In the two most recent shops I've worked in (prior to my current gig), the Windows and Unix support staff was two times more than the mainframe staff. Operations, help desk, security worked with all groups combined. We had 7 sysprogs, 16 Windows admins, and 14 Unix admins (sysprog staff maintained Linux Redhat as part of the zLinux support, and we were quite good at Linux admin). In addition, we had 8 network engineers working on nothing but network servers. I am talking about support staff. Each area had their own development staff. The mainframe development staff was probably larger than the Windows and Unix development staffs, but probably no more than 20%. And this was a LARGE shop I'm describing. 23 million CICS transactions a day (in sub-second internal response times) against a mountain of Db2 data. The physical data center issues were no longer where were we going to put a mainframe but rather where are we going to put the next DASD array.
