Installation Guide Template - DAG Member

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

This topic provides you with an installation guide template that you can use as a starting point for formally documenting your organization's server build procedures for Microsoft Exchange Server 2010 servers that will have the Mailbox server role installed in a database availability group (DAG) configuration.

The template includes the following key sections:

• Executive Summary

• Server Configuration

• Verification Steps

• Exchange Server Role Installation

• Exchange Server Role Configuration

• Appendix: Server Configuration

For purposes of providing an example, the template uses the fictitious company name of Contoso. Also, you can download this template, along with templates for other server roles, as a download package in .zip file format at Microsoft Exchange Server 2010 Install Guide Templates (https://go.microsoft.com/fwlink/?LinkID=187961).

Executive Summary

The purpose of this document is to explain the installation and configurations necessary to install the Exchange 2010 Mailbox server role and create a database availability group (DAG) on the Windows Server 2008 platform.

Business Justification

By having an installation guide, Contoso will be able to ensure standardization across the enterprise, reducing total cost of ownership (TCO), and easing troubleshooting steps.

Scope

The scope of this document is limited to installation of an Exchange 2010 Mailbox server and creation of a database availability group (DAG) for Contoso on the x64 version of the Windows Server 2008 (SP2 or R2) operating system.

Prerequisites

The administrator should have working knowledge of Windows Server 2008 concepts, Exchange 2010 concepts, the Exchange Management Console and Exchange Management Shell, the command line, and various system utilities. This document does not elaborate on the details of any system utility except as necessary to complete the tasks within.

In addition, before implementing the server role, the administrator should review the Overview of the Mailbox Server Role topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187526).

Assumptions

This document assumes that Windows Server 2008 x64 Edition is installed on the intended Client Access server per company baseline regulations which include the latest approved service pack and hotfixes. In addition, the following system prerequisites have been installed:

• Microsoft .NET Framework 3.5 SP1 and the update for .NET Framework 3.5 SP1 For more information, see Microsoft Knowledge Base article 959209, An update for the .NET Framework 3.5 Service Pack 1 is available (https://go.microsoft.com/fwlink/?linkid=3052\&kbid=959209).

• Windows Management Framework (Windows Remote Management 2.0 and Windows PowerShell 2.0).

This document assumes that forest and domain preparation steps have been performed as described in the Prepare Active Directory and Domains topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187262).

This document assumes that the account you will be using for the Exchange tasks has been delegated the Server Management management role, as described in the Server Management topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187265).

This document also assumes that both Exchange 2010 Windows Server 2008 and Windows Server 2008 will be secured following the best practices found in the Windows Server 2008 Security Guide (https://go.microsoft.com/fwlink/?LinkId=122593).

Network Interfaces Configuration - MAPI Network

Make sure that the IP address scheme for the MAPI network is not using the same subnet or network as any replication network adapters. The MAPI network must use the subnet or network that is used to route network traffic within your intranet.

Teaming can be used on the MAPI network in redundancy mode, but it cannot be used in load balancing mode. However, even when using teaming, this does not prevent the network itself from being a single point of failure. In addition, if problems or issues occur that are related to teaming, Microsoft Customer Support Services may require you to disable teaming. If this resolves the issue, you must seek assistance from the hardware manufacturer. For more information about teaming, see Microsoft Knowledge Base article 254101, Network adapter teaming and server clustering (https://go.microsoft.com/fwlink/?linkid=3052\&kbid=254101).

If the DAG has been created, you can skip this section.

1. Make sure that there are no pending reboots for the server before adding it to a DAG.

2. Launch the Exchange Management Shell with an account that has been delegated the Organization Management role.

3. In environments where computer account creation is restricted or where computer accounts are created in a container other than the default computers container, you must pre-stage the cluster network object (CNO) and then provision the CNO by assigning permissions to it. Follow the procedures documented in the Pre-stage the Cluster Network Object for a Database Availability Group topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187665).

4. Create a database availability group by following the procedures documented in the Create a Database Availability Group topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187666).

5. Configure the database availability group properties such as the witness settings, replication port, compression, and encryption by following the procedures documented in the Configure Database Availability Group Properties topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187667).

Database Availability Group Member Server Addition

1. Launch the Exchange Management Shell with an account that has been delegated the Organization Management role.

2. Add the mailbox server to the database availability group by following the procedures documented in the Manage Database Availability Group Membership topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187669).

Database Availability Group Network Configuration

1. Launch the Exchange Management Shell with an account that has been delegated the Organization Management role.

2. When the Windows Failover Cluster is formed it will create a cluster-managed network for each subnet detected within the failover cluster. When the DAG is formed, the initial DAG network configuration is based on the enumeration of the cluster networks. If the DAG will span subnets, the recommendation is to collapse the DAG networks into a single MAPI network and a single replication network. You can do this by adding the additional subnets to the appropriate DAG networks and deleting unused networks. For example, consider the following environment:

   Sites

   • Two Active Directory sites: Exchange-1 and Exchange-2

   DAG Members

   • DAG members MBX-1 and MBX-2 located in Exchange-1

   • DAG members MBX-3 and MBX-4 located in Exchange-2

   MAPI Networks

   • MBX-1 and MBX-2 have MAPI networks on 192.168.0.0/24

   • MBX-3 and MBX-4 have MAPI networks on 192.168.1.0/24

   Replication Networks

   • MBX-1 and MBX-2 have replication networks on 10.0.0.0/24

   • MBX-3 and MBX-4 have replication networks on 10.0.1.0/24

   The database availability group networks are configured as follows:

   Network	Subnets
   DAGNetwork01	192.168.0.0/24
   DAGNetwork02	10.0.0.0/24
   DAGNetwork03	192.168.1.0/24
   DAGNetwork04	10.0.1.0/24

3. To collapse these networks, run the following commands.

   Set-DatabaseAvailabilityGroupNetwork <DAGName>\DAGNetwork01 -Subnets 192.168.0.0/24,192.168.1.0/24
   Set-DatabaseAvailabilityGroupNetwork <DAGName>\DAGNetwork02 -Subnets 10.0.0.0/24,10.0.1.0/24
   Remove-DatabaseAvailabilityGroupNetwork <DAGName>\DAGNetwork03
   Remove-DatabaseAvailabilityGroupNetwork <DAGName>\DAGNetwork04
   

4. To rename the networks according to their behavior, run the following commands.

   Set-DatabaseAvailabilityGroupNetwork <DAGName>\DAGNetwork01 -Name MAPINetwork
   Set-DatabaseAvailabilityGroupNetwork <DAGName>\DAGNetwork02 -Name ReplicationNetwork
   

5. If both MAPI and replication networks are deployed, run the following command to enable replication and seeding traffic on the replication network (unless it is unavailable).

   Set-DatabaseAvailabilityGroupNetwork <DAGName\MAPINetworkName> -ReplicationEnabled $false
   

First Database Configuration

If you provided the /mdbname, /dbfilepath, and /logfolderpath parameters when you installed the mailbox server, you can skip this section.

1. Launch the Exchange Management Shell with an account that has been delegated the Server Management role.

   Important

   The values in the following table are example values, not recommended values. Revise these values to reflect the actual values for your organization.

   First database configuration at Contoso

   Database parameter	Old	New example
   Name	Mailbox Database <GUID>	<DAGName> MBX Store 1
   Log Path	%Program Files%\Microsoft\Exchange Server\v14\Mailbox\Mailbox Database <GUID>	E:\LOG01
   Path and Filename	%Program Files%\Microsoft\Exchange Server\v14\Mailbox\Mailbox Database <GUID>\Mailbox database <GUID>.edb	E:\MDB01\Priv01.edb

2. To dismount the database, run the following command:

   Dismount-Database "Mailbox Database <GUID>"
   

3. To change the mailbox database name from “Mailbox Database <GUID>” to “<DAGName> MBX Store 1”, run the following command:

   Set-MailboxDatabase "<Old DB Name>" -Name "<New DB Name>"
   

4. To change the location of the database's transaction logs and the location of the database file, run the following command:

   Move-DatabasePath "<Database Name>" -LogFolderPath:<New Log Location> -EdbFilePath:<New DB Path and FileName>

Database / Log LUN Appendix

With mailbox resiliency, you do not have to perform daily full backups as the mailbox database copy provides the first line of defense against corruption and data loss. Therefore, there are two approaches to how backups can be performed in an environment enabled for mailbox resiliency.

• Use an Exchange-aware, Volume ShadowCopy Service (VSS) application to perform backups.

• Use Exchange Native Data Protection features as your backup methodology. For more information about Exchange Native Data Protection, see the Understanding Backup, Restore and Disaster Recovery topic in the Exchange Server 2010 Library (https://go.microsoft.com/fwlink/?LinkId=187541).

As a result of the backup methodology selected, the LUN layout has to be altered. Exchange 2010 supports the following LUN layout architectures:

• One LUN per database   A single LUN per database architecture means that both the database and its corresponding log files are placed on the same LUN. To deploy this architecture, you must have two or more copies of your databases, and you must not be using a hardware-based VSS solution.

• Two LUNs per database   With Exchange 2010, in the maximum case of 100 databases, the number of LUNs you provision will depend upon your backup strategy. If your recovery time objective (RTO) is small, or if you use VSS clones for fast recovery, it may be best to place each database on its own transaction log LUN and database LUN. This approach will exceed the number of available drive letters; therefore, volume mount points must be used.

• Two LUNs per backup set   A backup set is the number of databases fully backed up in a night. A solution that performs a full backup on 1/7th of the databases nightly (for example, using a weekly or bimonthly full backup with daily incremental or differential backups) can reduce complexity by placing all of the databases to be backed up on the same log and database LUN. This approach can reduce the number of LUNs on the server.

Two LUNs per Database / LUN Layout

Exchange 2010 uses VSS included in Windows Server 2008 to take volume shadow copies of Exchange 2010 databases and transaction log files. For basic information about VSS, including both clone and snapshot techniques, review the white paper, Best Practices for Using Volume Shadow Copy Service with Exchange Server 2003 (https://go.microsoft.com/fwlink/?LinkId=122556).

Exchange 2010 enables you to make software-based VSS snapshots of both the active and passive database copies. Taking a VSS snapshot of the passive copy offloads the disk I/O from the active LUN during both the checksum integrity (ESEUTIL), and subsequent copy to tape or disk.

Creating two LUNs (log and database) for a database was the standard best practice for Exchange 2003. With Exchange 2010, in the maximum case of 100 databases, the number of LUNs you provision will depend on your backup strategy. If your recovery time objective (RTO) is very small, or if you use VSS clones for fast recovery, it may be best to place each database on its own transaction log LUN and database LUN. Depending on the number of LUNs required, volume mount points may need to be used.

Some benefits of this strategy include the following:

• Enables hardware-based VSS at a database level, providing single database backup and restore.

• Flexibility to isolate the performance between databases when not sharing spindles between LUNs.

• Increased reliability: A capacity or corruption problem on a single LUN will only affect one database.

• This is also the recommended strategy for databases that do not participate in mailbox resiliency.

Some concerns with this strategy include the following:

• 100 databases using mailbox resiliency could require 400 LUNs which would exceed some storage array maximums. 100 databases without mailbox resiliency could require 200 LUNs which would exceed some storage array maximums.

• A separate LUN for each database causes more LUNs per server increasing the administrative costs and complexity.

LUN design approach: Two LUNs per database

DB	Database name	Database location	Database file name	Transaction log location
Anchor LUN	--	E:\	--	L:\
DBx	<DAGName> MBX DB x	MP:\MDB0x	Priv0x.edb	MP:\LOG0x
DBy	<DAGName> MBX DB y	MP:\MDB0y	Priv0y.edb	MP:\LOG0y
…	…	…	…	…

One LUN per Database / LUN Layout

Single LUN per database architecture means that both the database and its corresponding log files are placed on the same LUN. To deploy this architecture, you must have two or more copies, and you must not be using a hardware-based VSS solution.

Some of the benefits of this strategy include:

• Simplifies storage administration with fewer LUNs to manage.

• Reduces (potentially) the number of backup jobs.

• Provides flexibility to isolate the performance between databases when not sharing spindles between LUNs.

A concern with this strategy is that it limits the ability to perform hardware-based VSS backup and restore procedures (for example, clone snapshots). For VSS details, review the white paper, Best Practices for Using Volume Shadow Copy Service with Exchange Server 2003 (https://go.microsoft.com/fwlink/?LinkId=122556).

LUN design approach: One LUN per database

DB	Database name	Database location	Database file name
Anchor LUN	--	E:\	--
DBx	<DAGName> MBX Store X	MP:\ \MDBx \LOGx	PrivX.edb
DBy	<DAGName> MBX Store Y	MP:\ \MDBy \LOGy	PrivY.edb
…	…	…	…
