Is this bad?


Thanks for your input, but...

.... that will not give me hot-swap capability. Plus it gives me the overhead of worrying about another whole linux system (and my linux sysadmin skills are marginal, I'm much better with Solaris). We actually do have some internal raids like this on some of our linux systems, and they're a pain to deal with if you lose a disk. We also have 12-disk external raid box with hot swap capability hooked up to a Sun and it's so simple to deal with if a single disk goes south. Unfortunately, the size of the disks is small and going the Sun route is prohibitively expensive right now.

I started my search by just looking for a raid card and external box with hot-swap capability that I could hook up to one of our existing linux boxes, but again, most of the stuff I found seemed to be geared toward windows. I'm no linux guru, and when faced with installing cards, flashing bios, installing drivers (if they exist), etc, I was a bit daunted. When I heard about a standalone networked solution, it seemed ideal. Also, a lot of the good-looking raid cards were PCIe, and we don't seem to have that type of slot on our linux boxes. Others were so expensive as to be prohibitive.

Also, one of my colleagues previously set up a raid in an external box hooked to a linux machine (he was much more profficient than me at linux admin) and it crashed and burned at some point. We never could figure out exactly why, but it was suggested that it was somehow linked with having the raid card and the disks powered by different power supplies. That could be a totally bogus conclusion, but it does make me leary.

Anyway. These standalone networked stoarge devices seem a simple and reasonably priced alternative - if they will do what they seem to promise.

So if anyone has any input on any of the models mentioned, I would greatly appreciate it.

Thanks.
