When Something Is Simple It Must Be Simple To Prove
Provisioning high-performance storage has always been a chore. Care and concern over spindle count, RAID type, RAID attributes, number of controller arms involved and a long list of other complexities have burdened storage administrators. Some of these troubles were mitigated by the advent of Automatic Storage Management–but not entirely.
Wouldn’t it be nice if the complexity of storage provisioning could be boiled down to but a single factor? Wouldn’t it be nice if that single factor was, simply, capacity? With EMC XtremIO the only factor storage administrators need to bear in mind when provisioning storage is, indeed, capacity.
