A commercial storage device is built in a such a way that the OS (normally on a separate HDD / PROM / flash disk / etc) can be upgraded with the suppliers pre-built patches. We're talking about doing this totally from scratch. i.e, how to build one from PC components you have / purchased from a supplier yourself. This also involves setting up the software (in this case CentOS, but FreeBSD & Solaris was recommended as well). If I wanted a commercial product, then I would have contacted the vendors and asked them this question. And if you've been following the thread, you'll see that we discussed Intel & AMD, SATA, SAS & SCSI, software & hardware RAID, etc, not which commercial device works better and which don't. It's nice to know what commercial vendors offer a way to upgrade the OS, but I'm not interested in a commercial pre-built product, I don't have that kind of capital -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff
