About this guide
1 All-in-One Storage Manager All-in-One Storage Manager HP StorageWorks All-in-One Storage Manager (ASM) is a storage hosting and management tool that radically simplifies: • • • • Hosting storage for applications and shared folders, page 19 Configuring data protection, page 37 Managing storage, page 43 Monitoring storage, page 47 ASM provides storage-allocation wizards that walk you through the process of allocating and configuring storage on your HP All-in-One Storage System to host application data and
Table 2 Software support Microsoft Exchange Server 2003 and 2007 See “Using the Host an Exchange Storage Group Wizard” on page 20. File sharing services on local storage See “Using the Create a Shared Folder Wizard” on page 21. Microsoft SQL Server 2000 and 2005 See “Using the Host a SQL Server Database Wizard” on page 22. User-defined applications See “Using the Host a User-Defined Application Wizard” on page 24.
Figure 1 Application storage infrastructure NOTE: The iSCSI communication path is transparent to the application, application server, and Windows Explorer. The application, application server, and Windows Explorer believe the data is stored on the application server. So, to view the application data, you must navigate to the iSCSI LUN(s) on the application server, not the LUN(s) on your HP All-in-One Storage System, using Windows Explorer. ASM provides automated data migration for Exchange and SQL Server.
Figure 2 Shared folder storage infrastructure ASM discovers any top-level and nested shared folders on your HP All-in-One Storage System during setup and afterwards on an ongoing basis. ASM allows you to monitor and manage any top-level shared folders created on your HP All-in-One Storage System using ASM or other applications, such as Windows Explorer or the Shared Folder MMC snap-in.
Toolbar The toolbar, located just below the menu bar , is the MMC toolbar. See the MMC online help for more information. To open MMC online help, click Help in the Actions pane. Navigation pane The Navigation pane, located on the left side, allows you to quickly navigate between HP All-in-One Storage Management applications.
Menu Description Tools > Task Viewer Opens the Task Viewer, where you can view the: • Status of tasks completed or scheduled to run in the future. • All tasks that failed and the errors reported. The Task Viewer also allows you to cancel running and scheduled tasks. See “Monitoring task completion status” on page 33 for further information.
Defining user interface options ASM allows you to customize the user interface color and scale settings. Changing color settings Changing color settings customizes the color used in the content pane to display the different types of storage, volumes, and servers. Colors help distinguish the different types of storage, storage areas, and servers from each other. 1. In the Actions pane, select Tools > Options. The Configure Options window opens. 2. Click the Colors tab. 3.
All-in-One Storage Manager
2 Hosting storage for applications and shared folders The All-in-One Storage Manager (ASM) radically simplifies hosting application storage and shared folders on your HP All-in-One Storage System, using storage-allocation wizards. Use storage-allocation wizards to allocate and configure storage for these applications: Application Description Exchange Allocate and configure storage for individual Exchange storage group components.
Application Description data to your HP All-in-One Storage System” on page 34, and as described in the application’s documentation. Data Protection Create a virtual library where data from a remote system is backed up on your All-in-One Storage System. A wizard assists you in choosing size and storage allocation.
You must select all the storage group components in a storage group if you want to run backups or take snapshots of the Exchange storage group using ASM. The table below lists the action ASM will perform for each storage group component selected. Table 4 Selecting storage group components to host Action Description None Component’s check box is not selected, so ASM will not perform any action. Select check box to change action.
Accessing the Create a Shared Folder Wizard 1. In the Actions pane, select Create a Shared Folder. The Create a Shared Folder Wizard welcome page opens. 2. Click Next to open the Enter a Shared Folder Name and Description page (see Naming a shared folder). Naming a shared folder Use the Enter a Shared Folder Name and Description page to provide ASM with a name and description for the shared folder. 1. Enter the name for the shared folder.
The Host a SQL Server Database Wizard welcome page opens. 2. Click Next to open the Select a SQL Server page (see Selecting a server that hosts SQL Server). Selecting a server that hosts SQL Server Use the Select a SQL Server page to select one of the servers that hosts SQL Server discovered on your domain by the wizard. 1. Do one of the following: • Enter the host name of a server that hosts SQL (exactly as it is registered in the domain). • Enter the IP address of a server that hosts SQL. 2.
3. If you do not want ASM to delete the original files for the selected database components from the server that hosts SQL Server after it migrates the data to your HP All-in-One Storage System, clear the Delete original files after checkbox. 4. When you are done, click Next to open the Select the Database Workload Type page (see Selecting a database workload type). Selecting a database workload type Use the Select the Database Workload Type page to select the workload type for the SQL Server database.
To access the Host a User-Defined Application Wizard 1. In the Actions pane, select Host a User-Defined Application. The Host a User-Defined Application Wizard welcome page opens. 2. Click Next to open the Choose type of Application page (see Entering an application server name). Choose type of application 1.
NOTE: The number of slots needed for your virtual library will depend on your tape storage size. The number of slots backed up on your tape storage system and the number needed for your virtual library will be the same. Allocating space for components Use the Storage Allocation page in the wizards to specify the allocated space size and advanced configuration settings for each application component or shared folder listed. Default values are provided. NOTE: 15 MB is the minimum value that can be allocated.
NOTE: After storage space is allocated and configured using a wizard, only the following storage configuration settings can be changed: • Allocated space size • Percent full warning threshold • Enforce Allocated Limit (shared folders only) Once a logical disk is created, its configuration cannot be changed.
Item Description Notes Percent Full Warning Threshold The percent full value that when reached changes the storage status to Warning and issues a warning alert. The warning indicates that storage use has surpassed the percentage full value. For example, if you enter 75%, you see a warning (yellow asterisk) in the content pane when storage is at 75 percent full. The percent full warning threshold is set by default to 80%.
• For user-defined applications and shared folders (where industry-standard recommendations cannot be determined), the wizard provides default settings you can customize. Table 7 shows how the different RAID levels affect: • Performance–The speed at which data is read from and written to the hard drives. The RAID level with the best performance rating provides the fastest reads and writes. • Capacity–The available storage space on the hard drives.
RAID level Description performance is lower than RAID 5 due to parity data updating on multiple drives. It uses two disk for parity; its fault tolerance allows two disks to fail simultaneously. Usable capacity is N-2 where N is the number of physical drives in the logical array. Setting a percent full warning threshold To receive a warning alert when storage capacity reaches a specified limit, set the percent full warning threshold.
NOTE: ASM will only allow you to change the default Enforce Allocated Limit (Quota) setting after storage space is allocated for the shared folder using ASM, which is done for you when you use the Create a Shared Folder Wizard. However, this is not done if you create a shared folder using an application other than ASM, such as Windows Explorer or the Shared Folder MMC snap-in.
NOTE: You are also able to get to the Data Protection Advanced Properties tab by selecting Data Protection after you have scheduled backups. See Selecting local or alternate backup for more information on how to navigate to the Data Protection page outside of a wizard. 2. In the Data Protection Advanced Properties tab, Select Schedule backups to a virtual library to enable the backup schedule or leave unselected to suspend backups for now. 3.
Scheduling snapshots 1. On the Data Protection page in any wizard, select Modify Advanced Properties. This will open the Data Protection Advanced Properties tab. NOTE: You are also able to get to the Data Protection Advanced Properties tab by selecting Data Protection after you have scheduled backups. See Selecting local or alternate backup for more information on how to navigate to the Data Protection page outside of a wizard. 2.
NOTE: Click the Expand tree icon next to a task to view its subtasks. Select a task to view its description in the Details box on the Task Viewer. The Task Viewer has a filter drop-down menu. Each selection displays information about task-completion status for different time periods: • Show All—Displays all tasks that have been completed or failed to complete. Displays the tasks and subtasks currently being processed and all scheduled tasks.
