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

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=<n>] on PERC 9 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 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
