Source ETERNUS CS800 List
The Source System list displays the following information for each source ETERNUS
CS800:
Source The IP address of the source system that is allowed to send data to the
ETERNUS CS800.
Actual
Data
Received
The amount of data actually received over the network during replication or
failback.
Average
Receive
Rate
The average receive rate (in MB/s) of data received over the network during
replication or failback (Actual Data Received divided by the amount of time
required to complete replication or failback).
You can customize the appearance of the Source System list in the following ways:
l Click the top banner row of the list to collapse or expand the list.
l Click the arrow to the right of a column heading and select Sort Ascending or Sort
Descending to sort the rows in the table by that column.
l To show or hide a column, click the arrow to the right of a column heading, and then click
Columns. Select the check box to show a column, or clear the check box to hide a
column.
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
l For more information about working with received snapshots, see "Receive NAS" on
page 381.
l 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 421).
