In SSFE 2.1, each user is assigned to a Plan. Plans are set to different storage limits depending on the requirement of the user. It is important to know when SSFE will reject file uploads because it has exceeded the set storage limit.
You can only determine if your Plan’s set storage limit will still allow you to upload files after uploading the file to the SSFE server. This means that when you upload a file, the SSFE server simply accepts the uploaded file. After the upload is finished, the SSFE server will check the file size and compute the user's current storage usage. If the total usage is more than what the Plan allows, the succeeding uploads will not be allowed.
If a user exceeds the storage limit set in the user’s Plan, the server will no longer accept file uploads. To resolve the issue, you must free up storage space for the server to continue allowing uploads.
