This is a great story (Why we designed our own NAS Servers for use in our Data Center) where a company moves to open source software (i.e. FreeNAS) due to poor and expensive customer service.
Technetium Inc, hosting solutions, moved from Adaptec Snap servers and software to FreeNAS for their data centre NAS servers.
We need an OS now, and for that I picked FreeNAS which runs on FreeBSD. You can’t ask for a more stable operating system. And by the way, the FreeNAS OS runs from memory and boots from a CF card (no chance of the hard drive crashing and destroying the config). This custom built NAS system has turned out great, and our client is very pleased with the money we saved them.
Thanks Tod for sharing.
