1 Introduction This chapter provides an introduction to PS Series storage arrays and groups and describes the steps for getting started. PS Series Arrays and Groups 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.
Installation and Setup Introduction Figure 1-1: Group With One Member To connect to a volume, a computer needs only a standard iSCSI initiator. Volume access can be restricted through IP address, initiator name, or CHAP (Challenge Handshake Authentication Protocol) credentials. Once connected, the volume is seen by the computer as a regular disk that can be formatted as usual. In a multi-member group, load balancing across members occurs automatically, as needed. Management overhead remains the same.
Installation and Setup Introduction Steps for Getting Started To set up a SAN and start using your array, follow these steps: 1. Set up the PS Series array hardware configuration. This manual includes hardware installation information for the PS5000 array and the PS5500 array. See Chapter 2, Hardware Installation. 2. Configure the PS Series software. First, initialize an array to make it accessible on the network.
2 Hardware Installation The first step in using your PS Series array is to install the hardware. This chapter contains installation information for PS5000 arrays and PS5500 arrays. • Protecting Hardware on page 2-1 • Network Requirements and Recommendations on page 2-2 • PS5000 Hardware Installation on page 2-3 • PS5500 Hardware Installation on page 2-12 After installing the array hardware, you can configure the software, as described in Chapter 3, Software Configuration.

Installation and Setup Installing Array Hardware Note: Make sure you keep the serial cable. You can use the serial cable to manage the group or array if there is no network access. Obtain the serial cable that was shipped with the array and attach the cable to the serial port on the active control module (ACT LED will be green) and to a console terminal or a computer running a terminal emulator. See Figure 2-18.
3 Software Configuration After you complete the array hardware installation, you can initialize the array and create a PS Series group with the array as the first group member. Alternately, you can add the array to an existing group. When you expand a group, capacity and performance scale automatically with no impact on users. • Step 1: Choose a Configuration Method on page 3-1. • Step 2: Collect Configuration Information on page 3-2. • Step 3: Start the Software Configuration on page 3-4.
Installation and Setup • Configuring the Software The setup utility is an interactive, command line utility that prompts for information about the array and group configuration. The only setup utility requirement is a serial connection between the array and a console terminal or a computer running a terminal emulator. See Step 4: Set Up a Serial Connection to the PS5000 on page 2-11 or Step 4: Set Up a Serial Connection to the PS5500 on page 2-23.
Installation and Setup Configuring the Software Table 3-1: Array Configuration (Continued) Prompt Description RAID policy RAID level and spare disk drive configuration for the array: • RAID 10 – Striping on top of multiple RAID 1 (mirrored) sets, with one or two spare disks. RAID 10 provides good performance for random writes, in addition to the highest availability. • RAID 50 – Striping on top of two RAID 5 (distributed-parity) sets, with one or two spare disks.
Installation and Setup Configuring the Software Step 3: Start the Software Configuration After collecting the configuration information, use the setup utility or the Remote Setup Wizard to initialize the array and either create a group with the array as the first group member or add the array to an existing group. Once you complete the software configuration, the array becomes a member of a group and its disk storage is available for use.
Installation and Setup Configuring the Software Figure 3-1: Example of the setup Utility Login: grpadmin Password: xxxxxxxx Welcome to Group Manager Copyright 2001 - 2008 Dell, Inc. It appears that the storage array has not been configured. Would you like to configure the array now? (y/n) [n] y 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.
Installation and Setup Configuring the Software 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. Obtain a computer that meets the requirements in Step 1: Choose a Configuration Method on page 3-1. 2.
Installation and Setup Configuring the Software Step 4: Set the Member RAID Policy Before you can use the storage space in a new group member (array), RAID must be configured on the member. A RAID policy consists of a RAID level and a spare disk configuration. Once the RAID policy is set, the member’s disks will be automatically configured with the selected RAID level and the appropriate number of spare disks.
Installation and Setup Configuring the Software 2. At the Group Manager command prompt, enter the following command: member select member_name raid-policy policy Specify RAID50, RAID5, or RAID10 for the policy variable. The PS5500 array supports only RAID50.
Installation and Setup Configuring the Software Figure 3-3: Group Summary – RAID Policy Is Not Set on Member 3. In the warning message dialog box that appears, click Yes to configure RAID on the member. 4. In the Configure Member – General Settings dialog box (Figure 3-4), click Next.
Installation and Setup Configuring the Software 5. In the Configure Member – RAID Configuration dialog box (Figure 3-5), do the following and then click Next. • Select the RAID policy. You will not be able to select a RAID policy that is not supported by the array model. • Optionally, to delay using the member’s storage space until the RAID verification completes and the batteries are fully charged, select Wait until the member storage initialization completes.
Installation and Setup Configuring the Software Figure 3-6: Configure Member – Summary Once you set the RAID policy, the array storage is ready to use. See Figure 3-7.
4 Storage Allocation After configuring the software, you can allocate group storage space to users. • Step 1: Create a Volume on page 4-1. • Step 2: Connect a Computer to a Volume on page 4-5. After allocating storage, you can customize the group and use its more advanced features. See Chapter 5, Where to Go Next. Step 1: Create a Volume To allocate group storage space to users and applications, use the Group Manager CLI or GUI to create volumes. A volume appears on the network as an iSCSI target.
Installation and Setup Using the SAN Optionally, you can set aside space for volume snapshots or configure a volume for thin provisioning. However, thin provisioning is not appropriate for all storage environments. See the PS Series Group Administration manual for information about advanced volume functionality. Using the CLI to Create a Volume To use the CLI to create a volume and set up access controls: 1. Log in to the group.
Installation and Setup Using the SAN Using the GUI to Create a Volume To use the GUI to create a volume, follow these steps: 1. Log in to the group. Specify the group IP address in a Web browser. Then, in the login dialog box (Figure 3-2), enter the grpadmin account name and the password that you specified when creating the group. 2. In the Group Summary window (Figure 3-7), click Create volume in the Activities panel. 2.
Installation and Setup Using the SAN 3. In the Create Volume – Space Reserve dialog box (Figure 4-2), enter the volume size and click Next. The table values will reflect the size you specify. Figure 4-2: Create Volume – Space Reserve 4. In the Create Volume – iSCSI Access dialog box (Figure 4-3), specify the IP address or iSCSI initiator name for the access control record and click Next.
Installation and Setup Using the SAN 5. In the Create Volume – Summary dialog box (Figure 4-4), click Finish if the volume configuration is satisfactory. Click Back to make changes. Figure 4-4: Create Volume – Summary Step 2: Connect a Computer to a Volume In a PS Series group, each volume appears on the network as an iSCSI target. When you create a volume, the group automatically generates an iSCSI target name, with the volume name appended to the end of the target name.
Installation and Setup Using the SAN 2. Ensure that the computer matches one of the volume’s access control records. To display the records for a volume: • Using the CLI, enter the following command: volume select volume_name access show • 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.
5 Where to Go Next After getting started, you can customize a group in order to more effectively manage your storage environment. You can also begin to utilize the full set of product features. The PS Series Group Administration manual provides details on storage concepts and how to use the Group Manager GUI to manage a group. The PS Series CLI Reference manual describes how to use the Group Manager CLI to manage a group and individual arrays.
