ATTO Technology Inc. FastStream SC Installation and Operation Manual
4.0 Configure Storage into RAID Groups
The ATTO FastStream allows configuration of storage into DVRAID, JBOD, RAID Level 0, RAID Level 1, RAID
Level 1+0, RAID Level 4 or RAID Level 5 with the ability to create multiple partitions.
RAID is a storage configuration which uses multiple
drives to increase capacity, performance and/or
reliability. The FastStream can set up an application-
ready RAID configuration automatically, you may
custom design a RAID configuration, or you may
combine a custom and an automatic configuration.
The FastStream uses all available drives when you
select
Quick Digital Video, General Digital Video,
Audio, General IT
or
Database
. Available drives
include those which are on-line and not currently
configured for RAID.
If you wish to have more than one type of RAID group
in your system, you have several options:
Set up a customized RAID group (refer to
Creating a custom setup
on page 13), then
return to the main menu and select a particular
application to use the remainder of your
attached storage.
Attach only the storage you want using an
automated setup (refer to Selecting an
application ), then attach more storage and use
either the custom or specific user processes
outlined in this chapter
Set up storage now using any of the processes
in this chapter, then modify or add to storage
using the procedures listed in Modify Storage
on
page 21.
CAUTIONCAUTION
Before creating any RAID group you
should initialize and verify the drives you
want in the RAID group. Refer to
Initialize
Drives
on page 9.
RAID improves data accessibility and
reliability during normal operations,
however, you still need a good backup
strategy for long-term protection of data.
When you have created RAID groups, you may use,
monitor and modify the storage as needed. Refer to
Monitor Storage, Configurations
on page 17,
Modify
System Values
on page 15 and
Modify Storage
on
page 21.
Selecting an application
After initializing drives or setting up new storage,
select an application from the
Initial Setup
or
Manage
page. The FastStream finds all available
drives and creates the appropriate setup using those
drives.
The most flexible choice is to use
Custom Setup
, but
you must understand your needs and your system well
to use this option.
Refer to
Design RAID Groups
on page xv of the
Appendix for more information about RAID.
