Dell PowerVault Storage Area Network - Ost -Limit -Speed <<Num><Kbps | Mbps | Gbps | Default> -Target <Ip Address | Hostname; Ost -Help

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.
Table 2. Supported OST Client Modes and Settings

Passthrough Supported Supported Supported Supported
Syntax
ost --update_client --name acme-81 --mode dedupe
NOTE: You may be able to force writes for OST clients running in the Passthrough mode using the DR Series
system CLI mode --dedupe command. The change in OST client mode is effective on the next backup operation
when you are using the Symantec NetBackup (or if you are using the Symantec Backup Exec, you will need to
restart this service for it to recognize that a new mode has been configured).
Result
OST client updated successfully.
ost --limit --speed <<num><kbps | mbps | gbps | default> --target <ip address | hostname>
Description
Limits the bandwidth consumed by OST (OpenStorage Technology) for a system you define by IP address or hostname
(--target), by which you define the speed in kilobytes/second (KBps), megabytes/second (MBps), gigabytes/second
(GBps), or an unlimited bandwidth (default).
Syntax
ost --limit --speed 10mbps --target acmesys-49
Result
Successfully updated bandwidth limit for acmesys-49 to 10 MBps.
Changing traffic control policies ... done.
ost --help
Description
Displays the list of OpenStorage Technology (OST) ost-related options that can be used as a reference when using the
DR Series system CLI.
