Survey respondents said their firms added an average of 59 TB of disk capacity to top off average installed storage at a hefty 413 TB. But do they know what’s being used?
Coping with capacity is an ongoing battle. Our respondents reported that their firms added an average of 59 TB of disk capacity this year to top off average installed storage at a hefty 413 TB. And if disk capacity wasn’t enough to keep an eye on, our group reported an average stash of 451 TB of data on tape. Keeping track of triple-digit terabytes is no easy task, but 47% make do with the tools that come with their arrays; 26% use a special point tool or storage resource management (SRM) app; and 13% rely on that old storage management mainstay, Excel. Whatever tool they use, only 22% feel they have a handle on what’s being used and what’s not, while 56% feel their estimates are within 10% or 20% of reality. Forty-six percent fight back against capacity with thin provisioning, while 72% use the best capacity management tool around: They enforce some form of data deletion.
“There isn’t a single utilization tool that we can use heterogeneously without complicated agents -- only point solutions and a lot of manual tracking.” -- Survey respondent
