1.1 ATTO FastStream Embedded Components
The ATTO FastStream Fibre Channel to SAS/SATA RAID controller line can be seamlessly integrated into an ATX
or custom storage enclosure.
ATTO FastStream SC RAID controllers support next-
generation media and are equipped to handle the
throughputs needed by advanced disk technologies.
For installation instructions, refer to
FastStream
on page 9.
Board dimensions
The FastStream SC embedded storage controllers
feature MicroATX-size printed circuit boards (PCB).
The boards can be used in enclosures that have
adequate clearance for the DIMM socket and
allowance for connecting to internal connectors.
Width: 7.0 in. ± 0.005 in. (17.78 cm ±0.01 cm)
Length: 9.6 in. ± 0.005 in. (24.38 cm ±0.01 cm)
Height: 1.3 in. ± 0.005 in. (3.3 cm ±0.01 cm)
Temperature
Non-operating: -40 ºC to +70 ºC (-40 to 158 ºF)
Operating: +5 ºC to +40 ºC (41-113 ºF)
Humidity
Non-operating: 5% to 95% non-condensing
Operating: 10% to 90% non-condensing
Altitude
Non-operating: 50,000 feet (15,240 meters)
Operating: 10,000 feet (3048 meters)
ESD
Contact discharge: Up to ±8kV no errors
Air discharge: Up to ±15kV no errors
Real Time Clock
The Real Time Clock uses an M41T0 from ST
Microelectronics. The contents are maintained
regardless of power cycles. A rechargeable 3V Lithium
ion battery provides up to 90 days of backup power.
The charger is integrated on the circuit board. The
Lithium ion battery may explode if mistreated.

CacheAssure (optional)
CacheAssure™ provides confidence that your cached
data will remain intact in the event of an unexpected
power loss, while offering an environmentally friendly,
maintenance-free solution.
Power supply requirements
A stable power source is necessary for proper and
reliable operation. The FastStream requires an ATX
power supply with a 24-pin ATX connector. See
24-pin power connector pinouts (J1)
Appendix F.
Device Connectivity
The 2 (x4) SAS/SATA
connectors use internal
wide-SAS Small Form
Factor (SFF) 8484
connectors to connect to
either SAS or SATA
devices.
Host Connectivity
8550: four independent Fibre Channel ports connect
to Fibre Channel hosts or fabric.
8250: four independent (x4) 6-Gigabit SAS
connectors to connect to SAS Hosts.
5550: two independent Fibre Channel ports connect
to Fibre Channel hosts or fabric.
Make sure all cables are anchored securely at both
ends with the proper connectors.
WARNING
WARNING
To prevent shorting, premature failure or
damage to the battery, do not place the
board on a conductive surface such as
metal, black conductive foam or the
outside surface of a metallized ESD
protective pouch with your local
environmental regulations.
