The cost model - TCO - I use at our company up to this point has always been compared to another platform, whether it is a refresh or new business ( x86, pSeries, Iseries, Sun or HP). I factor in cost for each server, staffing to support ( this case I only show the difference in the build and run maintain staffing - since sysadmin at the middleware level remains constant and the plus is that there is no need to retrain), floor space and electrical power needed to run. On the electrical power grid is where the system z shines, since you can (theoretically) get 3200 servers in one footprint for no more the 5 KW and if you compare this to an x86 virtualization approach using our data center numbers consumes 122KW. The only additional charge is the hipervisor costs and kernel OS. I do not include cooling as a cost but show the advanced system z technique of internal liquid cooling (much like your car) versus ambient which is the warmer the room the hotter the servers runs thus the AC must run stronger and that is hard to get a true factor for.
The other factors such as middleware software costs, future server deployment techniques, kernel and midleware software maintenance savings are presented in slides to highlight the benefit with system z and then a custom TCO is built for each issue. For instance, SAP in most cases is based by the number of users, however, on any other platform except the system z Oracle is available for SAP. So then I highlight the incentives that both SAP and IBM provide to use DB2 on z/OS. Oracle pricing on its own is, for instance z10 4 core processor,t 47K each core = 188K. However, if you add another IFL to the LPAR you are only charged 75% of that cost. As is obvious by now middleware is a fluent cost - especially with the ISVs. IBMs goes by value units which makes it easiet to customize and compare. Another factor to include is the Network and the cost reduction in staffing, hardware, floor space, cooling, points of intrusion and failures versus z/VMs capabilities. Security could be included here by taking the encryption and decryption out of the network decreasing bandwidth and hardware and using the built in crypto feature of the system z. Finally I map this out for 5 years - of course the more the initial server deployment the better the ROI. However, if you plan to add servers to this platform farm you can show additional ROIs based on no hardware additions, only an IFL or IFL and memory. Actually any combination there of but one thing for certain it WILL provide a faster ROI then any platform. My average calculations have it against our x86 virtualization concept of 1000 servers 13 months down to 40 servers 28 months. BUt if I add 40 servers to an existing CEC with no additional hardware its 10 months. This makes the user happy and actually makes the CIO happy since it cost us virtually nothing to put in place.
