1 Understanding the Array Installation Procedure
To set up your array and start using the iSCSI SAN array, follow these steps:
1. Install the array in a rack. See Rack Mounting the Array on page 3.
2. Connect the array to power and the network. See Connect and Secure the Power Cables on page 1 and
Connect the Array to the Network on page 10.
3. Configure the PS Series software. First, initialize an array to make it accessible on the network. Then, either
create a group with the array as the first group member or add the array to an existing group. When you
expand a group, capacity and performance increase automatically. See Choose a Configuration Method on
page 15.
4. Start using the iSCSI SAN array. Allocate group storage space to users and applications by creating
volumes. A volume appears on the network as an iSCSI target. Use a computer’s iSCSI initiator to connect
to a volume. Once you connect to a volume, it appears as a regular disk on the computer. See Storage
Allocation on page 21.
After getting started, you can customize the group and use its more advanced features. See Where to Go After
Setting Up a Group on page 27.

2 Rack Mounting the Array
For proper operation, a PS Series storage array must be properly installed in a rack. This section contains
general electrostatic, safety, network, and installation information for PS Series arrays.
After installing the array in a rack, connect the power and network cables, as described in Chapter 3.
Before You Begin
Before installing the array:
• Read the installation safety precautions. See Installation Safety Precautions on page 3.
• Make sure the rack meets the rack requirements. See Rack Requirements on page 3.
• Make sure the array and installation location meet the environmental requirements. See Environmental
Requirements on page 4.
• Unpack the rail kit (if ordered) and make sure you have all the necessary parts and tools. The rail kit is
located in the array shipping box. You must supply your own tools. See Shipping Box Contents and Required
Hardware on page 4.
Installation Safety Precautions
Follow these safety precautions:
• Dell recommends that only individuals with rack mounting experience install an array in a rack.
• Make sure the array is fully grounded at all times to prevent damage from electrostatic discharge.
• When handling the array hardware, you must use the electrostatic wrist guard shipped with the array or a
similar form of protection.
• You need at least two people to lift the array chassis from the shipping box.
Rack Requirements
The rack and the array installation must meet the following requirements:
• Use an industry standard, EIA-310-D compliant, four-post 19 inch rack with universal square hole or
unthreaded round hole spacing.
• The rack is rated for 540 kg (1200 pounds) static load or greater.
• The minimum rack depth is 100 cm (40 inches) from the front of the rack to the rear of the rack.
• For the ReadyRails™ II rail kits, the distance between the outside surfaces of the front and rear rack posts
(the mounting surfaces) can range from 595 mm to 914 mm (23.4” to 36.0”) for square-hole racks, 581 mm to
907 mm (22.9” to 35.7”) for round-hole racks and 595 mm to 929 mm (23.4” to 36.6”) for threaded-hole
racks.
• The rack is secured to the floor for added stability.
• Load a rack with arrays from the bottom to the top.
• There is at least 4.1 cm (1.6 inches) between the rack door and the front of the array to accommodate the
array front bezel.
• The rack (with installed arrays) meets the safety requirements of UL 60950-1 and IEC 60950-1, available at
http://ulstandards.

Installation and Setup Guide
• Mount the array in a horizontal orientation, or you will void your array warranty and support contract.
2 Rack Mounting the Array
Environmental Requirements
The rack location must meet the following environmental requirements:
• The power source can supply a voltage range of 100V to 240V AC.
• The power source has sufficient electrical overload protection:
In North America, connect the array to a source of power with over-current protection provided by a
double pole 20A or less device (UL 489 circuit breakers).
In Europe, the over-current protection must be provided by a 20A or less device (IEC circuit breakers).
• There is sufficient space for air flow in front of and behind the array.
• The location is properly vented.
• Your environment supports all of the requirements listed in the Technical Specifications on page 29.
Protecting Hardware
Protect your PS Series array from electrostatic discharge. When handling array hardware, use an electrostatic
wrist strap or a similar form of protection. To use a wrist strap:
1. Connect the steel snap on the coil cord to the stud on the elastic band. See Figure 1.
Figure 1: Using an Electrostatic Wrist Strap
2. Fit the band tightly around your wrist.
3. Connect the band to ground. You can either plug the banana connector into a matching grounded receptacle,
or attach it to the matching alligator clip and connect the clip to a grounded device. Examples of an
appropriate ground would be an ESD mat, or the metal frame of a grounded piece of equipment.
Shipping Box Contents and Required Hardware
Make sure you have all the items supplied in the shipping box, described in Table 1. You must provide additional
hardware that is specific to your environment and not included in the shipping box. See Table 2.

1. Determine where to place the mounting rails in the rack.
2. Attach the mounting rails to the rack.
3. Slide the chassis into the rack.
4. Attach the chassis to the front of the mounting rails.
5. Install the bezel.
These steps are described in detail in the following sections.
2 Rack Mounting the Array
Determine Where to Place the Mounting Rails in the Rack
Make sure there is enough space in the rack for the chassis. In a standard rack, a 2U chassis will span six holes.
Installing the Rails and Array in a Rack
Install the rails in the rack following the safety instructions and the rack installation instructions provided with
your rail kit.
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, make sure you install the equipment in an environment compatible
with the maximum ambient temperature (Tma) specified by the manufacturer. For more information, see
Technical Specifications on page 29.
Slide the Chassis into the Rack

4 Software Configuration
Using the Remote Setup Wizard to Configure the Software
The Remote Setup wizard is located on the Host Integration Tools CD-ROM and must be installed on a
Windows computer. The Host Integration Tools User Guide provides detailed information about using the full
capabilities of the Remote Setup Wizard.
To run the Remote Setup Wizard, follow these steps:
1. Use a computer that meets the requirements in Choose a Configuration Method on page 15.
2. Obtain the Host Integration Tools CD-ROM from the shipping box, or download the Host Integration Tools
kit from the support website.
3. Install the Remote Setup Wizard following the instructions in the Host Integration Tools documentation.
4. Start the Remote Setup Wizard by clicking:
Start, Programs, EqualLogic, Remote Setup Wizard
5. In the Welcome dialog box, select Initialize a PS Series array and click Next.
Note: If you cannot contact the array, check the network configuration. You may need to use the setup
utility to configure the software.
6. Select the array that you want to initialize and click
Next.
7. In the Initialize Array dialog box, enter the array configuration from Table 6 and choose to create a group or
join an existing group. Then, click
Next.
8. In the Create a New Group or Join an Existing Group dialog box, enter the group configuration from Table 7
and click
9. Click
Next.
Finish to exit the wizard.
If you added the array to an existing group, you must set the member’s RAID policy in order to use the disk
storage. Go to Set the Member RAID Policy on page 18.
If you created a new group, go to Chapter 5, Storage Allocation.
Set the Member RAID Policy
The storage space in a new group member (array) is not available until you configure a RAID policy on the
member.
A RAID policy consists of a RAID level and a spare disk configuration. When you select a RAID policy, the
member’s disks are automatically configured with the selected RAID level and the appropriate number of spare
disks.
If you used the Remote Setup Wizard to create a group, the RAID policy for the first member is set according to
your RAID policy selection when configuring the software, and the storage is ready to use. See Storage
Allocation on page 21.

Page 25
Installation and Setup Guide 4 Software Configuration
If you used the
setup utility to create or expand a group, or added the array to an existing group with the Remote
Setup Wizard, you must set the RAID policy for the group member.
Use either the Group Manager command line interface (CLI) or the graphical user interface (GUI) to set the
RAID policy.
Using the CLI to Set the RAID Policy
To use the Group Manager CLI to set the RAID policy for a new group member:
1. Log in to the group, if you are not already logged in. (After the setup utility completes, you will still be
logged in to the group.) Use one of the following methods to connect to the group:
– Serial connection to a member. See Set Up a Serial Connection to the Array on page 11.
– Telnet or ssh connection to the group IP address.
2. At the login prompt, enter the
group.
3. At the Group Manager command prompt, enter the following command, to specify RAID6, , RAID10, or
RAID50 for the
member select member_name raid-policy policy
policy variable:
For example, the following command configures member1 with RAID6:

– Using the GUI, expand
Volumes in the far-left panel, select the volume name, and click the Access tab.
If necessary, use the CLI or the GUI to create an access control record that the computer will match.
3. To display the iSCSI target name for the volume:
– Using the CLI, enter the following command:
volume select volume_name show
– Using the GUI, expand Volumes in the far-left panel, select the volume name, and click the Connections
tab.
4. On the computer, use the iSCSI initiator utility to specify the group IP address as the iSCSI discovery
address. If the initiator supports the discovery process, it will return a list of iSCSI targets that the computer
can access.
If the initiator does not support discovery, you must also specify the target name, and, in some cases, the
standard iSCSI port number (3260).
5. Use the iSCSI initiator utility to select the desired target and log in to the target.
When the computer connects to the iSCSI target, it sees the volume as a regular disk that can be formatted using
the normal operating system utilities. For example, you can partition the disk and create a file system.
