! Setting a Storage Mirroring Transmission Window —The transmission window establishes a period of availability for all
Storage Mirroring transmissions. You can specify a begin and end time for all Storage Mirroring transmissions. When a
transmission window is in effect, all other start and stop criteria are bound by this window. This means that Storage
Mirroring will never transmit data outside of an established window, regardless of other transmission settings.
For example, if you set a window of availability from 9 p.m. to 4 a.m. and a start option to initiate transmission at 5 a.m.,
the window option will override the start option and no data will be sent at 5 a.m.
Setting Transmission Criteria Using the Management
Console
Transmission criteria allows the user to specify when a transmission will take place. These settings can either be set before
or after a connection is made, and while mirroring and replication are being performed.
Establishing transmission criteria when configuring a connection
After you have configured a source/target connection by following the steps in Establishing a new connection on page 6-7, you
can specify any transmit options by selecting the Transmit tab from the Connection Manager.
The Transmit tab contains four limit types: Bandwidth, Start, Stop, and Window. The transmission options for each limit type
are displayed by highlighting a selection in the Limit Type box.
At the top of the Transmit tab dialog box, the Enable Transmission Limiting check box allows you to turn the transmission
options on or off. You can enable the transmission options by marking the Enable Transmission Limiting check box when
you want the options to be applied, but you can disable the transmission options, without losing the settings, by clearing that
check box.
Also at the top of the Transmit tab dialog box, the Clear All button, when selected, will remove all transmission limitations
that have been set under any of the four limit types. The Clear button will clear the settings for the Limit Type selected.
NOTE: Setting a transmission window by itself is not sufficient to start a transmission. You still need to set a start
criteria within the window.
