Linode runs RAID-10 arrays in all their hosts, and their disk I/O performance reflects that (it's very fast).

As davidw pointed out, those e-mails were generated by completely customizable thresholds. If your default usage results in disk I/O rates higher than the default settings, then you should just raise the settings. The warnings are very handy if your node starts getting starved for RAM and begins to swap stuff in an out a lot.

If their I/O really is significantly better than mine (and I hear that it is often enough that it is quite possibly true... I do know that my I/O does kindof suck) then it's more than just RAID-10. I use raid 10 on all my new servers, too. But, I don't email people who use too much disk I/O. I should do that, really, as I/O is /really hard/ to effectively limit automatically. (yes, yes, IOnice. but it doesn't work very well.)

As I pointed out to davidw, I was not talking about generated emails. It was emails from humans, including from caker himself.

I have no idea what kind of storage strategy they are using, but if I got support tickets filed because i'm doing a db import, well... they're doing it wrong.
