Introduction to PS Series Storage Arrays EqualLogic PS Series storage arrays deliver the benefits of consolidated storage in a storage area network (SAN) that is affordable and easy to use—regardless of its size. With intelligent, automated management and fast, flexible scalability, PS Series arrays greatly reduce storage acquisition and management costs. This QuickStart describes how to start using your PS Series array.
PS Series 3000 QuickStart Steps for Setting Up and Using an Array At a minimum, a group consists of one array with one network connection, but you can configure three network interfaces for maximum array bandwidth. Data and network I/O are automatically load balanced across disks and interfaces—with no impact on data availability. PS Series Group With Multiple Members You can easily increase group capacity and bandwidth by adding arrays.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware Step 1. Set Up the Array Hardware A. Unpack Shipping Box and Gather Hardware The order in which you unpack the shipping box is important for safety: 1. Open the outer shipping box and remove the accessory box. 2. Remove the accessories and ensure that you have the contents shown in the figure Shipping Box Contents. 3.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware Description of Shipping Box Contents Component Description 3U storage array chassis Contains one or two control modules, two power supply/cooling modules, and eight or 16 disks. Power cables Connects an array to one or more power sources. The shipping box may contain multiple power cables to meet the electrical requirements of the country in which the array will reside.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware Array installation also requires the hardware described in Required Hardware – Not Supplied. This hardware is not provided with your array. Required Hardware – Not Supplied Component Description Standard 19” twoor four-pole rack Provides easy access to storage arrays and other hardware in your computing environment. One or more network cables Connects an array to a network switch. Use Category 5E or Category 6 cables with RJ45 connectors.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware B. Mount Array in a Stable Rack A PS Series array must be mounted in a two-pole or four-pole 19” rack. Instructions for rack assembly and mounting an array are included with the two-pole assembly kit and the four-pole assembly kit in the array shipping box. When mounting an array in a rack, you must meet the following recommendations and requirements: • Be sure there is sufficient space for air flow in front of and behind the array.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware Four-Pole Rack Example Be sure to support the array until it is completely mounted in the rack.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware C. Connect Power Cables for Grounding A PS Series array includes two power supply/cooling modules. It is recommended that you connect both power supplies to different sources of power, preferably on separate circuits for increased availability. For a highly-available power configuration, connect one power supply to an uninterruptible power supply (UPS) system, and connect the other power supply to a different source of power.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware D. Connect Array to a Network Switch A PS Series array includes one or two control modules. Only one control module is active (serving network traffic) at one time. The secondary (redundant) control module mirrors cache data from the active control module. If the active control module fails, the secondary will take over network operations.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware Network Recommendations (Continued) Recommendation Description Access to the group IP address In a multi-subnet group, each configured network interface should have access to the subnet on which the group IP address resides. Redundant network paths Using a multipathing solution helps to ensure that no single point of failure exists between hosts and arrays.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware The minimum network configuration for a single control module array is one network connection to PORT 0. The minimum network configuration for a dual control module array is one network connection to PORT 0 on each control module, as shown in the figure Minimum Dual Control Module Network Configuration. This configuration protects against control module failure.
PS Series 3000 QuickStart Step 1. Set Up the Array Hardware E. Turn on Power to Array and Check LEDs for Errors Before turning on power, be sure the array is at room temperature. If an LED indicates a problem, contact the support provider for your PS Series array.

PS Series 3000 QuickStart Step 1. Set Up the Array Hardware F. Connect Array to a Console Terminal Establish a serial connection between the array and a console terminal (or a computer running a terminal emulator) to run the setup utility, which enables you to configure the array and add it to a group. After setting up the array, the serial connection is not needed, but you should keep the serial cable. You can use a serial connection if there is no network access to the group or array.
PS Series 3000 QuickStart Step 2. Configure the Array and Create a Group Step 2. Configure the Array and Create a Group The setup utility enables you to configure a storage array on the network and create a PS Series group with the array as the first member. The utility prompts for the array’s network configuration and the group configuration, including the group IP address. Note: See the tables Network Requirements and Network Recommendations on page 9 for additional network information.
PS Series 3000 QuickStart Step 2. Configure the Array and Create a Group Group Configuration Prompt Description Group name Name of the group (up to 54 characters). Valid characters include letters, number, and dashes. The first character must be a letter or number. Identifies the group for the purposes of adding new members or setting up replication. Group IP address Network address for the group. The group IP address is used for group administration and host access to data stored in the group.
PS Series 3000 QuickStart Step 2. Configure the Array and Create a Group An example of running the setup utility is shown next. There may be a short delay after entering the group IP address as the array searches the network. Example of Configuring an Array and Creating a Group Group Manager Setup Utility The setup utility establishes the initial network and storage configuration for a storage array and then configures the array as a member or a new or existing group of arrays.
PS Series 3000 QuickStart Step 3. Set the RAID Policy Step 3. Set the RAID Policy After you create the group, use the Group Manager GUI or CLI to set the RAID policy for the member. This will configure the disks automatically according to the selected RAID policy, with the appropriate number of spare disks. Once you set the RAID policy, volume data can be stored on the member. Until the RAID configuration completes, performance will not be optimal, but the group is fully operational.
PS Series 3000 QuickStart Step 3. Set the RAID Policy If you place the mouse over the unconfigured member, the following pop-up is displayed, indicating a normal health status. Not Configured Pop-Up To set the RAID policy for the member, expand Members in the far left panel and select the member name. The following warning appears. Warning RAID Not Configured Click Yes and the Configure Member – General Settings dialog box appears.

PS Series 3000 QuickStart Step 3. Set the RAID Policy Group Summary – Completed Member Configuration Using the CLI to Set the RAID Policy To access the CLI, establish a telnet or SSH connection to the group IP address or use a serial connection to the array, as described in Step 1-F on page 15. When prompted, log in to the group by entering the grpadmin account name and the password that you specified when creating the group.
PS Series 3000 QuickStart • Step 3. Set the RAID Policy raid10-nospares — Striping on top of multiple RAID 1 sets, with no spares, if possible. This policy should be used only at installations where extra disks and personnel are available at all times to replace failed disks. Note: This option is available only with the CLI. • raid50-nospares — Striping on top of two RAID 5 sets, with no spares, if possible.
PS Series 3000 QuickStart Step 4. Create a Volume Step 4. Create a Volume After setting the RAID policy for a member, you can create one or more volumes. For each volume, you must specify: • Name. Unique name used to manage the volume, up to 64 characters. Valid characters include letters, numbers, periods, hyphens, and colons. • Size. Amount of group space to allocate to the volume. Optionally, you can override the following default snapshot settings for the volume: • Snapshot reserve.
PS Series 3000 QuickStart Step 4. Create a Volume Using the GUI to Create a Volume To start the GUI, specify the group IP address in a Web browser. When prompted, log in to the group by entering the grpadmin account name and the password that you specified when creating the group. The Group Summary window appears, displaying the current group configuration and storage pool capacity.
PS Series 3000 QuickStart Step 4. Create a Volume Create Volume – General Settings Click Next to display the Create Volume – iSCSI Access dialog box. Specify the IP address, CHAP user name, or iSCSI initiator name to which the volume will be restricted. In the following dialog box, volume access is restricted to IP address 172.17.1.40. You can set up more access controls after creating the volume.
PS Series 3000 QuickStart Step 4. Create a Volume Click Next to display the Create Volume – Summary dialog box. If the volume configuration is satisfactory, click Finish to create the volume. Create Volume – Summary Once you create a volume, you can create snapshots of the volume or perform other tasks. The following window shows a group with volumes and snapshots.
PS Series 3000 QuickStart Step 4. Create a Volume Using the CLI to Create a Volume To access the CLI, establish a telnet or SSH connection to the group IP address or use a serial connection to the array, as described in Step 1-F on page 15. When prompted, log in to the group by entering the grpadmin account name and the password that you specified when creating the group.
PS Series 3000 QuickStart Step 5. Connect to the Volume from a Host System Step 5. Connect to the Volume from a Host System A PS Series group volume is seen on the network as an iSCSI target. When you create a volume, its iSCSI target name is generated automatically. An example of an iSCSI target name for a volume named dbvol is as follows: iqn.2001-05.com.equallogic.
