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.

Hot Spare Considerations — T10 Protection Information

Capability

The following is the Hot Spare considerations (Dedicated and Global Hot Spare) for T10 Protection Information (PI) supported physical

disks on PERC 9 hardware controllers:

• Only T10 PI supported physical disks can be assigned as a Dedicated Hot Spare to T10 PI enabled virtual disks.

• Physical disks which are T10 PI supported or unsupported can be assigned as Dedicated Hot Spare to T10 PI disabled virtual disks on

PERC 9 hardware controllers.

• If a T10 PI enabled virtual disk is present along with T10 PI disabled virtual disk, assigning a physical disk which is T10 PI unsupported as

Global Hot Spare will be successful.

NOTE: An error message is displayed if you perform this action.

• If only T10 PI disabled virtual disks are present, a T10 PI supported physical disk can be assigned as Global Hot Spare.

• A T10 PI enabled virtual disk cannot be reconfigured using a T10 PI non-capable physical disks
