Parameter Description Setting
Speed Rate of data synchronization of the
consistency group. The values include:
l Low: When the speed is set to low,
remote replication will take a long time.
This value is applicable to scenarios
where the service load is heavy. The
speed is normally from 0 to 5 MB/s.
l Medium: When the speed is set to
medium, remote replication will take
relatively short period. This value is
applicable to scenarios where the
service load is heavy. The speed is
normally from 10 to 20 MB/s.
l High: When the speed is set to high,
remote replication will take a short
period. This value is applicable to
scenarios where the service load is
relatively light. The speed is normally
from 50 to 70 MB/s.
l Highest: When the speed is set to
highest, remote replication will be
complete in the shortest period. This
value is applicable to scenarios where
the service load is light. The speed is
normally above 100 MB/s.
[Default value]
Medium
Data Transmission During data synchronization for the
consistency group, data is compressed or
not. If you select data compression
transmission, replication links are with
lower bandwidth pressure, while improving
the replication performance. The values
include:
l Compression
l No compression
NOTE
This parameter is available only when
Replication Mode is set to Asynchronous.
[Default value]
No compression
