Tuning Raid performance has the air of a black art to storage administrators, with the perception that it can do more harm than good. Most consider the job done once the Raid level is selected. But, it is possible to fine-tune some Raid parameters to anticipate application storage demands and improve performance.

A regulatory enzyme is an enzyme in a biochemical pathway which, through its responses to the presence of certain other biomolecules, regulates the pathway activity.This is usually done for pathways whose products may be needed in different amounts at different times, such as hormone production.egulatory enzymes are commonly the first enzyme in a multienzyme system: the product of the reaction catalyzed by the first enzyme is the substrate of the second enzyme, so the cell can control the amount of resulting product by regulating the activity of the first enzyme of the pathway.
