Thread: dual-phy (copper & fiber) NIC?




dual-phy (copper & fiber) NIC?

Sorry for the slightly OT, but I've run out of ideas...

I could of sworn about a month ago or so, I found a gigabit
NIC (PCI
Express I think) which offered two copper AND two SFP
connectors for
fiber.   The card had only two ethernet controllers (Marvell
I think),
hence you could only use up to two connectors at any time. 
Very
similuar to many switches which give you the choice of
copper or fiber
but not both (sometimes called "combo ports").

Anyways, I didn't bookmark the page, I can't find it again
via google
and I don't remember the name of the mfg of the NIC.  Anyone
have any
idea of what I'm talking about?  Any hints or pointers to
the page,
vendor or reseller would be greatly appreciated.

Thanks,
Aaron

Syskonnect used to make these.  Marvell bought them for
their Ethernet
controller design which is the core of the current Marvell
chips.  They
may still sell high-end adapters under the Syskonnect
brand.

The older Syskonnect adapters ran as "one interface
with two PHYs" if
you used Syskonnect's Windows drivers but were actually two
complete
interfaces and with the BSD driver it was possible to use
both at once.
