information associated with any files in your replication set can be
transmitted to the target.
● Maximum Pending Mirror Operations—This option is the maximum
number of mirror operations that are queued on the source. The default
setting is 1000. If, during mirroring, the mirror queued statistic regularly
shows low numbers, for example, less than 50, this value can be increased
to allow Storage Mirroring Recover to queue more data for transfer.
● Size of Mirror Packets—This option determines the size of the mirror
packets that Storage Mirroring Recover transmits. The default setting is
65536 bytes. You may want to consider increasing this value in a high
latency environment (greater than 100 ms response times).
● Block Checksum All Files on a Difference Mirror—This option allows a
filedifference mirror to check each block of data, regardless of the file
attributes. If this option is not marked, Storage Mirroring Recover will assume
files are synchronized if their attributes match.
Note:
Database applications may update files without changing the date,
time, or file size. Therefore, if you are using database applications,
you should use the Block Checksum All Files on a Difference
Mirror option to ensure proper file comparisons.
If you are not using database applications, disabling this option will
shorten mirror times.
