Problems solved by technology

For example, the anti-backflow circuit 4 composed of the driver chip LM5050MK-2 and the NMOS transistor CSD16415 needs at least 2ms from the time when the output voltage of the LM5050MK-2 is lower than the input voltage to the time when the NMOS is fully turned on. Cause the combined circuit voltage P12V_AUX to drop instantaneously, thus affecting the stability of the system

Embodiment Construction

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative work fall within the protection scope of the present application.

[0033] The core of the present application is to provide a power supply control method, device and medium for a storage system. After the storage system is powered off, after the BBU receives the first preset duration of the power supply switching signal sent by the CPLD, the Buck circuit in the BBU is controlled to output more than The first output voltage of the output voltage when the PSU is normally powered, thereby turning on the anti-backflow...

Abstract

The invention relates to the field of storage systems, and discloses a power supply control method and device for a storage system, and a medium, and the method comprises the steps: obtaining a switching power supply signal sent by a CPLD when the storage system is powered down, and controlling a Buck circuit in a BBU to output a first output voltage after the switching power supply signal is received for a first preset time length, so as to switch on an anti-backflow circuit at the BBU side, the first output voltage is greater than the PSU output voltage. Therefore, according to the technical scheme provided by the invention, when the switching power supply signal is received, the Buck circuit in the BBU is controlled to output the first output voltage greater than the output voltage of the PSU, so that the anti-backflow circuit on the BBU side is switched on in advance, the combined voltage of the PSU and the BBU is prevented from instantaneously dropping, the downtime of the storage system is avoided, and the stability of the system is improved.

Description

technical field [0001] The present application relates to the field of storage systems, and in particular, to a power supply control method, device and medium for a storage system. Background technique [0002] In a storage system, the power supply unit (PSU) supplies power to the entire storage system. When the alternating current (AC) 220V is powered off (a term for equipment that cannot work normally due to power failure, power failure, or the quality of the power does not meet the requirements) ), the storage system will switch from the PSU to the battery backup unit (BBU for short) to temporarily supply power to avoid data loss in the storage system due to power failure. [0003] figure 1 A structural diagram of a combined control circuit provided by the present application, such as figure 1 As shown, PSU1 and BBU2 switch power supply through a combined control circuit. When AC220V is powered off, PSU1 sends an AC_FAIL signal to CPLD3. After CPLD3 receives this signal...
