1.0 ATTO FastStream Offers Data Protection
The ATTO FastStream™ Storage Controller is an ideal solution for the cost sensitive demands of today’s
networked storage environments, offering great performance, OS independence, simplified management, and
RAID protection for all of your critical data.
Adding RAID ensures your data is protected without
compromising performance. The ATTO FastStream is
a high performance RAID storage appliance which can
be seamlessly integrated into a storage environment
without regard to any particular manufacturer, type of
drive, capacity or speed.
ATTO FastStream RAID controllers are ideally suited
for bandwidth intensive applications such as digital
film, video and audio as well as medical imaging,
digital prepress and disk to disk backup.
While RAID improves data accessibility and reliability
during normal operations, you still need a good
backup strategy for long-term protection of your data.
The ATTO FastStream is available in an industry
standard rack mount 1U enclosure.

3.0 Ensure Drive Integrity
The ATTO FastStream initialize and verify drive feature discovers and re-maps bad sectors on drives providing
reliable media for your RAID groups.
Before creating any RAID group you should initialize
and verify the drives selected to be in the RAID group
to ensure drive integrity. When selected, the
FastStream writes a pattern to the entire drive,
verifying the drive’s readiness and reliability.
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
collects performance measurements. Performance
data is available once initialization begins. You may
view it from the

If you do not want to initialize or verify drives now,

on page 13.
You may check drive integrity after you have created
RAID groups on drives in RAID groups or drives which
you wish to add to your FastStream configuring using
the initialize and verify procedure or using a read-only
scan of drives.
The read-only drive test performs a non-destructive
scan over the entire surface of each drive to identify
bad areas of disk drives and determine read
performance. It may be run while data is passing
through the FastStream.
Running this test may negatively impact performance.
Once the read-only test has completed, system
operation returns to normal.

4.0 Configure Storage into RAID Groups
The ATTO FastStream allows configuration of storage into DVRAID, JBOD, RAID Level 0, 1, 1+0, 4 or 5 for the
FastStream SC 5300 and 5700, plus RAID Level 6 for the FastStream SC 5500, 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 applicationready 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

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

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

either the custom or specific user processes
outlined in this chapter
• Set up storage now using any of the processes

CAUTIONCAUTION
Before creating any RAID group you
should initialize and verify the drives you
want in the RAID group. Refer to
Drive Integrity
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

Features you may choose
Depending on the application you choose, the number
of drives you choose and several other factors, you
may have other choices to customize your FastStream
