Cache data protection during power failures - Cache Guard

Redundantly configured batteries inside ETERNUS disk storage systems 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.
