Under Preferred Storage Network, select a network that will be designated to manage all iSCSI traffic.
3 Hosting storage for applications and shared folders The Automated Storage Manager (ASM) radically simplifies hosting application storage and shared folders on your HP Storage System, using storage-allocation wizards. Use storage-allocation wizards to allocate and configure storage for these applications: Application Description Notes Exchange Allocate and configure storage for one or more Exchange storage See “Using the Host an Exchange group components.
Accessing the Host an Exchange Storage Group Wizard 1. In the Actions pane, select Host an Exchange Storage Group. The Host an Exchange Storage Group Wizard welcome page opens. 2. Click Next to open the Specify Exchange Server page (see “Entering a name of a server that hosts Exchange” (page 11)).
1. Do one of the following: • Select the entire storage group (including all of its components) by checking the box next to the storage group. • Select individual storage group components by expanding the list and checking the boxes next to the components. 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.
2. Click Next to open the Choose Shared Folder Types page (see “Choosing shared folder types” (page 13)). Choosing shared folder types Use the Choose Shared Folder types page to enable the types of client protocols that are allowed to connect to the shared folder. 1. 2. Select the Share this folder as a Windows share check box to allow Windows clients and clients running the Server Message Block (SMB) and Common Internet File System (CIFS) protocols to connect to the shared folder.
Using the Host a SQL Server Database Wizard The Host a SQL Server Database Wizard automatically discovers the servers that host SQL Server and SQL Server databases on your domain, and helps you allocate and configure storage space for each database component you select: • Data file—Contains pointers to database files, storage for system tables and objects, and storage for database data and objects. • Log file—Holds all the transaction log information for the database.
1. Do one of the following: • Select all components (including all of its components) by checking the box next to the component. • Select individual database components by expanding the list and checking the boxes next to the components. You must select all the database components, including the log file, in a database if you want to run backups and/or take snapshots of the database using ASM. NOTE: ASM cannot migrate system databases; for example, ASM cannot migrate master, model, msdb and tempdb.
server. Upon completion, you can monitor and manage storage for the application through the Automated Storage Manager. After storage is allocated and configured on your HP Storage System for a remote application using the Host a User-Defined Application Wizard, do the following: • Manually migrate the remote application's data to your HP Storage System. See “Migrating user-defined application data from a remote application” (page 25) for more information.

After the allocated storage space is full (100 percent used), no further data can be stored to the space until you increase the size using the Allocate Space Wizard.
Table 5 Advanced Storage Properties items (continued) Physical storage 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%.
Table 6 Descriptions of RAID levels RAID level Description No RAID Offers no protection against disk failure. If a disk drive fails, data is lost. RAID 0 – Striping (No Fault Tolerance) Offers the greatest capacity and performance without data protection. If you select this option, you will experience data loss if a hard drive that holds the data fails. However, because no logical drive capacity is used for redundant data, this method offers the best capacity.
only; no hard limits are enforced on storage capacity as a result of setting this value. The warning is visible in these places: • A yellow warning icon appears on the application component, user-defined application, or shared folder icon in the content pane. • As an alert in the Properties window. NOTE: For shared folders and local storage applications, you can set an enforceable limit (or quota) for allocated storage, as well as a warning threshold.
NOTE: Backups and snapshots are disabled in ASM for an Exchange storage group or a SQL Server database if one or more of the components of the Exchange storage group or SQL Server database are not hosted. To host components for a storage group or database, start the Host an Exchange Storage Group Wizard or Host a SQL Server Database Wizard as appropriate, select the storage group or database, and then select the components on the Select Storage Group Components page that are not currently hosted.
