Understanding the OST CLI Commands
The
--mode
component supported in the DR Series system command line interface (CLI) command supports three
values, which represent optimized writes done via:
•
deduplication (
--mode dedupe
) The client will process hashing on data, so deduplication processing occurs on the
server side (client-side deduplication).
•
passthrough (
--mode passthrough
) The client will pass all data to DR for deduplication processing (appliance-side
deduplication).
