Symantec commissioned this survey through Applied Research in March 2009 with a total of 400 IT professional respondents from the United States with direct responsibility over their organizations' storage infrastructures and operations. The 2009 Stop Buying Storage survey highlights storage use trends and other habits related to the optimization of current storage capacity.
These are organizations that have enough storage that manual tracking is not going to cut it. Yet a full 25 percent of these organizations are either manually tracking storage (13 percent), guessing based on industry averages (5 percent), not tracking utilization (1 percent) or worse -- they are estimating how much capacity they are using (6 percent). It is probably a safe assumption that these companies significantly over-bought capacity in the past and are accustomed to living off the excess, a strategy that probably won't fly anymore. At least these companies knew they were tracking the data manually.
Other respondents indicated that they were using file system utilities to track utilization (16 percent). I would really characterize that as manual tracking. My guess would be that most of these results are put into a spreadsheet. So that brings us to 41 percent with no real tool.
There were two responses that seemed somewhat fair. First, there were those that were using an outside firm (8 percent) to track utilization -- glad to see some reseller was successful in getting those quarterly storage audits sold. Second, there was a group of respondents that figured out that backup (9 percent) can give you a lot of details about this data. At some level it can tell you what your total capacity is (full) and what your change rate is (incremental). This assumes that all your systems are backed up and by the same tool, although that is seldom the case.
