ATTO Technology Inc. FastStream SC 5700 Installation and Operation Manual
2.1 Configure RAID
The ATTO FastStream SC 5700 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 5700 can
set up an application-ready RAID configuration
automatically, or you may custom design a RAID
configuration.
The FastStream SC 5700 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, ensure the
drives you want in that configuration are offline,
then follow the instructions in Modify storage on
page 23.
Before creating any RAID group 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 but
you still need a good backup strategy for
long-term protection of your data.
Initialize and verify drives
Before creating any RAID group you must
initialize and verify your drives. When selected,
the FastStream SC 5700 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 5700 collects performance
measurements. Although performance data is
available once initialization begins, complete
setting up your RAID groups before viewing the
information from the
Drive Performance and
Health page accessible from the Diagnostics
menu. This performance data is lost when the
appliance is powered off.
