Managing Disk Arrays
This section describes how to configure and manage arrays with the Dell™ PowerEdge™
Expandable RAID Controller 3/Dual Channel (PERC 3/DC) and PERC 3/QC controllers
that are included with the PowerVault 750N or 755N NAS appliance. The PERC 3/DC and
PERC 3/QC controllers are high-performance intelligent PCI-to-SCSI host adapters with
RAID capabilities. Each channel supports SCSI data transfer rates of up to 160 megabytes
(MB) per second per channel. You can create a maximum of 40 virtual disks per controller.
The following topics are discussed:
• Recommended virtual disk configuration
•Creating virtual disks
• Deleting virtual disks
• Reconfiguring and managing virtual disks

Recommended Virtual Disk Configuration

It is recommended that each virtual disk created on your system's external SCSI enclosures
contain 11 physical drives and be configured as a RAID-5 virtual disk. Virtual disks
configured in this manner are optimized by the PERC 3/DC or PERC 3/QC adapter to
provide the best performance. You are also recommended to assign a global hotspare within
the same enclosure for each virtual disk.

Creating Virtual Disks

NOTE: The maximum supported volume size is 2 terabytes (TB).
The first step in configuring your system for improved system management is creating
virtual disks.
