ATTO Technology Inc. FastStream SC 5300 Installation and Operation Manual
2.1 Configure RAID
The ATTO FastStream SC 5300 allows configuration of storage into DVRAID, JBOD, RAID Level 0,
RAID Level 1, RAID Level 10 or RAID Level 5, all with partitions.
RAID is a storage configuration which uses
multiple drives to increase capacity, performance
and/or reliability. The FastStream SC 5300 can
set up an application-ready RAID configuration
automatically, or you may custom design a RAID
configuration.
The FastStream SC 5300 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 another type of RAID
configuration in the same system, you should
ensure the drives you want in that configuration
are offline, then follow the instructions in Modify
storage on page 21.
Before creating any RAID group you should
initialize and verify the drives you want in the
RAID group.
CAUTIONCAUTION
Clicking on Commit during RAID
configuration causes all previous storage
data on the drive to be erased. Make sure
all of your information is backed up before
setting up RAID groups.
RAID improves data accessibility and
reliability during normal operations,
however, you still need a good backup
strategy for long-term protection of your
data.
Initialize and verify drives
Before creating any RAID group you should
initialize and verify your drives to ensure drive
integrity. When selected, the FastStream SC 5300
writes a pattern to the entire drive.
CAUTIONCAUTION
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.
During initialization and verification, the
FastStream SC 5300 collects performance
measurements. Performance data is available
once initialization begins. You may view it from
the
Drive Performance and Health page
accessible from the
Diagnostics menu. This
performance data is lost when the appliance is
powered off.
