A very useful method is the analytical storage planning based on measurement data. In the following example, the MS Exchange-area of a company was analyzed to determine the required supply power.
see attached picture
Fig 2: measured values allow a very precise planning of power consumption and thereby reduce purchasing costs and operating costs. Another positive effect is the safety which results from this planning. These measurements show exactly how much power is needed for an environment. If this demand is covered by the infrastructure, there is no danger of performance degradation due to an incorrectly planned infrastructure.
Here the simple interpretation of the measured values showed a power requirement of 2500 IOPS. With the in-depth analysis of the data streams´ behavior, it was detected, that from the needed 2500 IOPS more than half of the power is generated by the SVC´s caches.
