Users Guide
• 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 firmware of the PERC 9 hardware controller.
NOTE: Storage Management uses the PERC 9 hardware controller-firmware suggested span layout for RAID Level 10
virtual disk creation.
• The PERC 9 hardware controller firmware suggested span layout is same for the same set of physical disks.
• Intelligent Mirroring feature is supported on PERC 9 hardware 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 configuration 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 configuration 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 configuration (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 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 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.
Hot Spare Considerations — 4KBSector Hard-Disk Drives
The following is the Hot Spare considerations (Dedicated and Global Hot Spare) for 4KB sector hard-disk drives supported on PERC 9
hardware controllers:
• You cannot assign 4KB sector hard-disk drives as Dedicated Hot Spare for virtual disks created with 512B sector hard-disk drives and
vice versa.
• You cannot assign 4KB sector hard-disk drives as Global Hot Spare, if the virtual disk created consists of 512B sector hard-disk drives
only and vice versa.
