Problem
You re the chief information officer of a rapidly growing company. You manage several dozen small and medium servers and are about to acquire your first mainframe to set up a data warehouse. You currently have AIT tape drives, but you wonder whether they ll be enough in the future. You're concerned about tape drive capacity, reliability, and cost and are considering switching to another tape format or technology. Which of the current tape formats provides the highest capacity at the lowest cost? Which is most reliable? Which is least likely to become obsolete 5 years from now? Which, if any, should you buy?
