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 relatively 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.

Medium
Recovery Policy After the remote replication internal I/O error is
rectified or the replication link is up, the
consistency group automatically synchronizes
data or not. The values include:
l Manual: The consistency group enters the
To be recovered state. You need to manually
synchronize the data from the primary
resource to the secondary resource.
l Automatic: The consistency group enters the
Synchronizing state. The system will
automatically synchronize the data from the
primary resource to the secondary resource.
[Example]
Automatic
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 when Replication Mode
is set to Asynchronous.
[Example]
No compression
