They're also useful for connecting servers to top-of-rack 10G switches. But curiously, they're currently unsupported by Cisco on the Nexus 7000 platform: http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9402/ps9512/Data_Sheet_C78-437757.html They seem to work fine in this application, however. > > I would like to connect a Procurve 5406zl which has a SFP+ port to > one > > of the 10Gbps ports on a Cisco 7600 RSP720-3CXL-10GE. > As far as I'm aware, HP are particularly crappy about vendor locking > their > transceiver ports and will refuse to drive any "third party" > transceiver.

Network World recently did a 10G switch review: http://www.networkworld.com/reviews/2010/011810-ethernet-switch-test.html One of the documents linked from the review was the vendor features questionnaire. In it, Cisco said: Nexus 5000 also provides interoperability support for non-Cisco Twinax cabling. Supported vendors include EMC, IBM, HP StorageWorks and NetApp This, and an emailed promise from an HP rep are the only inter-vendor twinax support claims I've seen to date. I'm hopeful that vendors will come to their senses on pluggables, at least for twinax cabling. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
