General
Recommendations
When considering the use of network segmentation, refer to the following general
recommendations:
Avoid Segmentation Where Possible
Segmentation options are provided for use in environments where it is required to
separate management, data, and replication traffic, but in most cases this is not
necessary and simply introduces unneeded configuration complexity.
Avoid LACP
While the use of LACP (Link Aggregation Control Protocol) to manage the allocation of
traffic across bonded DXi ports is supported as an advanced configuration option, its
use is discouraged. LACP configuration can be complex, and improper configuration can
render your system inaccessible. Also, the router must be configured for LACP before
enabling LACP on the DXi.
Use Round Robin
Where possible, use of balanced Round Robin (Mode zero) bonds is preferred for
simplicity. Round Robin refers to the method used by the DXi system to balance
outbound data transmission. It has no effect on data reception inbound to the DXi
system. Inbound traffic is controlled by the load balancing algorithm within the
upstream Ethernet switch. Based on the switch algorithm in use, traffic observed
inbound to the DXi system may or may not appear balanced. This is normal.

The following network segmentation recommendations are listed in order of
complexity:

Basic Network Recommendations
•
Intermediate Network Recommendations
•
Advanced Network Recommendations
Basic Network Recommendations
Basic network configurations do not include network segmentation, do not require
switch re-configuration, and conform to the
General Recommendations
on page 6. No
Segmentation means that data, replication, and management traffic may use the same
network. If your network policies require separation of replication or management
traffic, continue to the
Advanced Network Recommendations
on page 8.
DXi6700 (2 x 1 GbE Ports) and DXi6701 (6 x 1 GbE Ports)
If less than 1 Gb per second (~450 GB/hr) of performance is required, follow these
steps. Otherwise proceed to the
Intermediate Network Recommendations
on page 7.
