Scale to 100 databases per server
Exchange Server 2013 Enterprise can scale to 100 databases per server. Exchange has gained new capabilities over the years. See what’s included in this version and what’s new in Exchange Server 2013.
Remain in Control with :
- Simplified administration
A single web-based interface with the Exchange Administration Center for all Exchange services on-premises and online.
- Robust and flexible command-line tools
Reduced complexity through PowerShell scripting
- Large low-cost mailboxes
Support for larger mailboxes while deploying less expensive storage
- Role-based administration
Role-based access control and delegation of tasks
- Cloud on your terms
Deploy mailboxes on-premises, online or both with a hybrid deployment
- Managed availability across all roles and services
Integrated high availability solution monitors and manages service availability end-to-end
There are now only two roles: the Mailbox server role and the Client Access server role.
- The Mail Server Role
- The Client Access Server Role
Managed availability is a monitoring and recovery infrastructure that is integrated with Exchange’s high availability solution. Managed availability detects and recovers from problems as they occur and as they are discovered.
Data loss prevention (DLP)
DLP features include a robust set of transport rule–like tools for scanning messages for sensitive data, a predefined set of policies for common regulatory requirements, and tools for customizing the included items or building your own.
You can now perform discovery searches that include
- Exchange mailboxes
- Public folders
- Archived Microsoft Lync conversations
- Material that’s stored in Microsoft SharePoint from a single SharePoint-based interface.
Mailbox Server Changes
Exchange Replication service
Controls failover and switchover operations and database mounts and dismounts, manages the database worker processes. Failure of the Information Store service process affects only one database at a time.
Improved Exchange 2013 schema
By increasing the degree of physical and logical contiguity in the Exchange 2013 schema, fewer large I/Os will be required — but an increased amount of CPU will be needed to handle them.
The new Store also implements a new AutoReseed feature. This feature can immediately create a new passive replica of a database on a failed disk by using a spare disk on the server, automatically replacing the failed copy to maintain the correct number of copies in the database availability group.
Completely re-implemented public folders
Public folders essentially look and act like databases. Public folder databases are stored in DAGs, just as mailboxes are, so you protect public folders against outages by adding multiple replicas of a given public folder database to a DAG. Clients always connect to the active copy of the public folder, which might have implications for scalability in some environments.
Client Access Changes
Exchange 2013 no longer renders data for the client. The only thing it does is perform proxy connections from the client to the appropriate Mailbox server. This proxy-only design eliminates the need for the Client Access server to maintain affinity or state with clients, which in turn enables a much broader range of potential load-balancing solutions.
Client access protocols
Client connections can use IMAP, POP, or Exchange Web Services (EWS), but they no longer use Messaging API (MAPI) RPCs.
Clients connect to whichever Client Access server is convenient, and the Client Access server can perform HTTP redirects as necessary to find the correct Mailbox server across Active Directory (AD) sites.
The transport process has changed significantly because of the two-role architecture.
The new Front End Transport service has a completely new approach to mail acceptance and delivery: It has no permanent queues. When a new SMTP conversation is opened, the service accepts the connection, performs filtering based on the SMTP envelope data, and then determines the route to the “best” Mailbox server before starting the delivery process.
The Mailbox server runs three new transport-related services:
- The Mailbox Transport Service
- The Mailbox Transport Delivery Service
- The Mailbox Transport Submission Service
