But the real cost of storage is management. Folks on Wall Street tell me that they spend $300,000 per terabyte per year administering their storage. They have more than one data administrator per terabyte. Other shops report one admin per 10 TB, and Google and the Internet Archive seem to be operating at one per 100 TB. The cost of backup/restore, archive, reorganize, growth, and capacity management seems to dwarf the cost of the iron. This stands as a real challenge to the software folks. If it is business as usual, then a petabyte store needs 1,000 storage admins.
