BIOS and CPU to quickly backup memory RAM data to the flash module. In order to quickly
move data from memory RAM to flash module, M.2 PCI‐Express interface flash module is
selected for better performance and less power consumption. In Cache‐to‐Flash recovery phase,
BIOS will check C2F flag status. If C2F flag is ON, I/O cache data will be recovered from the M.2
flash module and then continue normal booting. If C2F flag is OFF, the normal booting process
continues. Compared with traditional BBM solution of 72 hours standard, Cache-to-Flash
technology is more efficient, less risky and consumes less power.
