The statistics in the Source System list are for each source ETERNUS CS800 rather
than a cumulative total for all sources as is displayed on the Home page.
Adding a Replication Source
Add a system to the list of replication sources to allow it to send replicated data to the
ETERNUS CS800. You must add a source system to the list of allowed replication sources on
the target ETERNUS CS800 before you configure the source ETERNUS CS800 to send
replicated data to the target. The ETERNUS CS800 can receive replicated data from up to
10 sources.
Additional Information

For more information about working with received snapshots, see "Receive NAS" on
page 356 .

It is typical for the target ETERNUS CS800 to require additional disk space for
replication data compared to the source ETERNUS CS800. This is because complete
replication data is sent to the target before old data is deleted. For optimal
performance, if the ETERNUS CS800 is a replication target, Fujitsu Technology Solutions
recommends keeping the amount of free space at 20% or more (see
"Disk Usage" on
page 393 ).
To add a replication source:
1. Under Source System , click Add .
The Add Allowed Source window displays (see "Add Allowed Source" on page 259 ).
Figure 180: Add Allowed Source
2. In the Source Hostname or IP box, enter the hostname or IP address of the system
that will send the replicated data to the ETERNUS CS800.
To use hostname format, you must specify at least one DNS IP address on
the
Network page (see "Network" on page 293 ).
3. Click Apply .
