Dear Friends,
I am looking to scope out a possible conversion from ESCON to FICON on a
Shark I manage. There are currently 4 ESCON channels EMIFed to 4 LPARs
on one CPU. If this were to converted to FICON channels, approximately
how many would I need? With only one CPU in the complex, can I connect
the channels natively or shoulr I look at a FICON director. I don't
currently use an ESCON director.
Use 2 FICON channels. Single FICON is usually equivalent of 7-8 ESCON
channels, so the second FICON is just for redundancy.
You don't need director.
I am having some troubles finding documentation which addresses the
above questions. Could someone please send me a URL or some
recommendations on how to scope out this conversion.
Try www.redbooks.ibm.com and search keyword FICON.
Something like "FICON Implementation" should appear.
Pay attention to FICON features on both sides. It should be LX (long
wave). When you have mix, i.e. LX on CPC side and SX on Shark side, then
you cannot connect it directly. Use Single Mode (yellow) cables.
