RAID Controller Feature Description

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.
