Dwight,

        You mentioned the OSA. Does that mean that you have had experience
using them ? We have had an OSA for some time but we had only the
Ethernet feature installed until recently. We are going to use the MVS
system as a ADSM server and we added FDDI features to the OSA so that
we could have greater throughput ie 100mbits/sec vs the 10mbits/sec
over Ethernet. Our OSA is connected to a switch, the switch supports
FDDI, 10Baset Ethernet and 100Baset Ethernet connections. We are not
getting anywhere near the the throughput we expected over 100Baset to
FDDI. We expected 3 mbytes/sec but are achieving considerably less.
If you are using the OSA, how do you have it set up ? What throughput
are you getting ? What version of TCP/IP ? Are you using Offload or
Passthrough processing ?
Any information you may have would be appreciated.
