The largest MF shop I have worked for supported 10 sysplex, 44 lpars, at least 20 processors, across 3 continents.
The support staff was (as best I can recall) z/OS and program products including most vendor software (9), CICS/VTAM/TCPIP (6), IMS/DB2/MQ (sysprog only) (5) DBA's and other were under another manager.
