1. A Brief Description of iSCSI Technology

What is iSCSI?

iSCSI is a technology that allows a data storage device to be accessed over a TCP/IP network using
SCSI protocols. When your computer’s OS receives a request for data access, it generates a SCSI
command and then sends an IP packet across a network or direct ethernet connection. A software utility
known as an iSCSI Initiator is used to generate the SCSI commands. Such a utility must be installed on
the computer before it can access an iSCSI storage device.

What is the benefit of iSCSI?

An iSCSI storage device can be placed anywhere throughout a network, so the device can reside at a
great distance from the computer which accesses it. It is also a very fast connection when used on a
gigabit network, achieving speeds of 100MB/sec or more. The connection it uses (RJ45 – standard
ethernet port) is commonly found on desktop and laptop computers, so there is no need to purchase
potentially expensive host bus adapters to provide a connection.

What is iSCSI not?

iSCSI storage devices are not Network Attached Storage (NAS) devices. They have no built-in server
capabilities and therefore cannot be accessed by more than one computer at a time. Multiple computers
can only access the data if the iSCSI device is first attached to a single computer which is then set up as
a server.

2. Pre-Setup Steps

2.1 Install iSCSI Initiator software on your computer. This is a required step. Any

computer must have Initiator software installed before it can connect to an iSCSI device such as RAX-IR.
Both freeware and commercial software utilities are available for this purpose. Note: Initiator software is
not required for additional computers that share files with the host computer attached to RAX. In such a
scenario, the host computer acts as a server to the other computers. Only the computer directly
accessing RAX needs Initiator software.

Windows

Windows Vista and 7 already include the iSCSI software, no download is necessary.
If needed, users can download free Microsoft iSCSI Initiator software at the following URL:

http://www.microsoft.com/download/en/details.aspx?id=18986

Mac OS X

Studio Network Solutions makes globalSAN iSCSI initiator, a free-to-try utility for MacOS X, available
here:

2.2 Check the accessories with your RAX-IR. Please contact CRU if any parts are missing or

damaged. The box should contain the following items:

Accessories Quantity

Ethernet Cables 2

Power Cables 2

Packet of Keys 1

Manual and Warranty Info 1

2.3 Hard Drive Installation

a) Pull the ejection handle on the TrayFree

bay to open the bay door.

b) Insert a bare SATA hard drive into the bay.

Make sure it is label-side to the left with the
SATA connection on the drive inserted first.

c) Shut the bay door.
d) You can optionally secure each bay door. Doing so is not necessary to operate RAX.

NOTE: If any of the drives are inaccessible after
powering on the unit, try the following steps:

1. Turn off the power.

2. Remove the drive(s) in question.

3. Reinsert the drive(s).

4. Turn on the power.

 Insert an RAX Key into its key lock and turn it 90 degrees clockwise.

2.4 Tips for mounting RAX840-IR

 Use a support system to mount the unit. RAX840-IR requires slide rails or other support

system to be rack-mounted. The front mounting brackets will not allow the unit to be mounted

without additional support.

 Operating temperature: Ensure that the unit is mounted in a room that is kept below 40° C (104°

F) and that the unit receives proper air flow.

 Make sure that the unit is level before securing it into place.

 Connections: Do not overload the supply circuit when connecting the equipment and ensure that

the unit is properly grounded.

3. Setting up Your RAX

The steps below explain how to get your RAX ready to use. If you purchased your RAX pre-configured,
you may skip step 3.

3.1 Connecting RAX to your network (or computer) for configuration.

a) Plug an ethernet cable into the “Config GUI” port on the rear of RAX.
b) Connect the other end of the ethernet cable to your network. Usually, this means plugging it

into a router or hub. In an office environment, you may have a network jack built into your office
wall. If a network connection is not available, you can connect the ethernet cable directly to an RJ45
(ethernet) port on your computer.

c) Connect the power cables to the rear of the RAX and to a grounded electrical outlet.
d) Turn on the RAX unit’s power using the switches on the rear panel and on the front of the unit..

3.2 Using a web browser to access the GUI (Graphical User Interface).

3.2.1 If you are connected to a DHCP-enabled
network

On DHCP networks, a new IP address is dynamically
assigned to RAX’s Config GUI port as soon as the
network detects it. You can determine this address by
checking the LCD interface on the front of RAX. It will
appear in this format: xxx.xxx.xxx.xxx. Simply type this
IP address into a web browser on your computer. This will access RAX’s GUI, which you will use to
configure the unit.

3.2.2 If you are connected to a static network
a) Check your computer’s IP address, subnet mask, and gateway. Mac users can find this information in

System Preferences  Network.

To do this in Windows, open Network and Sharing Center in the Control Panel (Also called “View Network
Status and Tasks” under the “Network and Internet” category). On the left pane, select “Change adapter
settings”. Right-click on your network (likely called Local Area Connection) and select Properties. On the
new window that opens, select “Internet Protocol Version 4 (TCP/IPv4)” and click the Properties button.
Your computer’s IP address, subnet mask, and gateway will be displayed.

b) On the RAX LCD interface, press ENT and then scroll up or down to Change IP Setting. Press ENT.

Not sure what type of network you
have? If the IP address displayed on the

LCD starts with 169.254 this indicates
that the network is probably not DHCP­enabled. Use the instructions for a static
network.

c) Scroll up or down to find Static. Press ENT.

d) Change the IP address to closely match what your computer is using. Or, if you are on a business

network, have your IT administrator assign you an IP address. The IP address you select must NOT be in

use by another device.

For example, if your computer's IP address is 192.168.0.9, you might change the RAX’s IP to

192.168.0.7. On smaller networks, each of the first three octets must be the identical to your
computer’s IP address! When changing the IP address you'll notice that a box flashes over the digit to

be changed. While the digit is selected, press ▲ (Up) or ▼ (Down) to change it. Press ENT to move to
the next digit.

e) After the IP address is set, enter the subnet mask address exactly as it is shown on your computer’s

TCP/IP settings.

f) Next, enter the gateway address exactly as it is shown on your computer’s TCP/IP settings.

g) Confirm the settings change. To confirm, press ▲ (Up) for “yes” and then press ENT again.

h) Type the RAX’s new IP address into a web browser on your computer. This will access the RAX’s GUI,

which you will use to configure the unit.

3.2.3 If you are connected directly to a computer

The instructions are similar to those for a static network (see paragraph above), except that your
computer will not have IP address assigned if it’s not a part of a network. Since the RAX and your
computer must have similar IP addresses, you will assign an IP address to your computer based on the
default IP address of RAX.

RAX840-IR Quick Start Guide A9-840-0004-1 REV 1.0 - 4 -

CRU

a) Check RAX’s LCD to find out the IP address of the Config GUI configuration port. It will appear in this

format: xxx.xxx.xxx.xxx.

b) Next, change your computer’s IP address so that all but the last three digits match RAX’s address. For

example, if RAX’s IP is 169.254.12.62, you might assign your computer the number 169.254.12.63
(assuming no other computer on the network is already using that number). The process of changing
your computer’s IP address varies depending on its operating system. (For Windows XP, open Network
Connections in the Control Panel. Right-click on your network and select Properties. On the new window
that opens, select TCP/IP and click the Properties button. Mac users can go to System Preferences 
Network.) By default, your computer is probably set to receive a new IP address automatically. Change
the setting to manual configuration and then type in the IP address.

c) Using the same process as the previous step, change the computer’s Mask setting to match RAX’s

Mask setting.

d) Finally, use RAX’s LCD interface to change RAX’s Gateway setting. It should match the IP address

you assigned to your computer.

e) Launch a web browser and type RAX’s IP address into the URL bar, as if it were a website. This will

access RAX’s GUI, which you will use to configure the unit.

The tables below show example settings. The table on the left shows the type of settings that will appear
by default. The table on the right shows how the settings might look after you’ve made changes.

3.3 Using the GUI to configure the RAID.

(You may skip this step if you purchased a pre-configured unit.)

You will use the web browser-based GUI to set up a RAID and create logical volumes on RAX. After
accessing the GUI the GUI’s main page should load, displaying a picture of RAX with several options to
the left. When you click on any option, you will be prompted for a user name and password. The user

name is "admin" and the default password is "1234."

3.4 Manually Creating a Usable RAID Set

To manually create a usable RAID set, you will first need to create a new RAID Group.

a) Click the “Create” button at the bottom of the page to open the RAID Group creation screen.

b) Enter a name for the new RAID Group in the first field, and then select your desired RAID type or

JBOD from the dropdown box. CRU-DataPort recommends RAID 5 for maximum performance,
capacity, and security. For more information on RAID, see Section 3. Click “Select PD” to select
the drives that will be added to the RAID Group.

3.5 Manually Creating a Virtual Disk

After a RAID Group has been created, you can create associated Virtual Disks. You must create at least
one Virtual Disk to access the drives of RAX with a computer.

a) Click the “Create” button at the bottom of the page to open the Virtual Disk creation screen.

b) You will see the screen below. Fill in the information and then click “Confirm”.

c) The Virtual Disk will now display on the main Virtual Disk screen. If you have enabled an Erase

option, do not shut down or reboot RAX while the Virtual Disk is initializing or the erase process will

stop.
To finish manually creating a usable RAID set, at least one Logical Unit must be attached. Go to the
next section, “Manually Attaching a Logical Unit”.

3.6 Manually Attaching a Logical Unit

You will need to attach at least one Logical Unit to a Virtual Disk to access its RAID Group, although
multiple Logical Units can be attached to the same Virtual Disk.

a) Click the “Attach” button to attach a Logical Unit to a Virtual Disk.

b) You will see the screen below. Fill in the information. Select the Virtual Disk to which you wish to

attach a Logical Unit. The Host name can remain as an asterisk if you want any host to access
the Virtual Disk. Otherwise, change the field to limit access to specific hosts. Then select the LUN
that will be used. The default setting on this is acceptable. Finally, select the permissions that
hosts accessing this Logical Unit will have. Then click “Confirm”.

c) The main Logical Unit Screen will now display the Logical Unit you have just created. If you’ve

been following the instructions for manually creating a usable RAID set, you have now completed
setup and can now access the RAID set through iSCSI initiator software.

WARNING: Changing RAID levels will

erase any data on the drives. Make a
backup copy of any data you wish to
kee

before changing the RAID.

3.7 Quick Installation

CRU-DataPort does not recommend using the Quick Installation option to set up your RAX.
Quick Install uses all physical disks in RAX and the maximum amount of space they contain to create a
RAID Group using one Virtual Disk. There will be no space set aside for spares. If some disks are used in
other RAID Groups, Quick Install cannot be run.

3.8 Connecting RAX to your network (or computer) for data access.

 Connect RAX to a computer or network using the included Ethernet cable. Plug one cable into the

“CH-1” port. You can optionally plug a second cable into the “CH-2” port. Having multiple iSCSI
channels provides redundancy/failover and increased performance.

 If you created a second data volume during the RAID initialization process, you can access it

using a second computer connected to the “CH-2” port. Each of the two iSCSI ports allows
connection by a single computer.

3.9 Accessing RAX using iSCSI Initiator Software

This software can by launched by double-clicking on the iSCSI Initiator icon in the Administrative Tools

folder in the Control Panel.

3.9.1 Windows XP

After you launch the initiator you'll see a window with several tabs, with the "General" tab opened by
default.

a) If you have set up CHAP in the RAX GUI, input the proper information by clicking on “General” tab and

then clicking on the “Secret” button.

b) Select the "Discovery" tab. Under Target Portals, click the "Add" button and enter the IP address for

the RAX’s CH-1 or CH-2 port (depending which connection link is shown as “Up” on the NIC screen).

c) Next, select the "Targets" tab. You should see a selection for the RAX in this Targets tab.
d) Select that target and click "Log on." Leave the default settings alone and click “OK”.

If the log-on is successful you'll now be able to use the RAX just like any other disk attached to your
computer.

3.9.2 Windows Vista and Windows 7
a) After you launch the initiator, input the IP address for the RAX’s CH-1 or CH-2 port (depending which

connection link is shown as “Up” on the NIC screen.

b) Click on the “Quick Connect…” button.

If the log-on is successful you'll now be able to use the RAX just like any other disk attached to your
computer.

Note: The Quick Connect feature does not support advanced connection types like CHAP. For

instructions on connecting to an iSCSI target using advanced settings, visit the following URL:

3.10 Creating volumes over 2TB in size

Although RAX can create data volumes larger than 2TB, some older operating systems cannot access
such volumes. This is because they support only 32-bit LBA (Logical Block Addressing).
Newer operating systems should be able to use 2TB+ volumes without difficulty. You will simply need to
do one of the following two things while creating a Virtual Disk:

 Change the LBA to 64-bit
 Increase the block size to 4096

Windows

Neither of the options above will work for operating systems older than Windows XP. You need to make
more than one Virtual Disk, each less than 2000GB in size. Each Virtual Disk also needs a different LUN.

Mac OS X

Although Mac OS 10.4.x supports only 32-bit LBA, increasing the block size to 4096 will allow you to
create a 2TB+ volume that is usable by the OS.

Linux

Versions of Linux vary, but using one of the above methods may allow you to create a 2TB+ volume that
your distribution can use.

4. Usage with Mac and Windows Operating Systems

4.1 Usage with Mac OS X

4.1.1 Compatibility

RAX uses 3.5-inch SATA (Serial-ATA) hard drives only. RAX does not require drivers for operation under
Mac OS X. However, if you install a host card specifically to work with this product, that card may require
drivers. See your card’s User Manual for drivers and instructions.

4.1.2 Formatting a drive

If you purchased your RAX pre-populated with hard drives, this step should not be necessary unless you
wish to change the format or erase the drive. To format, use Mac OS X’s Disk Utility (found in the
applications folder).

a) Click on the drive in the window to the left (see picture below).
b) Click the Erase tab in the window to the right (see picture below).
c) Select the format type. Most users prefer Mac OS Extended with Journaling (HFS+), which is required

for compatibility with Time Machine (OS 10.5 or newer). If you need to use your drive with both Mac and
Windows computers, select MS-DOS File System instead.

d) Enter a name for the new volume and then click “Erase” to start the process.

4.1.4 Creating a Boot Drive

To activate this feature, you must first install OS X on the hard drive in your carrier. The easiest way to do
this is to clone an existing system drive using a utility such as Carbon Copy Cloner or Super Duper. Next,
go to System Preferences  Startup Disk. A window will list the available bootable volumes. Select the
volume from which you wish to boot. Another method is to hold down the Option key during boot up. A
screen should appear that allows you to select the volume you wish to use. This is useful if you wish to
boot from your RAX hard drive only some of the time.

5. Warnings and Notices

 Use only hard drives that are in perfect condition. Avoid using drives that have ever developed

bad sectors during previous usage. This could lead to possible device failure or loss of data.

 RAX supports SATA hard drives of various specifications and different capacities. However, we

recommend using drives of the same brand and type for optimal performance. If drives of different
capacities are used in a RAID, the capacity of the smallest drive will determine how much of each
drive is used. The additional capacity on the larger drives will not be used by the RAID.

 RAID level 0 will allow you to use the full combined capacity of the drives, and offers the best data

transfer speeds. However, RAID 0 offers no protection for the data. If one drive fails in a RAID 0,
the data on all of the drives is irretrievably lost. Before creating a RAID, investigate the various
RAID types and choose the one that is best for your needs.

 Always back up data before switching RAID types. You must reformat your drives afterwards.

 Before starting any type of hardware installation, please ensure that all power switches have been

turned off and all power cords have been disconnected to prevent personal injury and damage to
the hardware.

 To avoid overheating, RAX should be operated in a well-ventilated area and in such a way that

sufficient airflow is maintained across the controller chips.

 Remove the drives before transporting RAX to prevent damage to the drive interfaces.
