Section 5 Application / Technical Notes
one nut or bolt in the same bag unless there’s no alternative – or in real life, no
more than 2 ports in one zone.
In general, you only want two-way communication – not 3 or more way
communication. Overlapping zones are OK, as long as they are thought out.
As switch connections increase, it may be necessary to have more than one
switch – this is called cascading switches. The problem is that cascading the
switches kind of goes back to provisioning, in that you can/should only have
one cascade port in a zone – without any others (unless they are in other
zones). A certain 4GBit switch I know of has (24) 4GBit ports, but has (4)
10GBit cascade ports. You obviously won’t get the throughput of 48GBits
coming to/from the 4GBit ports going at the same speed going through the
10GBit ports, so careful planning has to be done when scaling up with
switches.
