Conclusion
This chapter showed how the TCO for storage environments is directly related to management costs. As the purchase price for storage continues to decrease, and growth remains constant or accelerates, storage management processes will remain dependant on home-grown tools and immature software products. Until interoperability becomes a reality and storage management software matures, labor costs will increase, unless the environments are homogeneous. The Bluefin initiative, along with storage virtualization software will succeed in lowering the overhead associated with storage management.Storage-centric organizations can execute a cohesive storage vision to lower costs and increase operational efficiencies. A storage vision comprised of consolidation and virtualization initiatives (both at the storage level and at the server level) can drive change throughout IT to increase utilization of IT assets and reduce waste.As storage software products mature, a sustainable storage vision will include an ILM framework for managing information through its useful life, which, in turn, will continue to lower the TCO for storage.As the case studies in Part II indicate, few companies have fully implemented a sustainable storage vision. Most early adopters have implemented only select strategies (migration and consolidation typically), where need is most acute and impact, in terms of both ROI and operational efficiencies, is quickly felt. Migration to storage networks is the most important strategy any company can implement. Without networked storage, storage-centric management strategies (consolidation, recovery, and virtualization) will not be successful.The following case studies clearly show that implementing storage networks offers true business benefits, primarily increased utilization and increased availability, which have a measurable impact on the company's bottom line.
