 Even as IT organizations face significant budget pressure, business carries on and continues to drive storage growth. So, how can IT organizations meet organizational needs without buying more storage? Let’s do a little math.

First, two baseline numbers are important. Industry analysts peg average storage utilization at 35% and the compound annual growth rate (CAGR) for storage at 50%. We can now apply these two numbers whatever assumption we wish. To make the calculation easy, assume that we have a total capacity of 100 TB with a 35% utilization (35 TB). With a 50% CAGR, we would utilize 52.5 TB (52.5%) and the end of 12 months and 78.75 TB (78.75%) after 24 months. Thus, the “average” organization can survive up to two years without buying another byte of storage, if only they can find a way to utilize what they have. If you know your utilization and CAGR, you can easily apply this calculation yourself to see how long you can survive without buying more capacity.

Not sure what your utilization or CAGR is? That’s where SRM tools like CommandCentral Storage come in. Remember the old adage, “If you can’t measure it, then you can’t manage it.”
