Cache data integrity maintenance during power outage - Cache Protector

ETERNUS DX and ETERNUS AF guarantee data security even in cases of cashe failure as cache is redundantly configured and constantly mirrored.
If power supply fails ETERNUS DX/ETERNUS AF automatically evacuates controller cache placing data in nonvolatile memory. An SCU(System Capacity Unit) [1] provides sufficient power to always ensure all data is evacuated successfully. Then the nonvolatile memory protects the data indefinitely.

Importantly, toxic waste is also reduced by the use of permanent SCU in place of periodically replaceable batteries.

Cashe protector

  • [1]An electrical double layer condenser unit only used for cache data backup. To supply power to devices during a power outage, connection of devices to a UPS (non-stop power device) is required.

Benefits

  • Guarantees security of data in cache even in cases of power failure.
