Manage single-session servers

For single-session servers, end users will have dedicated OS, CPU, RAM, etc., and will not be sharing those with any other users. If desired, the users can have administrative privileges to their servers.  

To view the single-session server pool list, follow the steps below.

1. Log in to the system using your credentials.
2. Click servers or the  icon in the navigation panel.
3. Click on the “single-session” tab to display the list of servers. You may filter the list or adjust the displayed columns to locate records. See the article on working with lists for more information.

Create a server pool

A server pool is a group of servers that share an image and will work as a group to deliver virtual desktops to end users.

Before a server pool can be created, it is important to have a resource group available in the same region as the server pool.

The table below shows the values that make up a server pool profile.

Field	Datatype	Required?	Notes
Name	String	Yes
Description	String	Yes
Resource group	Lookup value	Yes	List of all resource groups in the system available to the user
Server pool type	Lookup value	Yes	Unknown Personal Cyber security Pooled AD synced
Active	Boolean	Yes

To create a new server pool, follow the steps below.

1. From the Servers page, click on the “single-session” tab to access the server pools list.
2. From the top of the list, click create Server pool to trigger the Create Server pool screen.
3. Enter the appropriate values, and then click save changes to submit.
4. The new server pool will now appear in the list.

Edit a server pool

A server pool is a group of servers that share an image and configuration. In the list, server pools are left-justified and the servers within those pools are indented below them.

To edit a server pool, follow the steps below.

1. From the Servers page, click on the “single-session” tab to access the server pools list.
2. From the list, click edit on a server pool row to edit that record. To make it easier to locate the appropriate server pool, you may adjust the visible columns or filter or search through the list. See the article on working with lists for more information.

Once a server pool has been created, you can add one or multiple servers to it.

Creating a server record in Apporto does not deploy a new server, it simply adds your existing server to the Apporto interface.

The table below shows the values that make up a server profile.

Field	Datatype	Required?	Notes
Name	String	Yes
FQDN or IP address	String	No	Fully qualified domain name or IP Address of the RDP server instance This is typically used when DNS is not set up for a server instance.
RDP port	String	No	RDP Service listening port The value for this is usually 3389.
Maximum number of concurrent users	Integer	Disabled	Single session servers will be set to 1 concurrent user. This field is not editable.
