I don't know infotrend, but I know Netapp, Dell, Sun, and generic custom build 
ZFS servers.

My experience with netapp has been, mostly, excellent. A drive fails in the 
middle of the night, and a replacement has arrived at my desk before I even get 
to work.

My experience with Dell is almost as good - as long as you paid for a good 
warranty. A drive fails in the middle of the night, I get the alert and call it 
in. A replacement arrives same day.

My experience with Sun is ... I'm going to say it's as good as dell, because I 
believe the overall quality is about the same ... But we had a bad experience 
once where a replacement drive arrived with a newer firmware than the old 
drive, and therefore the total drive length was 1 block smaller, so it couldn't 
re-mirror. Our system remained degraded for quite a while, while we tried to 
flash old firmware onto the drive, and get additional drives fedex'd to us from 
other warehouses around the country. It was a pain. I think in the end, they 
failed to get us a compatible replacement, so we backed up the data to another 
system, then destroyed and recreated the whole system.

That situation is precisely the type of thing that should be caught by their 
QA, which is the selling point for the high cost vendors instead of the generic 
vendors. The risk of little fatal problems like that is higher with the low 
cost vendors, but it's nonzero with the high cost vendors.

If you pay the extra, you're paying for lower risk. There is no absolute right 
and wrong choice - lots of times the low cost vendor is ok, and sometimes the 
high cost vendor is *not* ok. You can only make a blind guess as to whether or 
not the difference of risk is worth the extra cost. Base it on the value and 
importance of your data and system staying up, versus difference of cost of 
hardware.
