A majority of storage managers take a proactive approach and use efficiency tools to control disk storage capacity before it gets out of hand; get the results from our latest user survey.

Keeping track of disk storage capacity is a never-ending but necessary chore. You don't want to get caught short when your apps unexpectedly get hungry for more disk, but you don't want to waste money on spare capacity that may never be used. Many of our survey's 300-plus respondents think they have it under control: 21% tell us their capacity usage estimates are exact, while 47% say they're "pretty close." Estimating accuracy is a 50-50 toss-up for 22% and 10% fess up that they're "just guessing." The most popular tools for tracking capacity are the freebies that come with arrays (42%); but 33% have shelled out some dough for management apps and 12% still rely on good old Excel spreadsheets. But storage managers take a proactive approach and use efficiency tools to control disk storage capacity before it gets out of hand. Archivers (42%) are the most popular tools, followed by compression (37%), thin provisioning (36%) and automated tiering (30%). The average installed disk capacity is 287 TB, with only 54% actually used.
