3.4Creating a RAID 0 Volume
A RAID 0 volume, also referred to as Integrated Striping (IS), offers the ability to stripe data across multiple hard disks. This can increase storage capacity and performance by combining multiple disks into one logical volume.
Note – Use RAID 0 with caution. The only advantage of RAID 0 is to improve the overall disk performance by striping data over several disk drives. By doing this, it decreases reliability because the failure of any drive within the striped volume results in a complete loss of data. In addition, any disk drive included in a RAID 0 volume becomes
Follow these steps to create a RAID 0 volume on an adapter that does not currently have a volume configured.
1.In the Configuration Utility, select an adapter from the Adapter List screen.
2.Select the RAID Properties option.
3.When you are prompted to create either an IS volume, an IME volume, or an IM volume, select Create IS Volume.
The next screen shows a list of disks that can be added to a volume.
4.Move the cursor to the RAID Disk column. To add a disk to the volume, change the “No” to “Yes” by pressing the + key, - key, or space bar.
As disks are added, the Array Size field changes to reflect the size of the new volume. There are several limitations when creating a RAID 0 volume:
■All disks must be SAS (with SMART support).
■Disks must have
■There must be at least two drives in a valid volume.
■Hot spare drives are not allowed for RAID 0 volumes.
Note – RAID 0 does not provide any data protection in the event of disk failure. It is primarily used to increase speed.
