Description

 

 

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 hot-swapping, the system must be turned

 

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 hot-swap capability) and while data on the virtual

 

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.
