LUN consolidation between different RAID groups - LUN Concatenation
LUN Concatenation is a function that is used to add new area to a volume and so expand the volume capacity available to the server. This function enables the reuse of leftover free area in a RAID group and can be used to solve capacity shortages.
Unused areas, which may be either part or all of a RAID group, are used to create new volumes that are then added together (concatenated) to form a single large volume.
The capacity can be expanded during an operation.
Note: LUN Concatenation is an equivalent function of RAID Consolidation.
Consolidating unused areas in different RAID groups, and making a new logical volume (LUN2)
"LUN Expansion function" that consolidates unused areas with existing LUNs enabling much higher capacity LUN creation is also provided.
- Provides efficient disk drive usage by making consolidating dispersed unused space into a LUN
- Provides for larger capacity logical volumes with reasonable RAID organization to minimize performance degradation upon "Rebuild" as well as improve availability in case of a failure
