Abstract: A redundant data calculation method and apparatus. The method is applied to the redundant data calculation apparatus including a processor and a redundant data calculation unit. In the method, after obtaining to-be-processed data, the processor stores the to-be-processed data in cache space of the redundant data calculation unit. The redundant data calculation unit obtains the to-be-processed data from the cache space and performs calculation for checking the to-be-processed data to obtain redundant data corresponding to the to-be-processed data.

Abstract: A backup power supply method is provided. After detecting a host is powered off, a power-on/off management device in the host powers off elements in the host except a processor, a memory, a backup power hard disk, and a BIOS memory; sets a power-off flag in the power-on/off management device, and sends a reboot instruction to the processor. after receiving the reboot instruction, the processor runs a BIOS program stored in the BIOS memory to initialize the elements in the host except the memory when the power-off flag is detected; store to-be-stored data of the memory into the backup power hard disk; and power off all the elements in the host.
