4.2.7 RAID GROUPS OVERVIEW
RAID Groups allow Enter values in all fields and click Create to create the RAID Group.
FIELD DEFINITION
RAID Group
Label
Enter an identifiable name for the RAID group. This value can be any string (up to 8
characters including blank spaces) to help users identify this volume.
RAID Group
Select a Group ID from the available ID list. The maximum number of RAID Groups
per controller is 8, so Group ID can be any number between 0 and 7, inclusive.
Configuration
Select which RAID level is to be used to configure these members:
• Contiguous (for virtual disk).
• Concatenated (for multiple concatenated segments).
• Striped (for RAID 0)
• Mirrored (for RAID 1)
• Mirrored Striped (for RAID 10)
• Parity RAID (for RAID 5)
Capacity
Select a value to define the total usable capacity of the RAID Group or manually
enter the volume size in gigabytes (GB). Selecting MAX will create the largest RAID
set possible with the drive(s) selected.
Chunk Size
Select a value to define the chunk size (stripe size) for performance tuning. In
general, large stripe sizes are best for large files that are accessed sequentially (for
example, media streaming files) and smaller sizes are better for randomly accessed
data like databases. This parameter is not used for Contiguous (JBOD),
Concatenated, and Mirrored configurations.
Rebuild
Priority
Select a value to identify how quickly the controller should rebuild data on a disk
after a hardware failure. A value of 1 is the lowest priority and will take the longest
to rebuild. A value of 10 is the highest priority and will rebuild the fastest, but may
require more CPU resources, which might affect the computer’s performance. This
parameter is not used for Contiguous (JBOD), Concatenated, and Striped
configurations.
