Dimensions
Width: 17 inches
SCSI ports
The two SCSI ports connect storage devices into the
Fibre Channel Storage Area Network (SAN). Each
port is totally independent from the other.
The ports are Ultra 320 SCSI busses with VHDCI
connector, downward compatible with all forms of
single-ended SCSI and all previous SCSI protocols.
Length: 11 inches
Height: 1.7 inches (1U)
Weight: approximately 10 pounds
Cooling and airflow
Operating Temperature: 0-40° C external
Humidity: 10-90% non-condensing
Air enters from the front and is exhausted out the
connector side by a blower inside the enclosure which
provides 11 cubic feet per minute of airflow. Ambient
air near the inlets should not exceed 40°C. The unit
automatically stops operation if the temperature goes
beyond this threshold.
Ethernet port
The 10/100 Base T Ethernet port is accessible from the
RJ45 connector. Local diagnostics are supported
through an integrated web server (ATTO FastStream
VT 5300 browser-based user interface), CLI, Telnet
and FTP. Includes support for DHCP, Telnet, FTP,
SNMP and ICMP.
CAUTION

2.1 Configure Virtual Tape
The ATTO FastStream VT 5300 allows configuration of storage into a JBOD, RAID Level 0, RAID Level
1, RAID Level 10 or RAID Level 5 Virtual Tape Library (VTL). RAID is a storage configuration which
uses multiple drives to increase capacity, performance and/or reliability.
The FastStream VT 5300 appears to hosts as a
tape library, allowing ISV packages to issue a set
of tape library commands to perform backup and
restore operations to the FastStream.
The FastStream VT 5300 configures your storage
into one or two Virtual Tape Libraries (VTL)
depending on the choices you make using the
For every Virtual Tape Library created on the
FastStream VT 5300, an underlying RAID Group
is created from the selected drives to provide the

Appendix A Cabling
Additional information to physically connect ports to devices and to your SAN.
SCSI cabling
Cables and devices must be chosen to maximize
performance and minimize the electrical noise
from the high-speed data transfers available with
the SCSI protocol. Cabling and termination
methods become important considerations for
proper performance. SCSI cables and devices are
subject to specific length and number limitations
to deal with electrical problems that arise at
increased operating speeds.
Cable types
Use high-quality cables rated for the type of SCSI
transfers required: well-insulated SCSI cables
ensure error free communications. Try to keep
cable lengths as short as possible to ensure higher
signal quality and performance.
Note
UltraSCSI is very sensitive to SCSI bus noise,
cable distances and the number of devices
connected on the SCSI bus. Carefully connect
your devices when working with UltraSCSI.

number of devices.

VHDCI SCSI port on the FastStream VT 5300.
Check the type of cable, cable length limit and
number of devices recommended for the port.

Set the IDs of the SCSI devices connected to
the FastStream to a value other than 7.
Use a sequential ID starting at 0 for each
device. The SCSI port has an internal factory
setting ID of 7, typical for a SCSI initiator
device.
Terminate the SCSI bus after the last device.
The FastStream VT 5300 is terminated
internally.
Keep cable lengths as short as possible to
ensure the highest signal quality and
performance. These cable lengths include the
wiring inside the devices.
Fibre Channel connections
The Fibre Channel port connects the FastStream
VT 5300 into either a Fabric or Arbitrated Loop.
Make sure all cables are anchored securely at both
ends with the proper connectors. Use the shortest
possible cable length for best performance.
The FastStream VT 5300 uses optical SFP
connectors and multimode fiber optic cable.

Appendix B Designing RAID groups
The ATTO FastStream VT 5300 provides instant hardware data protection and intelligence to existing
SCSI storage independent of the storage type.
Exhibit A-2 JBOD: Just a Bunch of Disks: no
redundancy; each disk is treated independently
CAUTION
Selecting 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.
The ATTO FastStream VT 5300 allows RAID
functionality. In general, the process begins with
individual drives also called block devices.

Note
RAID Level 0
If a drive has corrupt or outdated configuration
data, that drive cannot be assigned to any
RAID Group. Ensure all drives to be assigned
to RAID groups are configured properly. Refer
RAID Level 0 (striping) is based on the fact that
increased performance can be achieved by
simultaneously accessing data across multiple
drives, increasing data transfer rates while
reducing average access time by overlapping
drive seeks. RAID Level 0 groups provide data
that is striped across several drives. Drives are
accessed alternately, as if stacked one on top of
the other.
A RAID Group is a virtual, independent single
drive whose data is written to physical drives
according to a RAID algorithm. The ATTO
FastStream VT 5300 supports JBOD, RAID
Level 0, RAID Level 1, RAID Level 10 and
RAID Level 5.
RAID Level 0 provides no data protection. If one
drive fails, all data within that stripe set is lost.
JBOD (Just a Bunch of Disks)
JBOD (Just a Bunch of Disks) configuration
allows many individual drives to be available for
normal storage operations with no special data
protection.
The ATTO FastStream VT 5300 supports 2 to 32
drives per RAID Level 0 group.
RAID Level 0 is used by applications requiring
high performance for non-critical data.
Using the ATTO FastStream VT 5300 allows you
to concatenate several individual drives into one
large drive.

redundancy
RAID Level 0
Stripe Disk 0 Disk 1 Disk 2 Disk 3 Disk 4 Disk 5
A JBOD drive can be constructed as a special case
of a RAID Group. When multiple physical drives
are assigned to a JBOD RAID Group, their
storage areas appear as a single spanned area of
storage. The ATTO FastStream VT 5300 supports
1 to 32 drives per JBOD-configured RAID Group.

corrupted due to the failure of a single drive.
RAID Level 10
With RAID Level 1, the host sees what it believes
to be a single physical drive of a specific size: it
does not know about the mirrored pair.

data is written and read, allowing one drive to fail
without the host knowing it has failed. RAID

supports an even number of 2 to 32 drives per
RAID Level 1 group.

RAID Level 5
RAID Level 5 increases reliability while using
fewer drives than mirroring by employing parity
redundancy. Distributed parity on multiple drives
allows you to rebuild a failed drive from the
remaining good drives. The ATTO FastStream

fails.

Interference
WARNING
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may
cause interference to radio communications. It has been tested and found to comply with the
limits for a Class B computing device pursuant to Subpart J of Part 15 of FCC rules, which are
designed to provide a reasonable protection against such interference when operating in a
commercial environment. Operation of this equipment in a residential area is likely to cause
interference, in which case the user, at his own expense, will be required to take whatever
measures may be required to correct the interference.
If this equipment does cause interference to radio and television reception, which can be determined by
turning the equipment off and on, try to correct the interference by one or more of the following
measures:
•
•
Move the receiving antenna.
•
If necessary, consult an ATTO authorized
dealer, ATTO Technical Support Staff, or an
experienced radio/television technician for
additional suggestions.
Relocate the FastStream VT 5300 with respect
to the receiver, or move the FastStream VT
5300 away from the receiver.
•
Plug the computer into a different outlet so the
computer and receiver are on different branch
circuits.
The booklet How to Identify and Resolve Radio/TV Interference Problems prepared by the Federal
Communications Commission is a helpful guide. It is available from the US Government printing office,
Washington, DC 20402, Stock No. 004-000-00345-4.
Further results of FCC Testing
In certain instances, extraordinary variances in the AC power supplied to this unit will require the
operating system's normal error recovery procedure to retry the current SCSI command. In this case, the
unit can fully recover with no loss of data, and without user intervention. Note that other exceptional
conditions in addition to variances in the AC power, such as improper cabling or unrecognized
commands, may also trigger these normal error recovery procedures.
