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.
