Sample Applications

The Ethernet Connection Blade is designed to consolidate your network core providing high-bandwidth
connections between the server chassis and workgroup switches. Some typical applications are
described in this section.
3.2.1

Backbone Connection

The switch can connect to the network backbone or other key sites over high-speed gigabit Ethernet
links, increasing overall bandwidth and throughput.
In the figure below, the uplink ports are providing 2 Gbps full-duplex connectivity to the corporate
backbone, to the Internet, and to other servers.

Making VLAN Connections

The switch supports Virtual LANs (VLANs) which can be used to organize any group of network nodes
into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can
eliminate broadcast storms in large networks. This provides a more secure and cleaner network
environment.
VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN
group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch.
However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the
inter-switch links.
