replication data to the target system.
If encryption is enabled, select an encryption strength (
128-bit or 256-bit ). Using
256-bit encryption (default) provides a stronger level of security but may have an
impact on system performance in some situations.
V
CAUTION!
Select 128-bit encryption if you are sending data to a ETERNUS CS800
running a system software version prior to 2.1.1 Software.
I
For best performance, if your data network is already secured, you should
clear the
Encrypt data before replication check box.
c) In the Source IP Address field, enter the IP address that is used to uniquely identify
the source ETERNUS CS800 to the target. This may be different than the actual
network IP address of the source ETERNUS CS800.
If the target system is at 2.1.1 Software or higher, this field is not required.
Otherwise you must enter the IP address by which the target system recognizes the
source system. The default value is
0.0.0.0 .
2. If data on other systems will be replicated to this ETERNUS CS800, enter the following
information under Source System :
a) In the Source Hostnames or IP Addresses box, enter the hostname or IP address
of the system that will send the replicated data to the ETERNUS CS800.
To enter multiple sources, press <Enter> after each entry. You can specify up to 10
replication sources.
b) In the Maximum Snapshots Per Share or Partition drop-down box, select the
number of snapshots to retain for each replicated share or partition (up to 32).
During scheduled or manual data replication, the ETERNUS CS800 receives a
snapshot from the source system. A snapshot contains all of the data necessary to
fully recover or failback a NAS share or VTL partition to the point in time when the
snapshot was saved.
