ATTO Technology Inc. FastStream SC Installation and Operation Manual
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
Drive Performance and Health
page accessible from the
Diagnostics menu. This
performance data is lost when the appliance is
powered off.
If you do not want to initialize or verify drives now,
continue on to
Configure Storage into RAID Groups
on page 11.
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.

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, 1, 1+0, 4 or 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 automatically set up an
application-ready RAID configuration. Also, you may
custom design a RAID configuration, or 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 14), 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
usingthe procedureslistedinModifyStorage on
page 30.
CAUTIONCAUTION
Before creating any RAID group you
should initialize and verify the drives you
want in the RAID group. Refer to
Ensure
Drive Integrity 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
Modify System Values on page 16, Manage ATTO
Devices, Configurations on page 35, Monitor
Storage, Configurations on page 18 and Modify
Storage on page 30.
Features you may choose
Depending on the application you choose, thenumber
of drives you choose and several other factors, you
mayhaveotherchoices tocustomizeyourFastStream
to your particular needs.
Some features are customized by you only if you use
the custom setup. Refer to
Creating a custom setup
on page 14.
Auto-Rebuild
When Auto-Rebuild isenabledandan existingRAID
group member becomes faulted, the appliance
initiates a rebuild using an available unallocated drive.
If no drives are available, the rebuild is initiated only
afteryoureplacethefaulteddriveandinitiatea system
scan to discover the drive. Hot Spares will be used
first, regardless of the Auto-Rebuild setting.
Various outcomes are available when Auto-Rebuild is
enabled...
• And an existing RAID group member becomes
faulted or unavailable, such as when a drive is
pulled out from an array, the appliance initiates
a rebuild using an available unallocated drive.
• Or if an appliance boots up with drives missing
or faulted, the FastStream tries to switch them
out automatically.
• Exception: FastStream SC 5300 requires a
system scan using the CLI command
BlockDevScan before the drive is known to be
faulted or unavailable unless data is running to
the drive, in which case the RAID member
becomes faulted and is swapped with a
replacement.

12
• If no unallocated drive is available, you must
replace the faulted drive and a rebuild begins. If
you are using a FastStream 5300, you must
initiate a system scan using the CLI command
BlockDevScan to discover the drive before the
rebuild can take place; all other appliances
automatically discover the additional drive.
• Hot Spares are not required, allowing the
maximum number of drives for data storage.
However, if you require maximum fault
tolerance, it is best practiceto have a Hot Spare
available to supply the unallocated drive for
immediate use. Refer to FastStream process:
adding or removing Hot Spares on page 33.
• Hot Spares are used first, regardless of the
Auto-Rebuild setting.
Fault Tolerance
Choose either Standard Fault Tolerance (no Hot
Spare drives) or
Maximum Fault Tolerance (which
adds Hot Spares to the system). Refer to
FastStream
process:adding orremoving HotSpares on page33
for details.
Initialization
If you have not already initialized your drives as
outlined in
Ensure Drive Integrity on page 9, you may
choose to use the
Advanced Initialization for new
drives to erase and verify drive media and correct
some soft drive errors. The RAID Group is unavailable
until the operation completes.
Choose Express Initialization to perform a quick
background initialization if you have already
completed a full initialize and verify operation. The
RAIDGroupbeinginitializedisavailableforuse during
express initialization.
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
youmustunderstandyourneedsandyour systemwell
to use this option.
Refer to
Design RAID Groups on page xix of the
Appendix for more information about RAID.

CAUTIONCAUTION
The default value is usually best. Changing
the default interleave size may degrade
performance.
15 Select the Sector Size.The RAID group sector
size must be evenly divisible by the sector size
of any member disk.
• 512 bytes is the default size for most
operating systems.
• For Windows XP (32-bit support) select 4 KB
sectors to enable large volume support
(greater than 2 TB).
16 Select a SpeedRead option. SpeedRead looks
ahead during reads and stores the data in
cache memory. The optimum setting depends
on your actual I/O and storage. You may adjust
this setting later.
• Enabling SpeedRead may boost
performance when you are running video
playback and other applications which
access data sequentially.
• Disabling SpeedRead is a better choice for
audio applications.
• SpeedRead Auto is usually the best choice
for database applications.
17 Select a Pre-Fetch option--the number of extra
stripes that are read when the SpeedRead
setting is set to enabled or auto.
18 Select an Auto-Rebuild option if it is available
for your RAID configuration (refer to Auto-
Rebuild on page 11).
19 Select a Rebuild Priority. Rebuild Priority
allows you to determine whether rebuild or I/O
transactions take precedence during rebuild
operations. If you choose low priority, for
example, rebuilds take longer but the rebuild
has minimal impact on performance.
