I'm not sure where "enterprise" starts, but then, we have a comple of fileservers, one main box and another for backups, the latter with lower memory and bigger VDEVs. These have about 60TB each, and work well. Our backup servers (some 2x100TB + 14TB net storage) also work well, but as you can see above, we have had some issues. Paying for nexentastor for 300TB isn't really an issue :P

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
