1 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 information on connecting a PS Series array to your network and to power. See Chapter 2, Hardware Installation. 2. 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.
2 Hardware Installation The first step in using your PS Series array is to install the hardware. This chapter contains the following general electrostatic safety and network information, and installation information for PS4000 arrays. After installing the array hardware, you can configure the software, as described in Chapter 3, Software Configuration. Protecting Hardware Protect a PS Series array from electrostatic discharge.
Installation and Setup Network Requirements and Recommendations Network Requirements and Recommendations The minimum network configuration for a PS Series array consists of a connection between Ethernet 0 on each control module and a computer or a network switch. To increase performance and availability, configure multiple network interfaces on an array and connect them to multiple switches. Network recommendations are described in Table 2-1.
Installation and Setup Network Requirements and Recommendations Table 2-1: Network Recommendations (Continued) Recommendation Description No STP functionality If possible, do not use Spanning-Tree Protocol (STP) on switch on switch ports that ports that connect end nodes (iSCSI initiators or array network connect end nodes interfaces).
Installation and Setup Installing a PS4000 Array Installing a PS4000 Array Figure 2-2 shows the front view of a PS4000 array, which is a 3U array with 16 drive slots, two power supply and cooling modules, and two control modules of the same type; either two Type 8 or two Type 9 control modules. Figure 2-3 shows the rear view, with two Type 8 control modules.
Installation and Setup Installing a PS4000 Array Environmental Requirements You must meet these environmental requirements for a PS4000 array: • Only operate an enclosure from a power source with a voltage range of 100 to 240 VAC. • Make sure each power source has sufficient electrical overload protection. • Make sure there is sufficient space for air flow in front of and behind the array. • Make sure the location is properly vented.
Installation and Setup Installing a PS4000 Array Shipping Box Contents and Required Hardware Make sure you have all the items supplied in the shipping box, described in Table 2-3. This information is also listed on the Unpacking document in the shipping box. You must also provide additional hardware that is specific to your environment and not included in the shipping box. See Table 2-4.
Installation and Setup Installing a PS4000 Array Table 2-4: Required Hardware – Not Supplied Component Description Standard 19 in. fourpole rack Provides easy access to arrays and other hardware in your computing environment. Two to four network cables Connects an array to a network switch. Use Category 5E or Category 6 cables with RJ45 connectors. Use Category 5 cables only if they adhere to the TIA/EIA TSB95 standard. Connect at least one port on each control module to the network switch.
Installation and Setup Installing a PS4000 Array 2. Connect the array to the network. See Step 2: Connect the Array to the Network on page 2-9. 3. Turn on power to the array. See Step 3: Turn on Power to the Array on page 212. 4. Configure the array: • If you plan to use the setup utility, see Step 4: Set Up a Serial Connection to the Array on page 2-12. • If you plan to use the Remote Setup Wizard, see Chapter 3. The following sections describe the installation steps in detail.
Installation and Setup Installing a PS4000 Array Figure 2-4: Recommended Power Configuration - PS4000 Step 2: Connect the Array to the Network The PS4000 array includes two control modules of the same type and color. Each control module has two Gigabit iSCSI network interface ports, labeled Ethernet 0 and Ethernet 1, and one 10Mb/100Mb port labeled Management. The management port cannot carry iSCSI traffic. Use the management port only if you configure a management network.
Installation and Setup Installing a PS4000 Array Ethernet 0 and Ethernet 1 to different network switches connected with interswitch links. For example, if you connect cables as shown in Figure 2-5, and Ethernet 0 fails, initiators can be redirected to Ethernet 1. Figure 2-5: Recommended Single Control Module Configuration For a dual control module array, at a minimum, connect network cables to Ethernet 0 on both control modules and then connect the cables to a network switch. See Figure 2-6.
Installation and Setup Installing a PS4000 Array Figure 2-6: Minimum Network Configuration For maximum network bandwidth and availability, Dell recommends that you use four network cables to connect Ethernet 0 and Ethernet 1 on each control module to a different network switch. The switches must be connected with interswitch links that have sufficient bandwidth. See Figure 2-7.
Installation and Setup Installing a PS4000 Array Step 3: Turn on Power to the Array Before turning on power, allow sufficient time for the array to adjust to ambient temperature (for example, overnight). The power switch is located below the power plug on each power supply and cooling module. Note: Batteries will start to charge and some hardware components will start to synchronize when power is turned on. Array LEDs may indicate this ongoing activity, which is normal array behavior.
Installation and Setup Installing a PS4000 Array Figure 2-8: Connecting a Serial Cable to the Array The serial connection must have the following characteristics: • 9600 baud • One STOP bit • No parity • 8 data bits • No flow control Note: Keep the serial cable. You must use the serial cable to manage the group or a specific array if there is no network access. After completing the hardware installation, see Chapter 3, Software Configuration.
Installation and Setup Installing a PS4000 Array Serial Cable Pinout Information Figure 2-9 shows the pin locations on the DB9 connectors on the serial cable shipped with the array, and Table 2-5 lists the pinout information for the cable.
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. After completing the software configuration, you can allocate storage and start using the SAN. See Chapter 4, Storage Allocation.
Installation and Setup Software Configuration Table 3-1: Array Configuration (Continued) Prompt Description Network interface Name of a network interface on the array (eth0 or eth1) that is connected to a functioning port on a network switch. IP address Network address for the array network interface. Note: Each member must have at least one network interface on the same subnet as the group IP address.
Installation and Setup Software Configuration Table 3-2: Group Configuration Prompt Description Password for the Password that will override the factory-set group administration password (grpadmin) for the grpadmin account. The password must have 3 to 16 letters or numbers and is case-sensitive. grpadmin account Required only when creating a new group. Microsoft service user name and password (optional) CHAP user name and password used to enable Microsoft service (VSS or VDS) access to the group.
Installation and Setup Software Configuration 4. When prompted, enter the array and group configuration information from Table 3-1 and Table 3-2. Press the key to accept a default value. Enter a question mark (?) to obtain help. Specify whether to create a group with the array as the first member or add the array to an existing group. Note: There may be a short delay after entering the group IP address as the array searches the network.
Installation and Setup Software Configuration Example 3-1: Using the setup Utility Login: grpadmin Password: xxxxxxxx Welcome to Group Manager Copyright 2001 - 2009 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 Software Configuration Using the Remote Setup Wizard to Configure the Software The Remote Setup wizard 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 the Host Integration Tools CD-ROM from the shipping box, or download the Host Integration Tools kit from the support website. 2.
Installation and Setup Software Configuration Step 4: 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.
Installation and Setup Software Configuration For example, the following command configures member1 with RAID50: group1> member select member1 raid-policy raid50 Using the GUI to Set the RAID Policy For the latest information on browser support for the Group Manager GUI, see the PS Series Release Notes. To use the GUI to set the RAID policy for a member: 1. Log in to the group by entering the group IP address in a Web browser.
Installation and Setup Software Configuration Figure 3-2: 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 3-3), click Next.
Installation and Setup Software Configuration Figure 3-3: Configure Member – General Settings 5. In the Configure Member – RAID Configuration dialog box (Figure 3-4), do the following and then click Next. • Select the RAID policy. • 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 Software Configuration 6. In the Configure Member – Summary dialog box (Figure 3-5), click Finish if the member configuration is satisfactory. Click Back to make changes. Figure 3-5: Configure Member – Summary The array storage is ready to use.
4 Storage Allocation Allocating group storage space to users involves the following steps: • 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 Storage Allocation Optionally, you can set aside space for volume snapshots or configure a volume with 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 1. Log in to the group. Use one of these methods to connect to the group: • Serial connection to a member.
Installation and Setup Storage Allocation Using the GUI to Create a Volume 1. Log in to the group. Specify the group IP address in a Web browser. Then, in the login dialog box (Figure 3-1), enter the grpadmin account name and the password that you specified when creating the group. 2. In the Group Summary window, click Create volume in the Activities panel. 3. Enter the volume name and an optional description (Figure 4-1), and click Next. Figure 4-1: Create Volume – Volume Settings 4.
Installation and Setup Storage Allocation Figure 4-2: Create Volume – Space Reserve 5. Specify the iSCSI initiator name or IP address for the access control record and click Next (Figure 4-3). Figure 4-3: Create Volume – iSCSI Access 6. Review the summary information (Figure 4-4) and click Finish if the volume configuration is correct. Click Back to make changes.
Installation and Setup Storage Allocation Figure 4-4: Create Volume – Summary Step 2: Connect a Computer to a Volume When you create a volume, the PS Series group automatically generates an iSCSI target name, with the volume name appended to the end of the target name. Each volume appears on the network as an iSCSI target. An example of an iSCSI target name for a volume named dbvol is as follows: iqn.2001-05.com.equallogic.5-4a0900-2f00000-007eca92d654f160-dbvol To connect a computer to a volume: 1.
Installation and Setup • Storage Allocation 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.
