Parameter Description
Transmission Bandwidth
The parameter indicates the
data transmission
bandwidth.
To specify a data
transmission bandwith, you
should confirm that the
entered value is larger than
100.
Bandwidth for data
transmission.
Synchronous Method
None, Differently
Synchronization,
Automatically
Synchronization, or Fully
synchronization
Data synchronization method.
The value of this parameter
can be:
l
None
: Replication is
directly started without
synchronization. You can
select this value if you can
ensure the consistency
between the data volume of
the production center and
that of the disaster recovery
center.
l
Differently
Synchronization
: The
system finds the difference
between the data volume of
the production center and
that of the disaster recovery
center, and copy the
difference to the disaster
recovery center. The CPU
occupation of this method
is quite high.
l
Automatically
Synchronization
: The
DCM mechanism is
adopted in this method.
This method features high
replication speed and
supports resumable
multithread downloading.
This method is
recommended.
l
Fully synchronization
:
Data in the production
center is replicated to the
disaster recovery center in
order. The replication
speed is low.
