It is not a linear function on System z.
Scalability is part of the value proposition for the platform not just
for the machines but people's ability to manage them.
That is not just marketing from IBM. We have doubled MIPS with
negligible staff growth for the platform. The sticky part is that is
that it takes a certain critical mass to support 24x7x365 operation of
z/OS + transaction subsystems + middleware. Once you have that core
staffing level you can run nn more LPARS with nnnnn more MIPS without
any additional systems programming staff.

Subject: Number of Sysprogs & sysadmins per 100 MIPS
Dear List
I am in search of information on typically how many system programmers
and system administrators would be required, on an average, to support
say 100 MIPS. It is not that I am specifically looking at 100 MIPS
installation, but rather I want to extrapolate this number (if possible
linearly) to estimate the number of sysprogs and sysadmins required to
support a site of any size - say X MIPS. I know the number of sysprogs
and sysadmins at different sites varies even when comparing sites of the
same size. Nevertheless I am looking for a rough ballpark number.
I also understand this number is a function of the subsystems installed
at a site. For e.g. x number of DB2 sysprogs & x' sysadmins + y number
of IMS sysprogs & y' sysadmins + z number of CICS sysprogs & z'
sysadmins etc.
So what I am after is - on an average how many sysprogs + sysadmins
(z/OS, DB2, CICS and IMS) are typically required to support on an
average say 100 MIPS?
Thank you in advance.
Nagaraj
