Mirror rebuilding | A broken mirror can be rebuilt after a new physical disk is |
| inserted and the physical disk is designated as a hot spare. |
| The system does not have to be rebooted. |

Online Capacity | OCE is a process that allows you to add storage capacity to an |
Expansion (OCE) | existing virtual disk. In most cases additional storage capacity |
| can be added without taking the system offline. However, if |
| an additional physical disk needs to be added and the system |
| does not support |
| off. |
| OCE enables you to increase the total storage capacity of a |
| virtual disk by integrating unused storage with the virtual |
| disk. |
| Data can be accessed while the physical disks are added (if a |
| system has |
| disk is being redistributed. |
| For Volume and RAID 1, OCE expands the virtual disk by |
| using the available space of the physical disks that are already |
| members of the virtual disk. For RAID 0, RAID 5 and RAID |
| 10, additional capacity can be attained by adding physical |
| disks to the virtual disk. |
|
|
Physical disks | The PERC S100 adapter supports up to four SATA HDD or |
(general) | SSD physical disks. The PERC S300 adapter supports up to |
| eight SAS or SATA HDD physical disks. |
| NOTE: The physical disks in a virtual disk must be the same |
| interface and drive type (HDD or SSD). For example, you cannot |
| mix a SATA and SAS interface (HDD or SSD), or HDD and SSD |
| physical disks, in the same virtual disk. |
| A maximum of eight physical disks can be used for RAID 0 |
| and RAID 5. A maximum of two physical disks can be used |
| for RAID 1. A maximum of four physical disks can be used for |
| RAID 10. |
| If a physical disk fails during system startup, the controller |
| identifies the failed physical disk as follows: |
| • At the PERC Virtual Disk Management utility by |
| highlighting the failed physical disk in a virtual disk in red. |
