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:
passthrough (--mode passthrough), and auto (--mode auto). These OST commands are used in the following format: ost
--update_client --name --mode.
NOTE: If an OST client has four or more CPUs, 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
CPUs), 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 CPUs.
