User's Manual

• 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 4K 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.
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 — 4K Sector Hard-Disk Drives
The following is the Hot Spare considerations (Dedicated and Global Hot Spare) for 4K sector hard-disk
drives supported on PERC 9 hardware controllers:
• You cannot assign 4K sector hard-disk drives as Dedicated Hot Spare for virtual disks created with
512B sector hard-disk drives and vice versa.
• You cannot assign 4K sector hard-disk drives as Global Hot Spare, if the virtual disk created consists of
512B sector hard-disk drives only and vice versa.
• You can assign 4K sector hard-disk drives as Global Hot Spare, if there are 4K sector hard-disk drives
and 512B sector hard-disk drives in the virtual disks created and vice versa.
NOTE: If you perform this action a warning message is displayed.

Reconfiguration Considerations — 4K Sector Hard-Disk Drives
You cannot reconfigure 4K sector hard-disk drives with virtual disks that consist of 512B sector hard-disk
drives and vice versa.
T10 Standard Protection Information (PI) — Data Integrity
Field
The introduction of PERC 9 hardware controllers in Storage Management has brought about an essential
change in storage solutions. Data integrity is an essential aspect in storage solutions, as data integrity
assures the accuracy and consistency of data stored in the system over the entire lifecycle of the data.
Data integrity is a practical solution for protecting the system against data loss in the event of a warning
of failure.
This new feature supported on PERC 9 hardware controllers allows you to configure T10 Protection
Information (PI) to virtual disks. The T10 Protection Information (PI) feature validates the data written and
read from a drive to detect errors.
NOTE: If you use the Advanced Wizard to create a virtual disk, you can enable T10 PI by selecting
the option from the Select Virtual Disk Type drop-down list.
