Topic: CobraNet question

To all,

Question about CobraNet and channel capacity.

Let’s say I have several NION’s in a rack, with all the CobraNet cables connected to a top line gigabit switch.  Some reasonable distance away, I have a rack with twelve Crest Ci eight channel amps, connected to another top line gigabit switch.  Switches are connected with a single, verified, Cat 6 cable.  All CobraNet bundles are set up unicast, and the network only supports CobraNet, no other network traffic.

How many eight channel bundles will the system support, if all bundles output the NION’s and feed the Ci’s?

Thanks,

Greg

Re: CobraNet question

The gig link itself could probably handle 60 to 70 bundles w/o issue. But the issue is really how many bundles can the conductor keep track of. 60~70 is near or over the real world limit depending on what else the conductor has to do and what other non-cobranet traffic is on the net or being processed by the conductor (i.e. serial bridge, packet bridge, SNMP). It could work but may not.

Re: CobraNet question

With only 12 8 channel amps, how many bundles are you planning on? If your Nions are an XDAB cluster, it should be straight forward to use 1 bundle per amp, resulting in 12 bundles which would be no problem. I would think you would have to go off the deep end with that equipment to get the number of bundles cobraguy is talking about. If for some reason you do hit a conductor-imposed limit, you can always cook up a few VLANs and use more conductors.
