RAID (Redundant Array of Independent Disks) combines multiple storage devices into logical units to increase data reliability and disk performance through redundancy. RAID arrays configured for fault tolerance can survive one or more disk failures without losing data.
The Smart-1 525, Smart-1 5050, and Smart-1 5150 RAID controllers run a variety of storage solutions that range from disk mirroring to nested RAID. The nested levels use two standard RAID levels for additional reliability and performance. RAID levels on the Smart-1 controllers are initially set as defaults. Other supported RAID levels are optional.
You must configure RAID if you change:
You do not need to configure RAID again when a faulty disk is replaced. The replaced disk is synchronized automatically.
Note - If you add disks to Smart-1 5150, place them in numerical order starting with the first available disk slot. See the numbering of the Smart-1 5150 disk slots in Storage Devices.
Note - Only RAID firmware updates provided by Check Point are supported.
