Through this point in IP Storage Networking — Straight to the Core, the topics primarily covered provide an explanatory approach to storage networking with a focus on IP-oriented solutions. In the following three chapters, we delve deeper into deployment scenarios that combine traditional SAN concepts with non-traditional models for new storage platforms. Those non-traditional models involve both network shifts and intelligence shifts.
On the infrastructure side, the storage industry is witnessing a rapid commoditization of components. It seems like just about any storage related problem can be tackled with one or more servers with specialized software. While these products and solutions might not solve all enterprise needs immediately, keeping a close eye on the progress of general purpose products offers flexibility and options for IT professionals. Meanwhile, the network build-out for storage solutions offers location choice for storage services. Coupled with the migration to open systems platforms and Ethernet and IP networks, product consolidation opportunities and costs savings arise.
While IT professionals can reap savings from IP Storage network deployments such as SAN extension, storage consolidation, and service provider SANs, there are added benefits to leveraging an IP storage network model in non-traditional applications.
Chapter 8 includes two specific examples around fixed content, email and images, and how customers used storage configurations that exploited IP and Ethernet infrastructure in conjunction with distributed services to maximize operational efficiency.
