The battery charge cannot reach 100%. The main reasons for the software are as follows:1. The battery itself is aging2. Original management software and driveBattery agingAfter the battery is used for a period of time, the battery will produce loss, which will cause the internal power to gradually decrease, and may cau

after the power outage, a rechargeable battery is applied to the array card buffer unit. Today, most of the array card cache units add a rechargeable battery pack, which provides power support for the cache after a power outage, while ensuring that the data is not lost for a certain amount of time (typically 48 hours). Until the next time the server recovers power again, the array card controller will flus
