While browsing the net I found a server with a raid controller
HP Smart Array P400/512MB BBWC Controller
How does one know what this is, if it is any good or so? I guess they
just stuck their "HP" label onto some other raid controller?
I could write HP but I guess that wouldn't help much. And I could also
look through the archives for the mailinglist. When I find the
time,I'll do so and try to create a wiki page.
The problem with this kind of built-in hardware is that it might suck,
and then you can't plug in any other hardware in the box.
