RAID on Smart-1 6000-L/6000-XL

Redundant Arrays of Independent Disks (RAID) combine multiple storage devices into logical units to increase data reliability and disk performance through redundancy. In fault tolerant RAID configurations, one or more disk failures do not result in data loss.

RAID on Smart-1 6000-L/6000-XL runs as a variety of storage solutions that range from mirrored disks to nested RAID. The nested RAID levels use two standard RAID modes for additional reliability and performance.

The RAID levels are set initially as defaults. Other supported RAID levels are optional.

You must configure RAID if you change:

• A default RAID level.

• The number of disks.

When a faulty disk is replaced, you do not need to configure RAID. The replacement disk synchronizes automatically.

This document shows how to:

• Change the RAID configuration from the default to a supported RAID level .

• Change the RAID configuration to include new optional disks.

• Monitor RAID status and synchronization.
