I beleive using 22 drives in a single RAID-5 is something like BASE jumping with a large umbrella. You should at least use RAID-6, and perhaps even split up the RAID into smaller ones.

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 xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
