Features provided by
dpnnetutil
Running
dpnnetutil
provides the following features:
Single-node Gen4S systems
For single-node systems, the feature set includes:
l
Detection of cabling and connectivity errors during configuration, including:
n
No link detected on a network interface
n
Link speed below 1GB
n
Auto negotiation
n
Full duplex
When an error is detected, a dialog box is displayed that describes the error and the
network interfaces affected.
l
Determination of the cabling schema based on the number of physical network
interfaces and link presence.
l
Configuration of the backup, replication, and management networks, including:
n
Requesting IP addresses and netmask for replication and management networks
n
Allowing edit and confirmation later
Note
Remember, if all backup, replication, and management interfaces are configured for
use on the single node server, they must be configured for different subnets.
l
Configuration of backup VLAN interfaces, including:
n
Requesting a list of VLAN IDs available on the customer network switch
n
Requesting corresponding parameters for each VLAN ID (IP, netmask)
The customer network administrator must provide a list of correct VLAN IDs (typically
in the range 1 to 4094). The site networking topology must be such that all clients are
able to resolve the Avamar server by the same hostname from different VLANs.
Otherwise, backup failures may occur.
The
dpnnetutil
utility populates
probe.xml
with information obtained during the
configuration procedure.
Replication
The following sections describe the types of replication architectures supported by ADS
systems. For complete instructions on setting up and performing replication, including
terms and concepts, capabilities and limitations, and best practices, see the
EMC Avamar
Administration Guide
.
Single-node servers
The networking architecture of ADS Gen4S and the Avamar software provide two types of
replication: Basic and Dedicated. They are described in the following sections.
Basic replication
The source and target systems each have a single network for traffic of all purposes.
Replication is in and out on this single network between the source and target pair. The
