Combined cleverly with datasets and quotas, they make for very easy management of disk resources when needed. The FreeNAS model of boot environments is awesome, and I hope pfSense takes those up as well. It makes upgrades less stressful when you can just click a button to revert. As for the ECC, see this study https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/35162.pdf for example. It is slightly old, but RAM hardware is not that much advanced since then. Basically, if you have a few gigs of RAM in your machine, it *will* produce bit errors. There are other studies that back this up too, and they are more recent. Personally, I don't understand why any computer, desktop or server, made these days is without ECC. My desktop has 16GB RAM with room for 16 more. I'm sure there are flipped bits in some of my work somewhere, but I'll never really know. If I'm lucky, the flipped bits are on unused sections of code loaded from the disk into RAM. _______________________________________________ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
