Re: Number of Sysprogs sysadmins per 100 MIPS
In my experience (not that I'm much more than a tourist), I've seen staffing levels more as a function of how many systems, subsystems, etc., and how disparate they are. More z/OS LPARs does not necessarily mean more z/OS SysProgs, if the images are tied together in a Sysplex, or at least common enough to make software rollouts somewhat textbook. More variation means more time to handle each system, which eventually adds up to more staff (unless you're OK with high turnover). Same goes for DB2, IMS, CICS, etc. Benchmarks provided by Gartner and the like, don't tell the whole story, because every shop and workload is unique.

Re: Number of Sysprogs sysadmins per 100 MIPS
Just to echo the previous responses, Gartner has some data on staffing levels, and you may wish to check with them. To summarize, they see much the same thing: for mainframes there's a (more or less) fixed operational staffing level and then zero (or very near it) operational staffing as you add workload. That is probably unique in computing and keeps getting more important as general service sector wages and benefits increase relative to materials and goods, and as IT activities become a larger share of total business activities. (That's a long-term, secular, global cost trend, although different countries are at different points on that trend.) Also, there have been impressive operational productivity improvements over the past several years owing to many factors, including increased automation. Those productivity improvements seem to be fully compensating for the capacity increases -- maybe even more than fully. Anyway, that's my summary. Your situation may be different. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: [EMAIL PROTECTED] -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

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?

Re: Number of Sysprogs sysadmins per 100 MIPS
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 n more MIPS without any additional systems programming staff.

Re: Number of Sysprogs sysadmins per 100 MIPS
Such typical value per 100MIPS has no value at all. Over years we have grown almost 100 times (in MIPS terms) with no staff growth. -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.
