Configuring Storage Groups and Databases on the Exchange Server

 

Topic Last Modified: 2008-02-13

This topic contains the procedures required to configure storage groups and databases on Exchange Server. In Exchange Server 2007, there is no longer the Exchange System Manager. To do the steps for Exchange 2007, you will be working with the new Exchange Management Console. For information about how to install the Exchange 2007 SP1 management tools, which includes the Exchange Management Console, see Installing the Exchange 2007 SP1 Management Tools Role.

importantImportant:
Do not use Exchange Load Generator on your production servers or environment. Use it only in test environments that do not contain mission critical information.

Before you use Exchange Load Generator to create and run tests, you must prepare the Exchange organization. For optimal performance, move your databases and log files to separate storage systems that have enough throughput so when data is written to the transaction logs and database files, the storage systems do not become a bottleneck for the test.

Additionally, you have to decide what types of scenarios to test. For example, to test scenarios in which multiple users send requests to different mailbox stores on different storage groups, you can add more storage groups and databases to the Exchange server.

To configure the Exchange server for Exchange Load Generator testing
  1. To reach optimal performance, move the transaction logs, SMTP queues, and database files to separate storage systems.

  2. Add a storage group to the Exchange server.

  3. Add mailbox stores to each storage group that is dedicated to Exchange Load Generator testing.

To configure the Exchange server for Exchange Load Generator testing, move the existing storage groups’ log files from their default location to a high throughput system.

To move the transaction log files
  1. Open Exchange System Manager: Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.

  2. In the console tree, expand Servers, and then expand the required server.

  3. Right-click the required storage group, and then click Properties.

    The First Storage Group Properties dialog box

  4. On the General tab, under Transaction log location, click Browse.

  5. Select the location of the storage system where you want the log files moved to.

  6. Click OK.

To simulate client requests to and from mailbox stores in different storage groups, you can create additional storage groups on the Exchange server. After you create the additional groups and set up the Exchange Load Generator test on the client computer, you can disperse users across storage groups to test this scenario.

To create an additional storage group on the Exchange server that has two mailbox stores
  1. Open Exchange System Manager.

  2. Expand Servers. Right-click the server you want, point to New, and then click Storage Group.

  3. In the Name box, type a new name for the storage group. For example, type Second Storage Group.

  4. Under Transaction log location, click Browse to move the log files from their default location to a separate storage system. This step is optional, but recommended. Isolating your transaction files and database files on separate storage systems prevents bottlenecks when these files are written to disk.

  5. Under System path location, click Browse to select the location of the storage system where you want the log files moved.

  6. Click OK.

This procedure explains how to create additional mailbox stores on your storage groups. Creating additional mailbox stores lets you simulate a scenario in which clients send requests to and from multiple mailbox stores.

To create additional mailbox stores on a storage group
  1. Open Exchange System Manager.

  2. Expand Servers, and then expand the server you want.

  3. Right-click the storage group that you want (for example, First Storage Group), point to New, and then click Mailbox Store.

  4. In Properties, on the General tab, in the Name box, type a name for the mailbox store. For example, type 1priv1 for the first mailbox store.

  5. Click the Database tab.

  6. Move the Exchange database files and streaming database files to a separate storage system (see screen shot). To move the Exchange database files and streaming database files to a separate storage system, do the following:

    1. Next to Exchange database, click Browse.

    2. Select the location of the storage system where you want the database files moved, and then click Save.

    3. Next to Exchange streaming database, click Browse.

    4. Select the location of the storage system where you want the streaming database files moved, and then click Save.

    noteNote:
    This step is optional, but recommended. Isolating your transaction files and database files on separate storage systems prevents bottlenecks when these files are written to disk.
  7. Click OK to create the mailbox store.

  8. In the confirmation dialog box that appears, click Yes to mount the mailbox store.

  9. Repeat Steps 4 through 8 to create and mount each additional mailbox store in the storage group.

This procedure steps through relocating the SMTP queue directory to a different drive. In some scenarios, moving the SMTP queue directory can improve the performance of the Exchange server. For more information about how to move the SMTP queue, see Microsoft Knowledge Base article 822933, “How to change the Exchange 2003 SMTP Mailroot folder location” (http://go.microsoft.com/fwlink/?LinkId=3052&kbid=822933).

To relocate the SMTP queue directory
  1. Start Exchange System Manager.

  2. Locate the SMTP virtual server whose queue directory you want to move.

  3. Right-click the SMTP virtual server, and then click Properties.

  4. Click the Messages tab.

  5. Under Queue directory, click Browse, and then select a new location for the queue data.

With Exchange 2007, there is a new Exchange Management Console for doing several administration tasks. Additionally, you can use cmdlets to do most tasks. For example, you can configure all the settings of a storage group in the Exchange Management Shell with the Set-StorageGroup cmdlet. For information about cmdlets, see the topic "Understanding Cmdlets" in the Exchange 2007 documentation (http://go.microsoft.com/fwlink/?linkid=90954).

With the Exchange Management Console, the overall steps in the procedures resemble Exchange 2003 but with a different user interface. The following are the steps that you would take to create a new storage group or configure many storage group settings.

Creating a storage group
  1. In the Exchange Management Console, expand Server Configuration, select the Mailbox node, and then click New storage group.

Configuring a storage group
  1. In the Exchange Management Console, expand Server Configuration, select the Mailbox node, right-click a storage group in the work pane, and then click Properties. Change properties as applicable.
