5 Press <C> and then select Save changes when the virtual disk has been
fully configured.
The Configuration Utility pauses while the virtual disk is being created.
CAUTION:
RAID 0 does not provide any data protection in the event of disk
failure. It is primarily used to increase performance.
NOTE:
Once the number of disks in a RAID virtual disk is set, it cannot be changed.
NOTE:
The maximum size of the virtual disk that contains the bootable operating
system is 2 Tb. This is due to operating system restrictions.The maximum volume
size (non-bootable) is 16 Tb.
Creating a RAID 1 Virtual Disk
A RAID 1 virtual disk offers the ability to mirror data from one physical disk
onto another one. RAID 1 volumes offer increased reliability by combining
two physical disks into a single virtual disk such that each disk contains a
mirrored copy of the other’s data. Follow these steps to create a RAID 1
virtual disk on a PERC H200 card that does not currently have a virtual
disk configured.
1 Select a controller from the Adapter List in the Configuration Utility.
2 Select the RAID Properties option.
3 Select Create RAID 1 Volume when you are prompted to create either
a RAID 0 virtual disk, a RAID 1 virtual disk or a RAID 10 virtual disk.
The next screen shows a list of disks that can be added to a virtual disk.
4 Move the cursor to the RAID Disk column. To add a disk to the virtual
disk, change No to Yes by pressing the <+>, <->, or space bar.
CAUTION:
Data on both disks will be lost. It is recommended that you back up
all data before performing these steps.
There are several limitations when creating a RAID 1 virtual disk:
• All disks must be either Dell-compliant SAS, SATA or SSD
physical disks.
• SAS, SATA or SSD physical disks cannot be used in the same
virtual disk.
• There must be 2 physical disks in a RAID 1 virtual disk.
