Cache data protection during power failures - Cache Guard

Redundantly configured batteries inside ETERNUS AF/ETERNUS DX allow data in cache memory to be moved to nonvolatile memory or to physical disk drives in cases of power failure. This secured data can then be maintained in that state indefinitely.
And ETERNUS AF and ETERNUS DX (S3 or later) have long-life Nickel-metal-hydride battery for backup so as to reduce the periodic replacement parts. This also helps reduce industrial waste.
