I'm new to this list, so excuse my ignorance in asking this question which may have
already been kicked around. We are having performance problems doing backups from
several AIX boxes to an OS/390 mainframe. We've looked at the network and tons of
other things. To make a long question short, we've determined that the problem is
that an AIX box will only do 5 GByte per second ESCON channel connected - - we believe
this is the weak link in the chain, so to speak, causing our "ADSM backups take too
long" & "ADSM backups not using all the available bandwidth" problems. However, we
are getting conflicting and widely varying info on this 5 GByte/second number. Is 5
GByte/second really the max an AIX box can do ESCON channel connected to whatever? Can
anyone point me to an ADSM tuning document or whatever which addresses issues like
this?
