Is it possible that the drives that died were in similar physical locations? For example, if you have a dodgy power supply, perhaps the last bank of drives gets lower quality power, or depending on the temp of the case and airflow, perhaps the top bank of drives run significantly warmer?
- KaiserPro 12y agoThats certainly possible, although we've done our best to minmise it. We have coldlogik water cooled racks which almost eliminate hot spots. The other thing to note is that 4000 drives fit into less than 7 racks. (yup, I was surprised too) so they are all in the same place. We also have two transformers, just for us, with lots of sexy power smoothing (but no UPS, and yes that's a bad thing.) It could be the raid enclosure its self, that might be part of the problem. However they should be identical, with the same firmware.
