mechanical and environmental precautions that need to be taken. Items
that need to be set prior to operating the Altos S700 enclosure are also
described here.

Note: Please read this Chapter carefully before attempting to install
or operate the Altos S700 Series enclosure.

Safety Statements

The following safety statements must be read before you install or
operate the Altos S700 Series. For language translations of these
statements refer to Appendix B.

Caution: This equipment is intended only for installation in a
restricted access location.

Caution: Before attempting to install or remove any of the
components, ensure that anti-static precautions are taken. The
minimum requirement is, a properly grounded anti-static wrist
strap and ground wire.

Caution: If any of the components are removed the resulting hole
must be blocked, by installing a component blank or replacing the
component. Failure to do so can seriously restrict air flow and
cooling.

13

Caution: This device should be connected to a power source
which carries a fuse or circuit breaker that is greater than the
rating of the shelf, but also complies with national wiring
standards.

Caution: Allow disk drives and power supplies to reach room
ambient temperature before powering on the shelf.

Caution: It is recommended that, if interconnecting equipment
resides within more than one equipment rack cabinets, these
equipment racks should be at the same ground potential.

Chapter 2 Installation and Setup14

Warning: A possible shock hazard may exist in the area of
the fan connection.

Warning: Disconnect the power cords before removing a
power supply from the enclosure.

15

Unpacking and Initial Setup

When you receive your system, visually inspect the exterior of the
packaging for any signs of damage. If any damage is found the carrier
and Acer should be informed immediately, and they will advise you of
the appropriate action. The cartons are sealed using packaging tape
which should be cut open in the normal manner. Exercise caution when
lifting out the components. At this point the contents should be
verified against the packing list and Acer should again be notified if
any discrepancies exist. Anti-static precautions must be observed
before removing any of the components.

Chapter 2 Installation and Setup16

Installing the System in an Equipment Rack

Before installing the Altos S700 Series in an equipment rack, it is
essential that the following guidelines are complied with, to ensure
the safe and efficient operation of the system. The Altos S700 Series
can be installed in open or closed equipment racks, with a front width
of 19”, by observing the environmental, electrical, and mechanical
precautions described below.

Ambient Temperature

Installation of the rack system in a standard 19” cabinet may lead to a
differential between the room ambient temperature and the internal
ambient temperature of the rack environment. The operating

temperature of the Altos S700 Series is between 5
it is not recommended that the system be continuously run at these
extreme temperatures. Consideration should therefore be given to
ensure that the room ambient temperature is compatible with these
specifications.

o

C to 40oC. However,

Air Flow

To ensure that the internal heat build up is properly dissipated into the
room environment, air flow should in no way be restricted. It is
essential that no air vents are blocked, and that the system is a
minimum of one meter from a solid surface such as a wall or partition.
Air flow through the Altos S700 Series is from front to rear.

Mechanical Loading

Consideration should be given to the loading of any equipment racks.
To maintain a low centre of gravity (thus reducing the likelihood of
instability) racks should be loaded (where possible) from the bottom of
the equipment rack upwards. This is recommended to ensure personal
safety.

Caution: When installing or removing a rack mount enclosure,
remove all disk drives. It is recommended that you work with at

least one other person when installing an enclosure. This is
necessary to prevent personal injury and damage to the enclosure.

17

Chapter 2 Installation and Setup18

Electrical Considerations

When installing the Altos S700 Series the following electrical
considerations must be applied.

Circuit Overloading

Care should be taken to ensure that the current does not exceed the
rating of the power source circuitry. This includes cabling, power
distribution units, filters and any other devices through which the main
current flows. The electrical power rating of the enclosure is 100 - 240
VAC, 10 - 5 Amps (50/60 Hz), and this must be added to the power
demands of any other electrical devices installed in the equipment rack
to arrive at a total power consumption figure. In addition, surge
currents must be catered for. Disk drives may consume twice the
amount of current at start-up time as they do during steady state
operation.

19

Setting Fibre Channel Loop Speed (2Gb or 1Gb)

The Altos S700 Series can be operated with fibre channel loop speeds
of either 2Gb (default) or 1Gb. The loop speed is set through the use of
a jumper (JP2) located on the LS Module.

Note: If the enclosure has dual LS modules the following
procedures must be applied to both LS modules.

2Gb Operation

To set the fibre channel loop speed to 2Gb operation:

1 Remove the LS Module from the front of the enclosure.

2 On the LS Module locate the jumper position JP2 (Figure 2-1).

3 Install a jumper at JP2.

4 Replace the LS module.

1Gb Operation

To set the fibre channel loop speed to 1Gb operation:

1 Remove the LS module from the front of the enclosure.

2 On the LS Module locate the jumper position JP2 (Figure 2-1).

3 For 1Gb operation there should be no jumper installed at JP2. If

one is installed, remove it.

4 Replace the LS module.

Chapter 2 Installation and Setup20

Figure 2-1 Location of Jumpers on LS Module

21

Split Fibre Channel Loop Operation (Quad Loop)

Note: Quad Loop is only available on JBOD systems

The Altos S700 Series LS module allows for split FC Loop operation,
with two dual fibre channel loops of seven disk drives each. In this split
loop mode the primary port (I/O Slot A) will form a loop using the first
seven drives, 1 to 7 (from right hand side of rackmount systems). The
expansion port (I/O Slot B) will form a second loop using the remaining
7 drives, 8 to 14 (from right hand side of rackmount systems). Default

is Single Loop (no jumper).

Note: If the enclosure has dual LS modules the following

procedures must be applied to both LS modules.

Caution: Enclosures operating in split loop mode can not be daisy
chained to other enclosures.

Setting Up Split Loop Operation

To operate the Altos S700 Series enclosure in split fibre channel loop
mode, follow this procedure:

1 Remove the LS module from the front of the enclosure.

2 On the LS Module locate the jumper position JP3 (Figure 2-1).

3 To operate in split loop mode, install a jumper at JP3.

4 Replace the LS module.

Removing Split Loop Operation

To remove split fibre channel loop operation from the Altos S700 Series
enclosure, follow this procedure:

1 Remove the LS module from the enclosure and locate jumper JP3

(Figure 2-1).

2 To remove split loop operation, remove jumper JP3.

3 Replace the LS module.

Chapter 2 Installation and Setup22

Configurations

This section describes the procedures for cabling the main
configurations of the Altos S700 Series JBOD.

Note: The following configuration procedures refer to connecting
the Altos S700 Series directly to the host system. It is also possible
to connect the system using a Hub/Switch.

Caution: Before working on the enclosure, ensure that anti-static
precautions have been taken. The minimum requirement is an
anti-static wrist strap and grounding wire.

JBOD Configurations

There are two JBOD configurations covered in this Installation Guide:

• Dual FC Loop mode (including how to daisy chain enclosures)

• Quad Loop (single enclosure with 4 FCAL loops)

Note: The following examples show the Copper/Copper I/O
Module option for illustration purposes. The configuration
procedures are identical for all I/O Module options.

Dual FC Loop Configuration

Note: For dual FC Loop enclosures there must be two LS modules
installed in the enclosure.

This section describes the procedure for connecting a dual FC Loop
configuration to your host computer, and how to daisy chain these
enclosures together.

To connect the dual FC Loop enclosure to the host:

33

Note: You will need two HBA’s in your host system, or a single

Disk Drive Spin Up Sequence

At power on, the LS module will perform its internal start up
initialization routine. Then the LS module will assert the disk drive
START_1 and START_2 motor start signals low for disk drive slots 7
through 13, which will spin up the first 7 disk drives immediately. The
LS module will then assert the disk drive START_2 motor start signal
low and leave the START_1 motor start signal high for disk drive slots 0
through 6 which will command the second seven disk drives to spin up
after a delay of 12 seconds times the modulo 8 value of the numeric
SEL_ID of the disk drive.

Once the enclosure is powered up and all 14 drives are spun up as
depicted above, the enclosure will support immediate drive spin up
with two power supplies present.

Modulo 8

The drive spin up sequence above uses modulo 8 to calculate the spin
up delay. Modulo 8 is determined by:

(SHELF ID x DRIVE NUMBER)/8 = NUMBER + REMAINDER

It is the REMAINDER value that is used for the calculation as it is
always between 0 and 7 (hence modulo 8). The drive spin up time can
then be calculated as follows:

REMAINDER x MODE PAGE SETTING = SPIN UP DELAY (Seconds)

EXAMPLE:

Spin Up Delay would be 7 x 12, or 84 seconds.

A typical Mode Page Setting is 12, so if the Remainder = 7, the

RAID Configurations

This chapter describes how to set up, configure and use the
Altos S700 Series RAID Controller. Some general information
about the RAID controller is also provided.

Altos S700 Series RAID Controller Introduction

The Altos S700 RAID Controller is a high performance controller,
providing two host fibre channel

interfaces. It is an intelligent, caching controller that supports
RAID levels 0, 1, 3, 5, 0+1, and JBOD. The controller enables
multiple hosts to access an array of disk drives, which can be
configured as one or more virtual storage devices (logical units).

The controller provides continuous access to data in the event of a disk
drive failure. When configured in a dual-active controller system, the
RAID controller also provides continuous access to data in the event of
a controller failure. This dual-active controller system is one in which
two controllers share

access to the same array of disk drives. In the
event of a controller failure, controller operations are assumed
by the surviving controller through a failover process. The failed
controller can then be removed and replaced while the system
is online. The new controller resumes processing array
operations in a failback process. During failover and failback,
write cache coherency is maintained with the disk drives.

Three circuit boards make up the RAID Controller:

• Controller: The controller circuit board contains the main

controller and peripheral functions, including processor, control­store memory, XOR engine and cache controller, and host and
device fibre channel input/output processors (IOPs).

• I/O: The I/O circuit board provides the interface to the disk drive

enclosure (device) and host as well as general support functions. It
also contains the switching power supply, which generates +3.3
Vdc and +2.5 Vdc from +5 Vdc, hot-swap circuits, and battery
backup unit (BBU) circuits.

1

• Ethernet

interface to the controller, and connections for debug and out-of­band service to the host and device PCI busses.

: The ethernet circuit board provides an ethernet

and two device fibre channel

The RAID Controller requires a minimum of two circuit boards: the
controller and I/O. The controller and I/O

circuit boards are

connected using two 38-pin controlled impedance connectors.

This option is not yet available. Please contact your sales person for availabil­ity information.

Chapter 4 RAID Configurations42

The controller, I/O, and ethernet circuit boards are assembled
into a stack with the controller and ethernet boards mounted
to a controller cover plate and the I/O board mounted to the
controller board. When the ethernet circuit board is used, it is
mounted to the controller circuit board. Figure 4-1 shows the
three circuit boards in their relative positions.

Figure 4-1 RAID Controller Circuit Boards

Features of the RAID Controller include:

• Main processor coupled with a companion chip

• Proprietary XOR engine ASIC that provides data processing XOR
function and data cache SDRAM control

• Four 2Gb-capable fibre protocol chips for the device and host ports

• Dual internal 528 MB/s, 64-bit, 66 MHz PCI buses

• Separate memory areas for processor and user data

• Scalable data cache memory: 128, 256, 512 MB DIMMs

• 128 KB NVRAM configuration memory

• Real Time Clock

• 4 MB Flash PROM

• Transparent failover/failback with multiple target ID support

The I/O circuit board includes a Battery Backup Unit (BBU) that
maintains memory content in case of AC power failure. Power for the
BBU is provided by a battery pack mounted in the fan module of the
enclosure.

43

RAID Controller Circuit Boards

This section gives a brief description of the RAID controller circuit
boards that are inside the RAID controller module.

Caution: The description of the RAID controller circuit boards
provided below is for information only. Only qualified service
personnel should open the RAID Controller module.

Controller Circuit Board

The controller circuit board oversees and regulates the flow of data
from a host through the I/O circuit board to the disk arrays in the Altos
S700 enclosure. The controller circuit board performs these operations
with a proprietary architecture, using the following components:

• Main microprocessor and companion chip

• Control-store memory

• Memory Controller/Hardware XOR Engine ASIC (XOR ASIC)

• Flash PROM

• Non-volatile RAM (NVRAM)

• Dual universal asynchronous receiver/transmitter (DUART)

• Fibre Channel I/O processors

• Cache DIMM memory

I/O Circuit Board

The I/O circuit board provides the interface between the enclosure and
a host, as well as general support functions. The I/O circuit board
provides the following:

• Connections to the host

• Connections to the enclosure

• Dual switching power supply for +3.3 V and +2.5 V

• Hot pluggability for the controller

• Support for the BBU

Chapter 4 RAID Configurations44

The I/O circuit board has two SFF optical transceivers supporting
shortwave multimode fibre on the host side and a 90-pin controlled
impedance (50 Ohm) connector on the device side. An HSSDC
connector with repeaters on the expansion loop provides for a copper
connection between one of the device channels and an expansion
module. Port bypass circuitry on the I/O circuit board enables quadplex
operation on a second host loop. The I/O board has seven LEDs to
indicate subsystem status.

RS232 Serial Port

The 3-pin, RS232 Serial Port is located on the RAID controller and
provides VT100 terminal emulation capabilities. It can be used to
configure and manage the storage array. This RS232 port applicable
when attaching to operating systems that are not supported by Acer’s
management software, or for using a CLI to create scripts.

RAID Controller Configurations

This section describes how to cable the two standard RAID controller
configurations: Single RAID Controller and Dual RAID Controller (dual
active). The procedure for daisy chaining these standard configurations
to expansions enclosures is also described. This section also describes
how to set the enclosure ID.

Chapter 4 RAID Configurations48

Setting the Enclosure ID

Each of the fourteen disk drive slots of the Altos S700Altos S700 Series
has a unique identifier assigned to it. This identifier is assigned using a
combination of the Slot number and the enclosure ID.

The enclosure ID is set, using the enclosure ID switch, located on the
rear of the Altos S700 (see Figure 4-4).

Note: The enclosure ID must be set prior to powering on the
enclosure.

Note: Each enclosure must have a separate ID when daisy chained
together.

Configurations

This section shows how to connect the RAID enclosures to a host
system(s). The procedure for daisy chaining the enclosures together is
also described.

Single RAID Controller Configuration

In this configuration only one RAID controller is installed in the
enclosure’s I/O slot. The second I/O slot must contain an I/O module or a
blank plate.

Caution: For all RAID configurations, there must be two LS
modules installed in the enclosure.

Note: The following configuration procedures refer to connecting
the Altos S700 Series directly to the host system. It is also possible
to connect the system using a Hub/Switch.

Caution: Before working on the enclosure, ensure that anti-static
precautions have been taken. The minimum requirement is an
anti-static wrist strap and grounding wire.

To connect this configuration to a host system, follow this procedure:

Connecting a Single RAID Controller to a Host

1 Plug both host cables into the host connectors on the RAID

controller (see Figure 4-5).

Note: For single HBA configurations only one host connector will
need to be used.

2 Connect the opposite ends of these host cables, to the HBA’s of the

host system.

Note: For details on your host and/or HBA refer to the
documentation that was supplied with the host / HBA.

This Chapter describes the devices used to monitor the Altos
S700 Series. The location of the monitoring LEDs and how to
interpret them is described.

Overview

The front mounted LS module is the main monitoring device of the
Altos S700 Series. This module is complemented by status and fault
LEDs, mounted on all the major components of the enclosure, such as,
disk drives, power supplies, Advanced Cooling Modules (ACMs), and
RAID Controller. All these monitoring devices are discussed in the
following sections.

Chapter 5 System Monitoring62

LS Module

The LS Module (Loop Resiliency and SES Module) provides monitoring
and control for the Altos S700 Series. The module reports status and
receives control information over the Enclosure Services Interface (ESI)
port of any of the fourteen disk drives installed in the enclosure. The LS
Module also provides loop resiliency for the Fibre Channel loop (in the
form of Port Bypass Circuits).

1

The Altos S700 Series contains one LS Module
second optional LS Module is available to provide active/passive fail­over for the enclosure services communication, and to provide a
second Fibre Channel Loop. Only one LS Module communicates (using
ESI communication) with the host system at any one time, but both LS
modules will continuously monitor the system. If the active LS Module
fails, then the ESI communication with the host system will be taken
over by the passive LS Module.

LS Module Features

• Monitoring/Control for 2 Power Supplies and 2 ACMs

• Reports status and receives control information via the FC loop

• Microcontroller for data processing, control and communications

• Volatile and non-volatile memory for the microcontroller

• Temperature sensor

• Audible alarm with manual and software disable

• FC link monitoring and status information

• Firmware download capability

• Reporting of PSU, LS module, I/O module, and backplane serial
number and revision

• I/O module and backplane type reporting

• Control of 6 front LEDs for enclosure and module status

Power Supply LEDs

The Altos S700 Series uses two AC power supplies. The AC power
supplies provide 853W peak output power and 673W continuous
output power.

The Altos S700 Series power supply has two LED indicators on it, which
are visible from the rear of the enclosure. The green Power OK LED is
on when the power supply is operating normally. This green LED is
driven by the power supply, and indicates that the power supply
output voltages are operating normally. The power supply amber Fault
LED is driven by the LS Module and power supply. This amber LED is ON
when the LS Module detects a power supply fault, or it will flash, when
the power supply Locate feature is selected.
