We're a large high school with 8 buildings. (Cisco shop) TenGIg SM to most IDFs with some MM runs. I'd like some ideas on IDF redundancy. What is the best/standard practice here?

EtherChannel copper?
MM fiber from IDF to IDF?

Thanks,
Ron

For redundancy, all network gear should have a redundant backup and all wired connections should be link-aggregation (aka etherchannel).  You can use copper, MM, or SM.  The cabling type does not matter, in regards to network redundancy.  What does matter, is that there are redundant firewalls, redundant core switches, redundant distribution switches, etc.  All connections should use link aggregation.  And the secondary gear should be on a different power source then the primary gear, so that a power failure does not take out both the primary and secondary units.

If your buildings have access layer switches, then those switches should have link aggregation to a primary core or distribution switch.  And another link aggregated connection to a secondary distribution switch as well.  Then make sure that the primary and secondary switches are on different power circuits and/or UPS's.

See this design guide from Cisco.  If the network can be designed right, then the only single points of failure would be the access layer switches.  (and you could add additional NIC's to the PC's and connect them to multiple switches if you really need full redundancy)
