for loss of data. To avoid using the entire queue, you can configure Storage
Mirroring Recover to begin transmitting data to the target when the queue
reaches a certain point. This point can be defined as a percentage of the disk
queue that must be in use or the number of bytes in the disk queue. For
example, if you specify 40%, when 40% of the queue is in use, Storage
Mirroring Recover initiates the transmission process and sends the data in
the queue to the target machine. The transmission stops when the queue is
empty or a Storage Mirroring Recover stop transmission criteria is met. Or
you might set a queue threshold of 500 MB. Storage Mirroring Recover will
wait until there is 500 MB of data in the queue and then begin transmitting the
data. Like other start criteria, Storage Mirroring Recover continues
transmitting until the queue is empty or a Storage Mirroring Recover stop
criteria is met. Specify a percentage of the disk queue and system memory
that must be in use to initiate the transmission process, and/or specify the
number of bytes that must be in the source queue and system memory to
initiate the transmission process.
Note:
A Transmission Session Start setting will override any other start
criteria. For example, if you set the Transmission Session Start and the
Queue Threshold, transmission will not start until you reach the indicated
start time.
5. Schedule any desired stop criteria to stop transmission after a transmission start
criteria has initiated the transmission. If you do not establish a stop criteria,
transmission will end when the queue is empty. Select the Stop option in the Limit
Type box.
Define the stop options to stop Storage Mirroring Recover transmissions by using
either or both of the following options.
