  • Firehose dump of SRAM write cache data to non-volatile memory using a supercap
    Patent number: 8495321
    Abstract: A mechanism is provided for firehose dumping modified data in a static random access memory of a hard disk drive to non-volatile memory of the hard disk drive during a power event. Responsive an indication of a power event in the hard disk drive, hard disk drive command processing is suspended. A token is set in the non-volatile storage indicating that flash memory in the non-volatile memory contains modified data. A portion of a static random access memory cache table containing information on the modified data in the static random access memory is copied to the flash memory. The modified data from the static random access memory is then copied to the flash memory. Responsive to a determination that the power event that initiated the copy of the modified data in the static random access memory to the flash memory is still present, the hard disk drive is shut down.
