RAID Level 10 Virtual Disk Creation With Uneven Span
RAID Level 10 virtual disk creation with uneven span feature is available on Storage Management User Interface (UI) and Command Line
Interface (CLI). For information on Storage Management CLI, see Server Administrator Command Line Interface Guide.
• Based on the minimum (and even) number of physical disks selection the rmware on the PERC 9 hardware controller recommends the
preferred span layout.
NOTE: RAID Level 10 virtual disk creation command from Storage Management CLI does not support optional parameter
spanlength on PERC 9 and PERC 10 hardware controllers.
• The Advanced Wizard does not provide the option to select span length for RAID Level 10 virtual disk creation on PERC 9 hardware
controllers.
• The span layout for RAID Level 10 virtual disk created from the Express Wizard on PERC 9 hardware controllers uses the span layout
as recommended by the rmware of the PERC 9 hardware controller.
NOTE: Storage Management uses the PERC 9 hardware controller-rmware suggested span layout for RAID Level 10
virtual disk creation.
• The PERC 9 hardware controller rmware suggested span layout is same for the same set of physical disks.
• Intelligent Mirroring feature is not supported on PERC 9 controllers and later PERC controllers.
• When you create a virtual disk using the Advanced Wizard on PERC 9 hardware controllers the span layout information under Selected
Physical Disks will not be displayed.
• Sliced RAID Level 10 virtual disk creation on PERC 9 hardware controllers support uneven span.
• Grouping of selected physical disks for RAID Level 10 virtual disk through the Advanced Wizard is not supported on PERC 9 hardware
controllers.
• When you import a foreign conguration from hardware controllers prior to PERC 9 hardware controllers to PERC 9 hardware
controllers, the span layout for RAID Level 10 virtual disk remains the same.
• When you import a foreign conguration for RAID Level 10 virtual disks from PERC 9 hardware controllers to other PERC 9 hardware
controllers the span layout does not change.
NOTE
: Importing a foreign conguration (other than RAID Level 10 virtual disks) from PERC 9 hardware controllers to
hardware controllers prior to PERC 9 is not supported.

Support For Advanced Format 4KB Sector Hard-Disk
Drives
From the introduction of PERC 9 family of hardware controller support in Storage Management, users using legacy 512B sector hard-disk
drives can now transition to Advanced Format 4KB sector hard-disk drives. 4KB sector hard-disk drives utilize the storage-surface media
more eciently by combining data that would have been stored in eight 512B sector hard-disk drives into one sector of 4096B (4KB). This
data-combining feature in 4KB sector hard-disk drives results in improved data eciency and error correction capabilities.
Storage Management supports virtual disk creation on 4KB sector hard-disk drives connected to PERC 9 hardware controllers.
NOTE
: 4KB sector hard-disk drives are not supported on controllers prior to PERC 9 family of hardware controllers. If the 4KB
sector hard-disk drive is connected to any hardware controller prior to PERC 9, the 4KB sector hard-disk drive is displayed as
Unsupported.
