Users Guide

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 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 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 conguration 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 conguration 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 conguration (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 eciently 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 eciency 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 identied/

reported as 512B sector hard-disk drives and follows the behavior of the 512B sector hard-disk drives.
