This is not one of my strengths.
I have read all the redbooks on it.
My understanding is that TCP/IP on z will/can use FICON/ESCON (CTC) to talk to
another z.
But, it doesn't say directly, that OSA is required for other platforms.
It implies it by showing configs using that.
Never shows a FICON (ESCON) connection to the world beyond z.
I've read all I can (understanding little), and the question is:
Can I use FICON (ESCON) connections to talk to alternate platforms?
Do I want to?
Or, is OSA the way to do it?
When in doubt.
PANIC!!
I beleive that Cisco has a ESCON CIP for the 7500 series routers. So
you could use ESCON to 7500 for IP connectivity. I don't think there
are any networking devices that support FICON, as FICON is based on FCP
which is for SAN the communcation. At least it is my understanding that
FICON is based on FCP, could be FCP is based on FICON.
OSA is really the way to do it though. A OSA adapter is really just two
NIC's or LAN adapters for the mainframe. You can get gigabit fiber,
gigabit copper and even 10g fiber. I don't think you can get Token Ring
on z9's and if you can get Token Ring for z990's I think there are
limitions.
