My current employer does in one data center; my immediately previous work experience was to move another customer from z/OS to AIX for TSM. I'm not a MVS guy, so my list of "pros" for this is short: a) a shop already has z/OS b) z/OS is where they have tape drives and where they already know how to handle tapes. The list of cons is barely longer: a) There is no TSM version 6 for z/OS, so clearly that's not a good long-term direction. This is probably a response to lack of customer demand. b) Lots of z/OS software is (used to be?) priced by total CPU power in use by z/OS. Running TSM on z/OS means you require more z/OS capacity, driving up those your software costs. c) If you're used to running TSM on other platforms, having something else act as your library manager may feel abnormal. Apart from those pros and cons, the experiences are probably a result of whether you've got z/OS guys who are also trying to run TSM, if if you have TSM administrators who are trying to run TSM like they would on any other platform. Issues like "what automates responses?" will depend on whether you try to use z/OS native facilities or the same tools an AIX TSM site would use. Oddly enough, when I saw the subject line, I figured it'd be a question about running TSM on Linux on z/Series. That can run on IFLs, and that doesn't factor into your z/OS software costs, because that's not z/OS capacity. What are the contending platforms? How disciplined and experienced are you on those platforms? Many of us love AIX as a host platform for TSM, but if you don't have any AIX experience, the learning curve there may deter you. Others run TSM on Windows, although there are those who cringe at putting major services on a Windows server, perhaps related to bad experiences with Windows as a workstation, or bad experiences with Windows administrators who don't understand why servers are different from workstations.
