| | Recommended Action | |---------------|------------------------| | Home lab / Enthusiast | Do not buy a license. Use RAID 10, switch to ZFS + HBA mode, or replace the controller. | | Small Business (Production) | Buy a genuine license ($200–400) for RAID 5/6, or redesign using RAID 10. | | Enterprise (Compliance needed) | Buy official license through HPE channel. No workarounds. | | You already own a license key | Install it immediately using ssacli or SSA. |
