They had tried "remote 3270" terminals, but found the human factors totally unacceptable (especially compared to channel attached 3270 controlers in STL bldg). I get con'ed into doing channel extender support ... allowing channel attached controllers to be placed at offsite bldg ... with no perceptable human factors difference between offsite and inside STL. Then the hardware vendor tries to get IBM to release my support, but there are some engineers in POK playing with some serial stuff who get that vetoed (because they were afraid if it was in the market, it would make it harder to get their stuff released). In 1988, the IBM branch wants me to help LLNL standardize some stuff they are playing with, ... which quickly becomes FCS (including some stuff that I had done in 1980), initially full-duplex 1gbit, 2gbit aggregate, 200mbytes/sec The POK people finally get their stuff released in 1990 with ES/9000 as ESCON, when it is already obsolete (17mbytes/sec). Some POK engineers start playing with FCS and define a heavy weight protocol that drastically reduces the native throughput, which eventually ships as FICON. The most recent public benchmark I can find is z196 "peak I/O" which gets 2M IOPS aggregate using 104 FICON. About the same time there was a FCS announced for E5-2600 claiming over million IOPS (two such FCS getting higher throughput than 104 FICON) ... and E5-2600 blade at 500BIPS is ten times processing of max configured z196 50BIPS. -- virtualization experience starting Jan1968, online at home since Mar1970
