Twenty-four percent of respondents indicate they plan to decrease their spending for tape systems in 2007, a fairly hefty increase over the 18% reported last fall (see graph 5, "Tape feeling brunt of disk-based backup as companies cut back on spending," at right). Perhaps even more telling is that only 33% say they'll increase tape spending vs. 47% in our previous survey. The jury is still out on tape's demise or at least its diminished role until further surveys can establish this spending pattern as a trend.
But there's further evidence that the love affair with tape may be waning. For those respondents who plan to purchase tape libraries in 2007, the average number of slots indicated is 130 vs. the 159 reported a year ago, a drop of approximately 18%. Higher capacity media certainly contributes to the lower slot count, but less reliance on tape is another apparent factor.
Although Independence Blue Cross added one tape library last year and one this year, it's building out its virtual tape environment. "I don't think we're going to be adding any more tape," says the firm's Boyer. "If anything, we'll probably add more space in the virtual tape space as we deploy that out to more and more apps."
Increasing interest in two key disk-based backup technologies--data deduplication and continuous data protection (CDP)--are also bolstering the shift away from tape. A little fewer than 10% of respondents say they're using CDP, while almost 8% have deployed some form of data deduplication. Modest numbers, perhaps, but they double the percentages reported in the previous survey. And plans for 2007 deployment of these technologies register even higher: 16% for CDP and 12% for data deduplication.
Storage managers may have cast a wary eye toward CDP and data deduplication in the past, but appear to be warming up to--if not embracing--them now. Twenty-nine percent of respondents say they plan to increase spending for CDP, while 31% say the same for data deduplication. Perhaps storage managers, getting a bit of a breather from dealing with rampant growth, now have time to implement newer technologies to enhance their management of installed storage.
"I would love to get rid of tape," says Kirsteins at Temple University Health System, "but hospitals and healthcare in general are hoarders; they hoard all their data." Kirsteins' group is planning to add another tape library to handle the retention of voluminous healthcare data. "We have to keep it long term and we'll probably never use it; to back up that data and keep it offsite on disk is crazy," says Kirsteins.
Slimmer switch vendor field
As expected, Brocade Communications Systems Inc.'s acquisition of rival switch maker McData Corp. gave Brocade the boost it needed to regain the top spot from Cisco Systems Inc. Cisco had closed the gap between the two companies over the past couple of years, but this time Brocade slipped past Cisco with 44% of respondents citing it as their primary switch vendor vs. 40% for Cisco. What's surprising is that Cisco seems to have benefited from the acquisition as well, perhaps because users with both Cisco and McData switches have decided to standardize on Cisco for future purchases.
Boyer isn't concerned about the merger. "We've gone through the Brocade user meetings and heard everything they had to say when the merger went through," he says, "and I don't think it's really going to affect us."
Seasonal shifts
Because Storage conducts its purchasing survey twice a year, we're able to see short-term shifts in buying patterns as well as longer term trends. We'll see if the second 2007 purchasing survey confirms this spring's changes. For now, it looks like spiraling storage capacities might be easing a bit, giving storage managers a chance to evaluate some newer management tools, although continued caution is likely. "We're a manufacturing company so we're not going to get all bleeding-edge anything," says Visher at The Timken Co. "We try to wait for things to settle down a little bit." And Visher is also girding for another round of capacity increases. "Maybe it won't be 100[TB], but I'm sure it will be another 50[TB] at least."

ABOUT THE SURVEY: Storage magazine's Storage Purchasing Intentions Survey is conducted twice a year (in the spring and in the fall). Storage subscribers are contacted by email and invited to participate in the survey. For this edition, we had a total of 680 respondents. Respondents are asked if they have purchasing authority in four areas: disk subsystems (643 respondents), storage networking (506), backup and disaster recovery (471), and storage management (407). Thanks to everyone who participated in the survey. |
