Adaptec AFM-700 Flash Module Kit

The AFM-700 features NAND flash memory and super capacitor technologies that work together to save cached data in the event of system power loss. The super capacitor charges while the system is booting. When the module detects loss of power, the super capacitor keeps critical parts of the RAID adapter active long enough to allow data to be copied from the onboard adapter cache to the flash memory. The flash memory can store data for years without power. When power is returned, the data is copied back to the onboard adapter cache and operation resumes as normal with all outstanding I/O requests intact.
