Configuring the Mailbox Servers

3. Lesson 1: Overview of the Mailbox Server Role
2: Planning and Configuring Mailbox Servers
Demonstration: Importing Data to a User’s Mailbox

4. The Mailbox Server Role in Exchange Server 2013
2: Planning and Configuring Mailbox Servers
In Exchange Server 2013, the Mailbox Server role provides:
Hosting for mailbox databases
Hosting for public folders
Transport and message routing services:
Hub Transport service
Mailbox Transport services
Unified Messaging service
High-availability services
Mailbox Server role features enhancements such as:
Improved transaction logs for DAGs
Enhanced site resiliency
Describe the role of the Mailbox server in Exchange Server It is very important that you emphasize that the Hub Transport and Unified Messaging roles are now integrated within the Mailbox server.

5. 20341B
How the Mailbox Server Role Interacts with Clients and the Client Access Server
2: Planning and Configuring Mailbox Servers
The Hub Transport service on the Mailbox server communicates with the Transport service on the Client Access server
Describe how the Mailbox server communicates with clients and with the Client Access server. Use this diagram to describe services on both the Mailbox server and the Client Access server. Also, describe how the Client Access server interacts with clients. Do not spend too much time on describing the interaction as the Client Access server will be discussed in detail in Module 4.

6. The Mailbox Store in Exchange Server 2013
2: Planning and Configuring Mailbox Servers
Mailbox stores in Exchange Server 2013 consist of following files:
Mailbox database (.edb file)
Transaction log (.log file)
Checkpoint file (.chk)
Temporary file (Tmp.edb)
Reserve log files (E##res0001.jrs - E##res000A.log per database, where ## is the log prefix)
Administrators rarely directly interact with these files, except during backup and restore procedures
Describe the mailbox store in Exchange Server Introduce the files that make up the Exchange Server mailbox store. Explain the purpose of each file.

7. Database Log File Considerations
2: Planning and Configuring Mailbox Servers
Each change performed in a mailbox database must be logged in the transaction log file before it is committed to the database
Each transaction log file is 1 MB in size
Transaction log files are not deleted automatically
Circular logging can be used, but it is not recommended
Follow these guidelines for log files:
Regularly perform Exchange Server backups
Move transaction logs to a dedicated drive (does not apply if you are using DAGs)
Place transaction log files on a redundant disk array
Ensure enough free disk space is available on the log disk
Do not use compression on the volume with the logs
Discuss transaction log files. Explain why these files are very important, and describe their role in backup and restore procedures. Also explain what circular logging is, and why we do not recommend using it.

8. How Are Mailbox Databases Updated?
2: Planning and Configuring Mailbox Servers 1 4
Update 3
Write to DB
Discuss the process that the Mailbox server uses when it receives data, as follows:
The Mailbox server receives the message.
The Mailbox server writes the message to the current transaction log and memory cache simultaneously.
Note: If the current transaction log reaches 1 megabyte (MB) of storage, Exchange Server renames it and creates a new current transaction log.
The Mailbox server writes the transaction from memory cache to the appropriate database.
The Mailbox server updates the checkpoint file to indicate that the transaction was committed successfully to the database.
Clients can access and read the message in the database.
When time permits, identify the files from the previous slide that each step of this process affect.
Receive message 5
Client access
Write message 2 8

9. Storage Options for the Exchange Server 2013 Mailbox Server Role
2: Planning and Configuring Mailbox Servers
Disk storage options:
DAS
SAN
RAID options:
RAID 0 ― Striping
RAID 1 ― Mirroring
RAID 5 ― Striping with parity
RAID 0+1 ― Mirrored striped sets
RAID 6 ― Striping with double parity
RAID 1+0 or RAID 10 ― Mirrored sets in a striped set
JBOD
Lead a discussion about disk storage options and about RAID technologies. The students should understand the general advantages and disadvantages of each major technology. Although there are very few hard-and-fast rules, the basic concepts are the same across all implementations of these technologies.
Stress that because the Exchange Server 2013 disk I/O requirements are lower than in previous Exchange Server versions, more storage options are available. Explain that an organization should take care in ensuring that the storage option it selects meets its business and technical requirements for the Exchange Server deployment. Tools are available to approximate usage patterns, such as Load Simulator and JetStress. Explain that you can use these tools to test the suitability of various hardware configurations in your environment.

10. Importing and Exporting Data from a Mailbox Database
2: Planning and Configuring Mailbox Servers
Exchange Server 2013 allows you to export a user‘s mailbox data to a .pst file or import data to a user‘s mailbox from a .pst file
Use the following cmdlets to import or export data:
New-MailboxImportRequest
New-MailboxExportRequest
Mailbox Import Export roles must be assigned to the user that performs the operation
PST files can be located on shares
Discuss mailbox import and export features, and explain the scenarios in which you should use them. Emphasize the need to delegate the Mailbox Import Export role to someone before starting the process. Mention that .pst files can be located on network shares, and describe how you should configure the security settings on the shared folders with the .pst files.

11. Demonstration: Importing Data to a User’s Mailbox
2: Planning and Configuring Mailbox Servers
In this demonstration, your instructor will show you how to import data from a .pst file to a user‘s mailbox on the Exchange Server
Leave all virtual machines running for subsequent demonstrations.
Preparation Steps
To perform this demonstration, you need to start the 20341B-LON-DC1, 20341B-LON-MBX1, 20341B- LON-CAS1, and the 20341B-LON-CL1 virtual machines. Start each machine and sign in to it before starting the next virtual machine. Sign into all virtual machines using the Adatum\Administrator account with the password Pa$$w0rd.
Important: Ensure that you start your virtual machines at least ten minutes prior to conducting the demonstration.

13. Lesson 2: Planning the Mailbox Server Deployment
2: Planning and Configuring Mailbox Servers
Verifying Mailbox Server Role Performance

14. Planning Hardware for the Mailbox Server Role
2: Planning and Configuring Mailbox Servers
When planning hardware for Exchange Server 2013, consider the following:
CPU:
Must be 64-bit
Multicore recommended
One core per 1,000 active mailboxes
Memory:
Minimum 8 GB per Mailbox server
3 MB per mailbox per 50 messages/day
Discuss planning of hardware requirements for Mailbox servers. Advise the students on how they should calculate CPU and memory requirements for the Mailbox server role.

15. Planning Storage for the Mailbox Server Role
2: Planning and Configuring Mailbox Servers
Consider the following when planning for Exchange Server storage:
Replicated database copies increase the amount of storage required
Slower disks have a lower cost per GB than faster disks
DAS is significantly less expensive than a SAN
JBOD can be considered when there are three or more replicas of a database
There are typically fewer database copies when a SAN is used
Use RAID to increase redundancy
Use the Exchange Server Mailbox Server Role Requirements Calculator
At the end of this topic, the students should understand that if they are using a DAG with at least three database copies, then they can consider using DAS with JBOD. If they implement DAS with JBOD, it is typically much less expensive than using a SAN for reliability.
If the students use JBOD, they need to monitor for disk failures. If a disk fails, replace the disk and add the database copy back to the new disk. Effective monitoring is critical.
The lower-speed SAS drives cost about the same as SATA drives, but SAS drives are more reliable.

16. Database Design for Mailbox Databases
2: Planning and Configuring Mailbox Servers
When designing databases, you should consider:
Use split log files and database storage to enhance recoverability when replication is not used
Allocate space for indexes
Allocate space for single-item recovery
Allocate space for personal archives
Allocate space for a recovery database
This topic covers the following general categories relating to database configuration:
Enhancing recoverability. Split log files and databases (not required if you are not restoring from backup).
Allocating sufficient disk space. Indexes, recovery databases, single-item recovery/litigation hold, and personal archives.

17. Planning Mailbox Servers for High Availability
2: Planning and Configuring Mailbox Servers
You can implement high availability for Mailbox servers by using DAGs
Consider the following when planning DAGs:
Mailbox database names must be unique in the organization
Storage paths must be identical for all copies of a database
DAGs require the failover clustering feature in Windows Server
DAGs can be managed completely with Exchange Server 2013 tools
DAGs can also protect public folders
DAGs are the method used to implement high availability for Mailbox servers in Exchange Server DAGs only support Mailbox server roles, but can be combined with other server roles. If the students are familiar with Exchange Server 2007, you can mention that the Exchange Server high-availability methods, such as Local Continuous Replication (LCR) and Cluster Continuous Replication (CCR), have been removed in Exchange Server If they are familiar with Exchange Server 2010, they probably already know about DAGs.
A DAG does not require a special edition of Exchange Server 2013; it can be implemented with Exchange Server 2013 Standard or Enterprise editions. Emphasize that DAGs also protect public folders in Exchange Server 2013.
This topic does not completely cover high availability for Mailbox servers. A module later in this course is devoted to high availability for all server roles, and includes more in-depth coverage of DAGs.

18. Virtualizing Mailbox Server Considerations
2: Planning and Configuring Mailbox Servers
Both Exchange Server 2013 server roles can be virtualized
When implementing Exchange Server 2013 on the virtual machine, consider the following:
Exchange Server 2010 has the same hardware requirements in a virtualized environment
Do not use dynamic memory
Limit virtual processor allocation to a ratio of 2:1
Do not dynamically expand virtual disks
Do not use differencing or snapshots
Test virtual disk performance
Use pass-through and iSCSI storage if desired
You can combine virtual machine high-availability methods with Exchange Server 2013 high-availability methods
All server roles for Exchange Server 2013 can be virtualized, and that is commonly done. However, it is important to make sure that the virtual machines with Exchange Server 2013 meet the same hardware specifications as physical computers that you would use for Exchange Server The slide provides some guidance for configuring the virtual machine hardware.
You may want to show the students the Server Virtualization Validation Program web page. It may be interesting for them to see the wide variety of virtualization platforms that are supported.
Also mention that you can combine virtual machine high-availability methods with Exchange Server high-availability methods, such as a DAG.

19. Considerations for Planning Mailbox Databases
2: Planning and Configuring Mailbox Servers
When planning mailbox databases, first determine whether you will deploy standalone mailbox servers or DAGs
Based on this choice, you determine:
Backup policies
Mailbox database size
Database and transaction log locations
Storage solutions
Discuss how you should plan mailbox database design in scenarios when you are using DAGs and when you are not using DAGs. Also discuss some common considerations for planning mailbox databases.

20. What Is an Exchange Mailbox Server Role Requirements Calculator?
2: Planning and Configuring Mailbox Servers
Exchange Mailbox Server Role Requirements Calculator is a free tool from Microsoft that helps you design your Mailbox server deployment
User inputs are made in the following categories:
User profile
High-availability architecture
Server's CPU platform
Storage architecture
Backup architecture
Network architecture
It provides very detailed information about requirements for mailbox servers
Provide information about Exchange Mailbox Server Role Requirements Calculator tool. Explain that this tool is actually very advanced Excel sheet created by Exchange product group.

24. Verifying Mailbox Server Role Performance
2: Planning and Configuring Mailbox Servers
To evaluate server configuration and performance:
Gather usage information
Create a test environment
Measure hardware capacity with LoadGen and Jetstress
Virtualization should not be used for performance testing unless the production environment will be virtualized
Explain that the test environment must replicate production as closely as possible. Otherwise, capacity testing is not valid. For testing of features, many of the students will be using virtualized environments. A virtualized environment is not useful for performance testing unless the production servers will also be virtualized and placed on a host with the same hardware characteristics.

34. Lab: Configuring Mailbox Servers
2: Planning and Configuring Mailbox Servers
Exercise 3: Creating and Configuring Mailbox Databases
Exercise 1: Planning Configuration for Mailbox Servers
Use the Mailbox server role calculator to design the Exchange infrastructure for A. Datum. You must fulfill the following requirements:
A. Datum has to provide mailboxes for 5,000 users. The number of mailboxes grows by a factor of 5% per year.
All users must be provided with 1-GB mailboxes. In addition, each user must have an online archive of 2 GB.
The average message size is 75 KB, and the total number of sent/received messages per mailbox per day is 150.
All deleted messages should have a retention period of 30 days, with single-item recovery enabled.
A. Datum plans to deploy four Mailbox servers.
Mailbox databases should be highly available.
Each database should have three total instances: 1 active instance, 1 passive instance, and 1 lagged copy with 24 hours delay.
Approximately 2% of mailboxes are moved per week.
Databases and logs should be separated.
A. Datum plans to implement a third-party backup solution. Backups will be performed on a weekly full/daily incremental schema.
Currently, A. Datum has only one datacenter, and at this time the company is not planning for a site- resilient solution. Servers for Exchange currently have 1,000-GB disks for databases, 500-GB disks for transaction logs, and 1,500-GB disks for Restore LUN. A. Datum also plans to leverage virtualization as much as possible.
Note: This lab uses a modified version of the Exchange Server 2010 Exchange Mailbox Server Role Requirements Calculator. Ensure that you download and use the Exchange Server 2013 version when calculating hardware requirements for Exchange Server 2013 servers.

35. 2: Planning and Configuring Mailbox Servers
Exercise 2: Configure Storage on the Mailbox Servers
Currently, the Mailbox server has no locally attached storage for the mailbox database. You have available iSCSI storage that should be used for the mailbox databases and logs. These drives will be sufficient for the initial deployment at A. Datum, but the organization expects to add several additional iSCSI drives during the deployment.
You need to configure Windows Server 2012 to connect to the iSCSI drives, and configure storage for the mailbox databases and logs.
Exercise 3: Creating and Configuring Mailbox Databases
When installing the Mailbox server role, a default mailbox database is created on the server. You need to modify the location and configuration of the default mailbox database to meet the corporate standards. The database should have a warning limit set to 0.9 GB, prohibit send at 1.0 GB, and prohibit send and receive at 2.2 GB.
In addition to the default mailbox database, you also need to create a new mailbox database to meet the deployment requirements. The new mailbox database should be placed on the iSCSI drive, and it should have circular logging enabled. You also need to set different limits and retention time periods from the default database. After setting the limits and retentions, you need to export the mailbox of Aidan Delaney to a .pst file.

Lab Scenario
2: Planning and Configuring Mailbox Servers
After performing a test deployment, A. Datum is now planning the deployment of Exchange Server in a production environment. First, they want to summarize all requirements and all available resources, and then plan for the Mailbox server deployment. After the deployment, you need to configure the storage attached to the servers, and then configure the mailbox databases. After the configuration tasks, you need to export data from the user’s mailbox to the .pst file.

Why would you choose to use SATA drives instead of a SAN or small computer system interface (SCSI) drives for your Mailbox servers?
Answer
SATA drives are much less expensive than a SAN or SCSI drive for data storage. However, they do have lower performance, at least in part due to slower spindle speeds. Exchange Server 2013 makes it possible to consider using lower performing SATA drives because of changes to the store that improves disk performance.
