1.0 ATTO FastStream Overview
The ATTO FastStream™ Storage Controller was engineered for real-time applications which require managed
latency. Offering great performance, OS independence, simplified management, and RAID protection for all of
your critical data, FastStream is an affordable SAN solution.
Adding ATTO RAID ensures your data is protected
without compromising performance. ATTO
FastStream Storage Controllers are high performance
RAID storage devices which can be seamlessly
integrated into any storage environment without
regard to any particular manufacturer, type of drive,
capacity or speed.
ATTO FastStream controllers are ideally suited for
bandwidth intensive applications such as digital film,
video and audio as well as 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.
ATTO FastStream Storage Controllers are available in
industry standard rack mount 1U enclosures.

DHCP enabled. It is best if you have access to
a DHCP server.
1 Work from the computer attached to the
FastStream Ethernet port. From the CD
supplied with your FastStream, run the
QuickNav Utility QuickNAV-windows.exe for
Windows or QuickNAV-Mac for Mac OS X.
2 Locate the FastStream with the serial number
recorded earlier.
3 Highlight the serial number.
4 Click Next.
If a DHCP server is available on your network,
an address is assigned automatically by the
server. Note the assigned address:
_____________________________________
If you do not have a DHCP server, get an IP
address and subnet mask from your network
administrator, type it into the area provided, and
click on Next.

ATTO Technology Inc. FastStream SC Installation and Operation Manual
3.0 Ensure Drive Integrity
A key component to ATTO’s DriveAssure™ technology is the ATTO FastStream’s “Initialize and Verify drive”
feature which discovers and remaps bad sectors on drives, providing reliable media for your RAID Groups.
Before creating any RAID Group you should Initialize
and Verify the drives you want 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
Drive Performance and Health
page accessible from the
Diagnostics menu. This
performance data is lost when the controller is
powered off.
If you do not want to initialize or verify drives now,
continue on to
Configure Storage into RAID Groups
on page 21.
Check drive integrity after you have created RAID
Groups on drives which you wish to add to your
FastStream configuration. This can be accomplished
by using the
Initialize and Verify procedure or 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 Drive Test has completed,
system operation returns to normal.
Before creating RAID Groups
1 If you are not already in the ExpressNAV
Storage Manager, type the IP address of your
controller in a standard browser. On the splash
screen, click Enter Here. In the box provided,
type in your user name and password, and click
OK.
2Select
Initialize and Verify Drives.
3 Click Next.
4SelectInitialize and Verify Drives.
All eligible drives are highlighted in green; the
system only initializes highlighted drives.
5 Click Commit.
CAUTIONCAUTION
Do not restart the FastStream or
disconnect or power cycle drives during
Drive Initialization and Verification or you
must start the verification process from the
beginning.
6 A warning box appears. In the warning box,
verify that you want to complete the
configuration by clicking on Yes. Clicking on No
ends the procedure without making a change.
7 When the process is complete, the
Performance tab, in the Drive Performance
and Health page, appears.
The drive(s) selected are now initialized and verified.
All data on the highlighted drives has been erased and
you may continue with
Configure Storage into RAID
Groups on page 21.

ATTO Technology Inc. FastStream SC Installation and Operation Manual
3.1 Drive Diagnostics
You may determine the performance of drives attached to the FastStream using various displays and tests in
ExpressNAV Storage Manager.
The following instructions assume you have already
set up at least one RAID Group.
The ATTO FastStream collects various metrics to
measure performance for physical drives attached to
the FastStream during normal system operation and
drive initialization and verification.
New performance data is updated every 60 seconds
which impacts performance slightly, even if you
minimize the browser window. Exit the ExpressNAV
Storage Manager completely whenever you need
maximum performance.
