DataPort DataPAK™ RAID
DataPAK - Manual
The 1U Rack mount enclosure with DualPAK removable dual drive carriers is ideal for
disk-to-disk backup where users can “pull” a backup snap shot at anytime. Rugged Sheet
Metal Design and Shock-mounted DualPAK multi-disk removable drive carriers for drive
protection during operation, removal, transporting and storage. Available in RAID (eSATA,
USB 2.0, FireWire 800/400) or Multilane Point-to-Point SAS/SATA JBOD.
Features
• Quadruple connectivity! DataPAK is compatible with four different interfaces:
eSATA, FireWire 800, FireWire 400 and USB.
• Sturdy steel case provides excellent heat dissipation and rugged durability.
• No RAID Initialization. DataPAK’s RAID setup is instantaneous, where some
RAID controllers can take up to 24 hours to set up a RAID 5.
• DataPAK is capable of RAIDs 0, 1, 3, 5 and 10. It is also capable of setting up
hot spares.
• Auto-switching PSU. The 220W power supply automatically switches between
115V and 220V, depending on what is needed.

Pre-Installation Steps
1.1 Package Contents
Check the accessories with your DataPAK. Please contact CRU-DataPort if any parts are
missing or damaged. The box should contain the following items:
(1) 1.8M external power cord
(1) FireWire 800 to 800 Cable
(1) Carrier accessories bag
(6) Phillips screws (black, for enclosure)
(3) DataPAK keys
(4) Phillips screws (for DataPAK Carrier)
(8) Shoulder screws with grommets
1.2 Identifying Parts
Take a moment to familiarize yourself with the parts of your DataPAK. This will help you
to better understand the remaining instructions.

2. Hard Drive Installation (Skip ahead if you purchased a pre-configured unit.)
1. Remove the four cover screws and slide the carrier cover off the DataPAK carrier to open.
2. Add the shoulder screws with anti-shock grommets to the hard drives.
3. Remove the foam from the drive connectors.
4. Connect the hard drives and secure via bottom mount screws.
5. Install the hard drive in the carrier so the shoulder grommets align with the mounting
slots. Press the drive firmly in place.
6. Slide the cover on the carrier to close and secure it with the four cover screws.
Carefully slide the carriers into the DataPAK enclosure for operation.

3. Understanding RAID
3.1 Consider your RAID type (Skip ahead if you purchased a pre-configured unit.)
A RAID (Redundant Array of Independent Disks) is an array of multiple hard drives that are
combined in a way that provides faster performance and/or data safety. Your DataPAK
unit is capable of creating and managing several different varieties of RAID. You may
choose your preferred RAID level based on factors such as disk capacity, desired data
safety, and desired performance.
3.1.1 Summary of RAID Levels
The DataPAK RAID supports RAID levels 0, 1, 3, 5 and 10. The RAID 10 is the most commonly used application for the DataPAK RAID. In RAID 10 the DataPAKs are mirrored,
allowing a DataPAK to be removed while allowing the data to be accessible.
RAID Features and Performance
RAID
Description Min.
Level
0 Also known as striping. Data distributed across
multiple drives in the array. There is no data
protection.
1 Also known as mirroring. All data replicated
on separated disks. RAID 1 is almost always
2 disks.
This is a high availability solution, but due
to the 100% duplication, it is also a costly
solution.
3 Also known as Bit-Interleaved Parity. Data and
parity information is subdivided and distributed
across all disks. Parity must be equal to the
smallest disk capacity in the array. Parity
information is normally stored on a dedicated
parity disk.
5 Also known as Block-Interleaved Distributed
Parity. Data and parity information is subdivided
and distributed across all disks. Can withstand
the failure of one drive, and 75% of drive
capacity is usable.
10 Also known Block-Interleaved Parity. Data and
parity information is subdivided and distributed
across all disk. Parity must be the equal to
the smallest disk capacity in the array. Parity
information normally stored on a dedicated
parity disk.

3.1.2 Hot Spares (Host Standby)
RAIDs 3 and 5 are two RAIDs available with DataPAK that will support hot spares. Hot
spares are drives connected as part of your RAID that are switched into operation with a
drive in the RAID fails. In other words, if you setup “3+ Host Standby” with your RAID 3
or 5, then the DataPAK will immediately rebuild the RAID in the event that a drive fails.
After the RAID has rebuilt the DataPAK will need to be powered down and the failed drive
should be replaced preferably with the same model of drive.
4. RAID Configuration (Skip ahead if you purchased a pre-configured unit.)
To set up your RAID you’ll need to use Configurator 3.0. If you have not already installed
Configurator 3.0 then follow the steps below. If it is installed on your computer then skip
below to section 4.1.2.
4.1 Configurator 3.0
4.1.1 Installing Configurator
Configurator 3.0 can be found on our webpage (http://www.cru-dataport.com/software/
configurator.php)

ible with your Mac or Windows Operating System.

DataPAK - Manual
4.1.1.1 Windows Installation
If you’ve chosen the Windows version of Configurator 3.0, a Setup Wizard will appear
on your screen. Click “Next”. After you click “Next” it will take you to a licensed
agreement for installing this software. Read over the agreement and select “I accept
the agreement”, then click “Next”. The Setup Wizard will automatically create folders
for Configurator. If you would like to install it in a different folder on your system that’s
acceptable, just click “Browse” and select a new location. Once you’ve decided on where
to store the software click “Next”. Shortcuts will automatically be installed in the Start
Menu under a subfolder called CRU-DataPort. Again, if you’d like to install this in a
different area select “Browse” and choose a different location. After you’ve decided on
where to store the program’s shortcuts click “Next”. Then you can opt to have a desktop
icon installed. Make your selection and click “Next”. After that the wizard will prompt
you to install the software and will give a brief recap of the different selections you
have made. Click “Install” and let the wizard complete your installation. Finally, you can
choose to launch the Configurator now. Click “Finish” and open up Configurator 3.0.
4.1.1.2 Mac Installation
If you’ve chosen the version of Configurator 3.0, a License Agreement will appear on your
screen. You can select “Agree” and run Configurator straight from the source, or you can
select “Save” and save the software to your Mac. CRU-DataPort recommends saving it to
your Mac as well as placing an icon on your desktop for future use.
4.1.2 RAID Setup - Using Configurator 3.0
Open Configurator 3.0. A reminder will appear
telling you to disconnect all other USB and
FireWire devices. Be sure to do that and then
select “Continue”. If configuring a RAID you’ll need
to have your drives loaded inside of the unit. When
Configurator 3.0 appears you can power on your
DataPAK.
