About the Dell™ PowerVault™ DL Backup to Disk
Appliance and the Backup Exec Storage Provisioning
Option
The Backup Exec Storage Provisioning Option provides you with automated
discovery, provisioning, and management of the disk storage resources that are
connected to the Dell™ PowerVault™ DL Backup to Disk Appliance (DL Appliance).
Table 1-1 Features of the Storage Provisioning Option
Description Feature
Backup Exec automatically creates and
configures striped with parity (RAID 5)
virtual disks from the physical disks it
detects in the DL Appliance. Automatic virtual disk creation and
configuration
Backup Exec discovers new storage arrays
and the virtual disks that you add to a
storage array. If you create virtual disks by
using the Dell™ OpenManage™ Server
Administrator, Backup Exec also detects
those virtual disks. Discovery and provisioning of new storage
arrays and virtual disks
Backup Exec collects statistical information
to predict the amount of disk space that is
required on the storage arrays. Alerts are
sent if the available disk space does not meet
the predicted amount of disk space that is
needed. Trend analysis of disk space usage
Backup Exec sends an alert when available
disk space reaches each of three thresholds
that you set for a virtual disk. Alerts for low disk space
Backup Exec logically groups multiple Serial ATA (SATA) physical disks that are
attached to a PowerVault™ MD1000 enclosure into one or more disk groups. From
these disk groups, Backup Exec then creates multiple striped with parity virtual
disks, which can be used as destination devices for jobs.
Up to three enclosures can be daisy-chained together. By daisy-chaining enclosures,
Backup Exec can use the additional enclosures to increase the number of disk
groups and virtual disks it creates.
With Backup Exec installed, the DL Appliance can be considered as a Backup Exec
media server.
