Zettlab D6 NAS Setup

I have a brand-new Zettlab D6 that must be production-ready within the next four weeks. The first thing I need is a correctly configured RAID-6 array—this is the single most critical milestone—followed by a smooth rollout of the rest of the stack:

• Create and verify a RAID-6 volume, test fail-over and rebuild time
• Carve out SMB shares for several departments and map permissions to user groups
• Deploy Nextcloud behind an SSL-secured reverse proxy and wire it to OnlyOffice
• Harden the entire appliance (firewall, SSH, root lock-down, 2FA, intrusion alerts) and implement snapshot-based backups
• Migrate existing data from Dropbox and Nextdrive with minimal downtime

Everything can be done remotely as long as best practices are followed and changes are documented. I value clean command-line work, clear explanations, and predictable recovery procedures.

If you are interested, send a concise but detailed project proposal outlining the sequence you would follow, the tools you prefer (e.g., Docker), and any similar NAS or Nextcloud projects you have completed.
