Summary
This chapter discussed how the commoditization of storage hardware and the poor utilization rates endemic to DAS environments lead to poor storage yield, a correspondingly high COPQ, and an increased TCO for storage. Storage networks provide strategic advantages by lowering IT costs and by eliminating the waste associated with poor storage utilization. Storage networks also address vulnerabilities by increasing data availability.
In the following chapter, I outline how the tangible and intangible benefits of networked storage, primarily increased utilization and increased availability, can lead to a reduction in the TCO for storage.
