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.
When you create a virtual disk using the Advanced Wizard, you can select the physical disk sector from the Sector Size
drop-down list. The options available are:
512B
4KB
You cannot use both 4KB sector hard-disk drives and 512B sector hard-disk drives for a virtual disk creation as mixing of
hard-disk drive sectors is not allowed in Storage Management.
NOTE:
If the system contains any 512e sector hard-disk drives, the 512e sector hard-disk drives are identified/reported
as 512B sector hard-disk drives and follows the behavior of the 512B sector hard-disk drives.
