SANs dominate at readers’ sites

We continually survey our readers to find out what trends, technologies, and products you’re most interested in reading about, but once a year we conduct an extensive readership survey. We recently completed our 2006 survey, and I noticed a few interesting results.

For the first time, SANs have become the dominant storage architecture at our readers’ sites (see figure). SANs were dominant at 44.7% of the sites, with NAS and DAS virtually tied at about 28% of the sites. One year ago, the split was almost exactly even among the three architectures. Of course, the penetration of SANs is very much dependent on company size, with virtually all large organizations having SANs as their dominant architecture while many small to medium-sized businesses (SMBs) have yet to take the plunge. Our survey covered companies of all sizes, although the majority could be considered SMBs.

It was also interesting to see that print publications remain your number-one source for information. When asked to name your two primary sources of information on storage issues, 65.3% cited print publications, followed by 43% citing storage-specific Websites (with www.infostor.com being number one, of course). Also mentioned are vendor Websites, White Papers, Webcasts, and conferences/tradeshows.

But my favorite sections of these readership surveys are the parts where we ask you what technologies you’re most interested in-and which ones are of the least interest-because that helps us determine the editorial direction of the publication. In our latest survey we asked you to rank the relative importance of 20 storage technologies-some new and some old.

For the second year in a row, disk-based backup and recovery topped the list of what our subscribers are most interested in reading more about. Closely behind D2D were disk array interfaces (particularly SATA and SAS), storage virtualization (somewhat surprisingly), and “emerging technologies.”

Rounding out the top five was continuous data protection (CDP), although we suspect that cloudy definitions surrounding CDP may have artificially elevated CDP in the rankings. For more on CDP, see “CDP: Awareness up, adoption slow,” on the cover.
