IPMI is pretty slick but redundant PSU's haven't worked out so hot from what I am seeing. Granted most business owners hold onto their hardware for longer than they should but of note here a T410 had a PSU that crapped out (understandable) and the iDRAC complained at every boot about not having enough juice with the remaining PSU. It had even shut off because it was using too much wattage. What good is the redundancy there? Even after swapping the PSU out, the system shut off again and then refused to boot until I unplugged both PSU's and waited half a minute like a goddamn wireless router (during business hours no less). Redundancy usefulness factor 0. Another business saw flooding water coming down a hallway that might have become deep enough to hit the server at some point, panicked and ripped the power cords out and possibly fried the motherboard but the distributor board made it difficult to diagnose. This company thankfully chose to throw down for a new server. Then the fancy schmancy Dell VRTX CMC's that cost more than cars all had dead blade units within two or three months of deployment (five total between different sites) and still eat hard drives here and there. What happened to sticking with simple? I'll bet my scratch RAID-0 desktop for fun that is overclocked to crap outlasts these servers. The exuberance is ridiculous.
