Administrator Guide

• 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 a RDA with OST client has four or more CPU cores, it is considered to be dedupe-capable. However, the
client operating mode depends upon how it is configured in the DR Series system (Dedupe is the default RDA with
OST client mode). If the administrator did not configure a client to operate in a specific mode and it is dedupe-
capable, it will run in the Dedupe mode. If a client is not dedupe-capable (meaning the 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 a
client is set to run in Auto mode, the client will run in the mode setting determined by the media server. The
following table shows the relationship between the configured client mode types and the supported client mode
based on client architecture type and corresponding number of CPU cores.
