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.

An enzyme inducer is a type of drug that increases the metabolic activity of an enzyme either by binding to the enzyme and activating it, or by increasing the expression of the gene coding for the enzyme.Classic examples: barbiturates (phenobarbitone), antiepileptics and rifampin.arbamazepine is another enzyme inducer. By enzyme induction it can reduce efficacy of haloperidol and oral contraceptives. The majority of enzymes which are of industrial interest are inducible. Induced enzymes are synthesized only in response to the presence in the environment of an inducer.
