– When the rebuild request is set from High or
Medium to Low in a moderate to heavily loaded
system, it can increase the disk rebuild time, but
provide better system performance.
Change the Stripe-Unit Size: This choice is available
in the Information mode only.
Attention:
After you configure an array and store data on the
logical drives, you cannot change the stripe-unit size
without destroying data in the logical drives.
The stripe-unit size is the amount of data written on a
given disk before writing on the next disk. To
maximize the overall performance, choose a size that
is close to the size of the system I/O request. You can
set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64
KB. When the stripe-unit size is 8 KB (the default
setting) or 16 KB, the maximum number of physical
drives supported in an array is 16. When the
stripe-unit size is 32 KB or 64 KB, the maximum
number of physical drives supported in an array is
eight. (See “Interleave Depth and Stripe-Unit Size” on
page 5 for more information.)
Scan for New or Removed Ready Drives: This
choice is available in the Information mode only.
When you select this choice, the configuration program
scans all channels on the ServeRAID controller for new
or removed Ready drives.
The following choices appear on the Actions pull-down
menu when you select the Arrays icon or a specific array
icon from the Main Tree:
Create an Array: This choice appears in the
Information mode if you select the Arrays icon and
Ready drives are available. When you select this
choice, the configuration program switches from the
Information mode to the Configuration mode.
Delete All Arrays: This choice is available in the
