NAS and NAS Virtualization

Users' Perspectives and Plans

2007 Market Study

 

 Today, sites with tens and even hundreds of NAS are common. Managing tens or hundreds of discrete file systems dealing with additions, changes and migrations has proven be an impossible task. By creating a single logical view across multiple NAS systems, NAS virtualization (or aggregation) addresses the scaling, performance, and management problems that plague NAS scalability today.

The primary objective of this study is to determine the acceptance of the various virtualization techniques, as well as user requirements and complaints. The analysis also provides valuable answers to questions such as:

 

Survey Methodology

To qualify for the survey, the respondent had to be an IT administrator or manager with storage related responsibilities and one terabyte of total disk capacity most of which connected to open systems.

· We developed a questionnaire in collaboration with a number of industry executives
· We tested the questionnaire in interviews with industry experts and storage vendors
· We asked several thousands IT managers a limited set of questions to determine if they qualified for the survey. 
· We select about 200 of these screening survey respondents to complete the full survey. We targeted 70% of the population in the small and medium business category with the full survey respondents having mostly open systems and at least 2 SAN or NAS.
· We send a detailed questionnaire of over 60 questions to the selected respondents
· We target a minimum of 100 good responses. We compile and analyze the results, and compare with results obtained in our 2003, 2004 and 2005 surveys
· We also include comments resulting from the many contacts we have throughout the year with IT managers.
