of less heat generation and fast heat dissipation.
Noiseless: SSDs do not have mechanical motors and fans, thus a noise level thereof during operation is 0 dB, and flash-based SSDs typically have low energy consumption and heat generation in an operation state.
Large range of operating temperature: typical hard disk drives can only operate in a range of 5˜55° C., while most SSD can operate in a range of −10˜70° C.
Light weight: SSDs are smaller and lighter than a mechanical hard disk of the same capacity, and 20-30 grams lighter than a conventional 1.8 inch hard disk.
Firmware (FW) refers to programs written in EPROM (Erasable Programmable Read Only Memory) or EEPROM (Electrically Erasable Programmable Read-Only Memory), and also refers to the device “driver” stored in the device. The operating system relies on firmware (for example, firmware in the SSD) to drive a specific machine to operate according to a standard device driver. In order to make the SSD have comprehensive functions, the firmware needs to be upgraded.
Firmware version information mainly refers to a version number and version code of firmware, and is used for identifying the firmware version.
As an example, SSDs are usually connected with external devices capable of communicating, such as a host. Therefore, during the process of service interaction, the host requires the SSDs to upgrade firmware from time to time, which involves a switching between an old version of firmware and a new version of firmware. In order to ensure the online upgrading without interrupting service between the host and the SSD, a currently more mainstream method is to use transitional firmware to complete the firmware upgrade. In the upgrade process, it is required to ensure that hardware units inside the solid state disk still operate normally, and the internal message network is also required to be kept in a normal operation state. Therefore, this upgrade method leads to a higher difficulty and complexity in implementation, thus reducing the reliability of the upgrade.
In view of the above, one of the core creative points of the embodiments of the present disclosure is providing an online upgrading method for a solid state disk. The solid state disk includes at least an internal process interaction unit, as well as a CPU processing unit, a serial communication unit, a storage unit, a memory processing unit and a control peripheral unit that are respectively in communication connection with the internal process interaction unit. The solid state disk is in communication connection with a host via a serial communication unit. Firstly, in response to receiving a firmware upgrade instruction sent from the host, an interaction mode of the serial communication unit is set as a pause mode so as to ensure that no instruction sent from the host is received before the upgrade is completed. Next, the CPU processing unit is triggered to perform power-down processing, various units in the solid state disk are controlled to be switched to a standby state so as to ensure data consistency before and after the upgrade, and to ensure that no internal information interaction exists inside the solid state disk before the upgrade is completed. Next, a system reset operation is triggered for the solid state disk on the basis of the standby state, and firmware upgrade is performed on the solid state disk according to the firmware upgrade instruction. Finally, in response to the firmware upgrade being completed, initialization processing is performed on various units in the solid state disk, and the pause mode of the serial communication unit is canceled. Through the initialization processing of various units, the solid state disk is in a re-initialized state, it is not necessary to maintain the state before the upgrade, and it is not necessary to resume the information interaction before the upgrade. Therefore, the online upgrading can be completed in seconds without interrupting services, which greatly simplifies boundary processing of the new version of firmware, and improves the simplicity of firmware switching, upgrade efficiency and upgrade reliability.
With reference to
For the solid state disk side, the solid state disk may at least include an internal process interaction unit, as well as a CPU processing unit, a serial communication unit, a storage unit, a memory processing unit and a control peripheral unit that are respectively in communication connection with the internal process interaction unit. The solid state disk may be in communication connection with a host via a port system of the serial communication unit, and the serial communication unit may also include an application subsystem, so that the solid state disk may respond when an application is running. Furthermore, the other units in the solid state disk can be controlled by the CPU processing unit (such as a control flow direction indicated by a dotted line in
In particular, the serial communication unit may be a PCIe (Peripheral Component Interconnect Express), and the internal process interaction unit may include an IPC internal information interaction network.
As a hardware unit interface interacting with a host, the PCIe may support the setting of a pause mode and a normal mode. The pause mode and the normal mode are two modes supported by the PCIe, and may be controlled and set via firmware. Under normal operating conditions, the interaction mode of the PCIe is the normal mode, and all the instructions from the host can be received in this case. When firmware upgrade is required, the interaction mode of the PCIe may be set as the pause mode after an upgrade instruction is received. Before the firmware upgrading is completed, no more instructions are obtained from the host, and only instructions inside the solid state disk are processed. When the firmware upgrading is completed, that is, when the firmware is switched from an old version to a new version, the interaction mode of the PCIe may be reset as the normal mode, such that the solid state disk can continue to receive and process instructions from the host.
For the IPC internal information interaction network, information is transferred and maintained via a Head (starting queue recording variable) and a Tail (ending queue recording variable) of a message cache queue, among them, the Head is used for recording a first position of the queue, and the Tail is used for recording a next position of a last position of the queue. For example, when unit A and unit B perform information interaction via the IPC internal information interaction network, the two together maintain the Head and the Tail of a message cache queue (a ring queue). When unit A sends information to unit B, unit A needs to maintain Tail information about the message cache queue, and the count of the Tail is incremented. When unit B processes information sent from unit A, the Head of the same message cache queue is maintained, namely, when information in the message cache queue is taken out, the count of the Head is incremented, that is to say, when unit A sends information to unit B, unit A maintains the Tail, and unit B maintains the Head, thereby achieving joint maintenance of the message cache queue by them.
It should be noted that the embodiments of the present disclosure include but are not limited to the above-mentioned examples, and it can be understood that those skilled in the art would have been able to make arrangements according to actual needs under the guidance of the idea of the embodiments of the present disclosure, which is not limited in the present disclosure.
In the embodiment of the present disclosure, an internal structural framework of a solid state disk is provided. The solid state disk includes at least an internal process interaction unit, as well as a CPU processing unit, a serial communication unit, a storage unit, a memory processing unit and a control peripheral unit that are respectively in communication connection with the internal process interaction unit. The solid state disk is in communication connection with a host via the serial communication unit. Firstly, in response to receiving a firmware upgrade instruction sent from the host, the interaction mode of the serial communication unit is set as the pause mode so as to ensure that no instruction sent from the host is received before the upgrade is completed. Then, the CPU processing unit is triggered to perform power-down processing, all units in the solid state disk are controlled to be switched to a standby state so as to ensure data consistency before and after the upgrade, and to ensure that there is no internal information interaction inside the solid state disk before the upgrade is completed. Then, a system reset operation is triggered for the solid state disk on the basis of the standby state, and firmware upgrade is performed on the solid state disk according to the firmware upgrade instruction. Finally, in response to the completion of the firmware upgrade, initialization processing is performed on each unit in the solid state disk, and the pause mode of the serial communication unit is canceled. Through the initialization processing of each unit, the solid state disk is in a re-initialized state, it is not necessary to maintain the state before the upgrade, and not necessary to resume the information interaction before the upgrade, so that the online upgrading can be completed in seconds without interrupting services. Therefore, boundary processing of the new version of firmware is greatly simplified, and the simplicity of firmware switching, upgrade efficiency and upgrade reliability are improved.
With reference to
In step 201, an interaction mode of the serial communication unit is set as a pause mode in response to receiving a firmware upgrade instruction sent from the host.
In particular, in response to receiving the firmware upgrade instruction sent from the host, the interaction mode of the serial communication unit is set from the normal mode to the pause mode, which may be achieved by means of firmware, namely, by means of writing a hardware register. These two modes are set in the serial communication unit. After the interaction mode of the serial communication unit is set as the pause mode, the serial communication unit will not initiate an action of acquiring instructions from the host, and the solid state disk will not receive instructions from the host before the upgrade is completed.
In some embodiments of the present disclosure, the step, in which the interaction mode of the serial communication unit is set as the pause mode in response to receiving the firmware upgrade instruction sent from the host, may be: in response to receiving the firmware upgrade instruction sent from the host, switching the interaction mode of the serial communication unit from the normal mode to the pause mode according to a preset mode switching instruction, where the preset mode switching instruction may be set by firmware, i.e. by writing a hardware register.
Before the firmware upgrade is performed, valid data (such as running data processing data recorded, etc) of various units in the solid state disk may be stored first. Thus, before the interaction mode of the serial communication unit is set as the pause mode, valid data of the internal process interaction unit, valid data of the CPU processing unit, valid data of the serial communication unit, valid data of the memory processing unit and valid data of the control peripheral unit may be respectively stored in the storage unit, such that after the firmware upgrade is completed, it can be ensured that valid data in the solid state disk is not lost.
In some embodiments of the present disclosure, it is also possible to check whether the solid state disk is currently suitable for a firmware upgrade operation before the firmware upgrade is performed. Then, after the interaction mode of the serial communication unit is set as the pause mode and before the CPU processing unit is triggered to perform power-down processing, a timer in the CPU processing unit may be controlled to be initiated; and if it is not detected within a preset detection duration that the processing of the firmware upgrade instruction is completed, it is determined that there is an upgrade exception (the upgrade exception of the solid state disk includes but is not limited to the solid state disk being in a read-only operating mode or a temperature of the solid state disk is greater than or equal to a preset temperature threshold) in the solid state disk, the interaction mode of the serial communication unit is switched from the pause mode to the normal mode, and the firmware upgrade to the solid state disk is canceled. By checking in advance whether the solid state disk is currently suitable for the firmware upgrade, the firmware upgrade is avoided in the case where the solid state disk does not currently allow to perform the firmware upgrade.
After the interaction mode of the serial communication unit is switched from the pause mode to the normal mode, it is also possible to send upgrade exception information about the solid state disk to the host, and stop receiving a next firmware upgrade instruction sent from the host. On the one hand, it is possible to let a person using the host know that there is an exception condition currently existing in the solid state disk; on the other hand, it is possible to stop receiving and processing instructions sent from the host before the exception is solved.
In some embodiments of the present disclosure, if it is detected within a preset detection duration that the processing of the firmware upgrade instruction is completed, it can be determined that there is no upgrade exception currently in the solid state disk, and the CPU processing unit can be triggered to perform power-down processing, such that firmware upgrade is ensured to be performed under the condition that the solid state disk is suitable for firmware upgrade.
After the CPU processing unit is triggered to perform power-down processing, the timer in the CPU processing unit can also be controlled to be shut down, and the CPU processing unit is switched to the standby state so as to prepare for a subsequent firmware upgrade.
In step 202, the CPU processing unit is triggered to perform power-down processing, and the internal process interaction unit, the storage unit, the memory processing unit and the control peripheral unit are controlled to be switched to a standby state.
In a specific implementation, the CPU processing unit can be triggered to perform power-down processing, the serial communication unit is controlled to pause information interaction with the host, in response to the power-down processing being initiated in the CPU processing unit, the internal process interaction unit, the storage unit, the memory processing unit and the control peripheral unit are all controlled to be switched to the standby state. By switching various units to the standby state, it can ensure the consistency of the memory data in the solid state disk before and after the upgrade, and ensure that there is no internal information interaction inside the solid state disk before the upgrade is completed.
In some embodiments of the present disclosure, the internal process interaction unit may include an internal information interaction network that is used by various hardware units inside the solid state disk to perform information interaction. In this case, the step, in which the CPU processing unit is triggered to perform power-down processing, and the serial communication unit is controlled to pause information interaction with the host, may be: triggering the CPU processing unit to perform power-down processing, controlling the serial communication unit to pause information interaction with the host while clearing the interaction information in the internal information interaction network. Moreover, before clearing the interaction information in the internal information interaction network, the interaction information in the internal information interaction network can also be stored in the storage unit, such that the interaction information can be saved before the interaction information of each unit in the solid state disk is cleared, so as to avoid data loss.
In some embodiments of the present disclosure, the internal process interaction unit includes an internal information interaction network, then the step, in which power-down processing is initiated by the CPU processing unit, and the internal process interaction unit, the storage unit, the memory processing unit and the control peripheral unit are all controlled to be switched to a standby state, may be: initiating a disabling operation for the storage unit, the memory processing unit and the control peripheral unit, switching the internal process interaction unit to the standby state, and pausing information interaction of the internal information interaction network, so that other actions having nothing to do with firmware upgrade in the solid state disk can be paused, preventing an exception from occurring during a subsequent reset operation, ensuring the consistency of memory data in the solid state disk before and after the upgrade, improving the reliability of the upgrade, and ensuring that no internal information interaction exists inside the solid state disk before the upgrade is completed.
In step 203, on the basis of the standby state, a system reset operation for the solid state disk is triggered, and firmware upgrade is performed on the solid state disk according to the firmware upgrade instruction.
After units in the solid state disk are switched to the standby state, the system reset operation for the solid state disk can be triggered, and firmware upgrade is performed on the solid state disk according to the firmware upgrade instruction, so as to complete the switching from an old version of firmware to a new version of firmware and realize the online upgrading of the solid state disk.
In some embodiments of the present disclosure, the firmware upgrade instruction may contain firmware version information, then firmware upgrade may be performed on the solid state disk by using the firmware version information.
In step 204, in response to the firmware upgrade being completed, initialization processing is performed on the CPU processing unit, the internal process interaction unit, the storage unit, the memory processing unit and the control peripheral unit respectively, and the pause mode of the serial communication unit is canceled.
After the online firmware upgrade of the solid state disk is completed, initialization processing can be performed on units in the solid state disk, and the pause mode of the serial communication unit is canceled, so as to restore the normal interaction mode between the host and the solid state disk. In response to the completion of the firmware upgrade, initialization processing can be performed on the CPU processing unit, the internal process interaction unit, the storage unit, the memory processing unit and the control peripheral unit, respectively, and the pause mode of the serial communication unit is canceled, so that the solid state disk is in a re-initialized state through the initialization processing on each unit. It is not necessary to maintain the state before the upgrade and to resume the information interaction before the upgrade, thus the online upgrading can be completed in seconds without interrupting services, which greatly simplifies the boundary processing of the new version of firmware and improves the simplicity of firmware switching and upgrade efficiency.
In some embodiments of the present disclosure, message cache queues of hardware units in the solid state disk may be stored in the internal process interaction unit. Then, the initialization processing may be respectively performed on the CPU processing unit, the internal process interaction unit, the storage unit, the memory processing unit and the control peripheral unit by: performing initialization processing on a message cache queue of the CPU processing unit, a message cache queue of the internal process interaction unit, a message cache queue of the storage unit, a message cache queue of the memory processing unit and a message cache queue of the control peripheral unit, respectively.
In some embodiments of the present disclosure, the message cache queue may at least include a starting queue recording variable Head and an ending queue recording variable Tail. Then, the message cache queue of the CPU processing unit, the message cache queue of the internal process interaction unit, the message cache queue of the storage unit, the message cache queue of the memory processing unit and the message cache queue of the control peripheral unit are initialized respectively by: performing initialization processing on the starting queue recording variable Head and the ending queue recording variable Tail of each message cache queue respectively. By performing initialization processing on the message cache queues of various units, the solid state disk can be in a re-initialized state, it is not necessary to maintain the state before the upgrade and to resume the information interaction of the message cache queue before the upgrade. Therefore, the online upgrading can be completed in seconds without interrupting services, which greatly simplifies the boundary processing of the new version of firmware, and improves the simplicity of firmware switching and upgrade efficiency.
In some embodiments of the present disclosure, the pause mode of the serial communication unit is canceled by: switching the interaction mode of the serial communication unit from the pause mode to the normal mode. After the pause mode of the serial communication unit is canceled, the firmware upgrade result may also be returned to the host such that a person using the host can know the firmware upgrade result in a timely manner.
It should be noted that the embodiments of the present disclosure include but are not limited to the above-mentioned examples, and it can be understood that those skilled in the art would have been able to make arrangements according to actual needs under the guidance of the idea of the embodiments of the present disclosure, which is not limited in the present disclosure.
In the embodiment of the present disclosure, an online upgrading method for a solid state disk is provided, where the solid state disk includes at least an internal process interaction unit, as well as a CPU processing unit, a serial communication unit, a storage unit, a memory processing unit and a control peripheral unit that are respectively in communication connection with the internal process interaction unit. The solid state disk is in communication connection with a host via the serial communication unit. Firstly, in response to receiving a firmware upgrade instruction sent from the host, an interaction mode of the serial communication unit is set as a pause mode so as to ensure that no instruction sent from the host is received before the upgrade is completed. Next, the CPU processing unit is triggered to perform power-down processing, each unit in the solid state disk is controlled to be switched to a standby state so as to ensure data consistency before and after the upgrade, and to ensure that no internal information interaction exists in the solid state disk before the upgrade is completed. Next, a system reset operation is triggered for the solid state disk on the basis of the standby state, and firmware upgrade is performed on the solid state disk according to the firmware upgrade instruction. Finally, in response to the firmware upgrade being completed, initialization processing is performed on units in the solid state disk, and the pause mode of the serial communication unit is canceled.
