Dell EMC Server Administrator Storage Management 9.3.1 User’s 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 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.
