Parameters of remote replication
Parameter
Description
Value
Speed
Speed of data synchronization. The values
include:
–
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.
–
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.
–
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.
–
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
Recovery Policy
After the remote replication internal I/O
error is rectified or the replication link is
up, the remote replication pair
automatically synchronizes data or not.
The values include:
–
Manual
: The pair enters the
To be
recovered
state. You need to manually
synchronize the data from the primary
resource to the secondary resource in
the pair.
–
Automatic
: The pair enters the
Synchronizing
state. The system will
automatically synchronize the data
from the primary resource to the
secondary resource in the pair.
[Default value]
Automatic
