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 requires at least 4 physical drives.
RAID 5 + Spare requires at least 4 physical drives.
RAID 6 requires at least 4 physical drives.
RAID 6 + Spare requires at least 5 physical drives.
Using the UP/DOWN key to select the RAID for the volume set
and presses
ENT to confirm it.
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.
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, or 128 KB. A larger stripe
size provides bette
r 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.
When you are finished defining the volume set, press the Yes
key to confirm
the “Quick Volume And Raid Set Setup” function.
Foreground (Fast Completion) Press Enter
key to define fast initialization or
selected the Background (Instant Available) or No Init (To Rescue Vol
ume). 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.
