Can Capacity Planning and Finance Co-exist?
Project and Program: SHARE-wide Events
, SHARE in Anaheim 2014
There is a never-ending conflict in datacenters all over the world: Capacity Planning says what you need and Finance says what you get. The key is to find that middle ground. If capacity is too low, service will be poor and business will suffer. If capacity is too high, the resulting costs cause the business to suffer as well.Hardware costs are fairly straightforward, it is the monthly software costs (MLC) that can be significant. IBM provides options to pay only for what you use via sub-capacity pricing. Many shops have avoided this option however as this requires a "cap" to be set and enforced, potentially constraining important workloads.What is needed is a methodology to track the ongoing utilization of the systems and gradually reduce the resource consumption of selected (low priority) workloads so that you can get close to the cap but not hit it and suffer delays in service. Could Capacity and Finance co-exist? Could there actually be peace and harmony? Come listen and judge for yourself.-Martin Wills-MVS Solutions, Inc.
