[dns-wg] DNS hardware

Hello! I'm working at a company called Com Hem AB in Sweden, we are at the moment the biggest cabelnetwork company in Sweden. I have a question that concerns the hardware in the server that should be a primary DNS (even the hardware on the secondary DNS could be nice to know about). What I wonder most about is, should the primary DNS be build with a RAID-system? Or is that not importent of the fact there is a secondary DNS? Respectfully, Bobby Ölander NOC Com Hem AB
