ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
3.1 Components
The Diamond Storage Array has been designed to be easy to use, maintain and upgrade. It features a
durable steel outer case and modular components in either a floor or a rack mount model.
Immediately upon receipt, check the shipping
carton for damage from mishandling. Contact us
at once via the means that is easiest for you (refer
to
Contact ATTO Technology, Inc. on page viii) if the
carton has been mishandled or displays any signs
of damage.
The front of the Diamond Storage Array provides
access to the management card and disk drive
sleds. The rear of the unit holds the Host Interface
Cards, power supplies and blower assemblies.
CAUTION CAUTION
All modular components must be replaced
by qualified personnel only.
Floor model
The management system card is at the top front of
the case. At its center is a DB-9 serial RS-232
port, a connection for setup, monitoring and
upgrade of the unit from any computer system
with an RS-232 interface. The optional 10/100
BaseT Ethernet management services card
enables Telnet-based monitoring and
management. It also provides the ability to update
the firmware in the array via FTP.
LEDs to the port’s
right indicate fault,
unit ready, Host
Interface Cards A
and B installation
status, and the power
status for each power
supply.
Below the
management system
card are individual
disk drive sleds
which also have
LEDs for each
drive’s status. Each
sled contains two hard drives. Up to 24 hard
drives may be installed on the 12 sleds. Empty
bays should be covered by blank faceplates or
empty sleds. Access is provided by loosening two
screws and gently pulling on the sled handle.
On the rear of the unit are blowers which support
hard drive, cabinet and power supply cooling. The
blowers are held in by removable screws. Correct
operation is displayed by a LED at the top of each
panel.
The power supplies for the array, also in the rear
of the unit, are accessible by loosening two screws
and pulling on the power supply module handle.
The power standby on/off switch is at the top of
each module. A yellow LED indicates caution
and a green LED indicates on. The power cord
socket is at the bottom of each power supply.
Between the power supplies and blower
assemblies are two slots that hold the Host
Interface Cards. The HIC is the connection point
into the array and is available in three options: 1-
Gigabit Fibre Channel, 2-Gigabit Fibre Channel,
or Ultra 160 SCSI. Host Interface Cards have fault
and on-line or fault and activity LED indicators,
depending on the model.
SCSI The SCSI card faceplate has a rotary
binary-coded hex switch to set the SCSI ID of the
array. The SCSI card also has an in channel, to
connect via cable to the unit’s communication
source, and an out channel, available for daisy-
chaining arrays together or to complete
termination using an external LVD terminator.
Rack mount
The system management card is at the left front of
the case. At its center is a DB-9 serial RS-232 port
which allows a connection for setup, monitoring
and upgrade of the unit from any computer system
with an RS-232 interface. The optional 10/100
