2.1 Configure Virtual Tape
The ATTO FastStream VT 5300 allows configuration of storage into a JBOD, RAID Level 0, RAID Level 1, RAID Level 10 or RAID Level 5 Virtual Tape Library (VTL). RAID is a storage configuration which uses multiple drives to increase capacity, performance and/or reliability.
The FastStream VT 5300 appears to hosts as a tape library, allowing ISV packages to issue a set of tape library commands to perform backup and restore operations to the FastStream.
The FastStream VT 5300 configures your storage into one or two Virtual Tape Libraries (VTL) depending on the choices you make using the FastStream GUI (refer to Interface options on page 23).
For every Virtual Tape Library created on the FastStream VT 5300, an underlying RAID Group is created from the selected drives to provide the physical storage medium for the virtual tape cartridges.
You may either use the Quick Configuration or Custom Initial Setup.
•Quick Configuration: quickly generates a Virtual Tape Library after you answer a few key questions. The procedure uses all attached SCSI disks to build a single VTL. If you want to initially create more than one VTL, use custom setup. You may modify this configuration after initial setup.
•Custom Setup: allows you to configure the FastStream VT 5300 to
best suit the needs, performance and level of reliability for your application. If you want to initially create more than one VTL, use custom setup.
Whichever method you choose, you may change the configuration later. However, changing configuration erases data and may affect performance. Backup all previously stored data
and plan carefully if you choose to use the custom setup procedure.
Explanations of many aspects of the FastStream VT 5300 operation are displayed when choices are made in the FastStream GUI. Read all information and warnings.
CAUTION
Selecting Commit during configuration causes all previous storage data on the drive to be erased. Make sure all of your information is backed up.
Before beginning these procedures you may want to ensure drives are reliable by initializing and verifying the drives in your system as outlined in Initialize and verify drives on page 17.
CAUTION
Selecting Drive Initialization causes all previous storage data on the drive to be erased. Make sure all of your information is backed up before initializing drives.
