IBM... Naah bro
We dropped IBM at the last position I was in, because as soon as they outsourced the parts manufacture to China, the server quality dropped like a rock.
Servers that would either fail out of the box with bad controllers, and broken mainboards. Or servers that would run fine, until you put them under load, then crap out consistantly.
We swapped to HP, and all those issues disappeared. The HP's were similar in price, and in some cases cheaper.
Even if they were a bit more pricey, it was worth it for the complete lack of problems we had.
HP even offered to buy our faulty IBM boxes off us, if we replaced them whith HP's.
IBM reps still come around and take us out to lunch, and we always promise to start buying IBM, when the quality improves. Still yet to happen .
