Having
plenty experience with Dell I'd urge you reconsider.  All the Dell servers
we've had have arrived hideously misconfigured, and tech support gets you
nowhere.  Once we've rejigged the hardware ourselves, maybe replacing a
part or two they've performed okay.
 
Reliability has been okay, however one of our
newer R910s recently all of a sudden went dead to the world; no prior symptoms
showing in our hardware and software monitoring, no errors in the os logs,
nothing in the dell drac logs.  After a hard reset it's back up as if
nothing happened, and it's an issue I'm none the wiser to the cause.  Not
good piece of mind.
 
Look around and find another vendor, even if
your company has to pay more for you to have that blame avoidance.
