C220 w/ VIC 1225 directly connected to NAS

[Denny Trujillo]

Hello, does anyone know if I can directly connect a VIC1225 port to a 10GB port on a NAS system? I would be using a twinax cable to do so. My only concern is that since they are like devices, I could need some sort of twinax crossover cable. Could it be that either the VIC1225 or the NAS 10GB port have auto sensing capabilities to switch the send/receive pair?

Not supported.  You'll need an intermediate 10G switch.

Robert, would it work if I use optic SFPs vurses a twinax cable? I assume the reason why a twinax doesn't work is because both the NAS (NetApp)  and the server will be using the same pair to send/receive. If I use fiber, I can cross the send/receive wire.

Thanks!

Denny,

I stand corrected.  I checked with some colleauges and you should be able to directly connect your devices back to back with no cross over.  Twinax should work in this regard in addition to optics.  No need for any special crossover cabling.
