Description
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a storage server power-down protection device and method.
Background
In a modern computer system architecture, a volatile memory is generally adopted as a data cache for acceleration, and in the case of abnormal power failure, data in a cache cannot be stored in a nonvolatile memory before the cache, so that data loss is easily caused, and the safety and consistency of the data cannot be ensured. Currently, there are three mainstream power failure protection methods: the UPS (uninterrupted power supply) is mainly applied to a storage center, and when the input of an external power supply is normal, the UPS charges the UPS when the electric quantity is not enough and supplies power to electric equipment normally. When the external power supply is abnormally powered off, the UPS converts the electric energy in the battery into alternating current through inversion to maintain the continuous operation of the electric equipment, and the storage server stores the cache data into the hard disk and closes the service, so that the data safety is ensured. The other is a BBU (Battery Backup Unit) standby power Unit which is used in a single machine and can provide electric energy for the system to store and cache data, or ensure that a server part circuit continuously operates for a period of time, generally short time, usually not more than tens of seconds, and the system stores the data in the period of time until the external power supply is recovered. And a nonvolatile memory NVDIMM is used, the nonvolatile memory has the characteristic of no loss of power-down data, and when the system is powered on again, the controller can recover the data, so that the cache data is not lost. In the above 3 modes, the UPS has a large occupied space and a high cost due to the inverter, the rectifier circuit, and the like. The BBU only supplies power to partial circuits, so that the size is relatively small, the protection time is generally short, a power supply control circuit is complex, and the technical implementation difficulty is high. The NVDIMM is a novel storage device, the function of the NVDIMM needs to be fully played, the design of an original storage server memory circuit needs to be changed, software needs to be adapted to a certain degree, the realization difficulty is high, and the cost is high.
CN102929805A discloses a power-down protection method for a memory system cache, which uses a power module similar to a BBU form to supply power only to components such as a memory and a flash card, but needs to recover data after being powered on again, needs to adapt software and hardware to a certain extent, needs to use a DCDC circuit to convert the power, and has a relatively complex circuit. CN104021093A discloses a power-fail protection method for storage equipment based on NVDIMM, the invention uses NVDIMM storage device to protect cache data, when power failure occurs, the NVDIMM completes data storage, and data recovery is performed when power supply is recovered.

Furthermore, the battery module is always communicated with the power supply of the power supply module in the operation process of the device, and when the battery voltage of the battery module is lower than that of the power supply module, the battery module is automatically charged and always keeps in a full-charge state.
