3.6. Using Raid Set/Volume Set Function Method
In "Raid Set Function", you can use the "Create Raid Set" function to generate a new RAID set. In "Volume Set
Function", you can use the "Create Volume Set" function to generate an associated volume set and configuration
parameters. . Follow the steps below to create arrays using the "Raid Set / Volume Set" method:
1. Choose "Quick Volume /Raid Setup" from the main menu. The available RAID levels with hot spare for the
current volume set drive are displayed.
2. It is recommended that you use drives of the same capacity in a specific array. If you use drives with
different capacities in an array, all drives in the RAID set will be set to the capacity of the smallest drive in
the RAID set. The numbers of physical drives in a specific array determines which RAID levels that can be
implemented in the array. RAID 0 requires 1 or more physical drives. RAID 1 requires at least 2 physical
drives. RAID 10(1E) requires at least 3 physical drives. RAID 3 requires at least 3 physical drives. RAID 5
requires at least 3 physical drives. RAID 3 +Spare require at least 4 physical drives. RAID 5 + Spare require at
least 4 physical drives. RAID 6 requires at least 4 physical drives. RAID 6 + Spare require at least 5 physical
drives. Highlight the desired RAID level for the volume set and press the Enter key to confirm.
3. The capacity for the current volume set is entered after highlighting the desired RAID level and pressing the
Enter key. The capacity for the current volume set is displayed. Use the UP and DOWN arrow keys to set the
capacity of the volume set and press the Enter key to confirm. The available stripe sizes for the current
volume set are then displayed.
4. Use the UP and DOWN arrow keys to select the current volume set stripe size and press the Enter key to
confirm. This parameter specifies the size of the stripes written to each disk in a RAID 0, 1, 10(1E), 5 or 6
volume set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256KB, 512KB, or 1024KB.
A larger stripe size provides better read performance, especially when the computer performs mostly
sequential reads. However, if the computer performs random read requests more often, choose a smaller
stripe size.
5. When you are finished defining the volume set, press the Yes key to confirm the "Quick Volume And Raid
Set Setup" function.
6. Foreground (Fast Completion) Press Enter key to define fast initialization or selected the Background
(Instant Available) or No Init (To Rescue Volume). In the "Background Initialization", the initialization
proceeds as a background task, the volume set is fully accessible for system reads and writes. The operating
system can instantly access to the newly created arrays without requiring a reboot and waiting the
initialization complete. In "Foreground Initialization", the initialization proceeds must be completed before
the volume set ready for system accesses. In "No Init", there is no initialization on this volume.
7. Initialize the volume set you have just configured.
8. If you need to add additional volume set, using main menu "Create Volume Set" function.
9. Choosing Foreground (Fast Completion) Press Enter key to define fast initialization or selected the
Background (Instant Available) or No Init (To Rescue Volume). In the "Background Initialization", the
initialization proceeds as a background task, the volume set is fully accessible for system reads and writes.
The operating system can instantly access to the newly created arrays without requiring a reboot and
