Administrator Guide

Refer to the
Dell DR Series System Interoperability Guide for details about the supported system limits for replication
per DR Series system model. For a definition of connections and streams, see
Streams_vs_Connections.
• Version Checking
— The DR Series system software includes version checking that limits replication only between
other DR Series systems that run the same system software release version. If versions are incompatible, the
administrator will be notified by an event, and replication will not continue.
• Storage Capacity and Number of Source Systems — Be aware that the storage capacity of the target DR Series
system is directly affected by the number of source systems writing to its containers, and also by the amount being
written by each of these source systems.
• VTL Replication — Replication of VTL containers is currently not supported; however, it is planned for a future
release of the DR Series system.
• MTU Setting
— Primary and secondary replication targets should have the same network maximum transmission
unit (MTU) setting. See the topic, “Configuring Network Settings,” for more information about this setting.
Creating Replication Relationships
To create a new replication relationship, complete the following steps.
1. Select Storage → Replication.
2. Click
Create in the options bar.
The Create Replication page is displayed.
3. Under
Source Container, define the source container by doing the following.
a. Click
Select container from local system or Select container from remote system, and select a container. (For a
remote system, you will need to provide user credentials for the remote system.)
b. Under
Source Container > Replica Container, for Encryption, select one of the following encryption options:
None, 128–bit, or 256–bit.
c. For
Bandwidth Speed Rate, select the bandwidth as Default or specify a rate.
NOTE: Bandwidth is the replication bandwidth limit that you can set as Kibibytes per second (KiBps),
Mebibytes per second (MiBps), Gibibytes per second (GiBps), or as an unlimited bandwidth (default). The
minimum allowed replication bandwidth that you can set is 192 KiBps.
4. Under
Replica Container, define the target replica container by doing the following.
a. Click
Select container from remote system and then select a container for the replication from the remote
system.
b. Enter the user logon credentials of the remote system.
c. Click the Retrieve Remote Container button and, in the drop-down list, select a remote container from the list of
available containers.
5. To set up cascaded replication (optional), define the cascaded replication by doing the following.
a. Under
Cascaded Replica Container, click Select a container from the remote system to select the container you
will be using for the cascaded replica.
b. Enter the logon credentials of the remote system.
c. Click the
Retrieve Remote Container button, and, in the drop-down list, select a remote container from the list of
available containers.
d. Under Replica > Cascaded Replica Container, for Encryption, select one of the following encryption options:
None
, 128–bit, or 256–bit.
e. For
Bandwidth, select the Bandwidth Speed Rate as Default or specify a rate.
6. Click the
Create Replication button.
Modifying Replication Relationships
You can modify the following replication settings: bandwidth, encryption, and remote container’s IP address/host name
settings. To modify settings for an existing replication relationship, complete the following steps.
