    Parameter

    Description

    Value

    Allocate public folders

    When Exchange Version is Exchange 2007 or related versions, this parameter is available.

    If Allocate public folders is enabled, the system will allocate one more LUN to Microsoft Exchange instances. This parameter is designed for the share access function. This parameter provides an easy and effective way for you to share information. If Outlook 2003 or earlier versions or Microsoft Entourage are installed on clients, those clients can connect to the Exchange server using this public folder only.

    [Example]

    Allocate public folders

    Capacity

    Storage capacity of the public folder. After Allocate public folders is enabled, this parameter is available.

    [Example]

    15 GB

    Enable SmartThin

    After this option is selected, the system creates thin LUNs. A thin LUN is allocated an initial capacity (30% of the total capacity) when created and is dynamically allocated required storage resources when its available capacity is insufficient.

    [Example]

    Enable SmartThin

    Reserve snapshot space

    After this option is selected, the system automatically selects a storage pool whose capacity is 130% of the required capacity. When you use the storage pool to create storage resources for applications, reserve sufficient space to create snapshots for applications.

    [Example]

    -

Click Next and set storage resource parameters for Microsoft Exchange.


The system will allocate optimal storage resources based on preset Microsoft Exchange parameters.

Table 4 describes storage resource parameters.

[Example]

Performance/Cost balance

Selected Storage Pool

Name of the storage pool automatically allocated by the system to a Microsoft Exchange instance.

[Example]

StoragePool001


  • High performance: The system automatically selects a RAID 6 storage pool containing SAS disks only. If such a storage pool does not exist in the system, create one.

  • Performance/Cost balance: The system automatically selects a RAID 6 storage pool containing SAS and NL-SAS disks only. If such a storage pool does not exist in the system, create one.

  • Low cost: The system automatically selects a RAID 6 storage pool containing NL-SAS disks only. If such a storage pool does not exist in the system, create one.

  • Manual selection: Users define storage pools that meet the Microsoft Exchange service requirements.

Optional: If the desired storage pool type does not exist or is unavailable, click en-us_image_0122792644.gif and modify Storage Pool Policy in the displayed dialog box, or click Create Storage Pool to create one.


Table 4 describes related parameters.


Optional: Select a host to which you want to map the instance.


note_3.0-en-us.png


  • If a mapped host is selected, the system automatically creates a LUN group, a host group, and a mapping view, and adds the LUN group and host group to the mapping view.

  • If no mapped host is selected, the system automatically creates a LUN group only. You need to manually create a host group and a mapping view for a mapped host and add the host to the mapping view. After being added to the mapping view, the host can access storage resources.

    The LUN group must contain all LUNs in the application instance.

hello dear
About Storage Mapping
Storage mapping is included with Veritas Storage Foundation for Oracle Enterprise Edition.

Storage mapping enables you to map datafiles, tablespaces, and tables to physical devices. You may obtain and view detailed storage topology information using the vxstorage_stats and dbed_analyzer commands or the Veritas Storage Foundation for Oracle GUI. You may also use the Oracle Enterprise Manager for Oracle 9i to access storage mapping information.

Access to mapping information is important since it allows for a detailed understanding of the storage hierarchy in which files reside, information that is critical for effectively evaluating I/O performance.

Mapping files to their underlying device is straightforward when datafiles are created directly on a raw device. With the introduction of host-based volume managers and sophisticated storage subsystems that provide RAID features, however, mapping files to physical devices has become more difficult.

With the Veritas Storage Foundation for Oracle Storage Mapping option, you can map datafiles to physical devices. Veritas Storage Mapping relies on Veritas Mapping Service (VxMS), a library that assists in the development of distributed SAN applications that must share information about the physical location of files and volumes on a disk.

The Veritas Storage Mapping option supports Oracle's set of storage APIs called Oracle Mapping ("ORAMAP" for short) that lets Oracle determine the mapping information for files and devices.

Oracle provides a set of dynamic performance views (V$ views) that shows the complete mapping of a file to intermediate layers of logical volumes and physical devices. These views enable you to locate the exact disk on which any specific block of a file resides. You can use these mappings, along with device statistics, to evaluate I/O performance.

You can view storage mapping topology information and I/O statistics using:

The vxstorage_stats command. This command displays the complete I/O topology mapping of specific datafiles through intermediate layers like logical volumes down to actual physical devices.

The dbed_analyzer command. This command retrieves tablespace-to-physical and table-to-physical disk mapping information for all the datafiles in a specified database. It also provides information about the amount of disk space being used by a tablespace.

The Veritas Storage Foundation for Oracle GUI. The GUI performs file mapping and displays both storage mapping topology information and I/O statistics.

In addition, you can also use the Oracle Enterprise Manager GUI to display storage mapping information after file mapping has occurred. Oracle Enterprise Manager does not display I/O statistics information. Unlike the information displayed in the Veritas Storage Foundation for Oracle GUI, the information displayed in Oracle Enterprise Manager may be "stale," that is, it may not be the latest information.
