Abstract

The embodiment of the invention discloses a power consumption test method, device and computer-readable storage medium during data backup of a storage system. The CPLD module cuts off the power supply of peripheral equipment in the storage system, and controls the storage system to perform data backup. The mains failure is simulated by adjusting the storage system to the corresponding operation mode under the mains failure. In this simulated state, only the operation mode of the storage system is converted, and the power of the storage system is still provided by the mains. Therefore, the power meter can be used to observe the power consumption of the storage system during data backup in real time, and finally obtain the corresponding power consumption value when the storage system completes data backup. The CPLD module simulates the mains failure so that the power meter can be used to measure the actual power consumption of the minimum system when the storage system data is backed up. And the BBU capacity can be reasonably configured according to the actual power consumption, so as to reduce the cost while ensuring the stability of the storage system.

Description

A method, device and medium for testing power consumption during data backup of a storage system

technical field

The invention relates to the technical field of storage systems, in particular to a method, device and computer-readable storage medium for testing power consumption during data backup of a storage system.

Background technique

The current data resources are abundant, so the demand for storage devices is very large. At the same time, the requirements for storage devices are getting higher and higher, and many storage devices are equipped with a backup power supply unit (Battery Backup Unit, BBU), so as to cope with abnormal problems of external power supplies.

Under normal circumstances, the storage system runs on the electric energy provided by the mains. When the mains fails, the complex programmable logic device (Complex Programmable Logic Device, CPLD) in the storage system will control the power module to switch to the BBU, and the BBU will provide power . And in order to avoid data loss caused by mains failure, the storage system will perform data backup. In order to save cost and space, an infinitely large BBU cannot be placed in the storage system. In practical applications, the capacity of the BBU is often configured according to the theoretical power consumption of data backup in the storage system. However, there may be a gap between the theoretical power consumption and the actual power consumption. When the actual power consumption of the storage system during data backup is greater than the power consumption provided by the BBU, the data backup cannot be completed, resulting in data loss.

To avoid data loss, a large-capacity BBU can be configured for the storage system, but the cost of the entire storage system will increase accordingly. In order to make the capacity of the configured BBU more reasonable, it is necessary to test the actual power consumption required by the storage system during data backup. However, the BBU is generally placed directly inside the storage system or directly made into an onboard form, and it cannot be tested with a power meter like the power consumption of the whole machine.

It can be seen that how to know the actual power consumption required by the storage system during data backup is an urgent problem to be solved by those skilled in the art.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The structural diagram of the storage system is shown in Figure 1, including a CPLD module, a minimum system module, a power supply unit (Power Supply Unit, PSU), a power supply module (POWER), and a BBU module. The CPLD module controls the power on and off of the entire storage system. The PSU module and the BBU module are respectively connected to the POWER module, and the CPLD module can control the POWER module to switch to the PSU module or the BBU module, that is, to realize switching between the PSU module and the BBU module. Under normal working conditions, the PSU module is connected to the mains to supply power for the storage system. When there is a problem with the mains power, the CPLD module controls the POWER module to switch to the BBU module, and cuts off the power supply of peripheral devices in the storage system. At this time, the BBU module only supplies power to the smallest system module. Among them, the minimum system refers to the minimum unit required to complete important data backup in the storage system, and the minimum system may include a central processing unit (Central Processing Unit, CPU), memory, integrated chip (Platform Controller Hub, PCH), system disk, etc. Because the BBU module is generally placed directly inside the storage system or directly made into an onboard form, it is impossible to use a power meter to directly measure the actual power consumption of the storage system during data backup.

For this reason, the embodiment of the present invention provides a method and device for testing power consumption during data backup of a storage system. The CPLD module simulates a mains failure. In this simulated state, the CPLD module controls the storage system to adjust to the corresponding The operation mode of the system, that is, the CPLD module cuts off the power supply of the peripheral devices in the storage system, and controls the smallest system module for data backup. However, the CPLD module does not control the POWER module to switch to the BBU module. At this time, the PSU module continues to work, and the minimum system module is powered by the mains. When the mains provides power, the power meter can be used to measure the data backup of the storage system. The actual power consumption of the storage system during data backup can be obtained.

S103: Using a power meter, acquire a corresponding power consumption value when the storage system completes data backup.

When simulating a mains failure, only the operation mode of the storage system is converted, and the power of the storage system is still provided by the mains. By setting the power meter between the mains and the PSU module of the storage system, real-time Observe the power consumption of the storage system during backup. When the data backup is completed, the PCH in the smallest system module will send an instruction to the CPLD module indicating that the data backup has been completed, so that the CPLD module can control the shutdown of the storage system. At this time, the power consumption value displayed on the power meter is the storage Actual power consumption of the system for data backup.
