The left side of the slider scale shows how much drive capacity is available for data storage, while the right side indicates how much capacity is required for storing parity or mirrored information. (RAID overhead is not needed for RAID 0.) The default logical drive size first shown in this box is the maximum available for your drive array. To create more than one logical drive on the array, reduce the logical drive size by typing a smaller number in the scroll box. ACU allows you to create up to 32 logical drives per array. Click Advanced to display the Create Logical Drive - Advanced Features screen, where you can enable or disable the maximum boot size for a logical drive. The default boot size is 32 sectors (16 kbytes) per track, and the maximum boot size is 63 sectors per track.

Table 7-3:
Optimum Stripe Size for a Given Application
Type of Server Application
Suggested Stripe Size Change
Mixed read/write
Accept the default value
Mainly sequential read (such
as audio/video applications)
Use larger stripe sizes for best
performance
Mainly write (such as image
manipulation applications)
Use smaller stripes for RAID 5
Use larger stripes for RAID 0, RAID 1+0
The
Logical Drive Size
box shows how much drive capacity is available on the
selected logical drive when using the chosen RAID level. The left side of the slider
scale shows how much drive capacity is available for data storage, while the right
side indicates how much capacity is required for storing parity or mirrored
information. (RAID overhead is not needed for RAID 0.)
The default logical drive size first shown in this box is the maximum available for
your drive array. To create more than one logical drive on the array, reduce the
logical drive size by typing a smaller number in the scroll box. ACU allows you to
create up to 32 logical drives per array.
Click
Advanced
to display the
Create Logical Drive – Advanced Features
screen,
where you can enable or disable the maximum boot size for a logical drive. The
default boot size is 32 sectors (16 kbytes) per track, and the maximum boot size is 63
sectors per track.
