+===== Connection =====
+Currently, you have to SSH directly on one of the compute node, either server [[infra:chacha|Chacha]] or [[infra:disco|Disco]] :
+  $ ssh firstname.lastname@disco.hevs.ch
+  $ ssh firstname.lastname@chacha.hevs.ch
+** NOTE : Please note you have to connect from the school network or the HEVS VPN to be able to connect on those servers **
+TODO : Change doc when the jump host will be ready
 ===== Environment =====
-On either server [[infra:chacha|Chacha]] or [[infra:disco|Disco]], you have a symlink **datasets** in your home directory that is linked to the local storage of the server : its purpose is to give you a proper space to put all the data you will be working on.

+. Your .bashrc / .zshrc contains by default the variable **APPTAINER_TMPDIR** set to **/home/user.name/.apptainer/** : this allows you to build containers without using the system /tmp that is restricted with a low quota, and use your larger dataset quota instead.
-NOTE : By default, you are the only one seeing your data : If you are working as a team on these data, **please ask for a group creation** so we can add members in it and apply suitable permissions.

+==== Quotas ====
+  - The root filesystem (/, including /home) for every researchers is 20GB for convenience. For students, this quota is lowered to 10GB to encourage proper infrastructure usage / coding with a lower threshold.
