Non-stop LUN migration to different RAID groups - RAID Migration
RAID Migration is a function that moves a volume to a different RAID group with the data integrity being guaranteed. This allows easy redistribution of volumes among RAID groups in response to customer needs. RAID Migration can be carried out while the system is running, and may also be used to switch data to a different RAID level changing from RAID5 to RAID1+0, for example.
The volume number (LUN) does not change before and after the migration. The host can access the volume before, during, or after a migration without being affected by the volume number.
The following changes can be performed by RAID Migration.
Volumes moved from a 960GB drive configuration to a 3.84TB drive configuration
Volumes moved to a different RAID level (RAID5 ⇒ RAID1+0)
"LUN Expansion function" that allows for logical volume (LUN) expansion during migration is also provided.
- Provides non-stop logical volume migration to different RAID groups comprised of larger capacity disk drives
- Enables non-stop migration of RAID groups to match specific needs for higher reliability and performance
