Businesses throughout the world are adapting IT infrastructures to an increasingly dynamic information environment, driven by growing user adoption of the Internet. The Internet revolution is causing businesses to rethink every interaction with customers, suppliers and partners. Storage is at the heart of this revolution. Storage networking is looked upon as a data access enabler, and SAN architectures are capturing CIO's attention as the prime candidates for reliable and scalable data processing.
The objective of this report is to analyze the different implementation approaches, compare products functionality, identify the major players and assess their strategic direction and their market shares. The report also forecasts the market evolution. The following are some of the questions that this report will address:
1- Market Overview · What are the trends affecting storage, and what is prompting the changes? · How are Application Service Providers (ASP) affecting the storage industry? · How has SAN evolved and what promises does the future hold?
2- Applications, Users · How do the users perceive SAN? What are their motivation, their complaints, their wishes? · How can SAN help implement web serving, storage utility?
3- Architecture and Technology · What are the recent technological advances in software management, in interconnecting techniques? · How does SAN compare to NAS? Are these architectures complementary or competing? · Is Fibre Channel in danger of extinction? Is FC over IP a viable solution? · Will the new protocols (iSCSI, VI, InfiniBand) help or slow SAN expansion?
4- Market Opportunities · How large is the market potential, and how will the different scenarios unfold? · What are the vendors market shares, and how can new entrants affect this distribution?
5- Market Participants and Strategic Directions · What are the major 30 vendors implementing or shipping? How are their products positioned? Who is leading the market, the technology? · Who are the candidates for partnership?
6- Products · What are the product segments, and how are products differentiated in class levels? · How do competing products compare? What trends will most likely materialize?
The report is addressed to marketing managers, planning executives, and system designers from storage system component vendors, integrators, value-added resellers and application service providers. It also addresses Managers of Information Systems and Information Technology personnel responsible for re-architecting their enterprise Storage and Data Management system. The report will also benefit investors and venture capitalists.
