Claim:
A method of selecting a storage pool configuration comprising: determining a set of one or more candidate storage pool configurations; performing, for each of the candidate storage pool configurations of the set, a reliability calculation to determine a reliability value indicating reliability of said each candidate storage pool configuration; performing, for each of the candidate storage pool configurations of the set, an availability calculation to determine an availability value indicating availability of said each candidate storage pool configuration; and selecting, in accordance with selection criteria, one of the candidate storage pool configurations of the set for a first storage pool, said selection criteria including said availability value and said reliability value for each of said plurality of candidate storage pool configurations, and wherein said selecting further comprises: determining that said reliability value for said one candidate storage pool configuration represents a level of storage pool reliability that is greater than an acceptable reliability threshold; and determining that said availability value for said one candidate storage pool configuration represents a level of storage pool availability that is greater than an acceptable availability threshold.
