Sizing Systems

Usually the hardware provider takes on the job of actually sizing the system. The advice of the quick-sizer of the SAP system is usually sought for new installations who, when changes need to be made, uses the rule of thumb "x% more SAPs for the new release".

Sizing is a lot more accurate when based on the measurement of a system which takes actual use as a starting point. In such cases the experience of VMS identifies entirely individual needs.

In one case in point we were able to save one company from having to spend a lot of money upgrading its hardware because the application also ran with the desired performance after the release change – as VMS predicted.

In another company, we were able to demonstrate that the extent of the planned re-equipping would not be sufficient.

Finally, hardware simply can't solve all performance problems. This was confirmed to us by a client who completely doubled his hardware power in a rollout, only to find that performance had not improved. Only a targeted tuning by VMS brought the desired success.
