# Request S3 bucket

To request S3 bucket you have two options. Either you want to attach it to an existing project or you want to create a new project with S3 storage.

## Attach S3 bucket to an existing project

In that case send an email to <helpdesk@unil.ch> (with subject starting with "DCSR add S3 bucket to project") and providing the following information:

- project name
- size of the bucket in GB
- access allowed from outside UNIL (in read only mode only?) or not
- if access is allowed from outside UNIL, should it be limited to a set of IP or network ranges?

## Add S3 bucket to new project

When requesting a new project using the dedicated [web application](https://requests.dcsr.unil.ch/), on the resource information selection screen, click on advanced selection as follows:
