Benefits

Simplified Deployment:
You don’t have to assign services to a specific server. You just enable required functionality and SharePoint takes care of the rest.

Improved performance and reliability:
‘Improved performance and reliability’ is related to the different SharePoint services and their optimal distribution across different servers in a SharePoint farm (based on performance characteristics like CPU, memory, disk I/O, and network latency.
SharePoint ensures that services needed for each server role are running on the local server. If SharePoint needs to communicate with the service it uses the local server instead of a remote server to minimize network latency.
MinRole also scans each server to make sure they are running the services they are supposed to. If not it automatically starts and stops services to correct each server.

Simpler capacity planning and farm scalability: Capacity planning should be better predictable if your server has an exactly defined role. You don’t need to model, monitor and test what should run on which server. Adding new servers to your farm is easier since SharePoint automatically configures them. You can also convert server roles without removing servers from the farm.

Types

There are 8 server roles [1] which are combined into these 3 categories:

Dedicated roles

Dedicated roles: Dedicated roles are optimized for performance and scalability in large farms. They can be used in medium farms together with shared roles.
Server Role	Description
Front-end	Front-end servers handle user requests and are optimized for high performance.
Application	Application servers handle background tasks like timer jobs or search crawl requests. They are optimized for high throughput.
Distributed Cache	Distributed cache servers provide a high-speed cache for certain types of data like the newsfeed.
Search	Search servers handle search functionality like indexing.

Shared roles

Shared roles: Shared roles consolidate dedicated roles so they can be used in medium and small farms.
Server Role	Description
Front-end with Distributed Cache	Combines the Front-end and Distributed Cache roles on one server.
Application with Search	Combines the Application and Search roles on one server.

Special roles

Special roles: Special roles are used for test or development environments.
Server Role	Description
Single-server Farm	All services needed to run SharePoint are hosted on a single server. Its usage is limited to primarily development or testing. You can convert a single server to a multiple server farm later. This role replaces the standalone installation from previous versions. SQL Server isn’t part of the new role and you have to install it by yourself.
Custom	The custom role is basically the way Services and Service Applications were configured in SharePoint 2013. The administrator has full control (and responsibility) which service instances run on the server.

Topology and High Availability

If you have the November 2016 update installed you can now create highly available small, medium and large farms using the MinRole feature. This wasn't possible during the release of SharePoint 2016 in March 2016: The only MinRole compliant and highly available deployment included 8+ servers.

You can use dedicated roles and shared roles on their own as well as a combination of both roles. [1]

Small farm, 2 servers, No high availability

Small farm, 4 servers, high availability*

Medium farm, 6 servers, high availability*

Installation

There are 2 options for you to use the enhanced MinRole features coming with the November 2016 update:

Fresh SharePoint Installation:
If you plan to install SharePoint 2016 you can apply the November update before creating the SharePoint farm [2]:

1. Install SharePoint RTM
2. Install November 2016 update (or newer)
3. Create the SharePoint farm

Please have a look at my E-Book for a complete step-by-step SharePoint 2016 installation guide.

Update a SharePoint Installation:
You can use my free E-Book if you have a running SharePoint farm and you plan to update it.

• How to: SharePoint 2016 Updates

After you have updated SharePoint you can use the new role types when you add new servers to a SharePoint farm. You can also change the role of existing servers.
