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 firmware on the PERC 9 and later of 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
and later of hardware controllers.
The span layout for RAID Level 10 virtual disk created from the Express Wizard on PERC 9 and later of hardware
controllers uses the span layout as recommended by the firmware of the PERC 9 and later of hardware controller.
NOTE: Storage Management uses the PERC 9 and later of hardware controller-firmware suggested span layout for
RAID Level 10 virtual disk creation.
The PERC 9 and later of hardware controller firmware suggested span layout is same for the same set of physical disks.
Intelligent Mirroring feature is not supported on PERC 9 controllers and later of PERC controllers.
When you create a virtual disk using the Advanced Wizard on PERC 9 and later of hardware controllers the span layout
information under Selected Physical Disks will not be displayed.
Sliced RAID Level 10 virtual disk creation on PERC 9 and later of 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
and later of hardware controllers.
When you import a foreign configuration from hardware controllers prior to PERC 9 and later of hardware controllers to
PERC 9 and later of hardware controllers, the span layout for RAID Level 10 virtual disk remains the same.
When you import a foreign configuration for RAID Level 10 virtual disks from PERC 9 and later of hardware controllers to
other PERC 9 and later of hardware controllers the span layout does not change.
NOTE:
Importing a foreign configuration (other than RAID Level 10 virtual disks) from PERC 9 and later of 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 and later 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 efficiently 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
efficiency and error correction capabilities.
Storage Management supports virtual disk creation on 4KB sector hard-disk drives connected to PERC 9 and later of 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.
Support for PERC 9, PERC 10, and PERC 11 hardware controllers 89
