No, it's not quite the same thing. 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
