*1 : The total available capacity of TFOVs for a ETERNUS DX can be expanded by setting an ex-
pansion for the total capacity of TFOVs. If the installed memory is not sufficient, the expansion
setting cannot be performed.
For details on setting an expansion for the total capacity of TFOVs, refer to "ETERNUS CLI Us-
er's Guide".
*2: Storage Cluster Continuous Copy is an ETERNUS DX/AF function that performs a copy on the
Primary storage and the Secondary storage simultaneously, and achieves consistency between
the two storage systems. This is achieved by operating Advanced Copy from a TFOV to a
TFOV.
