6. Schedule a transmission window to establish 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. Select the
Window option in the Limit Type box.
Define a window to control Storage Mirroring transmissions by enabling the feature and then
specifying both window options.
 Enable Transmission Window—This option specifies whether a transmission window is in
use.
 Open window time—Specifies the time, formatted for AM or PM, when the transmission
window will open, allowing transmission to begin.
 Close window time—Specifies the time, formatted for AM or PM, when the transmission
window will close, stopping all transmission.
7. Click OK to save the settings.
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.
