Configuring RAID

You must configure RAID if you change a RAID level in Smart-1 6000-L/6000-XL and if you add optional disks. If you replace a faulty disk in a hardware RAID array, the new disk synchronizes automatically.

Default and Supported RAID Levels and Storage Options:

  • The Smart-1 6000-L/6000-XL appliances have 6 disks by default.

  • In Smart-1 6000-L/6000-XL appliances with 4TB HDD/SSD, another 6 disks are optional.

  • The hardware RAID array has these default RAID configurations:

    • RAID level 6 is the default for 6 disks.

    • RAID level 60 is the default for 12 disks.

  • The available usable storage space for all the RAID level options:

Important:

  • If you change a RAID level after the Smart-1 6000-L or Smart-1 6000-XL goes into operation, the data is lost and you must install it from backups after the change.

  • If you change to a new RAID level with more redundancy, you must make sure that your backup data fits in your new RAID array's available usable storage space.

  • If you change to a new RAID level, the combinations shown in RAID Levels and Storage Options are the only supported arrays.
