8.7.3 REC Buffer
This function displays the REC Buffer status when performing REC in "REC asynchronous consistency mode".
The "Consistency mode" secures the order of data transfer to the remote storage system for all of the specified
REC sessions. This mode requires constant securement of the dedicated REC Buffer in the cache memory.
Copying via REC Buffer stores multiple REC session I/Os in the REC Buffer for a certain period of time, and
copies in blocks.
The ETERNUS DX60 S3 does not support this function.
This function is displayed only when the Advanced Copy function license has been registered, and when
using an ETERNUS DX/AF model that supports REC.
