Some of Sun's servers famously suffered big reliability problems due to using IBM SRAM as caches, which is said to have had elevated error rates due to more alpha-emitting contaminants in their particular package filler.
- kens 6y agoI was at Sun at the time (although not working on that), and these memory errors were a catastrophic problem for Sun. Customers were paying a lot of money for Sun's reliability and then systems started mysteriously having problems and Sun couldn't figure out why.
- lokedhs 6y agoI was there too. That would be the ecache problem, right? I was in the service division at the time, and yes, it was a serious issue. However, if I recall correctly it was limited to the E10K. It was the flagship machine, so of course it got all the attention, but most customers didn't suffer from it.
