NOTE: The RDA plug-in is installed by default if you are running the latest version of Dell NetVault Backup
(NVBU). You must download and install the RDA plug-in for NVBU only if there is a plug-in version mismatch
between the DR Series system software and NVBU.
This page displays an RDS or OST Clients Summary table that lists the following types of RDS or OST client-related
information:
Name — lists client by name
Type — lists client type
Plug-In — lists plug-in type that is installed on the client
Backup Software — lists backup software used with this client
Idle Time — lists the idle time for this client
Connection — lists the number of connections for this client
Mode — lists the mode types that can be set for this client:
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.
Passthrough: The client will pass all data to DR for deduplication processing (appliance-side deduplication).
Dedupe: The client will process hashing on data, so deduplication processing occurs on the server side (client-
side deduplication).
If an OST or RDS client has four or more CPU cores, it is considered to be dedupe-capable. However, the OST or RDS
client operating mode depends upon how it is configured in the DR Series system (Dedupe is the default RDA client
mode).
If the administrator did not configure an OST or RDS client to operate in a specific mode and it is dedupe-capable, it
will run in the Dedupe mode.
If an OST or RDS client is not dedupe-capable (meaning the OST or RDS 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 or RDS client is set to run in Auto mode, the OST or RDS client will run in the mode setting determined by
the media server.
The following table shows the relationship between the configured OST or RDS client mode types and the supported
client mode based on client architecture type and corresponding number of CPU cores.
