Detailed Description
The invention provides a power supply device of a unified storage array and the unified storage array, which can realize seamless switching of a main power supply module and a standby power supply module, ensure the reliability of the unified storage array and simplify the power supply logic and power supply architecture of the unified storage array.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply device of a unified storage array according to the present invention, where the power supply device includes a control module, a standby power supply module 02, and N main power supply modules, where N is an integer not less than 2;
the public end connected with the output end of each main power supply module is connected with the power supply end of a first load and the power supply end of a second load, and the output end of the standby power supply module 02 is connected with the power supply end of the second load, wherein the first load is a load which needs data backup in the unified storage array after the power failure of the main power supply modules, and the second load is a load which does not need data backup in the unified storage array after the power failure of the main power supply modules;
the control module is used for controlling the preparation power supply module 02 to supply power for the second load when detecting that the abnormal power supply module exists in the N main power supply modules.
When the power supply device of the unified storage array in the prior art realizes redundant power supply, generally, one PSU is used as a main power supply module, one BBU is used as a standby power supply module 02, and a cold backup power supply mode is adopted, namely, when the main power supply module is abnormal, the main power supply module is switched to the standby power supply module 02, but because a certain time interval exists during switching, seamless switching between the main power supply module and the standby power supply module 02 cannot be realized, and therefore, the data loss of the unified storage array can be possibly caused.
Therefore, the application provides a power supply device of a unified storage array, which comprises a standby power supply module 02 and N main power supply modules, wherein under normal conditions, the N main power supply modules supply power to a first load and a second load at the same time, and N is an integer not less than 2, namely, the power supply device of the unified storage array comprises two or more main power supply modules, when an abnormal power supply module exists in the main power supply modules, the control module immediately starts the standby power supply module 02, namely, the standby power supply module 02 starts to supply power to the second load as long as the abnormal power supply module appears in the power supply device of the unified storage array. It should be noted that, the specific number of abnormal power supply modules existing in the N main power supply modules detected by the control module is not particularly limited, and the standby power supply module 02 is only required to be turned on before the N main power supply modules are abnormal. Therefore, the standby power supply module 02 is started before the plurality of main power supply modules are abnormal by arranging the plurality of main power supply modules, so that the purpose of switching to the standby power supply module 02 in a seamless manner when the main power supply modules are abnormal is achieved. In addition, the standby power supply module 02 can be started only when an abnormal power supply module exists in the main power supply module, and the service life of the standby power supply module 02 cannot be influenced.
The load in the unified storage array is divided into the first load and the second load, so that the overall architecture of the power supply device is simplified, and the energy consumption of the standby power supply unit is reduced. For example, the fan and network card are the first load and the system disk is the second load. Specifically, a load which does not need to carry out data backup after power failure in the unified storage array is used as a first load, and only each main power supply module is used for supplying power to the first load, and when each main power supply module is abnormal, the first load is passively closed, but the data loss of the unified storage array is not caused, and the reliability of the unified storage array is not influenced; the load which needs to be subjected to data backup after power failure in the unified storage array is used as a second load, each main power supply module and the standby power supply module 02 are commonly utilized to supply power for the second load, and when an abnormal power supply module exists in the main power supply module, the standby power supply module 02 is started, so that the loss of data of the unified storage array caused by the fact that the data backup cannot be performed by the second load is avoided, and the reliability of the unified storage array is improved.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply device for a unified memory array according to the present invention, and fig. 1 illustrates that the power supply device includes two main power supply modules, and each main power supply module includes two main power supplies 11. It should be further noted that the number of the main power supply modules in the present application may be 2, and when one of the main power supply modules is abnormal, the standby power supply device is immediately started, so that even if two main power supply modules are abnormal, the unified storage array will not face the risk of data loss. In addition, the probability of abnormality of the main power supply modules in practical application is smaller, and the probability of abnormality of the two main power supply modules is further reduced, so that 2 main power supply modules designed for the unified storage array can simplify the power supply architecture of the power supply device of the unified storage array on the basis of effectively improving the reliability of the unified storage array.
In summary, the application provides a power supply device of a unified storage array, including a control module, a standby power supply module 02 and N main power supply modules, when an abnormal power supply module exists in the main power supply module, the standby power supply module 02 is immediately started to supply power for a second load, so that the time difference that the standby power supply module 02 is started again after the main power supply module is powered off is eliminated, the data of the unified storage array is ensured not to be lost, and the reliability of the unified storage array is improved. And according to whether the main power supply module needs to carry out data backup after power failure, the loads in the unified storage array are divided into a first load and a second load, and the standby power supply module 02 only supplies power for the second load, so that power supply logic and power supply architecture are simplified.
Based on the above embodiments:
as a preferred embodiment, the main power supply module includes a power supply plane ORing circuit 12 and M main power supplies 11, M being an integer not less than 2;
the output terminals of the main power sources 11 are connected and the connected common terminal is connected to the input terminal of the power plane ORing circuit 12, and the output terminal of the power plane ORing circuit 12 serves as the output terminal of the main power supply module.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply device for a unified memory array according to the present invention, and fig. 1 illustrates that the power supply device includes two main power supply modules, and each main power supply module includes two main power supplies 11. In this embodiment, each main power supply module includes two or more main power supplies 11, so when one part of the main power supplies 11 fails, the main power supply module can also supply power to the first load and the second load through another part of the main power supplies 11, and when all the main power supplies 11 in the main power supply module are abnormal, the power supply device can also supply power to the first load and the second load through other main power supply modules, so the reliability of the power supply device for supplying power to the unified storage array is further improved.
And, each main power supply device includes a power supply plane ORing circuit 12, and the public end of each main power supply 11 in each main power supply device after the output end is connected to the first load and the second load through the power supply plane ORing circuit 12, because the power supply plane ORing circuit 12 is a unidirectional conductive circuit, current backflow can be prevented, current sharing of each main power supply device is realized, and therefore the safety of the power supply device of the unified storage array can be further improved, and the reliability of the unified storage array is further ensured. The specific circuit configuration of the power supply plane ORing circuit 12 is not particularly limited in this application.
As a preferred embodiment, further comprising:
the input end is connected with the output end of the main power supply module, and the output end is connected with the power supply end of the first load and the power supply end of the second load, and is used for inhibiting the surge current of the output end of the main power supply module.
Considering that the current at the output end of the main power supply module may fluctuate during the actual application process, the first load and the second load may be damaged when the current is too large, so the hot plug protection module 03 is disposed between the main power supply module and the load in the embodiment. Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply device for a unified memory array according to the present invention, and fig. 1 illustrates that the power supply device includes two main power supply modules, and each main power supply module includes two main power supplies 11. For example, when the main power supply module is started instantly or the current on the public end connected with the main power supply module is fluctuated instantly, namely surge current is generated due to abnormality of the main power supply module, the surge current is eliminated through the hot plug protection module 03, so that the first load and the second load are protected from being influenced, and the safety and the reliability of the unified storage array are ensured.
The specific structure of the hot plug protection module 03 is not particularly limited, and may be any one as long as the function of suppressing the surge current at the output end of the main power supply module is satisfied.
In this embodiment, a hot plug protection module 03 is disposed between the output end of the main power supply module and the power supply end of the first load, where the hot plug protection module 03 can inhibit the surge current on the output end of the main power supply module, so as to protect the safety of the first load and the second load.
As a preferred embodiment, the power supply circuit further comprises a main power supply ORing circuit 04 and a standby power supply ORing circuit 05;
the input end of the main power supply ORing circuit 04 is connected with a common end connected with the output end of each main power supply module, and the output end is connected with the power supply end of the second load;
the input end of the standby power ORing circuit 05 is connected with the output end of the standby power supply module 02, and the output end is connected with the power supply end of the second load.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply device for a unified memory array according to the present invention, and fig. 1 illustrates that the power supply device includes two main power supply modules, and each main power supply module includes two main power supplies 11. In this embodiment, a main power supply ORing is disposed between a public end connected to an output end of the main power supply module and a power supply end of the second load, a standby power supply ORing is disposed between an output end of the standby power supply module 02 and the public end of the second load, and the main power supply ORing circuit 04 and the standby power supply ORing circuit 05 are unidirectional conductive circuits, and have functions of backflow prevention and current sharing, so that safety of the second load can be ensured, and reliability of the unified storage array is further improved.
In addition, when the hot plug protection module 03 is provided at the common end to which the output ends of the respective main power supply modules are connected, the main power supply ORing circuit 04 needs to be provided between the output end of the hot plug protection module 03 and the power supply end of the second load. At this time, the power supply device of the unified storage array can simultaneously ensure that the main power supply module is not influenced by current backflow, ensure that the first load and the second load are not influenced by surge current existing on the output end of the main power supply module and ensure that the second load is not influenced by current backflow, thereby improving the reliability of the power supply device of the unified storage array and ensuring the safety of the unified storage array.
The specific circuit configurations of the main power supply ORing circuit 04 and the standby power supply ORing circuit 05 are not particularly limited in the present application.
As a preferred embodiment, the standby power supply module 02 includes a battery 21, a first sampling module 22, a bypass output module 23, and a buck output module 24;
the first sampling module 22 is configured to detect an output voltage of the battery 21, and control the step-down output module 24 to be turned on when the output voltage is greater than a preset output voltage threshold, so that the step-down output module 24 adjusts an actual output voltage of the battery 21 to the preset output voltage threshold and outputs the adjusted actual output voltage to the second load; when the output voltage is not greater than the preset output voltage threshold, the bypass output module 23 is controlled to be turned on so as to output the output voltage of the battery 21 to the second load through the bypass output module 23.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a standby power supply module 02 according to the present invention. In this embodiment, a specific implementation structure of the standby power supply module 02 is provided, where the standby power supply module 02 includes a battery 21, a first sampling module 22, and a bypass output module 23 and a step-down output module 24. Considering that the output voltage of the battery 21 may be higher than the working voltage of the second load when the battery 21 is used to supply power to the second load, or may even cause the second load to be burned out, the first sampling module 22 is provided in this embodiment, where the first sampling module 22 is capable of collecting the output voltage of the battery 21, and if the output voltage is greater than the preset output voltage threshold (the specific value of the preset output voltage threshold is not particularly limited in this application, for example, the specific value of the preset output voltage threshold may be set to the working voltage of the second load, for example, 12.6V), the step-down output module 24 is controlled to be turned on, and the step-down output module 24 steps down the output voltage of the battery 21 to the first preset output voltage and then outputs the second load, so as to ensure that the second load can work normally. When the first sampling module 22 detects that the output voltage of the battery 21 is not greater than the preset output voltage threshold (for example, the output voltage is less than 11.6V), the bypass output module 23 is controlled to be turned on, and the bypass output module 23 directly transmits the output voltage of the battery 21 to the second load since the normal operation of the second load is not affected. In addition, the specific circuit structure of the BUCK output module 24 is not particularly limited in this application, and may be, for example, a four-switch BUCK-BOOST circuit.
In addition, fig. 2 further includes a second sampling module, where the second sampling module may be used to collect an output voltage of the backup power supply module, a charging input voltage (i.e. a voltage input to the charging module), a charging input current (i.e. a current input to the charging module), and the like, which is not limited in this application.
In summary, the standby power supply module 02 provided in this embodiment can select a corresponding output circuit according to the output voltage of the battery 21, when the output voltage of the battery 21 is too large, the step-down output module 24 first adjusts the output voltage of the battery 21 to a preset voltage output threshold, and then provides the voltage to the second load, so as to fully ensure the safety of the second load and ensure that the data of the unified storage array cannot be damaged. The output voltage of the battery 21 is supplied to the second load directly through the bypass output module 23 when appropriate. The stability and the safety of supplying power to the unified storage array are guaranteed in all aspects.
As a preferred embodiment, the power supply module further includes:
a charging module for charging the battery 21 when it is detected that the output voltage of the battery 21 is smaller than the first output voltage value.
Considering that the power of the battery 21 itself gradually decreases during the process of charging the second load by the standby power supply module 02, and the step-down output module 24 also consumes a part of the power provided by the battery 21, it is also necessary to charge the battery 21 when the power of the battery 21 itself is insufficient in order to ensure that the second load can be normally supplied. The specific structure of the charging module is not particularly limited, and may include, for example, a BUCK circuit, a BUCK-BOOST circuit, and a BOOST circuit at the same time, and an appropriate circuit may be selected according to the charging input voltage.
In addition, the charging module is specifically configured to precharge the battery 21 when detecting that the output voltage of the battery 21 is less than the first output voltage value, charge the battery 21 with a constant current when the output voltage of the battery 21 is between the first output voltage value and the second output voltage value, and charge the battery 21 with a constant voltage when the output voltage of the battery 21 is between the second output voltage value and the third output voltage value, where the first output voltage value, the second output voltage value, and the third output voltage value are sequentially increased.
In this embodiment, the charging process of the battery 21 is divided into three stages according to the actual output voltage of the battery 21, and when the electric quantity of the battery 21 is low, that is, the output voltage of the battery 21 is smaller than the first output voltage value, the battery 21 is precharged, that is, the restorative charging is performed, so as to ensure the service life of the battery 21; when the output voltage of the battery 21 rises to the second output voltage value, constant-current charging is performed on the battery 21, so that the charging efficiency of the battery 21 is improved through larger current; the battery 21 is charged at a constant voltage immediately before the battery 21 is fully charged, that is, after the output voltage of the battery 21 reaches the third output voltage value, so that the problem of overcharging the battery 21 can be avoided.
In summary, in this embodiment, the charging process of the battery 21 is divided into three stages, so that the battery 21 is charged while the safety of the battery 21 is ensured, and the safety and reliability of the unified storage array are further ensured.
As a preferred embodiment, the charging module is specifically configured to charge the battery when it is detected that the battery meets a preset charging condition and the output voltage of the battery is smaller than the first output voltage value;
the preset charging condition is any one or a combination of more than one of cell balance of the battery, temperature of the battery within a preset temperature range and normal link of the battery for charging and discharging.
In this embodiment, in order to ensure the safety of the charging module for charging the battery, before formally charging the battery, the charging module further detects whether the battery meets preset charging conditions, where the preset charging conditions include whether the battery cell is balanced, whether the temperature of the battery is within a preset temperature range, and whether the link of the battery for charging and discharging is normal, for example, when it is determined that the voltage difference between the battery cells is less than 0.2V, the balance of the battery cell is determined, when the temperature of the battery is between 0 ℃ and 60 ℃, the temperature of the battery is determined to be normal, and when the MOS transistor on the link of the battery for charging and discharging can work normally, the link of charging and discharging is considered to be normal. When the battery reaches a full charge condition, the charging module stops charging the battery, for example, the full charge condition can be that the voltage of the battery is higher than a full charge voltage value, and the current charged by the charging module is smaller than a preset current value and the duration is longer than a preset duration. In addition, the charging module can also generate alarm prompt information when the battery abnormality is detected so as to remind operation and maintenance personnel of timely maintaining or replacing the battery.
As a preferred embodiment, the control module is further configured to detect any one or more of the backup capacity, the output voltage, the output current, the cell temperature, and the cell voltage of the backup power module 02.
Considering that, in practical applications, as the service life of the standby power supply module 02 gradually increases, the performance of the battery 21 in the standby power supply module 02 gradually decreases, so in order to ensure that the standby power supply module 02 can normally supply power to the second load, in this embodiment, the control module further detects relevant parameters that affect the power supply performance of the standby power supply module 02, such as the standby capacitance, the output voltage, the output current, the battery cell temperature, and the battery cell voltage of the standby power supply module 02. The frequency of the control module detecting each relevant parameter of the standby power supply module 02 is not particularly limited, and may be set according to actual situations.
As a preferred embodiment, the control module is further configured to determine whether the standby power supply module 02 meets a preset power supply condition, and detect whether each main power supply module is normal when the standby power supply module 02 meets the preset power supply condition;
the preset power supply condition includes whether the model of the standby power supply module 02 is matched with the model of the second load and/or whether the standby power supply module 02 can normally supply power.
In order to ensure the safety and reliability of the standby power supply module 02 supplying power to the second load, in this embodiment, the control module detects whether the standby power supply module 02 satisfies a preset power supply condition, so as to avoid the problem that the standby power supply module 02 and the second load are not matched and cannot normally supply power to the unified storage array when the main power supply module is abnormal. Specifically, in this embodiment, the preset power supply condition includes whether the model of the standby power supply module 02 matches the model of the second load, for example, whether the output voltage of the standby power supply module 02 meets the requirement for the voltage when the second load works. The preset power supply conditions further include whether the standby power supply module 02 can normally supply power to the second load, if the standby power supply module 02 fails, the standby power supply module 02 cannot supply power to the second load, which may result in the risk that the unified storage array faces data loss, so that when the standby power supply module 02 is determined to be capable of normally supplying power to the second load, whether an abnormal power supply module exists in the main power supply module is detected, and whether the standby power supply module 02 needs to be started is determined. In addition, when the control module detects that the standby power supply module 02 does not meet the preset charging condition, a prompt alarm message may be generated to repair or replace the standby power supply module 02.
In summary, the present embodiment further ensures the reliability of the power supply device for supplying power to the unified storage array by detecting whether the standby power supply module 02 meets the preset charging condition.
The application also provides a unified storage array, comprising the power supply device of the unified storage array and a unified storage array body.
The application provides a unified storage array, including control module, reserve power module 02 and N main power module, open reserve power module 02 immediately when there is unusual power module in the main power module and supply power for the second load, consequently eliminated the time difference that main power module turned on reserve power module 02 again after the power failure, guarantee that unified storage array's data can not lose, promote unified storage array's reliability. And according to whether the main power supply module needs to carry out data backup after power failure, the loads in the unified storage array are divided into a first load and a second load, and the standby power supply module 02 only supplies power for the second load, so that power supply logic and power supply architecture are simplified.
