shared memory
Memory that exists logically in the cache. It stores common information about the storage system
and the cache management information (directory). The storage system uses this information to
control exclusions and
differential
table information. Shared memory is managed in two segments
and is used when copy pairs are created.

the data is copied to the cache
flash
memory (SSDs).

.
In the current version of the GUI, "target volume" and "T-VOL" are replaced with "primary volume".
