Long ago I posted about this subject. Here are two. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Subject: Re: Service Def Coefficents From: Tom Marchant <[email protected]> Date: Thu, 6 May 1999 18:27:07 -0400 We no longer charge for CPU time. When we upgraded from our 360-67 to an Amdahl 470V/6, we took care that users would see the same bill for the same work. It seemed to make sense at the time. We upgraded to a V/7, V/8 and 5890-300E. Each time, we increased the CPU billing rate so users would see the same charge for the same work. We also kept the charge per DASD kilobyte the same when we upgraded from 2314 all the way to 3390. At the end, on the two engine 5890-300E, we were billing at a rate of about $50 million per CPU-year. We bought two 5890s. The first one started out as a 180E, for which we paid $1.2 million. Over time it was upgraded to a 300E. The other was a 300E purchased later on the used market for $43,000. IMHO, if you are going to charge for computing resources, your charges must be in line with your costs or you will drive away all of your customers. This kind of scheme is probably one of the reasons that some users believe that it is cheaper to run on other platforms. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Subject: Re: Chargeback under MVS/ESA From: Tom Marchant <[email protected]> Date: Fri, 1 Aug 1997 12:45:20 +0600 ... any chargeback system should be kept as simple as possible. For example, we have been trying to figure out how to handle billing for central printing of output generated from outside of MVS: UNIX, PC, etc. When I showed the announcement for a spiffy new IBM color laser printer a while back, he got really wide-eyed, but he wondered how he could get good accounting data to charge back to the non-MVS users. I told him that for that kind of output, we could just charge users by weight when they came to pick it up. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
