Understanding the OST CLI Commands
The OpenStorage Transport (OST) --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).
•
auto (--mode auto)
DR will set the deduplication to Dedupe or Passthrough, based on the client's number of cores and whether it is 32–
or 64–bit.
These OST commands are used in the following format: ost --update_client --name --mode.
NOTE: If an OST client has four or more CPU cores, it is considered to be dedupe-capable. However, the OST
client operating mode depends upon how it is configured in the DR Series system (Dedupe is the default OST
client mode). If the administrator did not configure an OST client to operate in a specific mode and it is dedupe-
capable, it will run in the Dedupe mode. If an OST client is not dedupe-capable (meaning the OST client has less
than four CPU cores), and the administrator sets it to run in the Dedupe mode, it will only run in the Passthrough
mode. If an OST client is set to run in Auto mode, the OST client will run in the mode setting determined by the
media server. The following table shows the relationship between the configured OST client mode types and the
supported client mode based on client architecture type and corresponding number of CPU cores.
