Understanding Exchange 2010 Multi-Tenancy
適用版本: Exchange Server 2010 SP2
上次修改主題的時間: 2011-11-17
With the multi-tenant support built in to Microsoft Exchange Server 2010 Service Pack 1 (SP1), service providers that use Service Provider Licensing Agreement (SPLA) no longer need a solution like Hosted Messaging and Collaboration (HMC) to host multiple organizations. Multi-tenant support provides the core features of Exchange in a manner that can be deployed to multiple customers in a single installation and are easily manageable to end users.
The multi-tenant solution available for Exchange 2010 SP1 includes most of the features and functionality available in Exchange 2010 SP1 Enterprise deployments. However, this solution also includes features and functionality that will allow you to create and manage tenant organizations.
Microsoft Exchange Server 2010 SP1 will form part of the suite of multi-tenant capable products that will replace the Hosted Messaging and Collaboration 4.5 solution.
The following features and functionality are unique to multi-tenant deployments:
Hosting installation When you install Exchange 2010 SP1 for multi-tenant deployments, you will run the installation from the command line and include the
/hosting
switch. Once installed, your servers will be running in Hosting Mode.Tenant organization configuration Because you will be creating and managing multiple organizations in a multi-tenant deployment, you can use cmdlets and parameters that aren't available to Enterprise deployments.

Service plans A service plan allows you to enable or disable certain features when deploying tenant organizations. Service plans simplify tenant administration by automatically setting up feature configuration and by providing automatic feature provisioning of mailboxes. In addition, service plans allow you to grant the correct set of RBAC permissions to tenants based on available features.
Mailbox plans A mailbox plan is a template that automatically populates multiple user properties and assigns default permissions to new or existing user accounts. Use mailbox plans to provision accounts for a particular user population with a common default configuration.
For more information, see Understanding Service Plans and Mailbox Plans.
