  1. Overview of Server Roles in Exchange Server 2010 In Exchange Server 2010, servers are installed with specific functional roles: • Hub Transport Server role • Mailbox Server role • Edge Transport Server role • Client Access Server role • Unified Messaging Server role www.NetComLearning.com

  2. Enterprise Level Fault Tolerance • Database Availability Groups • SAN hosted Databases • Personal Archives of PST files • Shadow Redundancy • Centralized access through Client Access Server arrays allow hardware load balancing www.NetComLearning.com

  3. What Is a Database Availability Group? A DAG is a collection of servers that provides the infrastructure for replicating and activating database copies. DAGs: • Require the failover clustering feature, although all installation and configuration is done with the Exchange Server management tools • Use Active Manager to control failover • Use an enhanced version of the continuous replication technology that Exchange Server 2007 introduced • Can be created after the Mailbox server is installed • Allow a single database to be activated on another server in the group without affecting other databases • Allow up to 16 copies of a single database on separate servers • Define the boundary for replication www.NetComLearning.com

  4. What Is Active Manager? Active Manager: • Runs a process on each server in the DAG • One node is the Primary Active Manager • Remaining nodes are Secondary Active Managers • Manages which database copies are active and which are passive • Stores database state information • Manages database switchover and failover processes • Does not require direct administration configuration www.NetComLearning.com

  5. How Are Databases Protected in a DAG? DB2 DB1 DB2 DB4 DB4 DB4 DB3 DB2 DB3 Continuous replication protects databases across servers in the DAG www.NetComLearning.com

  6. Understanding the Failover Process If a failure occurs, the following steps occur for the failed database: Active Manager determines the best copy to activate • The replication service on the target server attempts to copy missing log files from the best “source”: • If successful, the database mounts with zero data loss • If unsuccessful (failover), the database mounts based on the AutoDatabaseMountDial setting The mounted database generates new log files (using the same log generation sequence) Transport dumpster requests are initiated for the mounted database to recover lost messages When original server or database recovers, it determines if any logs are missing or corrupt, and fixes them if possible www.NetComLearning.com

  7. How Personal Archives Work in Exchange Server 2010 Exchange Server 2010 Personal Archives require a secondary or archive mailbox for the user The Personal Archive: • Must be in the same mailbox database as the primary mailbox • Appears as a folder in Outlook 2010 or Outlook Web App • Is indexed and searchable • Is not cached in Outlook • Can be managed using messaging records managementpolicies Personal Archives can help organizations meet legal and corporate requirements by ensuring that all messages are stored in an Exchange server mailbox www.NetComLearning.com

  8. Disaster Mitigation Options in Exchange Server 2010 www.NetComLearning.com

  9. Disaster Recovery Options for Mailbox Servers Exchange Server 2010 provides the following disaster recovery features for Mailbox servers: • Disaster recovery with DAGs • Mailbox servers in a DAG can host other server roles • Point-in-time database snapshot with lagged copy of DAG • Recovery database to recover mailboxes, folders, or items • Lower cost of DAG backup compared to existing backup www.NetComLearning.com

  10. What Is Database Mobility? Database mobility enables you to move mailbox databases between Mailbox servers To move a mailbox database to another server: • Perform a soft recovery on the database • Create the destination mailbox database • Move the database files and mount the database • Reconfigure the user mailboxes

  11. High Availability Solution for Mailbox Servers Mailbox data high availability: • Single database failover • Requires failover clustering feature • Allows up to 16 copies of each database • Allows up to 14 days for lag copies Public Folder high availability: • Leverages Public Folder replication • Is similar to previous Exchange Server versions www.NetComLearning.com

  12. What Is the Transport Dumpster? The transport dumpster: • Protects against Mailbox server failures when transaction logs have been lost • Keeps copies of all messages delivered in the transport queue (mail.que) until the transaction logs have replicated to all servers in the DAG, or until the maximum dumpster size is reached • Redelivers missing e-mail messages when a failure occurs www.NetComLearning.com

  13. How Shadow Redundancy Provides High Availability for Hub Transport Servers Edge1 Hub External SMTP Mail Server Edge2 Transport server delays message deletion until it verifies that the message has been delivered past the next hop www.NetComLearning.com

  14. Exchange 2010 integration with the Cloud • Integrates with Office 365 • On Premise Mailbox server with: • Hosted Client Access Server • Hosted Hub Transport Server • Hosted Lync Server uses on-premise mailbox DB www.NetComLearning.com

  15. Options for Integrating Exchange Server 2010 and Exchange Online Services Exchange Online Services: • Is part of the Business Productivity Online solution • Enables e-mail and calendar functionality hosted by Microsoft • Enables e-mail co-existence and migration of mailboxes and global address lists • Enables both on-premise and hosted mailboxes with Exchange Server 2010

  16. Powershell 2.0 and Exchange Management Shell • Version 2.0 provides Remote Management • Exchange Management Shell is a superset of Powershell www.NetComLearning.com

  17. What Are the Exchange Management Shell and Windows PowerShell? • The Exchange Management Shell is a command-line interface used for administering Exchange Server 2010 • The Exchange Management Shell is built on Windows PowerShell 2.0 remoting • Windows PowerShell is an extensible scripting and command-line technology that developers and administrators can use to: • Perform a specific task • Combine cmdlets to perform complex administrative tasks www.NetComLearning.com

  18. The Benefits of Remote Windows PowerShell Remote Windows PowerShell 2.0 enables: • Role Based Access Control • Client/server management model • Standard protocols allow easier management through firewalls www.NetComLearning.com

  19. Exchange 2010 provides ongoing protection through: • Discovery Group • ALL e-mails go through the Hub Transport • Domain Security filtering www.NetComLearning.com

  20. What Is the Edge Transport Server Role? The Edge Transport server role provides: Internet message delivery Antivirus and anti-spam protection Edge transport rules Address rewriting The Edge Transport server role: Cannot be deployed with any other server role Should not be a member of the internal Active Directory domain Should be deployed in a perimeter network www.NetComLearning.com

  21. Forefront Protection 2010 for Exchange Benefits of Forefront Protection 2010 for Exchange Server include: • Antivirus scan with multiple scan engines • Full support for VSAPI • Microsoft IP Reputation Service • Spam signature updates • Premium spam protection • Automated content filtering updates www.NetComLearning.com

  22. Forefront Protection 2010 Deployment Options You can install Forefront Protection 2010: • Only on an Edge Transport server or a Hub Transport server • On an Edge Transport server or a Hub Transport server and a Mailbox server When installing Forefront Protection 2010, consider: • The number of scan engines required • The types of scan engines that should be used www.NetComLearning.com

  26. What Is Domain Security? Uses mutual TLS with business partners to enable secured message paths over the Internet & shows an icon in Outlook To set up mutual TLS: • Generate a certificate request for TLS certificates • Import and enable the certificate on the Edge Transport server • Configure outbound Domain Security • Configure inbound Domain Security www.NetComLearning.com
