C.3 CREATING AN EFFICIENT NETWORK LAYOUT

Network layout is vital. The use of

IGMP snooping

also introduces certain constraints, so take heed:

Keep it flat. Use a basic line-cascade structure rather than a pyramid or tree arrangement (see below).

Keep the distances between the switches as short as possible.

Ensure sufficient bandwidth between switches to eliminate bottlenecks.

Where the ServSwitch iPATH manager is used to administer multiple ServSwitch Agility transceivers, ensure the ServSwitch

iPATH manager and all ServSwitch Agility units reside in the same subnet.

Do not use VGA to DVI converters, instead replace VGA video cards in older systems with suitable DVI replacements.

Converters cause ServSwitch Agility local units to massively increase data output.

Wherever possible, create a private network.

C.3.1 THE RECOMMENDED LAYOUT

The layout shown in Figure B-1 below has been found to provide the most efficient network layout for rapid throughput when
using IGMP snooping:

Figure B-1. Recommended layout for networking ServSwitch Agility units where IGMP snooping is used

Note: From firmware version 3.1, tree and hierarchical structures of network switches are also supported. The local unit now
joins its own multicast group so there is always a route from the querier to the local unit which was previously missing in earlier
firmware versions.

Use no more than two cascade levels.

Ensure high bandwidth between the two L2 switches and very high bandwidth between the top L2 and the L3. Typically 10GB

and 20GB, respectively for 48 port L2 switches.
