AlphaServers

I seem to remember issues with Alpha's even when new. I was asked to help out somewhere running VMS on Alpha and we had a couple of failures on the CPUs over the few months I was there...
.. contrast this with working on IBM xServers and we had over 100 servers and only ever had failures on really old boxes, and then usually RAM or PSU. 
In fact given this distaste folks have for NT derived OSs  on Intel servers, its  worthy of note that even with around 120 boxes I wasn't leaping up and down every 5 mins minutes to fix them. 
Every 5 months perhaps one of the older ones would go crank but usually it was a 6 or seven year old box that was well past its best before date...
