Community chest: Storage firms need to pay open-source debts
Linux and *BSD have completely changed the storage market. They are the core of so many storage products, allowing startups and established vendors alike to bring new products to the market more rapidly than previously possible.
Almost every vendor I talk to these days has built their system on top of these and then there are the number of vendors who are using Samba implementations for their NAS functionality. Sometimes they move on from Samba but almost all version 1 NAS boxen are built on top of it.
