# Add an Access Node for DevOps

Add a Windows or UNIX server to be the access node for the DevOps server in a managed service provider (MSP) environment. Using UNIX servers is recommended for better performance. You can add multiple access nodes.

## Before You Begin

- Verify that your environment meets the system requirements for Windows or Linux.

Important

Clients with ARM processors are not supported.

- The Git client application must be installed on the access node. To download Git, see Git Downloads.

- The Git Large File Storage (LFS) package must be installed on the access node. To download and install Git LFS, see Git Installation.

  The installation directories for both Git and Git LFS software must be included in the system environment variables, and the git executables must be accessible via the command prompt.

- Configure Git LFS for large files. Restores to Azure DevOps may fail for repositories larger than 5 GB because Azure DevOps limits pushes to 5 GB.

- To add the access node, you need the following information:

  - Host name

  - User name and password

- Review port requirements for the access node.

## Procedure

1. From the Command Center navigation pane, go to Manage > Infrastructure > Servers.

   The Servers page appears.

        Note

        If a tenant administrator performs a push installation, the software cache is selected as follows:

        - If the tenant has multiple access nodes configured for a company, they can select the cache source from the Software cache list on the Add Server screen.

        - If the tenant has one access node configured for a company, the system automatically selects it as the software cache.

     2. For OS Type, select the operating system that is installed on the server.

     3. From the Software cache list, select a pre-defined software cache.

     4. For credentials, choose one of the following options:

        - Enter the User name and Password for the server.
