### Resource Connection Limits

Depending on your operating system, you may be limited in the number of resources to which you can connect. This limit is known as the file descriptor limit. Standard limits are as follows:

* Linux-based: 1,024 resources
* MacOS: 256 resources
* Windows: 512 resources

Note the following potential scenarios that may occur if you reach the limit for your OS:

* If you run `sdm connect --all` and the number of resources you currently have access to is greater than the standard limit for your OS, the operation may fail.
* If you run `sdm connect --filter` and the number of results for that filter is greater than the standard limit for your OS, the operation may fail.

For more information on the use of filters in the CLI, see the [Filters](/references/cli/filters.md) documentation.
