While other elements of data center infrastructure, such as networking and compute, have evolved to a point where the latest innovations solve many of the management issues inherent with large-scale deployment, common problems wrought by storage systems still remain.
For example, flash has established itself as the fastest, most expensive tier in the data center. With every major vendor pitching a flash vision, it’s not surprising it's seen as the answer to most data storage problems.
