I also agree that most of Dell's hardware is very linux friendly on all flavors but there are some that are tied to Red Hat (I'm talking as far as simple installation -- anything can be compiled). This is especially true with a lot of the PERC controllers and, to be honest, I think PERC is my biggest gripe about Dell. From my experience they have been total crap. I used to work for a company that used all Dell (we're talking about 15 racks of dell servers) and I was daily walking around reseating drives because PERC controllers (incorrectly) said it was a bad drive. Once you'd pull a drive out and put it back in it would think "oh, new drive" and would run for months or years without a problem. The biggest issue here tho is that the PERC controllers always seemed to put a heavy burden on the machines while rebuilding (definately more so than a lot of controllers out there like 3ware). Because we were constantly making drives rebuild we lost a lot of performance overall. The other huge issue I've had in the recent 6 months or so is their rail systems (primarily for the 1950 and 2850 servers). Aside from that I think Dell does have a good touch of what HP has as far as rigging hardware, however, they aren't nearly as bad as HP and some of that is even offset by the fact that you can typically find Dell parts very easily from non-Dell vendors. > -SuperMicro always seems attractive to me in some way, but has always > fallen short for one reason or another.

Between all of my customers I probably have no less than 500 drives in supermicro systems that I deal with and I've never actually had one break on me -- well, with the exception of leaving one on the floor and stepping on it :) > On the new chassis, it is near impossible to remove more than one > column > of drives at a time because of the low clearance between columns of > drives.

This is definately a huge frustration of mine but its worth it to be able to avoid the pitfalls of many other servers. I, however, have never seen the difficulty removing drives like you mention. I'm curious, did you buy your systems from supermicro directly or from a supermicro system integrator? This can make a huge difference. > > Best Regards, > Dennis Little
