In July 2009, Varun Mehta—a first-time founder—was driving toward a courageous decision: giving up a sure success for a long shot at disrupting a major category.
Nimble Storage, the company he started 18 months earlier with Umesh Maheshwari, was testing its product, a flash-based caching appliance, or “cacher,” that sat on top of existing storage systems and dramatically improved I/O performance. Beta customers loved the cacher and it looked like a hit. Shockingly, Varun and Umesh wanted to kill it. Instead, they proposed building a primary-storage system that incorporated flash, a much bigger opportunity, but a far riskier one.
