Features

Virtual disks (general) Up to eight virtual disks are supported.

The PERC S100 adapter and PERC S300 adapter allows:

• Creating virtual disks of different RAID levels on a single

controller.

• Creating different RAID level virtual disks on the same

physical disk, to adapt each virtual disk to the I/O that it

processes.

• Building different virtual disks with different characteristics

for different applications.

The PERC S100 adapter and PERC S300 adapter does not

allow:

• Creating a virtual disk from a mix of different type physical

disks. For example, a RAID 10 virtual disk cannot be created

from two SATA-II HDD physical disks, a SAS HDD physical

disk, and a SSD physical disk. All of the physical disks must

be the same interface (SAS or SATA) and drive type (HDD

or SSD).

• Selecting a physical disk as a dedicated hot spare if the

physical disk is a different type from the physical disk or

disks.

A virtual disk refers to data storage created by the controller

from one or more physical disks. Although a virtual disk can

be created from several physical disks, it is seen by the

operating system as a single disk.

The capacity of a virtual disk can be expanded online for any

RAID level, without the operating system being rebooted.
