I think that minute-by-minute usage of main memory could be accounted for in the same manor as CPU can be done if you start with the MONITOR data instead of the ACCOUNTING data. I think the current ACCOUNTING data is insufficient for a good chargeback system. Although with today's LINUX workloads w

I have done it 3 1/2 times. The first time was in FORTRAN under VM/370 R5. Two times at this job using paid-for products (VMAccount and CA-JARS). Both were too much information for management and not enough of the right information for me. The 1/2 time was much more recent thanks to a special surve

My IBM management, 25 years ago, went by the same idea that all users should pay a fixed fee. I finally convinced them that your way, i.e. a smaller fixed fee and then incremental charges made sense. I used the analogy of a hotel. When you walk into a Holiday Inn, you know that there is some

The best model is one I heard last week at the ibm conference. One large "well known" installation charges only for prime shift, with 3 different rates based on types of service. All charges are based on resource consumption. With the usage charges and prime shift only charges, users are convi

All of our current chargeback is a fixed fee based on platform (z being t he most expensive) and diskspace and number of users, just as if it were another windows box they had to buy. If I had my way, there would be a smaller fixed fee for setup based on memory size, initial DASD and initial user

Cost accounting for Linux guest running under z/VM

2008-10-20 Thread Juarez, David T.
We are in the process of getting ready to add production Linux guest and we need to know how you are charging back the customer for running Linux under z/VM. We currently charge a fixed fee per month for small, medium and large based on the size of the individual server's memory, cpu, and networ
