Got to say HP have been good for this too. We have had some predicted failures reported in Insight Manager and have had a new disk within 24 hours.
Usually HP are good with support, although they do have their quirks sometimes
We get our replacements within 4 hours (we pay for the priviledge though obviously).
HP support have been very good for us, we were having problems with a box and ended up deciding to swap the entire chassis, as we didn't want to reuse any hardware from it at all we needed a couple of new RAID controllers (HP 6402's - £500 each) - called HP and asked for a pair of new ones in the morning, they were there by lunchtime.
£1000 worth of controllers replaced within hours when we weren't even sure they were faulty (and we were quite up front about that). We returned the ones we pulled from the other box a couple of days later.
My only experience with Dell support recently is one of our (pretty old) dell boxes started rebooting every so often. It took nearly a week to get dell out on site, all they did in that time was asked for 6 different forms of diagnostics and tools to be run, We don't have time for that, we'll send them one set, then you they can come and fix it. That was meant to be same day response as well.
Just my experience, it may help that we spend an awful lot with HP every month but in the end, we're paying for the support and only one company is delivering it.
