If you are like me, you would feel misinformed. This article does not talk about soda but about the consumption of mainframe MIPS (millions of instructions per second) required to move data around the enterprise. Practically every IT budget places a priority on how many Mainframe MIPS are being consumed. If there’s a disconnect, between what is planned for and what is used, then enterprises may find themselves with unanticipated costs.

According to The Hidden Cost of TCP/IP on Z/OS, a White Paper prepared by Bill Yeager, Chief Technical Officer at Alebra Technologies, many mainframe systems use TCP/IP to move data to and from the Mainframe. In addition, he states that it is natural to expect that as the volume of transfers increases so will the expenses of using the resulting processors. However, what did surprise Mr. Yeager was that customers had indicated to him that the system usage reported under their job accounting did not match what they were seeing as far resource consumption.

He set out to see if he could explain this phenomenon, so he set up benchmark runs using standalone processor environments with no other workloads present. What he found is the job accounting for the FTP clients captured only 50% of what was being consumed. He believes that the differential is significant enough that either or both of the following should be considered:

􀂃 A charge-back system should be put in place to account for this time.
􀂃 Alternative methods should be considered
