Limiting transmission bandwidth
You can set a fixed bandwidth limit or a bandwidth schedule.
1. With a fixed bandwidth limit, data will be transmitted at all times according to the
user-specified bandwidth configuration. If you want to set a fixed bandwidth limit,
use the limit bandwidth command.
Command LIMIT BANDWIDTH
Description
Sets a fixed bandwidth limitation for transmitting data from the
source to the target
Syntax LIMIT BANDWIDTH <bytes>, <seconds> TO <target>
Options
● bytes—Number of bytes to be transmitted
● seconds—Maximum number of seconds to wait before
transmitting again
● target—Name of the target, an IP address on the target, or a
virtual IP address. Depending on the network route Storage
Mirroring Recover uses to access the target, you may need to
specify the fully qualified domain name.
Examples limit bandwidth 19300, 5 to beta
Notes
● This command transmits in bursts, not bytes per seconds.
The time identifies how long to wait before transmitting again.
For example, if 5 seconds are specified and it only takes 2
seconds to send the specified bytes, Storage Mirroring
Recover will wait an additional 3 seconds before transmitting
again.
● Target names that contain non-alphanumeric characters must
be enclosed in quotation marks.
2. With a scheduled bandwidth limit, data will be transmitted according to the user-
specified schedule and the user-specified bandwidth configuration. Implementing
a schedule requires several steps and DTCL commands. Create a scheduled
event using the limit bandwidth schedule add command.
Command LIMIT BANDWIDTH SCHEDULE ADD
Description
Creates a scheduled bandwidth event for limiting transmission of
data from the source to the target
