ARC-1883-CAP Flash-based Backup Module

 

The ARC-1883-CAP features NAND flash memory and super capacitor technology that work together to save cached data in the event of system power loss. The super capacitor charges while the system is booting to provide instant cache protection upon start-up. When the module detects loss of power, the super capacitor keeps critical parts of the ARC-1883 RAID controller active long enough to allow data to be copied from the on-board controller cache to the flash memory. The super capacitor charges while the system is booting to provide instant cache protection upon startup, and is fully charged within minutes. 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. Once the data has been copied, the flash memory can store it for years without power. When power is returned to the RAID adapter, the data in the flash memory is copied back to the onboard adapter cache and operation resumes as normal with all outstanding I/O requests intact.
