Airavata based science gateways store data in the gateway storage which is typically mounted in the portal's hosting server. Each user's data is organized within user directories on these storage devices. As storage reaches its limits, it often creates an issue in rationing the disks. So, a single user running a finite number of experiments can adversely cause issues for other users in the gateway.

This is similar to modern memory attacks. A hacker can write a script that continuously creates new experiments causing the storage space in the gateway to be depleted.

The goal of this project is to mitigate such scenarios by implementing a storage limit for each user in a gateway. This way, one user can never adversely affect other users.
